To find out what your home is worth in Andover, MA, ask a local agent for a comparative market analysis built on recent Andover sales. Don't rely on an online estimate. Zillow's index puts the typical Andover home value at $999,919 (mid tier, August 31, 2026). That is a town-wide figure, not your house. Lillian Montalto Signature Properties International walks through your home and prices it against nearby closed sales and the listings you would compete with.
Why isn't an online estimate or your tax bill enough?
Neither one has seen your house, so neither can account for its condition, updates or lot.
An online estimate is a model. It averages recorded sales and can't tell a renovated kitchen from an original one. Your assessment is a tax tool. In FY2026, the average single-family home in Andover was assessed at $1,072,150 (Town of Andover). The town sets assessments on a fixed schedule from prior year's sales. Buyers pay what the current market will bear.
How does Lillian Montalto Signature Properties International value an Andover home?
Lillian Montalto Signature Properties International prices your home by hand, from MLS sales, in four steps.
The walk-through. An agent tours your home and notes its square footage, layout, updates and condition, plus anything a buyer's inspector would flag.
The comps. The agent pulls recent closed Andover sales of similar size and style, then adjusts each one for its differences from your home.
The competition. The agent reviews active Andover listings. Those are the homes your buyer will see the same weekend.
The range and the plan. You get a price range and a recommended list price, with the reasoning written out.
Items 84 and 86 in the firm's "102 Ways We Can Help" booklet cover this work: analyzing local market data and supplying comparable properties. You can ask the office for a copy. To start, request a valuation at andoverhomes.com/home-valuation.
What does the current Andover market mean for your number?
Recent sales move fast in Andover, so your valuation has to use the latest closings.
| Andover, MA (Redfin, 3 months ending Aug 2026) | All home types | Single-family |
|---|---|---|
| Median sale price | $1,051,804 (+11.3% YoY) | $1,199,297 (+15.04% YoY) |
| Median days on market | 21 | 20 |
| Average sale-to-list ratio | 102.74% | 104.24% |
| Inventory, end of period | 87 | 61 |
With single-family prices up 15.04% in a year, a comp from last summer understates today's market. And end-of-period single-family inventory was up 74.87% from the year before, so buyers have more to compare you against. Like most towns in Massachusetts, the market is shifting. A good valuation accounts for both. Once you have your number, the LMSPI selling process shows how the firm markets a home at that price.
