There is no incentive for you to hire a mold inspector and chances are the mold is not a real health issue.

I have spent a fair amount of time "investigating and researching" aspects of business and real estate the last few years, but do to some health issues, there hasn't been time to execute.

Currently I am working for a Health Insurance company but I don't plan to spend the rest of my life there.I am ready to start building my future. 

To find seller financed buildings, the owners have to be motivated in some sort ( retirement, bad health, etc) and you have to be able to solve their problem.  

We told them we weren't raising rents at this time (that put them at ease and gained their trust & cooperation), then we inspected all the units and focused on health & safety issues and deferred maintenance.

In our area the health departmment will come out and do that.

I am concerned that any feces left behind could also cause health issues for my tenants.
