They go really wrong! I had a listing that went under contract within the first week on the market. The contract price was less then the seller's wanted (when isn't it) but we negoitated an as is clause meaning NO repairs at inspection and everything seemed to move forward smoothly. The buyer's attorney didn't care for the no repair clause but the attorneys worked through that and we moved on. Home inspection showed some minor problems but seller's attorney reminded the buyers that repairs were basicly built into the sales contract price so take it or leave it, the seller's were making no repairs. Buyers want the house. Fast forward to one day before commitment, 1 week before closing, we receive a letter stating that the buyers want to be compensated for repairs with a $4,000 reduction in purchase price. When the seller's attorney responded that they would consider doing some repairs but would not discuss the situation until we had a commitment we received a letter killing the deal. I am left with unhappy seller's and a house that has been off the market for 6 weeks.
