Median home value: $85,900
Share of homes worth less than $100,000: 60.3 percent
Median home size: 5 rooms
Median household income: $35,636
Five-year population change: 3.9 percent
Many homes on this list are located in areas that "have had slower-than-typical population growth in recent years," the report says. Cleveland, Detroit and Buffalo, for example, "have had declining populations for decades." That reduced demand could explain why home values in these areas are lower.
On a national scale, after all, housing is getting more expensive: U.S. home values have gone up nearly 8 percent over the past year, according to Zillow, and are predicted to rise over 6 percent within the next year.
So if you do find a home for sale that seems like a steal, approach with caution.
"Bargains definitely exist, but buyers should go in with their eyes open," says Realtor.com chief economist Danielle Hale. In some areas, she explains, "$100,000 can buy a pretty decent home that maybe needs a little bit of updating." In other places, however, "it might be a home that needs an awful lot of work and might be in not-yet-up-and-coming neighborhoods."
