The electric company plugged in the new meter and drove off, the fire started shortly there after (no interior inspection occurs and the tenant doesn't have to be home).The investigation identified the kitchen stove wiring as the source of the fire (I personally think the stove may have been in use at the time of shut-off and was left on so the sudden restoration of power caused arcing), wiring was not ruled out so an electrical inspection was required by the city and they concluded all wiring in the unit (romex) would have to be replaced due to ambient heat exposure. 

I'm waiting on his credit report, but are there other things or areas that I should investigate on a cash-only applicant?  

@Michael Haas  out of curiosity what does it usually take to legalize an existing unit  (lets say it was basically well constructed basement ADU,  but built a decade or more ago without any permits/etc I don't have any such situation so just a hypothetical question,   though I do have some extra storerooms at one of my properties that would be best converted to a studio unit ; but when I investigated this with the local municipality they basically wanted me to upgrade the entire building to current code standards in order to be able to finish out that space as a 5th unit.   

Once I have a short list of interesting markets, I'd be more inclined to investigate those markets via your reports.Are you making that sort of info available?

I have been investigating about 25 possible properties, half of those are REO's.

Purchase and Sale Agreement, Sales Contract.Lender has no knowledge of and is unwilling to investigate into latent defects, is selling as-is with some systems not working?

As I am from out of town I was hoping some people more familiar with Orlando could recommend some specific regions that are worth investigating. 

It may be worth investigating why that is and use those whys accordingly when searching for the alternatives.Good luck! 

Investigate the deal, and see where it brings you.

I trusted the seller, and never bothered to investigate it thoroughly or due my own due diligence on the matter.
