I even called a city inspector who had been through the house and got an idea of internal condition. 

I think that you need a better inspector and inspection check list... that seems to be where the break down is.

So when the inspector saw that the smoke detector wasn't working,  the inspector asked the tenant why the smoke detector wasn't working. 

So we bought into the idea that it’s a great investment. we went non contingent over asking but just not happy with the way the deal went .. reluctance of our agent to spend time on the property  and when we went for inspection with sellers inspector the seller agent was present and that didn’t give us room to ask questions and really inspect and feel the property to our liking… I am not sure if it’s just a feeling that goes away or will this be a terrible mistake .. earnest money is also a very large sum

I recommend asking an licensed inspector to do this for you.

I can never know for sure if the pipes or wiring was replaced (my biggest concern), I don't think an inspector can actually tell as well since you have to tear down the entire house.

And yes a good inspector should be able to notice foundation issues.

Taxes much to high ,and the inspectors are very difficult.

Then the PMC can accompany the buyer/inspector/appraiser to view the property - as long as the owner is somehow compensating them for their time.

Do you have an inspector, CPA, attorney, title company to help you when you begin?
