It can usually go right over existing flooring, and note that some floorings may need a moisture barrier, like cement.

Saw cracks in outer cement wall as well as higher on the wall towards the ceiling interior and where the ceiling and wall join together.

While adding an ADU in my basement I removed the plastered walls to insulate behind them and covered up some holes with cement that were found in the shiplap attached to the house. 

Property needs all new fiber cement siding, fascia, window frames and sills, minor front brick foundation repair.

Any cement previously drilled through where a termite company injected their chemical and patched the concrete?

Hardie boards are not being considered, too heavy of a cement-like board, There are past foundation slab issues also I am on dirt that wasn't graded right by contractors when it was built, also clay dirt.

I do see a potential problem with the foundation but I think it should be able to be corrected (when looking at the house from the front, there is some cracking along the cement portion of the porch but nothing else is visible to me at this time).My question to the community is: would this property be worth renting? 

Today he took out the old 14 by 14 feet small roof and put torch down rubber roof with flashing cement.

Old would be virtually anything else - galvanized, cast iron, clay, cement, asbestos-cement (AC), or orangeburg.

HWH first; someone cemented the fittings onto the heater itself so I had to cut the pipes after I drained everything only to see the effects of no drain pan in place.
