I rented an insulation vacuum, vacuumed and disposed, cleansed the attic, installed baffles and wind blocks, and reblew the insulation and saved about $4500.   

And yes, a day will come when there will be a "cleansing of the pond," and only the best will survive. 

All in all, the industry is going through a cleansing process, the days of buying real estate with mediocre credit score and low downpayment are just about over (if they're not already).

Once man is gone from the earth, it won't take long (relatively speaking) for the earth to cleanse itself of most of the evidence that man was here.The reason we need to take care of the earth is not for earth's sake, but for OUR SAKE.

Man has sinned and sinned and sinned and the only way for God to cleanse these sinners was to arrive on earth in human flesh and die on the cross in the form of Jesus Christ.When Christ died he took the burden of sin with him.

But "mold in the blood" is a scam, typically followed by "Detoxification Treatments". 

The oven dishwasher refrigerator and microwave were all cleansed prior to leaving the home.  all nail holes from pictures or mirrors were spackled and painted.

Depending on whether a hardwood floor is finished with varnish, shellac, lacquer or polyurethane, you'll need to use different cleansing methods.

If you have time, you might want to go through the list and cleanse it up to improve your chances.

Do expect it to come out and rather be upfront, mention in passing that someone died in the house (heck, most old houses have had people die in them, most in their sleep, though).I would definitely do a cleansing to get rid of the negative energy.
