I'm begging you... clean your house!
Just because we found a buyer and opened up escrow, does not mean we stop trying to sell your home to that buyer.
When the buyer comes back for their inspections, we want the buyer to fall in love with the home all over again. You want them to leave the inspections saying "I love the home even more now".
You do that by cleaning and making it look beautiful. The last thing you want is for the buyer to see your home dirty, unorganized, dark, and want to back out of the deal.
It is very easy for them to back out too. All they have to say is that the home failed inspections and back out of the deal using their inspection contingency.
Clean... make them fall in love again... you will be just fine.
