This is my first post and I’ve been diving into real estate investing for a few weeks now; just reading, listening, and watching REI information non-stop.

Non-super conforming mortgages remain unaffected.You can verify this with section 4501.10 of the Freddie Mac "Single-Family Seller/Servicer Guide", updated just a few weeks ago: Feb 6th 2019. 

A little move in basket with some of the following :  assorted felt furniture protectors for the wood floor, a sponge, cleaner for a glass top stove if there is one, a small bottle of hand soap,  a couple of packets of dishwasher detergent, maybe a dishtowel, and a roll of paper towels,  windex or such. 

This eliminates double bookings and allows the cleaners to be aware of last minute bookings without a source constantly monitoring and updating. 

Offer contingency rests heavily on condition of the park and the interiors of the abandoned homes...and assessing whether these homes can be repaired—and if so, will it cost me an arm and a leg to repair 1 or 5 or 10 of them.Obviously, this is a distressed, non-performing MHP, which has a ton of risk. 

@Randy SmithYes but the financing must be non-recourse (as well as subject to the Solo 401k real estate rules that apply generally).

Unless they are non recourse loans, then by all means borrow away.

My tax advisor stated Box 1 "Rents" and the church tax advisor states Box 7 "Non-Employee Compensation" since it's not actual rent for the church but considered a donation to them.

Keep it professional and short and non-negotiable.

There are ways around that for example if you used seller financing then you would be signing a non recourse loan.
