If you want to remain friendly with the neighbor, I'd suggest checking out his unit and then running water all over the shower walls and putting some water on the floor around the shower/tub "pan" and around the toilet.

(I just don't see how a pitbull could offer more emotional support than a poodle or spaniel.)I'd encourage you to google HUD guidelines for Emotional Support Animals.

If family lives in the main home and friends stay for free in the garage, the property remains a primary residence, but there’s no rental income or tax benefits.

All this fancy mumbo fha guideline gumbo means is that your projected market rents assuming all units, if it were rented Times 75% need to be greater than what your monthly payment is  (PITIA = principal/interest/taxes/insurance/assessments monthly), other wise FHA will not lend at that loan amount so common solutions to this when rents are too low in your local market are to put more money down payment which defeats the whole purpose of low 3.5% down FHA doesnt it?

I always suggest starting with friends and family and even ask them if they know anyone who might be interested.

Meaning are there states that are less friendly to lender / note owners?

@James Wise  Jim being a close personal Friend of Clayton and Natalie you have any intel on this ???
