The Economics of Housing Supply


chart by Smallman12q

Housing economists Edward L. Glaeser and Joseph Gyourko have posted The Economic Implications of Housing Supply to SSRN (behind a paywall but you can find a slightly older version of the paper here). The abstract reads,

In this essay, we review the basic economics of housing supply and the functioning of US housing markets to better understand the distribution of home prices, household wealth and the spatial distribution of people across markets. We employ a cost-based approach to gauge whether a housing market is delivering appropriately priced units. Specifically, we investigate whether market prices (roughly) equal the costs of producing the housing unit. If so, the market is well-functioning in the sense that it efficiently delivers housing units at their production cost. Of course, poorer households still may have very high housing cost burdens that society may wish to address via transfers. But if housing prices are above this cost in a given area, then the housing market is not functioning well – and housing is too expensive for all households in the market, not just for poorer ones. The gap between price and production cost can be understood as a regulatory tax, which might be efficiently incorporating the negative externalities of new production, but typical estimates find that the implicit tax is far higher than most reasonable estimates of those externalities.

The paper’s conclusions, while a bit technical for a lay audience, are worth highlighting:

When housing supply is highly regulated in a certain area, housing prices are higher and population growth is smaller relative to the level of demand. While most of America has experienced little growth in housing wealth over the past 30 years, the older, richer buyers in America’s most regulated areas have experienced significant increases in housing equity. The regulation of America’s most productive places seems to have led labor to locate in places where wages and prices are lower, reducing America’s overall economic output in the process.

Advocates of land use restrictions emphasize the negative externalities of building. Certainly, new construction can lead to more crowded schools and roads, and it is costly to create new infrastructure to lower congestion. Hence, the optimal tax on new building is positive, not zero. However, there is as yet no consensus about the overall welfare implications of heightened land use controls. Any model-based assessment inevitably relies on various assumptions about the different aspects of regulation and how they are valued in agents’ utility functions.

Empirical investigations of the local costs and benefits of restricting building generally conclude that the negative externalities are not nearly large enough to justify the costs of regulation. Adding the costs from substitute building in other markets generally strengthens this conclusion, as Glaeser and Kahn (2010) show that America restricts building more in places that have lower carbon emissions per household. If California’s restrictions induce more building in Texas and Arizona, then their net environmental could be negative in aggregate. If restrictions on building limit an efficient geographical reallocation of labor, then estimates based on local externalities would miss this effect, too.

If the welfare and output gains from reducing regulation of housing construction are large, then why don’t we see more policy interventions to permit more building in markets such as San Francisco? The great challenge facing attempts to loosen local housing restrictions is that existing homeowners do not want more affordable homes: they want the value of their asset to cost more, not less. They also may not like the idea that new housing will bring in more people, including those from different socio-economic groups.

There have been some attempts at the state level to soften severe local land use restrictions, but they have not been successful. Massachusetts is particularly instructive because it has used both top-down regulatory reform and incentives to encourage local building. Massachusetts Chapter 40B provides builders with a tool to bypass local rules. If developers are building enough formally-defined affordable units in unaffordable areas, they can bypass local zoning rules. Yet localities still are able to find tools to limit local construction, and the cost of providing price-controlled affordable units lowers the incentive for developers to build. It is difficult to assess the overall impact of 40B, especially since both builder and community often face incentives to avoid building “affordable” units. Standard game theoretic arguments suggest that 40B should never itself be used, but rather work primarily by changing the fallback option of the developer. Massachusetts has also tried to create stronger incentives for local building with Chapters 40R and 40S. These parts of their law allow for transfers to the localities themselves, so builders are not capturing all the benefits. Even so, the Boston market and other high cost areas in the state have not seen meaningful surges in new housing development.

