Since you're in Florida and the laws are much more fair, I'd be willing to take a chance if his background/credit check came in clean. 

The Fair Market Rent (FMR) on the HUDuser.org website is the Median Rent for the are based on actual rent surveys. 

For primary residences, taxes paid equal 4% of the fair market value of the home times the local millage rate plus any other local district taxes assessed, such as for fire or police, but with a school district tax credit.

It’s priced what would seem like very fair relative to comps in that same neighborhood.

My first duplex Brrr gave me and my wife over $300k equity fairly fast while also allowing us to live at very low cost in an extremely desirable area. 

If you are looking for an alternative, try them.Also, as it should be clear on this thread, appraisers can't be bargained with. 

I hear you on out of state investing, I invest a fair amount in NC where you can still buy houses at 50-60k 2 miles from a Target...lol
