Hmm, let’s see….symptoms: Shakes Chills Sweats Blurry Vision Cramps Blah feelingYup, the Bigger Pockets site is down!

Certainly not a symptom of a depressed area.The population is not aging - there is a strong mix of working age population 20-60. 

I can cite numerous instances where killing mold in an area occupied by hypersensitive people did NOT stop their symptoms.  

These symptoms can also be just allergic reactions, as you mentioned, and not necessarily some sign of a serious illness created by mold. 

Kellie-I've run across this issue before, and generally (as has been mentioned) this is a symptom of REO brokers who are far too busy.

I am a disabled veteran who served in Iraq, so I'm fully familiar with many of the symptoms you described. 

I'd agree with the previous posts and have a contractor or engineer do a quick inspection to make sure the bowed floor joists aren't the symptoms of a larger problem (i.e. sinking foundation).

I think the difficulty is a symptom of market conditions. 

I suppose the only question I'd have is with this size of a house and only a couple would the daughters and granddaughters soon be moving in also.For what it's worth, I've got a tenant couple who are in this late 60's and both have medical problems (he with heart disease, she with significant diabetes). 

Of course, I readily admit that's about as helpful trying to self-diagnose via a symptom search on WebMD.It does seem to my laymen's eye that an STR could, in fact, be thought of as a modern-day boarding house, just with different technology and a remote host.
