As a Realtor, I suggest that prior to bidding on the property, make sure what deed restrictions apply. If the restrictions are from the Council on Affordable Housing, there are different rules for municipal and not for profit sponsored units, and for owner occupied and rental. If it was built quite some time ago, do the restrictions still apply?
The rules and restrictions can be found in this link...
My understanding is that with each affordable housing unit sale, along with the deed a 'Declaration Of Covenants, Conditions And Restrictions Implementing Affordable Housing Controls On State Regulated Property' is filed as an attachment. You should check that.
There are many attorneys that work in the field of affordable housing, they would be your best bet for a difinitive answer to this question. You could also contact Melissa Orsen at 609-292-0921. She's Deputy Director and Counsel to the Affordable Housing Council.

Oh! Had you emailed me? I hadn't realized. I don't see one in there, but it's perhaps possible that it ended up in my spam folder and deleted. This happens from time to time - my spam software has a mind of its own. Please email or call me and I'll catch you up. The story is pretty interesting.
