Some of the answers below are great advise. Getting remediation can be accomplished and add some value but remember you will have to disclose "all" and this knowledge will still hold a decrease in value to most buyers. Another subject is that anyone purchasing in this condition will have to be a cash buyer because if they are getting any financing the lenders underwriters will pick up from the appraiser notes and require all mold to be remediated by professional contractor and tests with proof that all is clear prior to closing.

To add to what Suzanne said, educate yourself on Mold. The EPA has a very good publication you can get at:
People often react to mold on an emotional level that is far beyond the real impact of the situation. In most cases if you eliminate the moisture that caused the mold to grow, properly remediate it and repair any damage you should be fine. If you get estimates on remediation make sure to check out at least 3 companies and get references on them all. I had mold remediation done on a house I rehabbed and the price estimates ranged from $5,000 to $12,500. The $12,500 guy was basically a scam artist and the $5,000 guy was the most knowledgeable and competent.
Good luck, and don't hesitate to ask if I can assist you further!
Make sure if you want to accept the offer that it is an "As is Sale" and Seller will make no repairs. Make sure your Buyer understands that their buying your Property which its's issues.

I showed an REO home not long ago and the first floor was full of mold. The buyer (not mine unfortunately) required the bank to remediate the mold prior to closing. My understanding is it was done for about $10,000 by addressing the source of the moisture, removing the drywall, cleaning the surfaces underneath with a mixture of detergent and bleach, then installing new drywall. Problem solved and very cost effectively I might add.
Many buyers are terrified of mold because of all the bad publicity mold has gotten in recent years and they discount their offer drastically when there is a significant mold problem. There are ore than a few investors who LOVE mold because they know that it is often easily gotten rid of and remediated and they know they will get a HUGE discount on a home with mold. Often the cost of remediation is far less than the discounted offer. You would be doing yourself a favor to get a mold specialist in so you have the facts.
