I have properties in 5 states and there are many days I wish my tenants in the 4 other states would burn the places to the ground. 

When people call this number, the caller ID shows as my business number and not my mobile number. 

I would just take plenty of pictures to document the current condition and explain (in writing, perhaps an addendum to the lease) what you will consider beyond normal wear and tear, i.e. marks, gouges, broken door knobs due to excessive force, etc...I know as a tenant it would be hard to have a landlord say you're worried about their little "angels" but hopefully they can emphasize once they realize that you have been burned before.

Well if the house burns down..

It being a mobile home might also having something to do with it.

I also have a brick front , and it sucks up the heat  ( great in winter)  My front door in the late afternoon , if you touch it you will burn your hand .It was worse until I added a vent fan in the attic and I tinted the front windows , I also have a window unit in 1 bedroom so I could balance the ductwork to send more to the living areas. 

I finally made the leap and paid my "tuition to the school of hard knocks" last year when I purchased a singlewide mobile home to repair and rent.

Plus if things go south and you can't sell for as much as you intended, then you may be over promising your contractors a bigger paycheck which could burn that bridge.

Unless they've been badly burned with a poorly constructed house in the past, they won't appreciate over-building.Save that stuff for custom construction.

We also do not finance vacant land (lot loans), manufactured homes (mobile homes), working farms, or condotels (condos that rent rooms on short-term leases or are located in hotels).
