Everything a New Jersey homeowner needs before making an offer, starting with the fee most people still think somebody else is paying.

One: find out what the sale actually nets you

New Jersey's seller carries two fees. The Realty Transfer Fee on a graduated per-$500 schedule, and above $1,000,000 of consideration the Graduated Percent Fee on top, beginning at 1% of total consideration.

The New Jersey Division of Taxation states that the seller is statutorily responsible for both. The older description of a flat 1% "mansion tax" paid by the buyer is outdated, and it is still repeated widely enough that move-up sellers routinely under-budget this. See the seller-pays page and the net proceeds page.

Two: check which limit applies where you are buying

New Jersey's 2026 one-unit conforming limit is $1,209,750 in twelve 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, containing Princeton and Trenton, is at the baseline, $377,000 below adjacent Middlesex and Hunterdon. So is Warren County, beside Sussex and Hunterdon. The line follows the metropolitan area. See the jumbo page.

Three: pick the structure against that net number

Carry both and recast, borrow against the departing home's equity, or keep it and rent it. Two of the three are repaid from net proceeds; the third avoids the transfer fees entirely because no deed is recorded. The structures page compares them.

The rental-income rules changed in September 2026

Fannie Mae Selling Guide B3-3.8-05, dated 09/02/2026 under Announcement SEL-2026-08:

A primary residence being vacated and converted to an investment property when the borrower buys a new primary residence is eligible.
The lender must document a current housing payment to use any departing-residence rental income.
Documentation is a complete appraisal with market rents, a Form 1007 rent schedule, or market analysis tools with at least three comparable rentals from the same market area where possible.
Lease agreements are not permitted for any departing residence.
Adjusted net rental income is gross rent times 75% less that property's PITIA. Positive offsets that PITIA only; negative is added to the debt-to-income ratio.
Six months of reserves for the vacated property's PITIA under 12 months of property management experience.

Frequently asked questions

What should a New Jersey homeowner check first before buying the next house?

What the sale of the current home actually nets. New Jersey's seller carries the Realty Transfer Fee on a graduated schedule and, above $1,000,000 of consideration, the Graduated Percent Fee on top, and the Division of Taxation states the seller is statutorily responsible for both.

What are the 2026 conforming loan limits in New Jersey?

$1,209,750 on one unit in Bergen, Essex, Hudson, Hunterdon, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex and Union. The other nine counties, Atlantic, Cape May, Burlington, Camden, Gloucester, Salem, Cumberland, Mercer and Warren, are at $832,750.

Why is Mercer County at the baseline loan limit?

Because conforming limits follow the metropolitan statistical area a county sits in rather than local prices. Mercer is in the Trenton area and receives the $832,750 baseline, $377,000 below adjacent Middlesex and Hunterdon in the New York metro at $1,209,750.

Did the rules for using rental income from a departing residence change?

Yes. Fannie Mae Selling Guide B3-3.8-05 is dated 09/02/2026 under Announcement SEL-2026-08. Lease agreements are no longer permitted for any departing residence, qualifying income is gross rent times 75% less that property's PITIA as an offset only, and six months of reserves apply under 12 months of property management experience.
