Historic homes are often considered a treasure. But figuring out where they’re located can be a difficult task for homebuyers.

A recent study by the home buyer site, Sundae, found the US cities with the oldest homes. Although the US is less than 300 years old, Sundae found that the homes in some cities boast median ages that date back nearly a century.

To find the median year of home construction and the median overall age of the homes in each city, Sundae analysed public tax assessor records and real estate listing data for residential houses in the largest 660 markets. Note that Sundae considers Brooklyn and Jamaica within New York City as separate cities because of their large populations and significant statistical sample size.

Keep reading for a look at the 15 US cities with the oldest homes, ranked from lowest to highest median year of of home construction.
