It depends on the property and your market. In Chester, MA ... there haven't been a lot of sales ... on average, properties have sold within 94% of the asking price. How many days has the property been on the market? On average, homes in Chester have been selling at 89% of their original asking price .. but condition of home, neighborhood all factor into this.
Now ... in Middlefield, properties have been averaging being sold at 93% of asking price and 92% of original price with one well priced house selling in 2 days at 100% of asking price. However, again, not a lot of activity to be basing these numbers on ... it is really going to depend on the exact property you're talking about.
If you'd like to work with a buyer's agent, I'd be happy to refer you to one. I'm not out in Western Mass all that often, but I do know a couple agents who work out there. Let me know if I can help! email@example.com... more
