The most important factor when looking for an affordable home is price. No surprise there. But the listing price doesn’t tell you the full story. The seller could have simply picked a number because that’s what they’d like to get, a price that might have nothing to do with reality.

Use the Affordability layer in Trulia Maps to compare listing prices with recent sales prices. Just scroll over your neighborhood of interest to see the median listing price, change your filter, and then scroll over the same area to see the median sales price. There may be a huge price difference between the two, which besides a too-optimistic seller could also reflect a softening market. A once-unaffordable neighborhood, based on listing prices alone, might now be in reach once you see what homes are actually selling for.

Also look at the sales price per square foot, a real eye-opener. You can see exactly how much location affects a home’s price. “If using a price-per-square-foot comparison, the homebuyer must be sure to compare similar-sized properties or allow for the different results based upon the differences in size,” says Greg Stephens, chief appraiser for Metro-West Appraisal Co. in Detroit, MI.

If you already have a neighborhood in mind, take some time to look at the bordering neighborhoods as well. You might find more affordable options that have the same benefits. “As home prices increase within desirable areas, generally speaking, locations on the periphery become in demand,” suggests Michael Kelczewski, a Pennsylvania and Delaware real estate agent.

Pick your neighborhood of interest and note the listing and sales prices. Then pick a bordering neighborhood that costs less to buy into. Compare amenities in Trulia Maps, and you can see where the restaurants, grocery stores, nightclubs, cafes, stores, arts and entertainment areas, spas, and active-life spaces are located.

Don’t rule out up-and-coming neighborhoods. Yes, you’re taking a risk here. “Up-and-coming,” as a description, might turn out to be a tad too hopeful if the neighborhood is really going nowhere. How do you minimize the risk? Look for warning signs. “Distressed areas generally are identified by low sales volumes, elevated value decreases, and poor access to amenities,” says Kelczewski.

If your heart is set on a neighborhood that lets you bike to work and raise urban chickens, you might not be able to get a dreamy, move-in-ready abode with all new upgrades. Instead, target fixer-uppers, or remodels, or teardowns. You might wish to consider a house with “good bones,” as they say, meaning there’s potential in there somewhere. If the house doesn’t even have that, a teardown might be in order.

You can often find fixer-uppers in the foreclosure arena. But beware. “Purchasing an REO/short sale or auction property when the asset is sold ‘as is’ necessitates a network of professionals to understand the condition and to project rehab costs,” offers Kelczewski. “Contractors, electricians, plumbers, even structural engineers may be required in order to adequately analyze a property.”

You’ll also need to devote some time, or sweat equity, to save money when you buy a fixer-upper. “It is important to have a sense of how much work would be needed to get the house in the shape you would want it to be. You would need to get estimates for the work — the final cost will probably be higher than the estimates — and try to determine how long it will take to get permits approved and contractors in the door … [and] it will probably take longer than everyone tells you,” says David Reiss, professor of law at Brooklyn Law School in Brooklyn, NY. “But when you are pulling your hair out because you are cooking dinner in a half-finished kitchen, remember all of the money that you saved when you bought.”
