But, usually the problem is other things....no rotten wood, no peeling paint, no "trip hazards", electrical and plumbing up to code, windows must function properly, etc.  

Debating if should get in there, un-winterize it, pay the heating bill & electric through the winter. 

The building we did get had been left unmanaged for 9 months, the owners had just stopped collecting rent and the tenants kept paying for water and electricity, so they had it pretty easy.

Or what if he hired someone who was also unlicensed (since he obviously doesn't see the need for licenses) to take care of some electrical repairs and the next day your house caught on fire because of faulty wiring? 

I always put them in if the property was a total gut renovation with all new bathrooms, kitchen and electrical.

In my experience most issues that need immediate attention are water / plumbing related and to a lesser extent electrical.  

Residential parks are almost exactly like MHPs and tenants pay monthly and then are billed back for electricity and sometimes other utilities.  

I wanted to quiz the members about a few things:If there is no insulation and the tenants pay for electric heat, is it worthwhile to include insulation costs for attic and floor in the initial loan?

Hopefully he didn't short you on electrical, plumbing, etc.

Inside the premises we find damage from their burning candles for light (electricity turned off by power company for non-payment), smoke detectors dismantled, broken window, etc.
