There is nothing about how long you need to occupy the property for.So unless our lender puts a demand on us I see no problems legally in occupying each property for any amount of time to fulfill the requirement, then rinse and repeating this process up to our full entitlements, so long as the lender is willing to keep giving us loans.

However, you don't mention if this was added to their rental agreements or how this was documented. 3.

If a guest stays for one week in July, the owner can't legally rent to another guest until August and must leave their unit vacant for three weeks.

Can we obtain a special form or document to show the loss?   

I consulted with a real estate lawyer a few times this year who said it's very hard to sue for negligence and they advised against taking legal action, especially since the property manager at least followed through on the eviction and repairs.I've now asked the property management company to apply a $4k credit for all the challenges I've had working with them.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

I have done extensive research in the risks, how to structure such deals to mitigate those risks as effectively as possible, and legal considerations of each strategy. 

Your goals will define the route you take on this but building a list for buyers/investors is a time-intensive activity and the list is a living and breathing document.

Quote from @Aaron Zimmerman: I would look for other ways to legally reduce income such as cost segregation studies.

And not just in our contract the title company sends a mutual release document of their own that both parties have to sign..
