Homes are getting contracts in days, not many weeks or months like you may think. The market has been heating up and homes that are in nice repair are moving. The average days on market for townhomes listed within the past 30 days as of this writing went under contract in an average of 12 days. (Based on a geographical map search that covers popular south west DC suburbs in Northern Virginia.) See the map area with a link to active listings here.
