Your postcard arrived last month. Your assessed value went up. The Facebook groups lit up. Your neighbors are comparing numbers. And somewhere in all of that, the same question keeps surfacing: does my tax assessment actually reflect what my home is worth?
I’ve been trying to answer that question since 2009.
I first ran the analysis back in 2009, then updated it in 2024, and most recently reviewed the last 12 months of closed sales in Bernards Township — 306 transactions in totalAnd after 16 years of looking at this data across wildly different market conditions, I’m going to give you the most honest answer I can:
There is no reliable, consistent relationship between your tax assessment and your home’s market value in Basking Ridge. And I think that’s actually important to understand.
What the Numbers Have Looked Like Over Time
For a long time, I had a rule of thumb I could actually use. Whenever I ran this analysis — and I ran it regularly over the years — homes in Basking Ridge were selling somewhere between 6% and 10% above their assessed value. It was consistent enough that I’d share it with clients as a rough guide. Not a guarantee, but a reliable pattern.
I can’t say that anymore.
In 2009, after the financial crisis, the market had softened enough that homes were actually selling at 98% of assessed value — below assessment on average. The township’s numbers had gotten ahead of where buyers were willing to go.
Then the market recovered, and for years that 6-10% over assessment range held. It was a useful data point. It gave buyers and sellers a frame of reference.
Then the pandemic happened. By the time I ran it again in early 2024, that range had completely blown out. Single-family homes were selling at an average of 26% above assessed value. Condos and townhomes were at 22% above. The market had moved so fast that assessments couldn’t keep up, and the old rule of thumb had become meaningless.
Now here’s 2026:
- 95% of all homes sold above their assessed value
- Single-family homes sold at an average of 26% above assessed value
- Condos and townhomes sold at an average of 15% above assessed value — down from 22% last year
- Only 14 of 306 sales closed at or below assessed value
And within single-family homes, the gap widens as prices rise:
- Under $750K: sold at avg 124% of assessed value
- $750K — $1M: sold at avg 120% of assessed value
- $1M — $1.5M: sold at avg 124% of assessed value
- $1.5M and above: sold at avg 131% of assessed value
So this year, condos compressed — the gap narrowed from 22% to 15%. Single-family held roughly steady at 26%. Luxury widened further. None of those moves were predictable from the prior year’s data.
Why the Relationship Keeps Shifting
Bernards Township does annual reassessments and physically re-inspects properties on a four-year rotation. The goal — stated directly on the township’s website — is to have assessments reflect 100% of market value. And to their credit, they work at it more consistently than many NJ municipalities.
But the market doesn’t wait for the assessor. When prices move fast — as they did from 2020 through 2023 — assessments lag. When the market stabilizes or softens in certain segments, assessments can actually catch up or even overshoot in isolated cases. The relationship is always a moving target, and it moves differently depending on property type, neighborhood, price point, and when your home was last physically reviewed.
That’s why I can’t hand you a clean formula. The gap between assessed value and market value in Bernards Township right now is somewhere between 15% and 31% depending on what you own and where. That’s not a useful number for most decisions.
What Your Postcard Actually Tells You – And Doesn’t
Here’s what matters most when those postcards arrive:
Your assessment is not your tax bill. Your tax bill is determined by your assessed value multiplied by the tax rate — and the tax rate isn’t set until after the municipal budget is approved in spring. If assessments rose broadly across the township, the rate adjusts. Your taxes will likely go up, but not necessarily by the same percentage your assessment did.
Your assessment is not what your home will sell for. The data above makes that clear. Buyers don’t look at assessed value when they decide what to offer. They look at what comparable homes have actually sold for recently. Those are two very different numbers right now.Your assessment is not reliable for pricing your home. I’ve seen sellers anchor to their assessed value — either assuming it’s a floor or using it to justify a list price. Neither approach holds up in this market. Pricing has to be built from current comparable sales, not from a number the township assigned based on prior-year data.
If You Think Your Assessment Is Wrong
You have the right to appeal. In New Jersey the deadline to file a tax appeal is April 1st of the tax year. To have a strong case you need evidence that your assessed value exceeds your property’s actual market value — which is a harder argument to make for most homeowners right now, given how far sale prices have outpaced assessments across the board.
That said, if your home has specific condition issues, if there are errors in the township’s data about your property, or if the comparable sales in your immediate area tell a different story, it may be worth a conversation with a tax attorney or a call to the assessor’s office directly.
The Bottom Line
I’ve been running this analysis long enough to know that anyone who gives you a clean, confident answer about what Bernards Township assessments mean for market value is oversimplifying. The relationship is real but it’s not stable, it’s not uniform, and it changes every year.
What is stable: well-priced, well-prepared homes in Basking Ridge are selling fast and above asking. That has nothing to do with assessed value and everything to do with what buyers are willing to pay right now. If you want to know what your home is actually worth in today’s market, that’s a conversation built on current data — not a postcard.
If you have questions about what your assessment means for your specific situation, or you want to know what your home would realistically sell for today, reach out. I’m happy to walk you through it.
Frequently Asked Questions
Does the tax assessment determine what my home is worth in Basking Ridge?
No — and the gap between assessed value and actual market value in Bernards Township has been significant for several years. Based on the most recent 12 months of closed sales, single-family homes sold at an average of 26% above assessed value and condos and townhomes sold at an average of 15% above. Only 4.6% of homes sold at or below their assessed value. Buyers make offers based on comparable sales, not assessments.
Will my property taxes go up by the same percentage my assessment increased?
Almost certainly not. Your tax bill is your assessed value multiplied by the tax rate — and the tax rate is set after the municipal budget is approved each spring. If assessed values rose broadly across Bernards Township, the rate typically adjusts downward to some degree. The two numbers move together, which is why your tax increase is usually smaller than your assessment increase suggests.
How do Bernards Township tax assessments compare to sale prices in 2026?
Based on 306 closed sales over the past 12 months, 95% of homes in Bernards Township sold above their assessed value. The average gap is 21% for all property types combined — but it varies significantly: condos and townhomes average about 15% above assessment, while single-family homes average 26% above, and luxury homes over $1.5M average 31% above. The relationship has shifted considerably since 2009, when homes were selling at essentially 98% of assessed value
Can I use my tax assessment to price my home for sale in Basking Ridge?
No. Assessed value is not a reliable starting point for pricing strategy. The gap between assessed value and market value is significant and uneven across property types and price ranges. Pricing a home correctly in Basking Ridge requires a current comparable sales analysis — what similar homes have actually sold for recently in your specific neighborhood. That is what buyers are using, and it is what needs to drive your list price.
