@Dave Bopp - at that point they would be considered a holdover tenant and your lease should cover that. 

Some lenders may offer to cover closing costs in return for a higher interest rate.

In her book she said if a investor put a deed in a land trust to cover up the due on sale clause, this action could be consider a mortgage fraud; because if a court rules that the intent was to keep the bank from exercising its legitimate rights by hiding an important fact (deed transfer), I can be accuse of mortgage fraud.

Second, in the contract is there wording about them marking up the repairs to cover their time? 

Evaluate your current lease and make sure you covered for these frivolous costs in the future

At most there would be some additional utilities and cleaning expenses, but that *should* be easily covered by the airbnb price based on my research of homes in my neighborhood on airbnb.

But if you are looking to hold it long term and just cover your mortgage there are still some good locations to buy in that will likely appreciate well. 

Hello, I am looking for a good rental home insurance agent in the midwest who covers Alabama, Tennessee, and Indiana.

That will make the cash flow on the refi property negative $165 but the cash flow on the new property covers that.  

Contact your insurance provider and see what they will cover and the cost of that coverage before considering purchase.Unfortunately a pool has a negative impact on the bottom line not positive.
