There's a floor. If you sell a home for less than your mortgage amount you have to have enough cash to make up the difference.

Also, selling for significantly under the appraised price decreases likelihood of qualified buyers because it may be a red flag.

Renting until spring is a logical option when there's no buyers, since that's when the supply of buyers is much larger. I don't want to be a landlord but I also don't want to pay money to part with my house. One home in my neighborhood finally sold for 60% of what they bought it for after 6 months on the market. I think only rich people or people who've been in their homes 20 years can afford that.
