You are going to need to wash it and then maybe even seal it, use Killz and something similar not too expensive.

House was sealed up for two weeks and fumigated.

(you may need a 3 lb hammer to tap around the cover a couple of times to break the seal) Be careful not to hit it hard enough to actually break the cover completely.

I was in this situation a few months ago competing with other investors and the thing that sealed it for me was my lender- great guy, great reputation and does what he says.

So, there is now a system that builds in a predatory practice potential.Standardized forms and systems can work to justify reasonable fees to be charged my MO, while it needs to be profitable, it needs to be fair as well.I'd probably process a SF deal, complete the standardized form, note and stamp it with my seal for $500 all day long.

Prep the interior of course but then I would pressure wash and water seal the brick.

And big red wax seals proving the taxes to the crown were paid.

I installed a tile floor, grouted it and then sealed the whole thing.

I'd paint the floor with Kilz for good seal, something I've used with pet odor in homes to block off and seal the odor then lay down the carpet/tile/hardwood/ or vinyl plank flooring. next, what are  you trading off by doing this - might be cheapest but is it really?

I'm planning to pull ALL carpet/padding/drapes etc. and then seal the walls with Kilz.
