One thing to remember ... The inspection is part of the price negotiation process. Way too few buyers recognize this.
I almost always go back with another offer after the inspection. That's the time that they're negotiating only with you, and the house is probably off the market or at least not being actively marketed. The seller and the selling agent know it's going to be a pain to start marketing and showing again. They're both seeing dollar signs at the end of the process. They want the deal. Now. This is especially true if the seller is a bank.
A good inspector will find a few issues that you weren't aware of. Show the issues and come with a new price. If you go back with a lower price there are 3 things that can happen:
1> The seller accepts your new, slightly lower price.
2> The seller counters with a new price between your old and new price.
3> The seller says no. At which time you can reaffirm the old price and go forward with the deal as originally written. In about 15 transactions that I've offered a new price after the inspection I've never had a seller walk because they were miffed at the new price. They may say no to a new deal, but the deal will get no worse than the one you have now.
If you like everything about the house I'd still go back with an offer that's 2% below the original price. If you find significant problems adjust the price downwards more. But now is the time you have maximum leverage. Don't let this time pass without at least considering pushing for a concession.
