All of a sudden it turned out to be an inheritance/gifted money/whatever.

After speaking with a bank, I have also learned that "gift money" as they call it cannot be used as a down payment to obtain financing for an investment.

You could also cut them a "thank you" check or send them a gift basket if you still feel like doing more.

They limit the amount you can take out and also vet out where the money came from (for instance if you received a gift or anything like that). 

John,I would try to find out who the manager was to send them a thank you gift.

Got a big ugly yellow Motorhome to offer as a placeholder (or lovely parting gift, like on TV game shows)?

(I was able to use gifted funds so it all worked out.) 

He talked to a lender (he went through them to buy his last home a few months ago) and this is what he said:"Because you would be selling your home to a family member you can do something called a “Gift of Equity”.

If he accepts such terms it would basically a partial gift as he could do far better return with less risk.  

The difference in what I needed to have saved and prepared for the purchased changed by several thousand dollars, and a lot don't allow "gifts" or unsecured LOCs to help --- so like I said... be very clear and ask a lot of questions, and be prepared for hurdles along the way.
