You will now have a huge monthly bill that you must pay.I'm not going to tell you how to think, but looking at mortgage loans and comparing how much you pay in interest is not a beneficial exercise IMO. 

Question: If I have the borrower's sign a deed-in-lieu before closing the loan, what would trigger my ability to exercise it?

@tyler mundy  Are you referring to comping NOIs or are you comping physical property criteria (unit count, finishes)?

If physically seeing and having a copy of the Tenant Credit reports and other Inquiry data is something you must have suggest you include in the Lease Listing Agreement. 

Get a sizeable option fee (make sure the option states it's non-refundable option fee or the like) that you can keep regardless of whether the option is exercised. 

Basically these are exercises for me at the moment as I begin to understand how the numbers work together and against each other.

Minnow and it physically still is... except on paper. 

They are a way for people to own a partial deeded interest in larger physical assets. 

The insured for the property and liability is the owner of the physical property.

@Yana Sha You aren't going to get anything of value out of this exercise without posting the property location.
