He reported that it fell over.

The tenant living there offered to buy the home, but mortgage application just fell through due to bad credit. 

Because as I happened to browse bigger pockets, I found the following post from you: I am an out of state investor who fell for the marketing hype put out by a Mempis wholesaler about what a great place Memphis was for rental cash flow.

Are you telling me that they now fell into a secret file that is still on my confidential/flagged file??

One of them was so rotted that it fell apart.  

Had them tunnel 23' under the house to fix the fitting - turned out the fitting was never glued during original construction and just fell apart after soil settled. 

@Sean CassidyHe tried moving already - but it fell through. 

That DID resonate with me - it's just the weekly e-mail thing was another chore that fell by the wayside.

Sounds like the current tenant had a better place lined up and it fell through.

Roof mounted MIGHT sound like big humming noise on the entire top floor whenever the units are on.No way to tell ahead of time.Cages on ground units, keep inquisitive hands off the units.In some areas the roofs are alive (and dead) with people.I know a man that was evicting renters (w/o court approval, self-help tough guy eviction) for being on the roof, he went up there himself when he caught them up there, they left and he fell off and died.Next owner same building, different renters, same scenario, same ending.You see, there was easy access to the roof, via windows over a porch roof from one of the units, and that units renters used the easy access to extend their living space (to the obviously dangerous roof).
