What is the best all-in-one property management software that includes tenant screening, applications, rent collection, maintenance requests, etc.? 

I recently put my Pensacola house up for rent on Zillow, and I received an email from a company that specializes in temporarily relocating families displaced by damages to their home.

Exactly.Accountants more or less have a consensus that for landlords, your business starts when your first property is ready and available for rent.

Cash flow requires short term, mid term, or rent by the room strategies as I see it. 

Your strategy was (is) to make no payments on the mortgage and live there with no monthly mortgage, tax or rent expense until a lien holder foreclosed, which you believe you’re protected against because the borrower on the existing note is in active military service?  

Given your situation, I think the best thing to do is 1) work on improving your credit and 2) look to house hack, preferably a duplex or fourplex where you live one unit and rent out the others.

In tenant LL terms, making it harder to evict marginal tenants result in rent increases.  

Depending on how well the property is run and the rents. 

The rent amount.
