What kind of financial situation is he in. 

See what kind of tenant your “affordable housing” attracts….

Is this neighbor's agreement the only of its kind or are their others that are at or around $2,000/month?

Appreciate the kind words @Robert Burns. 

They might tell you they can't release any info to you without SS number or some kind of authorization or detailed info.Who knows how fast a lender forecloses. 

It hasn’t even been 24 hours since my post and I’ve realized how much I underestimated the kind of help and information I could get on here.

I’m not sure what kind of jobs are in south Boston.

So having some kind of agreement with them that you take profit or get paid however you see fit would be best here. 

Nothing sits on the market for a year that isn't wildly over priced, poorly marketed and/or made difficult to show.Potential buyers have probably tried to see the place and are being denied or some sort of nonsense to make them not want to make an offer.I bet the realtor will have some interesting info to share - or if they won't say anything to you bc their agreement is with your partner kindly share with them that the houses are in your name and the listing's need canceled immediately unless they start cooperating.Have you laywerd up yet?

@Colleen F.The problem is that it is difficult to define what is necessary when you run into this kind of situation.
