We met Sal when we purchased a home in 2000. Then we also used him when we sold the hoouse in 2003. So now when we decided to move back to MA, Sal was the first one we thought of. We actually relied on his judgment through the majority of our choosing the house we wanted. He was very clear when it was not his area of expertise and hooked us up with experts that he personally could vouch for.
I highly recommend Sal for any buying/selling.
