And, if you didn’t have the money you could buy them a couple of heaters to get through the first winter.The metal roof appears newer and in good shape.No HVAC.Water heaters are in good shape.The building is structurally sound.No termites at time of purchase.The carpet was in such bad shape I only saved 6 units and the Carpet Cleaner assures me the carpet will come back to life.

The oil burner we replaced was burning a gallon an hour when running and it ran 12 months a year due to domestic coil.

When I started with my first project in 2018 I can say that materials were considerably less expensive...recently I went to Home Depot and the electrical wire was safeguarded by a metal cage that required an attendant to access.  

Maintenance- check buildings, wood/metal, roofs/leaks, door repairs, g. 

I retain the master code AND the metal key.

So you may have to go with a cold process or self-adhered method.There is even the metal roof option of course. 

I 2nd what @James Wise said, but if I were going to do it (and I was not working with load bearing walls, I would focus on the back area and hall.It really comes down to what our close in competition is getting and what their offerings are.If you see a more tidy, rain protected look getting more money without sitting on the market too long, or you don't want to offer something too downscale (looking for a little better renter--hopefully)....maybe focus on the hall and back door.Some of the things I see that can could the possible rent a little better might be, door types, a rain roof, concrete patio and trash areas, a cellular door bell on the bottom, an outdoor modern looking pigtail florescent light (day lighter), the interior hall with commercial tread covers and lighting like the sun (day lighter) as well as a sturdy metal handrail or two, and a window at the top.But as James said above--beware of spending when you don't have to (but that's your call depending on your close in competition).Good Luck!

If you short him 3 squares of shingles, 5 pieces of drip edge and some L metal, he won't work for you for long...

I make things with metal.

Call lots of mobile home companies to see if they will haul it off cheap and put some ads on Craigslist to see who will tear it down and can have the scrap metal.
