I don't have the numbers for the whole state, but in Sandwich in the last six months it was 92.45%. That may not reflect the initial asking price of the property. If you are buying you can offer anything you want and work upward, there is no shame in low balling a property. You must be willing to walk away from the deal if you want to stick with a low number.
As a seller you should price as close as you can to what you expect to sell it for and if you are getting offers hold on as close as you can to the price.
Both sides need to gain something from the transaction and it isn't always the highest price.
