Buy Your Next Massachusetts Home Before This One Sells
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
Two Massachusetts facts decide most move-up plans, and neither is about the mortgage. One is a tax threshold that moves every year. The other is a county line drawn across open water.
The line at $1,107,750
Massachusetts publishes it plainly. For tax year 2026, income exceeding $1,107,750 carries an additional surtax of 4%. The threshold was $1,083,150 for 2025 and $1,053,750 for 2024, so it has moved roughly $24,600 in the last year alone.
For most households that is a number about salaries. For someone selling a Massachusetts home held for decades, it can be a number about the sale. A capital gain that exceeds the federal exclusion flows into Massachusetts taxable income for that year, and a large enough gain can carry a household over the line.
We are lenders, not accountants, and we are not going to compute anyone's gain or tell anyone when to close. What we will do is say the number out loud, because buy-before-you-sell financing is repaid out of net proceeds and this comes out of the same pot. Take it to your CPA before you sequence the move. Detail on the surtax page.
Three loan limits in one state
Most states run two conforming limits at most. Massachusetts runs three.
| Limit | Where |
|---|---|
| $1,249,125 | Dukes County (Martha's Vineyard) and Nantucket County |
| $962,550 | Essex, Middlesex, Norfolk, Plymouth and Suffolk, the Boston metro |
| $832,750 | Barnstable (Cape Cod), Berkshire, Bristol, Franklin, Hampden, Hampshire, Worcester |
The middle tier is the unusual part. At $962,550 the Boston-metro counties sit $129,800 above the national baseline and $286,575 below the island limit, in a band most states never occupy.
And the bottom of that table contains Cape Cod. Barnstable County is at the national baseline while Dukes and Nantucket, a few miles across Nantucket Sound, carry the state's highest figure. The difference is $416,375 and it is decided by which metropolitan area the water puts you in. See the three tiers page.
Where the limits meet the prices
The comparison that matters is each county's limit against what homes there actually cost.
| Metro | Typical value, Aug 2026 | Limit | Headroom |
|---|---|---|---|
| Vineyard Haven | $1,557,691 | $1,249,125 | Over by $308,566 |
| Barnstable Town | $762,442 | $832,750 | $70,308 |
| Boston | $733,574 | $962,550 | $228,976 |
| Worcester | $479,429 | $832,750 | $353,321 |
On Martha's Vineyard the typical home is already $308,566 past the highest conforming limit Massachusetts offers. The median purchase there is a jumbo transaction, which changes how the departing residence gets treated. Cape Cod, with the lowest limit in that table, has about $70,308 of room and is rising 2.4% a year.
How Bay Staters buy first
| Structure | Works best when | Massachusetts note |
|---|---|---|
| Carry both, recast after | Income supports both payments | The recast is funded by net proceeds, so the surtax question sizes it |
| Borrow against current equity | Equity is strong, sale is near | Massachusetts has no constitutional cap on homestead liens, unlike Texas at 80% CLTV |
| Keep it and rent it | The departing home covers its own payment | No sale, so no gain realised this year, and no proceeds either |
That third row deserves a careful read rather than a quick one. Not selling means not realising the gain, which is a genuine consideration for a long-held Massachusetts home. It also means no proceeds to repay anything. Take the trade to your CPA. Structures compared on the structures page.
If you rent it out, the lease will not help you qualify
Fannie Mae Selling Guide B3-3.8-05, dated 09/02/2026 under Announcement SEL-2026-08, states that lease agreements are not permitted for any departing residence. Market rent comes from a full appraisal with market rents, a Form 1007 rent schedule, or market analysis tools with at least three comparable rentals.
The math is gross rent times 75%, less that property's PITIA, offsetting that payment only. Under 12 months of property management experience, six months of reserves on the vacated home apply. See the Form 1007 page.
Frequently asked questions
What is the Massachusetts surtax threshold for 2026?
mass.gov states that for tax year 2026, income exceeding $1,107,750 carries an additional surtax of 4%. The threshold was $1,083,150 for tax year 2025 and $1,053,750 for 2024.
Can selling my Massachusetts home trigger the 4% surtax?
It can. A capital gain above the federal exclusion flows into Massachusetts taxable income for the year of the sale, and a large enough gain on a long-held home can carry a household over the threshold. Whether it reaches you depends entirely on your facts, which is a question for your CPA.
Does it matter which tax year my Massachusetts sale closes in?
The threshold applies per tax year, so the year of closing determines which year's income the gain lands in and which threshold applies. We flag that it matters; your CPA should decide what to do about it.
How many conforming loan limits does Massachusetts have?
Three for 2026: $1,249,125 in Dukes and Nantucket counties, $962,550 in the five Boston-metro counties of Essex, Middlesex, Norfolk, Plymouth and Suffolk, and $832,750 in the remaining seven including Barnstable.
Is Cape Cod a high-cost county for loan limits?
No. Barnstable County sits at the $832,750 national baseline, while Dukes and Nantucket across Nantucket Sound carry $1,249,125. The gap is $416,375 and it follows the metropolitan area rather than local prices.
Is a typical Martha's Vineyard purchase a jumbo loan?
Yes. Vineyard Haven's typical home value was $1,557,691 in August 2026 against the $1,249,125 limit that applies in Dukes County, so the median home sits $308,566 above the highest conforming limit in the state.
What is the conforming loan limit in Boston for 2026?
$962,550 on one unit across Essex, Middlesex, Norfolk, Plymouth and Suffolk counties. That is a middle tier, $129,800 above the national baseline and $286,575 below the island limit.
Can I use a lease to qualify with rental income from the home I am leaving?
No. Fannie Mae Selling Guide B3-3.8-05, dated 09/02/2026, states that lease agreements are not permitted for any departing residence. Market rent is documented by a complete appraisal including market rents, a Form 1007 rent schedule, or market analysis tools with at least three comparable rentals.
