How do I properly get proof of the alimony she will receive AND how do I protect myself from her either not paying or getting her alimony to pay?

To this day I have not been able to get any proof of how the property looks, any tenant info, or anything related.

What proof do they have that they paid for the last two months' rent?

This is the same company that says STR are recession proof.

The glass area of the window(s) must be 8% of the floor area. 

When buying an apartment building, it's reasonable for the buyer to ask the seller for copies of leases and proof that the rent is coming in, and the lender will likely ask for that same paperwork too (since that's what's paying the mortgage, not the buyer's personal W2 income, ha).

While there are certainly cases where they can make great money, in general your best recession-proof best is likely a more "average" home.

1st of all corporations own less than 2% of single family homes, they have actually reduced thier share of buying recently, now investors continue to buy up properties, it’s just more mom & pop types, all that said the housing market is in an extremely strange place, I could make strong arguments for prices pulling back, reaccelarting, or being basically flat, the biggest thing I’d advise is looking at you payment, comparing that to what would pay in rent, figuring out how long you plan to be the house and making an decision based on that, generally in that under 400k price point, breakeven for buying a property seems to about 3-5 years if you plan to stay in the house longer than that, bite the bullet & buy, if not rent.  

For proof, try to find a residential syndication that does not have an appreciation play.  

Their is no such thing as a bulletproof plan to avoid personal liability, but you can get close.
