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

Also, my credit is not the greatest (mid 600's).

As part of the renovation, all of these were remedied however the violations were not cleared as I suspect the renos were done without the full permitting.The purchase agreement had a requirement to clear the violations prior to sale but the Seller and I agreed a fairly substantial seller credit to clear the violations as it was recognized there were risks around the renovation work and potential non compliance with permits that I may have to remedy.

I screen applicants based on set criteria for debt-to-income ratio/credit score, apartments.com is a great tool to manage applications, background checks (the applicants pay for both through the site), i have a google number specifically for the property.  

Buying a primary residence requires the lowest down payment and will get you the lowest available interest rate.If you don’t want to move again then your next best option might be to buy a new or almost new single family home in a fringe area like casa grande for $300k.

Fools investmentThere's a fire- cannot rebuild and investor loses everything; owner ruins his credit; injured tenant sues everyone; everyone broke.Lender calls the loan- everyone losesPaying down a loan does not reduce a payment, this is not a HELOC so that part is not math.There is zero equity to loan on, no one will loan on this.What would buyer have to do to convince a poor elderly person to take this risk- scare them, threaten, lie?

I would never sell a house subject to and put my credit score in the hands of someone else.
