A note about the value of your home:
Your property has many values: one to the tax assessor, another to the lender, the insurance company and yet another to you....
It also has a different value to the prospective buyer.
The market ultimately dictates the value based on current conditions such as; supply of buyers and competition of similar homes on the market.
Buyers engage in comparison shopping. It doesn't matter what the product is a new car, groceries, or a house... buyers are comparing for price, amenities, value, etc.
Properties that are priced right sell faster and for a higher price.
Ultimately the best price obtainable will be determined by the market itself. It is unlikely that a buyer will pay more for your property than for a comparable property, in fact over priced properties help sell the competition!
