Does 700sqft represent the actual surface area of the roof, or is that the square/rectangular area of the floor beneath?

Aside from that, use a floating floor upstairs with an underlayment beneath it.

Turns out the hardwood floors beneath are in great shape but the caveat is that they used 2" narrow staples to fasten the underlayment and they are not coming out.

Kitchen cabinets do not all close properly, some windows still didn't open well, they didn't hire a foundation crew to install piers, they simply used some cinder blocks & shims (with no receipts), and no main line plumbing was updated. 

Then you have your general tools like a vice grip, hammer, channel locks, flashlight, tape measure, composite shims, headlamp, box cutter with extra blades, painter's tool 5-1, wire stripper, allen wrenches, voltage detector, outlet tester, lineman's pliers, good Milwaukee demo screwdrivers, Milwaukee 11-1 with Phillips, flat heads, and 3-4 common size nuts(this is great for appliances).

Bleach cannot penetrate into porous materials and so it does not come into contact with mold growing beneath the surface of materials such as wood and drywall.

I've never worked on mobile homes but on rental houses I go next size down and put in wood material (shims and small boards) to fill the gaps and create something solid to screw through the window into the frame, then fill the gap with spray foam and wrap over with aluminum.

One way is to layer in the new data beneath the old data, then do an advanced data filter on the address column, clicking on "unique records only".

The improvements would not exist if the land was not beneath them. 

Make sure the toilet is shimmed properly if the subfloor is not level.
