None of my clients do the "co-GP", its a very thin facade...light on substance usually will land both parties under federal trouble...

If an applicant doesn’t have a SSN I would not rent to the applying party.

Invasion of privacy, unclean and rude house members, maybe if they do drugs or smoke or are party animals, unwanted friends of theirs visiting at odd hours, clashes of personality

Appreciation for the most part is non-existent unless you force it w/ improvements.  

I always thought that the assumption of mortgage meant that they essentially replace me as the initial party paying off the mortgage and now they pay the monthly payments and have the title.

What would be the best option for both parties?

Both parties are deceased with no known heirs and unfortunately, we do not have the necessary information to get a copy of the death certificates.

I guess I am late to the party.. anyone else work with Chris on a "positive solution" yet? 

This strategy involves having a third-party entity hold the replacement property while you complete the sale of your relinquished property.

In the end I just want it to be fair for both parties.
