I have very little expertise when it comes to foundations but, to my untrained eyes, it appears to be a legitimate attempt to fix the problem long term.

Three year roof - to my untrained eye based on my own roof experience, I'd say yes.

Not really any work that needs to be done from what my untrained eyes can see.

You can certainly find lenders and products which will consider the rental income for future loans.I don't have much knowledge of LLCs, but this doesn't sound like the right move to my untrained perspective. 

There was a final walk through of the property, but, as I didn't know about the pipe burst, I didn't know to look for water damage (even after I was made aware of this problem, with an untrained eye, it's hard to notice issues besides some sagging drywall and water drips on parts of the wall) and some part of the wood floor coming up outside of the bathroom door.

Not by the untrained eye.

she listed on her lease agreement she had one small service dog,  which was OK with me until I went to the house and realized she had two dogs, untrained, so I am sure none are service animals.

Honestly that where you can really realize a great return is the intrinsic values that the untrained RE investors eyes cant see. 

For example, many homes to the untrained eye appear to be in bad shape and can warrant deep discounts when in actually they are only cosmetic repairs that can be fixed for a fraction of the cost.

There are different forms and legal issues involved that someone untrained may not know about.I am interested in locateing any property investment clubs in SE Tenn.