This suggests that more fiscal resources will be needed to convince local residents to bear the costs arising from new development. On purely efficiency grounds, one could argue that the federal government provide sufficient resources, but the political economy of the median taxpayer in the nation effectively transferring resources to much wealthier residents of metropolitan areas like San Francisco seems challenging to say the least. However daunting the task, the potential benefits look to be large enough that economists and policymakers should keep trying to devise a workable policy intervention. (19-20)

State of the Nation’s Housing 2017

Harvard’s Joint Center for Housing Studies has released its excellent State of the Nation’s Housing for 2017, with many important insights. The executive summary reads, in part,

A decade after the onset of the Great Recession, the national housing market is finally returning to normal. With incomes rising and household growth strengthening, the housing sector is poised to become an important engine of economic growth. But not all households and not all markets are thriving, and affordability pressures remain near record levels. Addressing the scale and complexity of need requires a renewed national commitment to expand the range of housing options available for an increasingly diverse society.

National Home Prices Regain Previous Peak

US house prices rose 5.6 percent in 2016, finally surpassing the high reached nearly a decade earlier. Achieving this milestone reduced the number of homeowners underwater on their mortgages to 3.2 million by year’s end, a remarkable drop from the 12.1 million peak in 2011. In inflation-adjusted terms, however, national home prices remained nearly 15 percent below their previous high. As a result, the typical homeowner has yet to fully regain the housing wealth lost during the downturn.

*     *     *

Pickup In Household Growth

The sluggish rebound in construction also reflects the striking slowdown in household growth after the housing bust. Depending on the government survey, household formations averaged just 540,000 to 720,000 annually in 2007–2012 before reviving to 960,000 to 1.2 million in 2013–2015.

Much of the falloff in household growth can be explained by low household formation rates among the millennial generation (born between 1985 and 2004). Indeed, the share of adults aged 18–34 still living with parents or grandparents was at an all-time high of 35.6 percent in 2015. But through the simple fact of aging, the oldest members of this generation have now reached their early 30s, when most adults live independently. As a result, members of the millennial generation formed 7.6 million new households between 2010 and 2015.

Homeownership Declines Moderating, While Rental Demand Still Strong

After 12 years of decline, there are signs that the national homeownership rate may be nearing bottom. As of the first quarter of 2017, the homeownership rate stood at 63.6 percent—little changed from the first quarter two years earlier. In addition, the number of homeowner households grew by 280,000 in 2016, the strongest showing since 2006. Early indications in 2017 suggest that the upturn is continuing. Still, growth in renters continued to outpace that in owners, with their numbers up by 600,000 last year.

*     *     *

Affordability Pressures Remain Widespread

Based on the 30-percent-of-income affordability standard, the number of cost-burdened households fell from 39.8 million in 2014 to 38.9 million in 2015. As a result, the share of households with cost burdens fell 1.0 percentage point, to 32.9 percent. This was the fifth straight year of declines, led by a considerable drop in the owner share from 30.4 percent in 2010 to 23.9 percent in 2015. The renter share, however, only edged down from 50.2 percent to 48.3 percent over this period.

With such large shares of households exceeding the traditional affordability standard, policymakers have increasingly focused their attention on the severely burdened (paying more than 50 percent of their incomes for housing). Although the total number of households with severe burdens also fell somewhat from 19.3 million in 2014 to 18.8 million in 2015, the improvement was again on the owner side. Indeed, 11.1 million renter households were severely cost burdened in 2015, a 3.7 million increase from 2001. By comparison, 7.6 million owners were severely burdened in 2015, up 1.1 million from 2001.

Segregation By Income on The Rise

A growing body of social science research has documented the long-term damage to the health and well-being of individuals living in high-poverty neighborhoods. Recent increases in segregation by income in the United States are therefore highly troubling. Between 2000 and 2015, the share of the poor population living in high-poverty neighborhoods rose from 43 percent to 54 percent. Meanwhile, the number of high-poverty neighborhoods rose from 13,400 to more than 21,300. Although most high-poverty neighborhoods are still concentrated in high-density urban cores, their recent growth has been fastest in low-density areas at the metropolitan fringe and in rural communities.

At the same time, the growing demand for urban living has led to an influx of high-income households into city neighborhoods. While this revival of urban areas creates the opportunity for more economically and racially diverse communities, it also drives up housing costs for low-income and minority residents.

