If the whole house is small or too many people are cramped inside, it could be unpleasant. 

Rent by the room to me as a bizz model I dont care for personally. too much work.. now owner occ bring in roomates that different or student housing or as other stated crash pads for airlines thats different. 

By no means do I think it will be anything like the last crash, but I am finding it incredibly hard to find anything that hits the 1% rule or comes close.  

Then I sometimes get this message and the site crashes?

Thanks all for your input so far.To answer a few of your questions I am "not" an "accredited" investor thanks to 2008 crash.          

Most will, but there are some that won't (this was more common shortly after the crash).

Of course 2008 was top of the market before big crash.

You have something much better for temporary assignments than crashing in a hotel.

Are there any unusually unpleasant odors from factories, sewers, rivers, etc.?

I'll never understand why everyone looks for another crash right after the last one.It's as if one has wrecked their car, just got it back from the mechanic, and as they drive off the lot, they start preparing for another crash.There is no crash currently happening, there's not going to be another nationwide housing crash.If by some crazy chance it does, guess what, if your in or out, it don't matter, your bankrupt with 99% of the rest of the county.If your in a state that people say it's crazy on everything they do.
