Buy Your Next New Jersey Home Before This One Sells
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
If you are planning a New Jersey move-up around the idea that the buyer pays the mansion tax, the plan has a hole in it. The State says the seller is responsible, and the fee is graduated now.
Start with the correction
New Jersey's fee on higher-value homes is widely described as a flat 1% "mansion tax" paid by the buyer. That is not what the New Jersey Division of Taxation currently publishes.
The State imposes a Graduated Percent Fee as a supplemental fee to the Realty Transfer Fee, on the recording of the deed for the sale of real property where the consideration paid is more than $1,000,000. The rates are graduated by total consideration. And the Division's page says, in those words, that the seller is statutorily responsible for the RTF and the Graduated Percent Fee.
For someone buying a first home over a million dollars, that is welcome news. For someone selling a New Jersey home over a million dollars in order to buy the next one, it is a line item that used to belong to the other side of the table. Full detail on the seller-pays page.
The brackets
| Total consideration | Graduated Percent Fee |
|---|---|
| over $1,000,000, not over $2,000,000 | 1% |
| over $2,000,000, not over $2,500,000 | 2% |
| over $2,500,000, not over $3,000,000 | 2.5% |
| over $3,000,000, not over $3,500,000 | 3% |
| over $3,500,000 | 3.5% |
It applies where the land conveyed is Class 2 residential, Class 3A farm containing a building suited for residential use, Class 4A commercial other than industrial or apartment, or Class 4C cooperative units. Form RTF-1EE must be annexed to every deed for consideration over $1,000,000.
Why a lender is telling you about a transfer fee
Because buy-before-you-sell financing is repaid out of the net proceeds of the departing home. Whatever comes off the top of that sale is money not available to retire a bridge loan or fund a recast on the new mortgage.
In New Jersey the seller carries the Realty Transfer Fee on a graduated schedule, and above $1,000,000 carries the Graduated Percent Fee on top. Plan the overlap on net proceeds rather than sale price. See the net proceeds page.
How New Jerseyans buy first
| Structure | Works best when | New Jersey note |
|---|---|---|
| Carry both, recast after | Income supports both payments | The recast is funded by net proceeds, so the seller-side fees size it |
| Borrow against current equity | Equity is strong, sale is near | New Jersey has no constitutional cap on homestead liens, so this is available |
| Keep it and rent it | The departing home covers its own payment | No sale, so no transfer fees, and no payoff either |
The third row is worth pausing on. Keeping the home avoids the seller-side fees entirely, because there is no deed to record. That does not make it the right answer, but in New Jersey it is a larger thumb on the scale than elsewhere. Compare them on the structures page.
Twelve counties at one limit, nine at another
New Jersey's 2026 one-unit conforming limit is $1,209,750 in the twelve New York metro counties: Bergen, Essex, Hudson, Hunterdon, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex and Union. The other nine are at $832,750: Atlantic, Cape May, Burlington, Camden, Gloucester, Salem, Cumberland, Mercer and Warren.
Mercer County contains Princeton and Trenton and sits at the baseline, $377,000 below neighbouring Middlesex and Hunterdon. The line follows the metropolitan area, not price or prestige. See the jumbo page.
And one market is about to outgrow its own ceiling
Ocean City sits in Cape May County, a baseline county with an $832,750 limit. Its typical home value in August 2026 was $806,261, rising 9.3% year over year, the fastest in this build round. That leaves roughly $26,000 of headroom on a market moving at nearly ten percent.
If you are planning an Ocean City move-up, the conforming question is live now rather than theoretical. See the Ocean City page and the move-up market 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
Who pays the mansion tax in New Jersey?
The seller. The New Jersey Division of Taxation states that the seller is statutorily responsible for the Realty Transfer Fee and the Graduated Percent Fee. The older description of a flat 1% fee paid by the buyer is outdated.
Is New Jersey's mansion tax still a flat 1%?
No. The State imposes a Graduated Percent Fee on consideration over $1,000,000: 1% over $1,000,000 but not over $2,000,000; 2% over $2,000,000 but not over $2,500,000; 2.5% over $2,500,000 but not over $3,000,000; 3% over $3,000,000 but not over $3,500,000; and 3.5% above $3,500,000.
Which properties does the Graduated Percent Fee apply to?
Deeds where the land conveyed is Class 2 residential; Class 3A farm, but only where the farmland contains a building or structure intended or suited for residential use; Class 4A commercial other than industrial or apartment; and Class 4C cooperative units.
Why does a mortgage site care about a transfer fee?
Because buy-before-you-sell financing is repaid from the net proceeds of the departing home. Seller-side fees reduce those proceeds, which reduces what is available to retire a bridge loan or fund a recast on the new mortgage.
What are the 2026 conforming loan limits in New Jersey?
$1,209,750 on one unit in the twelve New York metro counties: Bergen, Essex, Hudson, Hunterdon, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex and Union. The other nine counties, including Mercer, Cape May and Atlantic, are at $832,750.
Is Princeton in a high-cost county for loan limits?
No. Princeton is in Mercer County, which sits at the $832,750 baseline, $377,000 below adjacent Middlesex and Hunterdon counties at $1,209,750. Conforming limits follow the metropolitan area rather than local prices.
Which New Jersey market is rising fastest?
Ocean City, up 9.3% year over year as of August 2026 to a typical home value of $806,261. That sits about $26,000 under Cape May County's $832,750 conforming ceiling.
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.
