The only PITIA paid from personal account is for a personal residence.

My personal return is fairly complicated with Trusts, partnerships, W-2s, and several K1s.

Recently she changed her will and named us as personal representatives and is leaving us her property when she passes(crazy I know).

The notice of a tax sale may not get to the right person to pay it off. 

Build a home and then purchase that product with a personal conventional or FHA loan? 

This is an extremely important point, because if there is no clear rules defined by each person, then it can be confusing and lead to anger or resentment between partners.

o Commercial loan, sort of - they are 30-year fixed DSCR loans with private national lenders.o We close in an entity/LLC 99% of the time - very rarely do we receive a request to close in someone's personal name.

And the bank will need a contact person for security reasons.  

If  your rule is not to rent to anyone with a prior eviction, this person would fall under that rule.  

It effects every aspect of the property and performance- the type of loans and insurance you need will change if you don't hold the property in your personal name.
