Remove the drywall and replace it with cement board.

This issue would be whether or not the type of work needed a lot of water (cement, soil irrigation, etc). 

4 inch hardening cement $7,000.00 11.

Then denied Section 8 because there was older "cement paint" on the driveway that had partially been stripped away.

We get bags of concrete, cement, sand, etc for $1 (any size or brand) if it has a hole in the bag.

It bolts to the cement pad in what looks like an hour's worth of work.

You might also look into changing the external cladding to a modern siding (if permitted): Vinyl siding or cement/fibre board will typically have a 25-30+-yr life (3+ paint jobs) and is much lower maintenance than wooden clapboard or shakes.

It has the foundation (cement) already done and it's in a nice area.

Is that cement or stucco and mud over the bricks?
