Housing Stability in the Mamdani Administration

By Phillip Capper, Wellington, NZ – 143rd. St., Bronx, NY, 2/08, CC BY 2.0

I am looking forward to the discussion tonight on Housing Stability in the Mamdani Administration, hosted by the Urban Design Forum. While it is sold out, we will be discussing “what a potential rent freeze may look like under the Mamdani administration” and I am sure there will be some good reporting on this topic over the coming weeks and months. The Forum writes,

As living costs continue to rise, Mayor-elect Mamdani has proposed freezing rents on stabilized apartments as a way to support tenants and protect housing stability. At the same time, critics warn that such measures could make it harder for building owners—particularly those managing older buildings with thin margins—to maintain safe, livable homes.

We’ll begin with an overview presentation by Mark Willis of the Furman Center, followed by a panel with Oksana Mironova, Emily KurtzDavid Reiss, and Thomas Yuon how the next administration can promote tenant stability and preserve affordable housing.

What strategies can preserve deep affordability while ensuring stabilized buildings remain financially sustainable?

Understanding NYC’s Rent-Stabilized Housing Stock

I will be moderating an NYU Furman Center Policy Breakfast on NYC’s Rent-Stabilized Housing: Understanding Different Segments of the Stock and Why It Matters on November 19th. The link to register is here.

Nearly one million apartments in New York City are rent-stabilized. In 2023, the median rent among rent-stabilized tenants was about $1,500, compared with $2,000 for market-rate renters. These units play a central role in maintaining housing affordability across the city, yet they are often discussed as a single, uniform category.

Our policy breakfast will explore the diversity among buildings with rent-stabilized units, spanning older pre-1974 buildings and newer developments regulated because they received public financing or property tax reductions. Panelists will discuss how these differences shape the challenges and policy considerations facing the rent-stabilized housing stock today. The session aims to deepen understanding of the current landscape and to ground debate on what tailored interventions may be needed to preserve the affordability and quality of this essential part of New York City’s housing supply.

Fannie, Freddie and Trump

Central Banking quoted me in Fannie, Freddie . . . and Donald. It reads, in part,

IIn a client note on May 13, investment management firm Pimco said any privatisation of Fannie and Freddie would be a solution in search of a problem.

“If the GSEs are released but the government remains accountable to come to their rescue, wouldn’t taxpayers ultimately be the biggest loser, once again, by seeing GSE gains privatised but losses socialised?” it said, adding: “Don’t fix what’s not broken.”

David Reiss, professor at Cornell Law School, says Pimco’s view reflects the fact that the mortgage market has been functioning “pretty smoothly” since Fannie and Freddie were nationalised. According to this viewpoint, there is “no need to release them from conservatorship”.

However, Reiss says he does not like to see so much power and influence concentrated in the GSEs, and he believes the private sector would do a better job of evaluating credit risk.

“Some people – mostly investors in Fannie and Freddie securities – think [privatisation] is the right thing to do because the conservatorships were supposed to be temporary and the companies should be returned to private control and investors should be able to get some kind of return on their investments,” he says.

Reiss adds that some members of the Trump administration think privatisation would generate hundreds of billions of dollars in revenue that could be used to help pay down the national debt, offset tax cuts and seed a sovereign wealth fund.

Joe Tracy, senior fellow with think-tank the American Enterprise Institute and a former official with the Federal Reserve banks of New York and Dallas, agrees with Reiss. “The problem is that they are in conservatorship limbo, so the government has effectively nationalised a large segment of mortgage finance,” he says. “This should be carried out by the private sector.”

    *     *     *

Lawrence White, professor at New York University and co-author of Guaranteed to Fail: Fannie Mae, Freddie Mac and the Debacle of Mortgage Finance, says the GSEs are unlikely to become boring unless they are broken down. He believes that if Fannie and Freddie are privatised in their current form, each enterprise will be likely to pose a systemic risk from a financial stability perspective.

“The implication is that their regulator, the Federal Housing Finance Agency [FHFAI, will need to have strong powers of examination and supervision and will need to impose substantial, risk-adjusted capital requirements,” he says.

