Assessed Value vs. Market Value vs. Appraised Value: What Homeowners Should Know

Market value is the price a property would most likely bring in a competitive and open market under fair-sale conditions. In plain language, it is the number most homeowners mean when they ask what their house is worth right now.

This number is shaped by current buyer demand, recent comparable sales, location, condition, inventory levels, and timing. It is not static, and it can move faster than tax assessments or older valuation opinions.

If your goal is to understand what your home could realistically sell for today, market value usually matters most. That is why homeowners thinking about a move often start with current pricing strategy and seller guidance, not just the number on a tax bill.

Appraised value is an appraiser’s independent opinion of value for a specific formal purpose. In many cases, that purpose is tied to a mortgage, refinance, or another lender-related decision, but appraisals can also matter in estates, legal matters, and certain financial planning situations.

An appraisal is usually meant to support an opinion of value as of a specific date. It is not simply a guess, and it is not supposed to mirror a municipal tax assessment. It is its own process, with its own standards, scope, and intended use.

That is also why an appraised value does not always match a final contract price. A sale can reflect negotiation, competition, concessions, timing, and risk tolerance in ways that are not always identical to how an appraiser arrives at a formal opinion of value.

Assessed value is the value a municipality or tax authority uses to calculate property taxes. It is a tax number, not a listing strategy and not a lender appraisal.

Depending on where you live, assessed value may reflect full market value, a percentage of market value, or a periodically updated estimate tied to the latest local revaluation. The timing of that process matters, because tax assessments often move on a different cycle than the market itself.

That means an assessed value can be useful and legitimate for tax purposes without telling you exactly what a buyer would pay if you listed your home this month.

The biggest reason these values differ is that they are not trying to do the same job. One is meant to reflect what a property would likely sell for, one is meant to support a formal opinion for a specific purpose, and one is meant to support a tax calculation.

Timing matters too. A market can change quickly, while an appraisal reflects a point-in-time opinion and an assessment may follow a revaluation cycle. Even when all three numbers are reasonable, they can still be different because they were created for different audiences, with different methods, on different dates.

That is why a homeowner can have a market value shaped by current demand, an appraisal tied to a refinance or purchase, and an assessed value tied to a local taxation system, all at once.

The best way to reduce confusion is to match the number to the decision you are making. Each value becomes more useful once you look at it in the right context.

If your question is, “What would my home likely sell for right now?” market value is still the number that deserves the most attention. If your question is, “Why is my tax bill based on this amount?” assessed value moves to the front.

State and local rules can make the relationship between assessed value and market value look different from one place to another. That is part of why homeowners across Southern New England sometimes compare numbers and reach very different conclusions.

In Massachusetts, assessments are intended to reflect 100% of full and fair cash value, which is commonly referenced as market value for taxation purposes. In Connecticut, real property is generally assessed at 70% of estimated fair market value as of the revaluation date. In Rhode Island, municipalities generally use estimated fair market value for assessment purposes, but revaluations often happen on a cycle rather than in real time with the market.

The practical takeaway is simple: if the numbers do not match, that does not automatically point to a problem. It often means you are looking at different tools designed for different uses. The more important question is which number helps you make the next decision with confidence.
