I replaced a broken railing mount for the interior stairs because a guest noticed it was cracked.The bottom line is to setup processes for yourself (or handy person/inspector) to go over your rentals a couple of times a year.

The new population coming to Detroit are young and talented people who want to be part of the rise of the Motor City. 

Septic field lines failed forcing me to build elgin system in the front yard and put a motor to pump sewer water from backyard to front yard.
