They came down hung out with me three or four times in the past year, they have finally lost the Guruitis they had been infected with when they first called.

My realtor was too busy to show the place to me because he was selling some personal belongings, including an automobile. 

If you had an infection, would you try to prescribe yourself antibiotics?

In NC, your sales may be considered personal property since a MH, unless explicitly declared and recorded as permanent, are personal property (like an automobile) and financing and sales rules are not like selling a residence.

REI thought they were immune back then too.

If you keep track of your mileage driven for the rental then multiply that by the business mileage rate (2016 0.545 cents per mile) to get your total automobile expense related to the rental.

A diplomat is interested; but I am not sure about renting to such applicant due to immunity concern(you cannot evict such tenant, etc). 

They are very good about giving out low rates on automobile loans and credit cards.

So true for SFRs, but the MFU 5+ has multiple rents and the more doors, the more immune you become. 

Just like an automobile that is nickle and dime-ing you, at some point it's best to buy a new one.
