first GC didnt have water main repaired in crawl space. this led to moisture problems that cost an extra 3k in costs that he was unwilling to address.

But before the seller could make a decision I decided to accept their previous counter for 80k, but once in escrow I had a friend of mine that's in the restoration industry do a moisture inspection and write an estimate for $10,000 to remediate.

As such, please be aware that from time to time moisture and water may seep in. 

Do a moisture test that you can get from the big box stores.  

I have a tenant moving out this weekend and I heard in her one year living in the remodeled home she wrote a list of issues she had instead of calling me including the moisture in the basement causing the new floor to buckle!

Changes in soil moisture alone results in nothing good. 

Typically termite damage is typically related to moisture. 

The reason mold grows in a home is due to excess moisture and a food source which is typically dust.

You will get better results blowing it into the ceiling.Insulating old wall cavities that were not designed to be insulated can lead to serious moisture problems.If the heat is electric then that is your biggest problem.

I opted for the full 9ft basement as crawl spaces here are a major moisture problem.
