Fix one corner of the foundation, some brick repair on one wall, paint, minor landscaping, and that's it.

How thick are the walls?

Walls are down to the studs.2.

ranch, 1050 sq. ft, basement (poured walls), 3 beds, 10x10 kitchen, detached garage

If nothing else, through seams in the individual slab sections.One of my pet peeves is actually another technique that is pretty common here for the exterior walls of buildings, as well as concrete fences - leaving the raw concrete exposed to the elements!

Any time there was damage that the tenants did to my property (holes in the wall, broken locks, etc) the housing authority withheld rent until I fixed it.

It appears the previous owner did put in new vanity and toilets, so it was really just be updating the flooring and the wall tiling.3.

If you are able to rehab the mobile homes and leave them in their current location this would be ideal as you will not have to pay for the homes to be removed and transported, also the park will keep these homes inside their walls so that you may continue paying lot rent monthly.As an active mobile home investor you will be bringing a lot of value to the closing table besides $250-$1000.

Not saying to not take a mortgage, I am just saying, if possible, not go balls to the wall and mortgage every property to the hilt.  

I noticed water damage on the ceiling and wall of the main bathroom.
