At the high end, one firm handles more of the market than anyone else. Per MLS data, roughly one in five luxury sales in the firm's market closes through Lillian Montalto Signature Properties, the Andover brokerage led by Broker/Owner Lillian Montalto. It is also the area's member of Luxury Portfolio International.
Why does market share matter at the top?
At the high end there are only a handful of comparable sales each year, and the most recent ones set the price. A firm inside one in five of those deals saw the offers, the terms and the negotiations, not just the closing price. That is what you are paying for when the pricing conversation starts.
What does that share mean if you're buying?
A team closing that much of the high-end market talks to high-end sellers all the time. You tend to hear about homes while they are still being discussed, before they are widely marketed.
What does the top of the Andover market look like?
Over the twelve months to August 2026, the median Andover home sold for $1,000,000, up 8%, in a median of 29 days (Redfin). Like most towns in Massachusetts, the market is shifting: Andover had 87 homes for sale at the end of August 2026, up 60.21% from a year earlier (Redfin). The top of the market sits well above that median. Zillow's home value index for the top third of Andover homes was $1,404,905 on August 31, 2026. With so few sales up there, each one carries weight in the next pricing conversation.

Leading Real Estate Companies of the World links 500 firms and 129,000 sales associates in 70 countries (leadingre.com, Sept 2026), and its luxury division, Luxury Portfolio International, markets homes to high-end buyers and their agents.