One comment, a repetition from my past discussions of Joint Center reports. The State of the Nation’s Housing acknowledges sources of funding for the report but does not directly identify the members of its Policy Advisory Board, which provides “principal funding” for it, along with the Ford Foundation. (front matter) The Board includes companies such as Fannie Mae, Freddie Mac and Zillow which are directly discussed in the report. In the spirit of transparency, the Joint Center should identify all of its funders in the State of the Nation’s Housing report itself. Other academic centers and think tanks would undoubtedly do this. The Joint Center for Housing Studies should follow suit.

 

How Are First-Time Homebuyers Doing?

photo by designmilk

Genworth Mortgage Insurance Corporation released a a First-Time Home Market Report.  The big news from the report is that first-time homebuyers purchased fifteen percent more single-family homes in 2016 than in 2015.  The 2 million homes purchased in 2016 was the most since 2006, before the financial crisis. This is a positive sign for the housing market and for the homeownership rate which has fallen to long-time lows since the financial crisis. The Executive Summary reads,

First-time homebuyers represent an important segment of the housing market, generating significant revenue to real estate agents, homebuilders, and the mortgage finance industry. In this report, we adopt the Department of Housing and Urban Development (HUD) definition of first-time homebuyers as homebuyers who did not own a home in any of the prior three years  . . . Compared to repeat homebuyers, first-time homebuyers play a more pivotal role in influencing housing inventory and home prices because they represent the shift of housing demand from rental to owner occupancy. Despite this well-recognized dynamic, there has been limited data available on the first-time homebuyer market, starting with market size. In this report, we estimate the size of the first-time homebuyer market going back to 1994 using a combination of government and mortgage industry data—20.1 million actual first-time homebuyers were identified. This data provides a historical perspective on the first-time homebuyer market as well as important recent trends. (2)

The report’s key findings include,

1. Between 1994 and 2016, first-time homebuyers purchased on average 1.8 million single-family homes each year, accounting for over one in three of all single-family homes sold, and 45 percent of the purchase mortgages originated.

2. First-time homebuyers have led the housing recovery, contributing over 60 percent of the sales growth in the housing market over the past five years and 85 percent of the growth in the past two years. The resurgence of the first-time homebuyer market has contributed to very tight housing supplies and accelerating home prices, especially at the “low” end of the housing market.

3. During the Housing Crisis, the number of single-family homes sold to first-time homebuyers saw a peak to trough decline of 900,000 units (43 percent) – reaching a trough of just 1.2 million units in 2011. Over the last 10 years, the housing market has seen 3 million fewer first-time homebuyers in aggregate compared to the historical average.

4. The first-time homebuyer market stagnated during the historic housing expansion of the 1990s and early 2000s, leading to a decline in first-time homebuyer mix. Instead, it was repeat homebuyers, including second-home buyers and investors, who led the surge in housing activity.

5. The expansion of government lending programs and the implementation of the first-time homebuyer tax credit provided temporary support to first-time homebuyers. Between 2008 and 2010, first-time homebuyers represented 35 percent of all single-family home sales, which is close to its historical average. However, the percentage of single-family home sales to first-time homebuyers declined once the tax credit expired, and stayed below 30 percent for these three years.

6. First-time homebuyers have always demonstrated a greater need for low down payment mortgage products. Between 1994 and 2016, 73 percent of first-time homebuyers chose such products compared to 30-50 percent for repeat homebuyers. Mortgage products with a lower down payment will likely have a higher first-time homebuyer mix.

7. Private mortgage insurance and FHA (government-backed mortgage insurance) are the two leading products for first-time homebuyers and have together accounted for close to 1 million first-time homebuyers a year since 1994. They have played a key role in reviving the first-time homebuyer market in the current recovery, accounting for approximately 80 percent of its growth in the past two years.

8. First-time homebuyers purchased 2 million single-family homes in 2016, 15 percent more than 2015 – and the most since 2006. During the first quarter of 2017, there were more first-time homebuyers than any other year since 2005. A total of 424,000 single-family homes were sold to first-time homebuyers, up 11 percent from a year ago, and accounting for 38 percent of all single-family home sales. (3)

What’s the CFPB Ever Done for Housing?

