I do enameled steel replacements, but that has its own series of headaches and a learning curve that you have to get used to.

@Robert Steele Great point, Robert.

(They have a small hole next to the key slot.)When a tennant moves out, you use the old key to turn the lock 1/2 way, put in a new key to turn it back, boom, rekeyed lock.

I find stone countertops, cabinets, stainless steel appliances (with washing machine) and a washer dryer can increase the rent roll.

As a side not the area I'm looking into is a a place slot of people are investing in.

You can go in and salvage any steel, appliances, or siding you think might be useful for the new build. 

There's no steel frame underneath as they've never had wheels on them, they get delivered on a truck and assembled on site.

@Robert Steele  I understand your position.I'm a big fan of personal responsibility, and I don't think it's too much to ask for tenants to pay rent without having their hand held.

This door also usually starts out as glass, but usually the first time after a junkie smashes the glass pane and crawls in to rob the place of a couple packs of cigarettes, cthe steel of the glass door frame gets a steel plate welded over it and is held open from the outside with a rope that attaches to an eyebolt driven into the side of the building.
