Do folks have tools they use with their cleaners to make sure they notice and report damages caused by guests?  

These caused damage that couldn't be seen in my inspection of the MH.  

Had the inspection done and there is clearly work that needs to be done in the $5-$10K range, incl some work around rotten wood, leaky pipes/faucets, holes in doors/walls, small amt of mold in bathroom, sump pump drain issues, bathroom fans routing into attic causing moisture issues...etc.  

I once set up one llc for each property I owned and it caused a lot of headache with no real return on investment.  

Max,The cold more likely shifted/torqued/sheared the fenestration in which the window is installed and it was this force which caused the glazing to crack.  

The rehab drags on cause he no longer cares.  

If your market is a really strong buyers market then that would be a consideration to make it more marketable.Most bang for the buck would be adding a bathtub to the 1/2 bath as long as you don't cause a defect to the rest of the home's appeal by doing so.

I realize that while the cashflows may be higher, the bad area and age of the home may cause issues.

That said, I really think you should speak to your loan officer or mortgage broker first -- just doing something as simple as moving money between bank accounts shortly before closing can cause red flags.  

to answer the question about freezing or pressure causing issues I've had that happen before, though it was user error not crimping the rings correctly that lead to a leak.
