Had structural issues (wall caving in) that I addressed a couple years ago.

Hi, pre foreclosure in all of its permutations, before the bank sends Notice of Default (NOD) or efter which is state even county dependant but often starts a 4 week clock till the trustee auction are the 2nd most difficult deal scenario and IMHO only experienced investors should bother, the 1st most difficult deal scenario are bidding at the court house steps on lord only knows what is being auctioned off sometimes even 2nd mortgages, you need to do so much home work to attempt to reduce your risk at the court house steps...Pre foreclosure no one talks about these issues, always about the nice sounding stuff like "motivated seller" get a good deal etc etc both are usually not the case.- 95% of folks in pre or post NOD want to stay in their house, keep their house inspite of them 100% will loose the house at the auction. 

Appraisals are always an issue due to a lack of comps.

If that is the case, can you start to buy places that are built in the mid-90s to stay away from those big issues?

The only issue I've had is a small period where the laundry pods would always be empty at turnover. 

Yes, companies allow mortgage deductions from a savings account without issue. 

If a 10 year investment horizon is an issue than this is definitely not for you.  

Maybe it has more to do with the software than the company (although their customer service sucks), in which case you might run into the same issues with other emulators, but it has just been constant headaches.

It must make selling a house IMPOSSIBLE until its paid off since the same issue sounds like it would apply.