TheStreet.com quoted me in What’s the CFPB Ever Done For Housing? Quite A Lot. It reads, in part,

The Consumer Financial Protection Bureau grew out of the housing market crash of 2008 and subsequent Dodd-Frank legislation. As a watchdog with teeth, the CFPB’s job is to protect homebuyers from the predatory mortgages that helped sink the economy nine years ago. And it worked.

In theory.

Problem is, for some would-be homeowners, the CFPB is an inconvenient middle-man, adding more red tape to an already impossible situation. In short, it isn’t perfect. But with the Trump administration threatening to tear the whole damn thing down, you’ve got to wonder, is the CFPB really doing more harm to the housing market than good?

How we got here

Pre-housing market crash, the mortgage lending world was a vastly different, Wild West sort of landscape. Dodd-Frank and the CFPB entered the scene, in part, for lending oversight in that uncontrolled housing market. For example, once not-uncommon ‘liar loans,’ which were largely based on the borrower’s word and not much else-for instance, someone saying they made $100,000 a year to qualify for a huge home even though they made $30,000-are now illegal thanks to Dodd-Frank and the CFPB. Mortgage companies cashing in at the expensive of uneducated buyers happened, and it happened a lot.

“Just about everybody I talked to prior to 2008 thought the lending climate was out of control,” says Chandler Crouch, broker and owner of Chandler Crouch Realtors in Dallas-Fort Worth. “People were saying it couldn’t last. It just didn’t make sense. Lending requirements were too loose. Everybody, from Wall Street to the banks to the loan officers to the consumers, was being rewarded for making bad decisions. Lending needed to tighten.”

*     *     *

“The CFPB has been criticized for restricting mortgage credit too much with its Qualified Mortgage and ability to repay rules,” says David Reiss, a law professor at Brooklyn Law School who has practiced real estate law since 1998.

This was all done to ensure buyers could afford their home and not end up in foreclosure or short sale (and also avoid another economic collapse). These rules also bar lenders from predatory loans like massive balloon loans and shady adjustable rate mortgages.

*     *     *

Will no CFPB = housing hellscape?

Let’s say the Republicans get their way and the CFPB goes poof. What happens?

“You’d see an expansion of the credit box-more people would be approved for credit,” says Reiss. “To the extent that credit is offered on good terms, that would be a good development. I think you would see more potential homebuyers being approved for mortgages which would drive up home prices in the short term as there would be more competition.”

But then there’s the opportunity for those really bad loans to come swinging back, which harm homeowners would have in the past and also trigger fears of another housing collapse.

“Liar loans would definitely have a comeback if the CFPB and Dodd-Frank were dismantled,” says Reiss. “The Qualified Mortgage and ability to repay rules were implemented as part of the broader Dodd-Frank rulemaking agenda; without those rules, credit would quickly return to its extreme boom and bust cycle, with liar loans a product that would pick up steam just as the boom reaches its heights…We would bemoan them once again as soon as the bust hits its depths.”

Retired With A Mortgage

U.S. News & World Report quoted me in Rethinking a Mortgage While Retired. It opens,

It’s one of the cardinal rules of retirement planning: pay off the mortgage before quitting work. Giving up your income while still supporting a big debt can mean chewing away at your retirement savings way too fast, and can leave you in a tight spot if something goes wrong.

But paying off a mortgage years early is easier said than done, and the Center for Retirement Research at Boston College says way too many pre-retirees are too far behind schedule, largely because of borrowing before the housing bust and financial crisis.

On the other hand, some experts say carrying low-interest debt into retirement is not always such a bad thing, especially if it means leaving money in investments that perform well.

“In 2013, almost 40 percent of all households ages 55 and over had not paid off their mortgages, up from 32 percent in 2001,” the Center reports, citing a study using data from the Federal Reserve’s Survey of Consumer Finances in 2013. “These borrowers were also carrying a lot more housing debt by 2013.”

“I’ve been advising clients for over 20 years and on just an anecdotal level, I can tell you that more clients are retiring with mortgage balances than in years past,” says Margaret R. McDowell, founder of Arbor Wealth Management in Miramar Beach, Florida.

A.W. Pickel III, president of the Midwest division of AmCap Mortgage in Overland Park, Kansas, says many baby boomers traded up as their families grew, then took second mortgages to help fund college costs.

