I'm not out to do brain surgery on a property like electrical work, plumbing or putting on a roof.

Inspection to follow but they claim roof, electric plumbing were done 10 yrs ago.

New roof.

Passive income can help you pursue your real passion, but who knows, you may become passionate about aspects of real estate:  providing jobs, improving communities, the big checks, the tax savings, or the travel?

I wouldn't tear the whole roof off, just work with the pitch that's already there.  

Renovations to 4 of the 6 buildings include new windows, siding and gutters. 5 of 6 buildings have new roofs.