“It is unclear whether there will be implications for the Fed as lender of last resort, since the Fed’s lending function is currently limited to banks.”

Reiss agrees that the two lenders are systemically important. If they “had to significantly scale back their lending, it would likely cause a crisis in the financial markets”, he says. “If that crisis were not quickly addressed it would cause a crisis in the real economy as well, freezing up credit for new construction and resales.”

Given that the two GSEs issue more than 70% of the outstanding $9 trillion of mortgage-backed securities in the US and, if privatised, would be two of the country’s largest publicly traded companies, the financial stability risks are clear, he says.

Reiss adds that if the privatisations were poorly planned, and if this were priced in by the markets, it would lead to “higher mortgage rates, with all of the knock-on effects that would have”. This, he says, would “increase the magnitude of a financial crisis if the two companies were to report poor financial results down the line”

Reiss’s interpretation of the Fed’s role is different to that of White, and he believes history may end up repeating itself. He says that although the FHFA is Fannie and Freddie’s primary regulator, the Housing and Economic Recovery Act of 2008 requires the Fed to be consulted about any federal government processes related to the companies.

“The Fed may also co-ordinate with other parts of the federal government in responding to a financial crisis, such as purchasing Fannie and Freddie securities, as they did during the financial crisis of 2007-08,” he says. “One could well imagine the Fed playing a similar role in future crises involving Fannie and Freddie.

Micro Apartments and The Housing Crisis

The NYU Furman Center has posted 21st Century SROs: Can Small Housing Units Help Meet the Need for Affordable Housing in New York City? The policy brief opens,

Throughout much of the last century, single-room occupancy (SRO) housing was a commonly available type of low-rent housing in New York City, providing housing to people newly arrived in the city, low-income single New Yorkers, and people needing somewhere to live during life transitions. SRO units typically consisted of a private room with access to full bathroom and kitchen facilities that a renter shared with other building occupants. As the city fell onto hard times, so did SRO housing. During the second half of the last century, many SROs came to serve as housing of last resort, and policymakers enacted laws limiting their construction and discouraging the operation of SRO units. Many SROs were converted to other forms of housing, resulting in the loss of thousands of low-rent units in the city.

New research and analysis from the NYU Furman Center addresses the question of whether small housing units (self-contained micro units and efficiency units with shared facilities) can and should help meet the housing need previously served by SROs. In this policy brief, we present a summary of the paper, 21st Century SROs: Can Small Housing Units Help Meet the Need for Affordable Housing in New York City? We provide an overview of the potential demand for smaller, cheaper units, discuss the economics of building small units, analyze the main barriers to the creation of small units that exist in New York City, and suggest possible reforms that New York City can make to address these barriers. (1)

The policy brief makes a series of recommendations, including

  • reducing density limitations for micro units near transit hubs
  • permitting mixed-income and market-rate efficiency units
  • creating a government small unit program to promote the construction of micro apartments

There is no doubt that the lack of supply is a key driver of the affordable housing crisis across the country. Small units should be part of the response to that crisis, not just in New York City but in all high-cost cities.

Eminent Domain and Trump’s Wall

Sucamore Gap on Hadrian’s Wall

Mashable quoted me in Sorry, Cards Against Humanity Can’t Stop Trump’s Wall. It opens,

As much as we may want to believe it, a card game company probably can’t save our country.

This week, owners of the irreverent (and kind of obnoxious, imo) Cards Against Humanity game unveiled their annual PR stunt and it has higher aspirations than last year’s pointless hole.

As part of the Cards Against Humanity Saves America campaign, it announced the purchase of “acres of land” on the U.S.-Mexico border and promised not to build a wall on it.

Going further, the company said that it had retained the services of legal representation specializing in property rights, “to make it as time-consuming and expensive as possible for the wall to get built.”

Sounds good, right? Guess there won’t be a wall!

Not so fast, patriots.

The government has a big ace up its sleeve when it comes to taking land from property owners. It’s called “eminent domain” and it’s right there in the constitution’s Fifth Amendment, below the part that people always talk about on lawyer shows. The Fifth Amendment states the government can’t take “private property be taken for public use, without just compensation.”

