DC is one of the cities I was not able to do CMA based on square feet (or public data). It varies a lot based on what’s happening downstairs (if there is). And how crowded the streets are, there are some streets so crowded that it is quite a turn off for future tenants too. And also where it is located (view of cemetery / where in west side of skyline blvd).
One thing I know was last year, there are one or two houses that are being sold at 1M & 1.05M where majority were in 825K - 900K range, now that range move up about 100K today and where one or two houses being sold around 1.15M & 1.2M like that 1.17M house, I have no idea why that one sold that much other than I know that it was arrogant Listing Agent.
