It’s quickly becoming more expensive to live in D.C. and its inner suburbs, and that’s especially true for locations near public transit.

Commuting preferences aside, this can make good financial sense for some, as not owning a car can substantially decrease a household’s overall costs. Although many people of varying incomes in the city are concerned about being able to afford the escalating housing costs, D.C. was also ranked by one group as more affordable than other U.S. cities when transportation costs were also considered.

Which Metro-accessible neighborhoods are the priciest and which less so? Using data on some 20,000 one-bedroom apartments that were listed for rent in the month of September, the apartment search site RadPad tried to determine where the highest and lowest rents are within a half-mile radius of Metro stations.

Some takeaways:

— Foggy Bottom is the most expensive place to rent an apartment, at $2,723 a month. No doubt this is driven in part by some rec0rd-breaking rents at Residences on the Avenue, the new apartment complex with a Whole Foods across from the Metro station. Those units have become highly popular with George Washington students and, cynics would say, their well-heeled parents.

— New apartments cost more. Units in Mount Vernon Square, where there is a bevy of new luxury buildings, average $2,402 per month, nearly the price of places in Dupont Circle, which has many older buildings.

— Some Green Line neighborhoods are now pricier than those along the Red Line in Northwest. U Street rents average more than $200 per month more expensive than Woodley Park. Even Columbia Heights costs more than Woodley Park. This was unthinkable a decade ago.

— Does Anacostia really cost that much? More than McLean? More than Navy Yard? $300 a month more than Crystal City? The folks at RadPad said that the number could be skewed because there were only 20 listings in the area and those included some in the Navy Yard area.

There are other caveats, of course: The data does not take into account bus lines or rents for apartments that are bigger or smaller than one-bedrooms. And not every Metro station is represented. But the increasing value of transit, even in neighborhoods once considered less desirable, is becoming increasingly apparent.
