I hope you can find your way out of such a hole soon. 

Its almost like a loop hole.

If that money is somehow burning a hole in your pocket then you can set up a small marketing campaign and use say $500 - $600 per month on letters or post cards for distressed properties then wholesale them.

The foundations are often stone and drainage not properly maintained so it's not uncommon to have foundation issues or failures.From a end user standpoint, there are quite a few 4 plexes built in the 50s and 60s that are around the 4,000 square foot mark with 2 up and 2 down.

My best advice is to get the sticky screen patches for small holes on screens it saves a ton of time and headache.

Not to mention it's no the worst thing in the world if Uncle Eddie can drive by the property every once in a while and make sure there isn't a gaping hole in the roof.You can, of course, repeat this process with any of the popular geographies:  Cleveland, Akron, Memphis, etc. but you're not going to have someone local there (with no commission to be earned) to tell you a good vs. bad area.  

Other areas SFHs are going to be a money hole. 

Putting up shutters, waiting in line at 4am to hopefully get plywood, dealing with the aftermath of power outages, having to cut down three palms, two olive trees, one crepe myrtle, three mangos, one strangler fig, all mature trees on various properties, one branch fell on roof and punched a hole collapsed the ceiling of a unit, one branch as big as a power pole fell on another roof with one end resting on a live high voltage power drop, over 200 linear feet of fallen fences...all the damages and none of it covered by insurance as our windstorm coverage is around 5% deductable.

I've found a foreclosure that needs a lot of work from mold to rotting holes in the subfloor to a half finished roof thrown on by the bank.

Congratulations and welcome to the real estate rabbit hole.
