If you are looking for a house in the greater Dartmouth area, I highly recommend working with Steve Mazza. He has great knowledge of the area and provides great insights on neighborhoods as well as being extremely knowledgeable on house values. Steve provided great comparisons so we could better understand the market. He showed great patience in working with us. Based on our dealings with Steve we had great trust in his opinions, suggestions, and recommendations. Steve worked hard for us and we found him to be very responsive to our many questions. For us, Steve was a great partner.
Steve helped us in multiple real estate efforts. Most recently he helped us find a piece of property and then tirelessly navigated a long closing. He was proactive and continually reached out to ensure we had the latest and most useful information. His easy going demeanor coupled with extensive market knowledge and perspective makes Steve our perfect real estate partner.
I purchased a home during the Post-Covid housing bubble. Steve was very helpful--showing us lots of available homes appropriate to my needs and coaching me about how to make a reasonable offer. His best quality was his responsiveness. If I contacted him I got a call back. He was great!
