New Jersey flips are big-ticket deals. Over the 12 months to July 2026, the average Garden State flip made about $167,000 in gross profit on a 47.9% gross ROI, close to double the national average. The catch is what comes out of that spread: the highest property taxes in the country, a transfer fee that now lands on sellers at the high end, and six-month holds.
Here's what the 2026 numbers say about where to flip in New Jersey and what it costs.
New Jersey House Flipping in 2026 at a Glance
- National flip margin: 21.5% typical gross ROI and $60,526 typical gross profit in Q2 2026, down from 27.6% and $71,000 a year earlier (ATTOM)
- New Jersey flips: 8,043 flips in the 12 months to July 2026, 17th among states, with a 47.9% average gross ROI, about $167,000 average gross profit and 182 days to flip (BatchData)
- Statewide median price: $610,000 for single-family homes year to date through July, up 3.7%, with closed sales flat (NJ Realtors via Insider NJ)
- Inventory: 21,637 homes for sale in July, up 5.9% year over year (Insider NJ)
- Property tax: the highest effective rate in the US, about 2% depending on the source, and the highest average tax bills (ROI-NJ)
- Transfer costs: sellers pay the realty transfer fee, and since July 2025 also a mansion tax of 1% to 3.5% on sales over $1 million (Troutman Pepper)
Why New Jersey Flips Pay More but Cost More
BatchData's gross ROI compares purchase and resale prices, before renovation, financing, taxes and selling costs. A 47.9% gross return on a New Jersey flip leaves real room for a renovation budget, which is why investors keep working here even as profits shrink nationally to 21.5% in Q2.
Three things hold that spread up, and two pull it down:
- Tight supply. Even after a year of growth, inventory is thin, and single-family months of supply in North Jersey markets like Bergen County was 2.6 in July. Renovated homes still sell.
- Old housing stock. Much of the state's inventory is decades old, so a well-done renovation adds real value against dated comps.
- Rising prices. Single-family medians are still climbing about 4% a year statewide, with some markets much faster.
- Holding costs. At roughly 182 days per flip, you'll carry two quarters of the country's heaviest property taxes.
- Bigger checks. A $167,000 average profit comes with a much larger purchase and rehab budget, and a mistake costs proportionally more.
Where to Flip in New Jersey: Metro by Metro
Figures come from different sources and periods, so treat them as a starting point and pull comps for the block.
Newark and Essex County
Newark has been one of the state's fastest-rising markets. A HousingWire analysis found its median listing price up 7.66% to $492,500 through April 2026, with listings averaging 56 days on market and 14.6% taking a price cut. Zillow's home value index is flatter, so underwrite to closed comps. Multifamily conversions and two- to three-family homes are the classic Newark flip.
Bergen County and North Jersey
Bergen County is the high end. Its single-family median hit $949,500 in July, up 8.5%, with 2.6 months of supply. Strong demand and commuter access to Manhattan support resale, but many flips here will cross $1 million, where the seller now pays the mansion tax on top of the transfer fee.
Trenton and Mercer County
Trenton is a mid-priced market with more room to negotiate. Redfin metro data puts its first-half 2026 median at $458,637, up 6.1%, with active listings up 7.1% and 3.4 months of supply. The metro includes pricier Princeton-area towns, so the city itself trades well below that figure.
South Jersey: Camden County and the Shore
Camden County is the affordable side of the state, with a July 2026 single-family median around $424,218, in the Philadelphia metro where Q1 2026 flip margins were a strong 62%. Down the Shore, Atlantic City prices rose 10.9% to $379,980 in Q1 2026. Shore flips need extra diligence on flood zones and seasonal demand.

What a New Jersey Flip Costs in 2026
- Financing: Hard money runs about 9.5% to 13% plus 1.5 to 3 points (Crestmont Capital); your buyer faces a 30-year rate around 6.7%.
- Property taxes: Estimates of the effective rate range from about 1.9% to 2.4% depending on the source, and ATTOM put New Jersey's average bill at $10,499 for 2025, the nation's highest. Check the actual bill for the address; rates swing widely town to town.
- Transfer fee and mansion tax: Sellers pay the realty transfer fee, roughly 1% at typical flip prices (NJ Realtors). For deeds recorded since July 10, 2025, sellers also pay a mansion tax on the entire price: 1% from $1 million to $2 million, rising to 3.5% above $3.5 million (Troutman Pepper). A flip that resells for $2.1 million pays 2% of the full price, so price your exit around the brackets.
- Insurance: Standard policies are manageable inland, but vacant-property coverage costs more, and Shore and riverfront flips may need flood insurance that changes your buyer's math.
- Selling costs: Agent commissions plus attorney fees, since lawyers commonly review New Jersey contracts.

New Jersey Rules Flippers Should Know
- Wholesaling licensing is on the table. Assembly Bill A4278 would require a real estate license to wholesale one- to four-family homes; it was pending in the 2026-2027 session (Legiplex). Until something passes, assign contracts carefully and disclose your interest.
- Investor taxes are being proposed. S1516, the End Hedge Fund Control of New Jersey Homes Act, introduced January 2026, would tax certain entity purchases of one- to four-family homes, with exemptions for smaller owners (Legiplex). It's a bill, not law; watch it if you buy through an LLC at scale.
- Consumer fraud exposure may expand. S2147 would bring sales by homeowners under the Consumer Fraud Act, raising the stakes for concealing defects in a renovated home (LegiScan). Pull permits and document your work either way.
2026 Outlook for Flipping Houses in New Jersey
Prices are still rising about 4% statewide, inventory is growing slowly from very low levels, and New Jersey flips continue to earn more than double the national gross return. Expect the rest of 2026 to stay favorable for flippers who buy older homes below market in mid-priced towns, while the high end gets tougher with the seller-paid mansion tax. The main risk isn't the market; it's Trenton, where several investor bills are pending.
