I can't tell you how frustrated I get when I am showing a buyer a home and it says in the MLS that the seller is trying to retain their mineral rights. This may be a problem exclusive to North Texas, but I think the theme is a national one.
When you are trying to sell your home as a short sale, don't be greedy. Losing your home may be the worst thing you have to endure, but showing a dirty, unkempt home is only going to prolong the painful process.
When trying to short sale, buyers want to see a place that is just as nice and well kept as any other property. The short sale home is already at a disadvantage because the process is so difficult and lengthy. And recently I have been hearing that banks want to net a high percentage of the appraised value, so often times they are not the "steal of a deal" that would justify such a hard process.
But what it boils down to, don't exclude the drapes, the lighting fixture, the BBQ grill, etc. Include everything that is attached so you can sell the home and move on. And don't try to retain an entity that can live on beyond the transaction. It makes you look difficult, and you don't want to start off the transaction looking difficult.
