Today was expensive. We had the home inspection ($225), plus additional testing for mold, because there was moisture under the crawl space. I hate to spend the extra $175 for that, but it's better than being stuck with a mortgage and a house full of toxic mold, right? The inspector thinks the dampness is from condensation on the ductwork. They are installing a new heating and air system tomorrow and wrapping the pipes.
I'm praying that everything works out okay! It would be hard to walk away from this house, but that's what I'll do if I must.
