Delaware's typical home value is about $406,000, up just 1.3% over the past year, so appreciation won't carry a flip here in 2026. What will make or break your deal is a cost most states don't have at this size: a realty transfer tax of up to 4% of the price, usually split between buyer and seller, which a flipper ends up paying on both the purchase and the sale.
Here's what the numbers say about flipping houses in Delaware in 2026, county by county, and how to underwrite around the costs.
Delaware 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)
- Regional flip margin: the Philadelphia metro, which includes Wilmington and New Castle County, posted a 62.8% typical gross margin in Q2 2026, fifth best among large US metros (MPA)
- Home values: about $406,074 statewide in August 2026, up 1.3% year over year (Zillow)
- By county: typical values of about $490,900 in Sussex, $374,900 in Kent, and a $323,467 median sale price in New Castle through June (Zillow)
- Inventory: active listings rose roughly 28% in 2025 and months of supply went from 2.8 to nearly 4 in Sussex and New Castle (2025 Year in Review)
- Transfer tax: 4% combined in New Castle County and 3.5% in Kent and Sussex, customarily split 50/50 (Clever)
Why Delaware Flips Live or Die on Transaction Costs
Most flippers budget transfer taxes as a rounding error. In Delaware you can't. If you pay half of a 4% tax when you buy and half again when you sell, that's roughly 4% of value gone to the state and county before rehab, interest or commissions. On a $350,000 resale, that's around $14,000.
Meanwhile, prices are barely moving. Statewide values are up about 1.3% a year, and Sussex and Kent medians were down 4.1% and 2.8% year over year in October 2025. So the spread has to come from buying well below value and adding real value, not from the market.
Two forces help:
- Northern Delaware rides Philadelphia's flip economics. The Philadelphia metro's 62.8% gross margin is among the best in the country. Older rowhomes and twins are the classic buy-cheap, renovate, resell play there, and Wilmington has a lot of the same kind of housing.
- More inventory means more negotiating room. With supply near four months in parts of the state, sellers of dated homes have to compete, and that's where flippers find discounts.
Where to Flip in Delaware: Metro by Metro
Delaware's three counties are three different markets. Median figures vary by source, so treat them as a starting point and pull street-level comps.
Wilmington
Wilmington is the state's most flip-friendly market on paper. Redfin data put its median price around $275,000 in May 2026, flat year over year, with about 3.2 months of supply, a balanced market. Older city housing is the closest thing Delaware has to Philadelphia's rowhome flips. Expect neighborhood-by-neighborhood swings, so underwrite each block separately.
Newark and New Castle County
Newark and the surrounding New Castle County suburbs offer a deeper, more stable buyer pool. The county's median sale price was about $323,467 through June 2026, with values up 2.1% and 1,242 homes for sale. The University of Delaware keeps rental demand high around Newark, which gives you a second exit if a flip doesn't sell. Watch property taxes closely here: New Castle County is still working through the fallout of its reassessment.
Dover and Kent County
Dover and Kent County are the most affordable part of the state, with a typical value near $374,900. Kent's median slipped 2.8% year over year in October 2025, so this is a market for buying cheap and keeping rehab scope tight. Kent's lower 3.5% transfer tax rate also helps the math versus New Castle.
Lewes and the Sussex Beaches
Lewes, Rehoboth and the rest of coastal Sussex are the high-price end, with a county typical value around $490,900. Sussex's median was down 4.1% year over year in October 2025 as inventory built. Bigger price points mean bigger dollar spreads, but also a seasonal, second-home buyer pool and a lot of new construction competing for the same buyer. Time your listing for spring.

What a Delaware Flip Costs in 2026
- Financing: Fix-and-flip loans for experienced borrowers run about 9% to 12% plus 1.5 to 3 points, and your resale buyer faces a 30-year mortgage around 6.7%.
- Transfer tax: The state takes 2.5% and counties or towns typically add 1.5% (HomeLight). Split 50/50, budget about 2% on your purchase and 2% on your sale. In a slow market, sellers sometimes agree to cover the buyer's half, which can cost you more on the exit.
- Possible relief: HB 286 would exempt sales under $350,000 from the state's 2.5% share and cut the total rate to 3% on homes from $350,000 to $500,000, phased in from January 2027, but as of June 2026 it was still working through House committees (House GOP). Don't underwrite to it until it passes.
- Property taxes: Delaware's statewide reassessment rewrote tax bills. New Castle County's assessed values rose an average 433% in the first reassessment since 1987, and 2026 bills are now due December 31 rather than September 30 (New Castle County). Check the current bill on any property you buy rather than trusting an old listing.
- Selling costs: Add agent commissions, title and settlement fees on top of your share of the transfer tax.

Delaware Rules Flippers Should Know
- Wholesaling now needs a real estate license. SB 201 treats wholesaling (contracting to buy and assigning the contract for a fee) as a licensed real estate activity, gives existing wholesalers 270 days to get licensed and adds a 21-day right to cancel a wholesale agreement (Plural Policy). It appears in Delaware's session laws as 85 Del. Laws c. 274; confirm the effective date before your next assignment.
- Transfer tax is a closing-table negotiation. The 50/50 split is custom, not law, so read the contract and know who's paying on both ends of your flip (HomeLight).
- Reassessments can still move. The House passed bills in June 2026 to address problems with the statewide reassessment (House Democrats), including a bill letting school districts reset their 2026-27 rates. Factor the current tax bill into your hold cost.
2026 Outlook for Flipping Houses in Delaware
Expect flat prices, rising inventory and transaction costs that stay high unless HB 286 is revived. That's a market that rewards experienced flippers who buy at a real discount and punishes thin cosmetic flips. Northern Delaware, especially Wilmington's older housing stock, looks like the best opportunity, sharing in some of Philadelphia's strong flip margins. Sussex offers bigger dollar spreads but more seasonal and new-construction risk.
