I think I probably would have had better responses if I would have posted the question to finance.yahoo.com  :(

Thank you for the responses!!!

Would a lender simply take the asset back as their own and sell it to balance out or, are the heirs then responsible for the remaining balance?

Very responsive, and smaller family-owned company vibe. 

Thank you guys for the response I realy appriciate it!

@Karen RittenhouseThanks for the response

@Dan Barli thank you for your response.

@Michael Pearse Thank you for the great response.

If you are finding a seller and a buyer for the same property, making them sign an agreement and receiving the commission for that - it's brokering without license, depend on your state, it's a lot of money and sometimes jail time.There are plenty of lawyers on Ytube trying to make it as selling a contract: unless they give their advice in writing to be responsible when you pay $10K+ to the state, I wouldn't hold my breath.you are not selling a contract: you bring to the seller a purchase agreement (as a listing agreement) to buy his property yourself or someone you know....then you find a buyer to buy it for cash.

Finally, use CBRE's 'Multifamily Cap Rate Survey First Half 2018' report to determine what cap rate stabilized properties of similar class are trading for in your area.
