The floor is a black coating over the cement which was the glue correct?  

Not sure yet whether we should do a cement/foundation job for the porch or just re-do the porch entirely.Our adventure here is going to allow us to go through the entire process of flipping/rehabbing our house, but... without ANY of the thorough experience that some veterans may have here.

Deep cement footings, all Trex decking and wrought iron rails - not cheap stuff.

I have used the 1/2 inch Hardiebacker Cement Backerboard and have not had any grout cracking or tiles coming up. 

Three families are built to different standards, requires fire escapes and cement room furnaces.

Two have been sold to pay for completely replacing most of the cement at the complex and doing other needed work, and two more are in reserve for the day when roofs or sewers need to be replaced or something else major that might not covered by the standard 10% of dues reserve set aside.It is an important point that you bring up though.

FYI, old roof with no leak, flash cement can take care of wears, minor cracks, and so on with mesh.

My property had rotting exterior wood siding so we decided to renovate the exterior of the house with fiber cement board as well as install new front door and new wood on the front porch and rear stairs bringing the exterior in line with the other rehabbed properties.  

Newer roof, siding, windows, and cement.