But it can still take land for public use, and it almost always does.

Government is mightier than the card game

The several law professors we talked to all came to the same forgone conclusion: the government will ultimately take that land from Cards Against Humanity.

“The power of eminent domain is considered to be a fundamental power of any government to use,” Professor of Law David Reiss at Brooklyn Law school said. And in this case, given the limited facts that were available to him, “ultimately the government would succeed.”

Over the past several decades, the judicial definition of eminent domain has expanded broadly. Historically, governmental use of eminent domain would fall under the umbrella of public use by using the acquired land to build a road or build a hospital. That’s changed in recent years, as the blanket phrase of “public use” has been used in eminent domain cases to include razing blighted urban areas or if the land could be seen as encouraging economic development.

Richard Epstein, Professor of Law at NYU, emphatically agreed that Cards Against Humanity would not stand much of a chance. Legally speaking, he saw, “the wall [will be seen] as a public good. There’s nothing you could do to resist them taking the land.”

Lynn E. Blais, Real Property Law Professor at the University of Texas at Austin, also thought that the government would easily win, but acknowledged how Cards Against Humanity could make an impact.

“They can’t stop the border wall for sure,” Blais said. Legally speaking, “it’s clearly for public use [but] they can challenge the process at every step if they want. That could take a long long time.”

And just as the company mentions in its announcement, it hopes to get in the way and meddle up Trump’s plans to build a wall, at least in that one plot of land it purchased. That delay tactic might prove exceptionally effective.

“They may not be looking to stop it, but merely to delay it. Delay can be very powerful. Sometimes delay can be as effective as winning the case,” Reiss said. “With enough money, it can be delayed for years.”

Did CAH fall down at the starting line? 

A few of the legal experts we talked to were adamant that Cards Against Humanity, in openly alluding to the fact that they hoped to make the wall construction “as time-consuming and expensive as possible,” invariably hurt their chances to gain favor with a judge. Basically, in flipping Trump off through a land buy, they exposed their bias and they might not receive a full case because of it.

“I wonder if they shot themselves in the foot if they admitted this was a delay tactic. Some judges might few that negatively,” Reiss said. “Judges wouldn’t look kindly on admitting delay.”

Epstein was very certain that the company’s promotion would hurt their chances of winning any case the federal government might bring against it.

“They are tacitly admitting that the goal is to block the president,” he said. “It’s one one of the dumber ideas I’ve heard of.”

He was certain that it would only invalidate any defense Cards Against Humanity tried to bring up, seeing as how the company already showed its actual intent. Still, he thought of it as a sign of the times, saying, “One of the consequences from the president acting like a crackpot means you get crackpot solutions.”

Blaise, however, believed the opposite side of this argument, and thought that land owners can do whatever they damn well please.

I don’t think it matters why you don’t want the government to take your land. As a property owner, you get to be as irrational as you want,” she said.

So you’re saying there’s a public use chance…

Even though a prospective case doesn’t look too promising for Cards Against Humanity, it still has avenues it can take to launch a defense of their new land. According to the legal experts we talked to, the most promising defense would be on whether the wall is really for public use. This is given that “public use” in the Fifth Amendment is not terribly defined and that arguments could readily be made that a border wall with Mexico might be more harmful than good.

“Public use is now often an incredibly broad term,” Reiss said. And, should the case go to federal court, the government’s potential case would invoke border security or immigration policy, which Reiss thought a judge would probably find compelling evidence.

