First of all, if you got an offer, good for you. That means you were priced well enough to sell the Real Estate agents on showing your Big Bear home. Now you'll need to get your ego out of the way and see if you can get your home sold before it looses any additional value. Most buyers in this market are investors, or they think like one. If your lucky enough to have a buyer that becomes emotionally committed, you are very fortunate. You are handling an endangered species, so be careful. Buyers in this market are illusive and hard to find.

It's kind of like fishing for hours, and then you get a bite. The first thing you want to do is pull hard and get them into the boat. You might have caught a few fish before, but these fish have very soft mouths. It's almost like using barbless hooks. Just enough pressure to keep everything moving in the right direction, but don't let them off. Once you get them in the boat, use 2 hands (they are slippery).

Ask your agent to give you an up to date market analysis to value your property. Remember, this buyer has looked at your best competition, and the last sale in your neighborhood is more than likely the new ceiling. Remember when the last sale was the new floor? Those days are over for now. Take a good look at the comps and be reasonable. Your agent wants to get you the most that they can for your property, but nobody gets paid unless their is a close of escrow (including the seller).

Always give a buyer a counter if you are not going to accept their offer.If your Big Bear home is price well, chances are the buyer is still going to try to buy it for 10% below your list price or more. If the offer you receive is $50,000 off of your list price, you are much closer to putting together a deal than you were before you got an offer. Often as a seller you have counted your eggs before they have hatched and you've made plans for all of the proceeds of the sale, but the market has probably changed since you settled on the price. 

If your not willing to have some flexibility, I suggest you pull your house of the market and stop wasting everyones time. Buyers in this market are in charge and they know it. This market is for serious sellers only.

If you are telling your agent lets just price it where I want to and see what happens, they should be telling you that they already know whats going to happen. You are going to sit on the market while you loose more value, so don't list with a lets see what will happen attitude. You'll need to price your home at or below market value.The best thing you can do for yourself and the market if you are not motivated to sell is to pull your listing off the market.
