No, but I once had a someone break into one of my properties by pulling the power meter in order to bypass a security system.

When I'm sifting through potential investments I do a simple rough estimate using the 4 square system to evaluate the potential cash flow.

I had to pay for an appraisal on both properties as not all their properties work for the implied value system they use.

Are the rents controlled or are they the right price. 

The price you were quoted is 1) a HUGE spread so something fishy is going on 2) a new system for a house 1,400 sq ft would only run about $8,000 with completely brand new duct work on the entire house, new compressor, and new furnace.

My monthly sewage, water, garbage removal, insurance, and pest control is around $450/month Once the third unit is rented, my numbers will be even better!

However, the agent didn’t control the insurance company, and they, for whatever reason, didn’t allow the claim.

My point was that your experience supports my observation in the sense that I think they are trying to be "market makers" and sort of control prices. 

That doesn't last long because you end up with hours a day you are not selling and just helping others sell.I would recommend talking to other agents in the area and see what kind of support systems are available.
