While the easy explanation is that you have a superior property, from the appraiser and bank's POV, I could see them arguing that you will not be able to renew at that rate, and since your loan is outstanding longer than this lease term, they should not underwrite entirely to an above market lease rate.  

Tons of fees? 

Subject to the existing mortgage of 170k @4% originated on 1/1/2022 plus catching up 20k of arrears/escrow/legal fees and then eventually Airbnb Furniture and holding costs of another 15k from private money.

If we were going to buy a property and put it “under contract”, and a better deal came along, rather than pass on one deal we might present it to a fellow investor and collect a fee from the investor in the process.  

It honestly is the only way we can still acquire property in this high interest rate environment.

Ideally you do this if the rates are lower so you don't want to cash out refinance a property if the interest rates are higher than your current rate.

Trying to get the better rate at closing or general appreciation? 

@Gino BarbaroWe got a bid from Caldwell and they wanted 1.75/day per machine plus monitoring and credit card fees plus every year the price goes up by CPI min 3% & the contract is for 8 years. 

If rate come down and  you refinance out of current loan, another appraisal will most likely be done again, no need to pay it twice.  

Cash flow with a 7% interest rate is hard to find, unless you are comfortable with fixing something up.
