Called Servpro this morning and they're saying anywhere between $6k - $8k to clean the place top to bottom, including heat ducts, furnace coils, etc. and then running an Ionizer for up to a five days. We may still consider making an offer, but if we do, it will be a lowball to allow for new carpets, flooring, window coverings, and the above listed head to toe cleaning and then re-painting. I'm more willing to give it a shot than the wife is.