Regulatory Approaches to Airbnb

Peter Coles et al. have posted Airbnb Usage Across New York City Neighborhoods: Geographic Patterns and Regulatory Implications to SSRN. Two of the co-authors are affiliated to Airbnb and the other three are affiliated to NYU. The paper states that “No consulting fees, research grants or other payments have been made by Airbnb to the NYU authors . . .” (1) The abstract reads,

This paper offers new empirical evidence about actual Airbnb usage patterns and how they vary across neighborhoods in New York City. We combine unique, census-tract level data from Airbnb with neighborhood asking rent data from Zillow and administrative, census, and social media data on neighborhoods. We find that as usage has grown over time, Airbnb listings have become more geographically dispersed, although centrality remains an important predictor of listing location. Neighborhoods with more modest median household incomes have also grown in popularity, and disproportionately feature “private room” listings (compared to “entire home” listings). We find that compared to long-term rentals, short-term rentals do not appear to be as profitable as many assume, and they have become relatively less profitable over our time period. Additionally, short-term rentals appear most profitable relative to long-term rentals in outlying, middle-income neighborhoods. Our findings contribute to an ongoing regulatory conversation catalyzed by the rapid growth in the short-term rental market, and we conclude by bringing an economic lens to varying approaches proposed to target and address externalities that may arise in this market.

I found the review alternative regulatory approaches to be particularly helpful:

City leaders around the world have adopted a wide range of approaches. We conclude by reviewing these alternative regulatory responses. We consider both citywide as well as neighborhood-specific responses, like those recently enacted in Portland, Maine or in New Orleans. A promising approach from an economic perspective is to impose fees that vary with intensity of usage. For instance, in Portland, Maine, short-term rental host fees increase with the number of units a given host seeks to register, and a recent bill from Representatives in the Commonwealth of Massachusetts (H.3454) propose taxes that vary with the intensity of usage of individual units. Such varying fees may help discourage conversions of long-term rentals to short-term rentals and better internalize externalities that might rise with greater use. That said, overly-customized approaches may be difficult to administer. Regulatory complexity itself should also be a criterion in choosing policy responses. (2-3, citations omitted)

We are still a long ways off from knowing how the short-term rental market will be regulated once it fully matures, so work like this helps us see where we are so far.

Rental Housing Landscape

A Row of Tenements, by Robert Spencer (1915)

NYU’s Furman Center released its 2017 National Rental Housing Landscape. My two takeaways are that, compared to the years before the financial crisis, (1) many tenants remain rent burdened and (2) higher income households are renting more. These takeaways have a lot of consequences for housing policymakers. We should keep these developments in mind as we debate tax reform proposals regarding the mortgage interest deduction and the deduction of property taxes. When it comes to housing, who should the tax code be helping more — homeowners or renters?

The Executive Summary of the report reads,

This study examines rental housing trends from 2006 to 2015 in the 53 metropolitan areas of the U.S. that had populations of over one million in 2015 (“metros”), with a particular focus on the economic recovery period beginning in 2012.

Median rents grew faster than inflation in virtually every metro between 2012 and 2015, especially in already high rent metros.

Despite rising rents, the share of renters spending more than 30 percent of their income on rent (defined as rent burdened households) fell slightly between 2012 and 2015, as did the share spending more than 50 percent (defined as severely rent burdened households). Still, these shares were higher in 2015 than in 2006, and far higher than in earlier decades.

The number and share of renters has increased considerably since 2006 and continued to rise in virtually every metro from 2012 to 2015. Within that period, the increase in renter share was relatively larger for high socioeconomic status households. That said, the typical renter household still has lower income and less educational attainment than the typical non-renter household.

Following years of decline during the Great Recession, the real median income of renters grew between 2012 and 2015, but this was primarily driven by the larger numbers of higher income households that are renting and the increasing incomes of renter households with at least one member holding a bachelor’s degree or higher. The real median income of renter households with members with just a high school degree or some college grew more modestly and remained below 2006 levels in 2015.

Thus, the recent decline in the share of rent burdened households should be cautiously interpreted. The income of the typical renter household increased as the economy recovered, but part of this increase came from a change in the composition of the renter population as more high socioeconomic status households chose to rent their homes.

For almost every metro, the median rent in 2015 for units that had been on the market within the previous year was higher than that for other units, suggesting that renters would likely face a rent hike if they moved. The share of recently available rental units that were affordable to households earning their metro’s median income fell between 2012 and 2015. And in 2015, only a small share of recently available rental units were affordable to households earning half of their metro’s median income. (3, footnote omitted)