In the years before 2008, homeowners were encouraged to take out big loans when home values appeared to be soaring, the center says. They bought expensive homes or tapped home value through cash-out refinancing or home equity loans, it says.

When home prices collapsed, millions were left “underwater” – owing more than their homes were worth – and were unable to get out from under because they could not sell for enough to pay off their loan. McDowell believes many homeowners also concluded their home was not the rock-solid asset they’d thought, so they felt it unwise to pour more money into it by paying down the mortgage early.

So many just hung in there. By taking on too much debt, and monthly payments so large they could not afford extra payments to bring it down, they left themselves with too much debt too late in the game.

The center says “that 51.6 percent of working-age households were at risk of having a lower standard of living in retirement,” largely because of mortgage debt.

“In recent years, U.S. house prices have started to really improve, to the benefit of homeowners and retirees,” the center says. “But it’s difficult to predict whether the other factor that has reduced retirement preparedness – more older households with big housing debts – was a boom-time phenomenon or represents the new normal.”

But is the situation really as dire as it seems? David Reiss, a professor at Brooklyn Law School in New York City, thinks it may not be.

“According to the National Association of Realtors, the median sales price of an existing home increased from $197,100 in 2013 to $232,200 in October of 2016,” he says. “That is a roughly 15 percent price increase and about $40,000 of additional equity for the owner of the median home.”

Many homeowners who were underwater may not be any longer.

Also, he adds, it’s not necessary to be absolutely debt free at retirement so long as income is large enough to cover expenses and leave a cushion.

“Often, paying off a mortgage gets a retiree where he or she needs to be in terms of that balance, but it is not always necessary,” he says.

The key, he says, is to not be underwater. Once the remaining debt is smaller than the home value, the homeowner is better able to sell. One option is downsizing, selling the current home, then using cash from the sale or a new, smaller mortgage to buy a cheaper home. A less expensive home will also likely have lower property taxes and maintenance costs.

Investing in Mortgage-Backed Securities

photo by https://401kcalculator.org

US News & World Report quoted me in Why Investors Own Private Mortgage-Backed Securities. It opens,

Private-label, or non-agency backed mortgage securities, got a black eye a few years ago when they were blamed for bringing on the financial crisis. But they still exist and can be found in many fixed-income mutual funds and real estate investment trusts.

So who should own them – and who should stay away?

Many experts say they’re safer now and are worthy of a small part of the ordinary investor’s portfolio. Some funds holding non-agency securities yield upward of 10 percent.

“The current landscape is favorable for non-agency securities,” says Jason Callan, head of structured products at Columbia Threadneedle Investments in Minneapolis, pointing to factors that have reduced risks.

“The amount of delinquent borrowers is now at a post-crisis low, U.S. consumers continue to perform quite well from a credit perspective, and risk premiums are very attractive relative to the fundamental outlook for housing and the economy,” he says. “Home prices have appreciated nationwide by 5 to 6 percent over the last three years.”

Mortgage-backed securities are like bonds that give their owners rights to share in interest and principal received from homeowners’ mortgage payments.

The most common are agency-backed securities like Ginnie Maes guaranteed by the Federal Housing Administration, or securities from government-authorized companies like Fannie Mae and Freddie Mac.

The agency securities carry an implicit or explicit guarantee that the promised principal and interest income will be paid even if homeowners default on their loans. Ginnie Mae obligations, for instance, can be made up with federal tax revenues if necessary. Agency securities are considered safe holdings with better yields than alternatives like U.S. Treasurys.

The non-agency securities are issued by financial firms and carry no such guarantee. Trillions of dollars worth were issued in the build up to the financial crisis. Many contained mortgages granted to high-risk homeowners who had no income, poor credit or no home equity. Because risky borrowers are charged higher mortgage rates, private-label mortgage securities appealed to investors seeking higher yields than they could get from other holdings. When housing prices collapsed, a tidal wave of borrower defaults torpedoed the private-label securities, triggering the financial crisis.

