- A tax assessment is set by the town for tax purposes only and has no bearing on what a home is actually worth in today's market
- An appraisal is an independent analysis ordered by the bank to confirm a buyer is paying a fair price based on recent comparable sales
- Market value is determined by what buyers are willing to pay, and on the South Shore, that number routinely exceeds both the assessment and the appraised value
One of the most common misconceptions Hillary Birch encounters in her 15 years of working the South Shore market is deceptively simple: people believe a town's tax assessment tells them what a home is worth. It doesn't. And in Massachusetts, where homes routinely sell well above their assessed values, that misunderstanding can cost buyers their confidence and sellers their strategy.
"Assessments exclusively have to do with taxes," Hillary explains. "They have nothing to do with fair market value or what a property is worth."
Hillary Birch is a 15-year veteran Realtor recognized as Best of Quincy and Best of the South Shore, and she has spent a significant portion of her career helping clients untangle exactly this kind of vocabulary confusion before it derails a transaction.
A tax assessment is produced by the assessor's office of whatever municipality the property sits in, whether that's Quincy, Weymouth, Hingham, or any other South Shore community. Its sole purpose is to establish a taxable value so the town can calculate how much a homeowner owes in real estate taxes each year.
Here is where the process breaks down quickly. Technically, assessors are supposed to conduct interior inspections of properties every seven years to update their records. In practice, Hillary says, that almost never happens. What assessors are actually doing is pulling historical sales data, analyzing price per square foot in the surrounding area, and making incremental annual adjustments based on past trends. They are not walking through your updated kitchen. They are not factoring in the new addition, the finished basement, or the landscaping that makes buyers stop on the sidewalk.
That gap between the assessor's snapshot and today's reality is exactly why South Shore homes so consistently sell above their assessed value. The market moves fast. Assessments do not.
A lot of clients arrive at closing having conflated assessment with appraisal, and Hillary is careful to separate the two early in the process. An appraisal is ordered by the lender, not the town. A certified appraiser hired by the bank visits the property, reviews recent comparable sales, and determines whether the purchase price reflects fair market value.
The bank's motivation is straightforward and worth understanding. If a buyer defaults and the bank forecloses, the lender needs to know it can recover its money. No bank wants to be in a position where the buyer paid significantly more than the property is worth. The appraisal is the bank's protection against that outcome.
So the distinction is clear: the assessment is the town's tax calculation, the appraisal is the bank's risk check, and neither one is the same as market value.
Market value, Hillary emphasizes, is simply what a willing buyer will pay for a specific property at a specific moment in time. And that number is driven by factors no assessor's spreadsheet can capture.
"The feeling that a home creates for a buyer is one of the biggest factors in getting the best price possible," she says. "Whether it's a beautiful backyard, whether the sellers have it styled really well, whether they just updated the kitchen. All of these things have nothing to do with the tax assessment."
This is also why direct comparisons between neighboring properties are rarely straightforward. A home selling in the mid-$1.2 millions next door does not automatically establish the value of your home. Every property tells a different story. Condition, presentation, layout, light, and emotional resonance all shape what buyers are willing to offer.
Hillary Birch helps Boston professionals relocate to South Shore communities like Quincy, Weymouth, and Hingham, and part of that work means preparing buyers who are often surprised to find themselves paying well above assessed value. She reframes that reality not as overpaying, but as participating in a market that the assessor's office simply hasn't caught up to yet.
If a South Shore home is assessed at $600,000, does that mean I should offer around that price?
Not necessarily. On the South Shore, homes routinely sell substantially above their assessed values. The assessment reflects a town's calculation for tax purposes, not current market conditions. Hillary Birch Group uses actual comparable sales and current market data to advise buyers on what a competitive and reasonable offer looks like.
What happens if the bank's appraisal comes in lower than the agreed purchase price?
This is called an appraisal gap, and it is a real scenario buyers should prepare for. The bank will only lend based on the appraised value, which means the buyer may need to cover the difference out of pocket, renegotiate the price with the seller, or in some cases, walk away depending on the contract terms.
Why do homes in Massachusetts sell so far above their assessed values?
Massachusetts assessments are updated incrementally and rely heavily on historical data. In a market where demand is strong and inventory is limited, especially on the South Shore, prices move faster than the assessor's office can track. Features that buyers respond to emotionally, like a renovated kitchen or a landscaped yard, are not reflected in the assessment at all.
