Plenty of people want a place a short walk from dog beach with an enclosed private yard for their dog and are willing to pay for it. I am having second thoughts on saying 550,000 is a good price given that the listing is now a week old and still has no interior photos.
OB has momentum and at least relative value.
I am a landlord and resident here too. Must be nice to have properties purchased 20+ years ago at 1/4 or less of market price, and still taxed that way too. My residence purchased as a short sale in 2011 is at least 40% below market price, so I have that!
