House Update

So we got an offer on our home for $60,000 and the bank approved the price as a short sale (!). However, when the buyer went to do the inspection on the house they discovered that the stove is missing. We did not ask anyone to move it; our only guess is that it was stolen. My question: how does someone get a stove out of a locked house with no signs of forced entry? It doesn't matter, the realtor says that it is affecting the closing. We don't know how but are praying that our buyer wont back out. We also don't know if they will want us to replace the stove (we can't afford this). We are so ready to move on and are so close to the finish line. It is defiantly a headache; please pray for us.
