I think generally speaking, parking will get you much more money for your home on resale. Many people I know, myself included since I work in VA, limit DC home searches to homes that have off street parking. For us it was a dealbreaker, and we were willing to pay more to ensure we had a place with a dedicated parking spot. We knew people who purchased in places with tons of street parking, only to discover 5 years down the line that due to the DC boom there were no longer tons of street spaces due to influx of new residents with cars as well as new businesses nearby. They regretted not ensuring they purchased a place with parking from the start.
