No, you can not get you inspection fees back, sorry. All Real Estate is sold in As Is condition meaning once you close the transaction you buy the problems or defects with the house. You are allowed to do inspections of your choice in a reasonable time peroid to determine if the house has any deficient conditions that will have a negative impact on the investment. Obviously their are multiple deficient conditions with this property. I guess you can look at it you may have lost 1800.00 in inspection fees, but if you did not do inspections it would cost you many more thousands of dollars. So at least you can walk away with only a small loss and not huge repair bills you can not walk away from.
The only time you have recourse for inspection is when the seller refuses to sell with no reasonable explenation (i.e. changes mind) after the P&S is signed.
The Purchase and Sales agreement should explain defecient condition (it protects both buyers and sellers) and state that if the seller is not willing to remedy the problems or compensate buyer for the deficeint conditions the buyer is intitled to all deposits returned.
Some sellers can be real hot heads about repairs. They will never understand that you have already invested time and money in the transaction. This house sounds like it will be a hard sell from hear on out. All realtors are required to disclose any and all conditions they are aware of in the house, so the realtor knows now and must disclose, no one will buy a home at a premium price with all the conditions you stated. Any offers from hear on out will be much lower and take all repairs into consideration.
It all comes down to how badly the sellers want to sell. If they are only trying to cash in on the hot real estate market and make a quick 100,000.00 they may decide to stay put. If they indeed do need to sell they will eventually realize they need to conceed and make repairs.
If you decide to pursue a different house ask the Home inspector you used on the Money pit if they will give you a discounted rate on another home inspection. They should offer you a discount for a second inspection.
Good Luck, I always tell people it will all work out if it's meant to be and if not it's a blessing in disguise. You will find a nicer home or a better value
