All the effected sheet rock will most likely need to be removed and all effected areas would need to be remediated so it will really depend on how much area you're talking about.

Sort of stuck between a rock and a hard place.

@Haitham Abbasi  If you would throw a rock in any direction I would think you could find a buyer.

I am aware that all of the sheet rock in the house and most of the ceiling sheet rock needs to be replaced and all new floors throughout.

If your house is of this construction, there is no practical way to inject/blow insulation into the wall cavity and you are left with the choice of either gutting back to the studs on the inside or removing the exterior cladding and applying housewrap and rigid insulation on the outside.If you do go the interior route, be prepared to encounter hand-sawn timber with substantial variance in dimensions - meaning you will need to shim and plane, or strap, to create a plumb wall for hanging sheet rock {putting back lath-n-plaster would be cost prohibitive and, in our case (a rental), non-compliant with current fire code}.Old buildings can be rejuvenated and made much more efficient, just factor in an additional 10-15% in your reno budget to address any discoveries.

After that another inspection Thursday on the sheet rock.

It also is using retail prices, which I would hope to reduce by 20% or more once work is bid out, and I figure out what I can do myself, or oversee myself.Getting a rough grading and excavation cost is my first step, and then nailing down all the permits I will need.From what I have seen, under $200 in LA, and Im talking the higher end areas, like West Hollywood, Eagle Rock, Mount Washington, Highland Park, Venice - under $200 would be pretty good, is this a correct assumption?

Welcome from Round Rock!

I've got a customer that had several rentals up there and I hated driving there from Round Rock to handle piddly stuff so tried to find somebody up there.

Daughter is rock solid.
