@Jeb Brilliant Were you able to get taken care of? 

I’m trying to buy 2 family house that is Currently a old day care center and the CofO is listed as Community Facility so the process to change back over here in new york could taKE up to 6 months to year plus Architect is giving me a Estimate of 100k.

Remember, youre letting someone into your inner circle to teach you and to take care of you.

Some care about "doing the right thing" for the deceased owners and others see no benefit. 

If that is the case, then mortgage interest on a note is passive and not subject to UBIT.UBIT applies when a tax-exempt entity engages in a trade or business on a regular or repeated basis.Passive income not subject to UBIT includes royalties, dividends, interest, rent from real property and gains on the sale of an asset that has been held to produce such passive income.Trade or business subject to UBIT generally consists of services or buy/sell transactions. 

If he refuses to pay anything, give him the deposit and move on because he's cared for the home and is giving it back to help you sell it, so that has some value.

Again, take my word as that of an amateur as well, but that's how i would approach it. 

Be careful if you offer.

I'd actually consult the advice of an attorney. 

If anyone would care to elaborate.
