You don't mention anything about the exterior of the house...does it have good curb appeal? Eventhough mechanicals are huge, many people still look at the cosmetics of the house. Do you have it listed on different websites like craig's list and have an expanded listing on Realtor.com? I find that having as many pictures as you can when listing a property is key. Good luck!!!
If you haven't done so already you might want to get yourself a membership over at http://www.loopnet.com/ and post a listing there.
I hope that helps.
BTW...if it's in Black Rock, contact me.
