Obviously, having a preapproval letter is critical. 

I'm going to write up a contract termination letter to the tenants. 

I would like to sell the property to the restaurant operator and they are willing to buy. i want to hold the paper on it to get the interest and what I'm hoping for is deferring the capital gains taxes until the balloon payment would be due in 5 years.

In retrospect...this was probably a "meh" financing choice in my opinion, not sure if I would do it again.  30 year terms, no fear of balloon, that's great. 

I met a realtor/banker who was making DOT/Note loans for pot farms at 50% LTV, 12% interest and a balloon in 2 or 3 years.

These allrequire applicants to submit an acceptable Letter of Explanation addressing each specific issue and occurrence.Rental HistoryBecause a current landlord may say anything to get rid of a bad tenant out of desperation, we also requireinformation for the previous landlord of all applicants.

Commercial, private, seller-financed, had a balloon  or the rate was 6% plus (in a 4% world) or I needed to get rid of a small one to get a new one.   

Do I Call, Write a letter, Door Knock? 

The important part is ensuring you have the ability to refinance when a balloon comes due.

Normally a letter by an attorney to the Attorney General regarding that kind of fraud gets the ball rolling.
