I put on 4-6 foot down spouts and place a cement channel at the end.

That's a standard they interpret very strictly.Common failure items include peeling paint (even a tiny bit), cracked glass, loose hand rails, crumbly cement steps and rotting wood trim.Go for the FHA 203K construction loan or a portfolio loan with a local lender. 

A small shower leak retiling with new cement boards costs $10,000 in central Jersey!

There is a 385' living room, 12x35' back porch overhang with cement pad under It, 16x25' morgan building shed, and a 8x10' shed.

If you have cement slabs, you can consider tile as a decent choice for your area, wouldn't do up north, too cold.

Cost for current building tear down and removal, dirt work, cement work, electrical, sewage, and container cost will be around 315K.

In 1978, the Italians went "all in" with the Fair Rent Law that set 4 years as the minimum duration and cemented rent control.After the initial 4 year contract is up, landlords may remove tenants in order to sell their properties.

Common failures are for peeling paint, cracked windows, loose handrails, crumbly cement steps - and all of this applies even to out buildings like sheds. 

Just going down to studs, redoing cement board and walls, new tub, new shower attachements, new tile in shower and on floor and then re-installing the cabinet, toilet and vanity I have already done. 

If your only talking about wood flooring, then I would think around $1/ft2 would be reasonable price, carpet would be super cheap, as it only takes a few minutes for a room and tile would depend how its installed (cement board or mortar base), but likely higher than wood flooring removal costs.