Not many private-label securities have been issued in the years since, and they accounted for just 4 percent of mortgage securities issued in 2015, according to Freddie Mac. But those that are created are considered safer than the old ones because today’s borrowers must meet stiffer standards. Also, many of the non-agency securities created a decade or more ago continue to be traded and are viewed as safer because market conditions like home prices have improved.

Investors can buy these securities through bond brokers, but the most common way to participate in this market is with mutual funds or with REITs that own mortgages rather than actual real estate.

Though safer than before, non-agency securities are still risky because, unlike agency-backed securities, they can incur losses if homeowners stop making their payments. This credit risk comes atop the “prepayment” and “interest rate” risks found in agency-backed mortgage securities. Prepayment risk is when interest earnings stop because homeowners have refinanced. Interest rate risk means a security loses value because newer ones offer higher yields, making the older, stingier ones less attractive to investors.

“With non-agencies, you own the credit risk of the underlying mortgages,” Callan says, “whereas with agencies the (payments) are government guaranteed.”

Another risk of non-agency securities: different ones created from the same pool of loans are not necessarily equal. Typically, the pool is sliced into “tranches” like a loaf of bread, with each slice carrying different features. The safest have first dibs on interest and principal earnings, or are the last in the pool to default if payments dry up. In exchange for safety, these pay the least. At the other extreme are tranches that pay the most but are the first to lose out when income stops flowing.

Still, despite the risks, many experts say non-agency securities are safer than they used to be.

“Since the financial crisis, issuers have been much more careful in choosing the collateral that goes into a non-agency MBS, sticking to plain vanilla mortgage products and borrowers with good credit profiles,” says David Reiss, a Brooklyn Law School professor who studies the mortgage market.

“It seems like the Wild West days of the mortgage market in the early 2000s won’t be returning for quite some time because issuers and investors are gun shy after the Subprime Crisis,” Reiss says. “The regulations implemented by Dodd-Frank, such as the qualified residential mortgage rule, also tamp down on excesses in the mortgage markets.”

The State of the Union’s Housing in 2016

photo by Lawrence Jackson

The Joint Center for Housing Studies of Harvard University has released its excellent annual report, The State of the Nation’s Housing for 2016. It finds,

With household growth finally picking up, housing should help boost the economy. Although homeownership rates are still falling, the bottom may be in sight as the lingering effects of the housing crash continue to dissipate. Meanwhile, rental demand is driving the housing recovery, and tight markets have added to already pressing affordability challenges. Local governments are working to develop new revenue sources to expand the affordable housing supply, but without greater federal assistance, these efforts will fall far short of need. (1)

Its specific findings include,

  • nominal home prices were back within 6 percent of their previous peak in early 2016, although still down nearly 20 percent in real terms. The uptick in nominal prices helped to reduce the number of homeowners underwater on their mortgages from 12.1 million at the end of 2011 to 4.3 million at the end of 2015. Delinquency rates also receded, with the share of loans entering foreclosure down sharply as well. (1)
  • The US homeownership rate has tumbled to its lowest level in nearly a half-century. . . . But a closer look at the forces driving this trend suggests that the weakness in homeownership should moderate over the next few years. (2)
  • The rental market continues to drive the housing recovery, with over 36 percent of US households opting to rent in 2015—the largest share since the late 1960s. Indeed, the number of renters increased by 9 million over the past decade, the largest 10-year gain on record. Rental demand has risen across all age groups, income levels, and household types, with large increases among older renters and families with children. (3)

There is a lot more of value in the report, but I will leave it to readers to locate what is relevant to their own interests in the housing industry.

I would be remiss, though, in not reiterating my criticism of this annual report: it fails to adequately disclose who funded it. The acknowledgments page says that principal funding for it comes from the Center’s Policy Advisory Board, but it does not list the members of the board.

Most such reports have greater transparency about funders, but the interested reader of this report would need to search the Center’s website for information about its funders. And there, the reader would see that the board is made up of many representatives of real estate companies including housing finance giants, Fannie Mae and Freddie Mac; national developers, like Hovnanian Enterprises and KB Homes; and major construction suppliers, such as Marvin Windows and Doors and Kohler. Nothing wrong with that, but disclosure of such ties is now to be expected from think tanks and academic centers.  The Joint Center for Housing Studies should follow suit.
