Sellers sell to accomplish something more important. Why are you moving? Is it worth it?
IOW, do you have any reasonable alternatives to selling? Can you keep it as a rental? What if the actual sales price is less?
1. If you are not satisfied with your net, you could try to negotiate a lower commission rate.
2. Most Realtors have a point at which they will turn down a listing, most also need to be able to explain to a seller why they are worth the fee they charge.
3. The real key here is this: The actual selling price for your home, when it sells
The link below says that home values are dropping 1.8% over the last 12 months. I'd be curious what your Realtor would tell you about comps for your price range.
4. Also, depending upon the comparable sales, your property condition, and other market variables, the actual sale price could be more or less. The sale price is based on what other homes are available for a buyer to purchase at the time your home is on the market. That means that the estimate is based on what is going on at one point in time. Once your home hits the market, if there are more homes selling in your price point, you could either gain or lose, solely based on other homes competing for a limited pool of buyers.
You should know that the Treasury Dept. has completed its expenditure of stimulus funds buying mortgage-backed securities March 31st, so most lenders anticipate a half point increase in interest rates, which in effect will decrease home values. Talk with your Realtor about the details.
Lastly, a good Realtor will help you get every dime out of your property, suggestions on what you can do to improve features that buyers like and will pay. Comparing Realtors' suggestions can give you are really good idea if your Realtor knows marketing.
