Basement windows

After the home inspection yesterday on a house we have on offer on that has been accepted, here are the results and I need some advice on whether or not to continue with the purchase: 1) House is on a sloping lot with foundation blocks 4 high and the right of the house and 2 high on the left side of the house. It sits downward of the rest of the subdivision. 2) There are termite tunnels in the crawlspace, age unknown. It has been treated before (probably 5 years ago when the current owner bought it). Live termites were found in the new mulch around the perimeter of the house. The house itself is only 10 years old. Seller will have to pay for the termite treatment, $900. 3) The crawlspace is damp with mold and fungi present that make the house smell musty. 4) There is no plastic in the crawlspace or the foundation walls but it does have about 4" of peagravel throughout the crawlspace. House size is 1200 sq feet. The vents were all closed and the inspector opened them. The house has been empty for several months (owner deceased and family now selling to settle the estate). 5) There is evidence of a couple of new floor joists having been replaced although we don't know when. 6) No humidifier or sump pump was found. 7) Gutters are all clear with downspouts going into the ground and away from the home. We did find some type of "mesh" on the ground around the outside of the foundation where landscaping was done and figured it was to keep the mulch from washing away. Questions: How often should it be re-inspected/treated for termites? What is the appoximate cost of fixing the moisture problem and how successful is the repair? How often do we recheck to see if it is working or not. House is in southern Indiana...humid in the summer months. As far as hiring the work done....lots of businesses advertise in the local yellow pages, how do know who is good and who does a "quick fix". Any organizations/certificationswe should check? I know this is lengthy but we really got screwed on the first house we bought (definetly a money pit) and we don't want to make the same mistake again. Thanks for all your advice.
