That's a broad question! Berkshire County is fairly large! BUT...to answer that...in the past six months, the average sale price is $264,000 for single family homes.
There are many variables involved in that though...if you are looking for a market price for your home just let me know the specifics (beds/baths/location/acres/condition) and then you can get a better idea.
