Are you looking for protection for the current arrangement or are you looking for a new arrangement?

@Robert FowlerAs with any real estate agreement, Seller financing arrangements should be detailed in writing to ensure that both buyers and sellers understand their responsibilities under the contract.

And for me, the biggest lesson to takeaway is if someone is proposing an unusual arrangement, there is usually a reason why and to be wary.

This is why Gmail is free--they index your emails, note that you mentioned the word "flowers" 47 times last week, and send targeted ads for "FTD Flowers" to you on the web.

A few months in now, my downstair neighbor mentioned that the previous owner made an arrangement with them and said they can do a sound test inside the unit.

Depending on how you will arrange the agreement.

That arrangement sounds far-fetched!

But because it sounds like the whole arrangement was off the books with an unlicensed guy it gets kinda fuzzy.

@Janille JacksonHUD guidelines allow borrowers to do their own work on a 203k (called a self-help arrangement). 

After 12 months on the "All Star" list, they also receive an appreciation card and a gift, such as a flower basket, door mat, gift certificate, etc.
