You need to do an assessment on asbestos and lead based paint for this home before you do anything with it - the materials were completely uncontrolled until HUD began overseeing construction of these in 1976.Also have someone get under the home and look at the wooden trusses and frame to make sure it's in good shape and serviceable - many times these will be bent from multiple moves and the floors may seem wavy and unable to level them out.

The kitchen is out dated and has original cabinets and countertops (both wooden in color).

Not only that, but the pool is built on a wooden platform.
