Illinois is one of the few big states where flip math still works on paper. Over the 12 months ending July 2026, Illinois investors flipped about 11,892 homes for an average gross profit of roughly $97,000 and a 45.5% gross ROI, more than double the national typical margin, while the statewide median price climbed 6.0% to $338,000 on shrinking inventory. The catch is the carrying cost: Illinois has some of the highest property taxes in the country, and Chicago stacks a hefty transfer tax on every sale.
Here's where the spread is and what will eat into it.
Illinois 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)
- Illinois flips: about 11,892 flips in the 12 months to July 2026, with a 45.5% average gross ROI, about $97,000 average gross profit and a 174-day average hold (BatchData)
- Statewide median price: $338,000 in July 2026, up 6.0% from $319,000 a year earlier, with closed sales up 0.8% to 13,503 (Illinois Realtors)
- Inventory: 22,363 homes for sale statewide in July, 4.7% fewer than a year earlier; in the nine-county Chicago metro, listings fell 11.9% (Illinois Realtors)
- Property tax: about a 2.07% effective rate, second highest in the US behind New Jersey (Chicago Agent, citing Rocket Mortgage)
- Transfer tax: a state tax of $0.50 per $500, usually paid by the seller, plus county and city taxes that push a Chicago sale far higher (Clever)
Why Illinois Flips Still Pencil Out
Two things set Illinois apart from the Sun Belt in 2026: prices are still rising, and there aren't enough homes for sale.
- Appreciation hasn't stalled. The statewide median was up 6% in July and the Chicago metro median hit $401,000, up 6.8%. Redfin had Chicago-area prices up 7.7% year over year in June, one of the biggest gains among the 50 largest metros. A flip that buys right gets a little tailwind on the exit, which Texas and Florida flippers don't have.
- Supply is tight. Chicago-area listings are down double digits year over year. Buyers who want a move-in-ready older house have few choices, and that's exactly what a flip sells.
- Cheap downstate entry points. Peoria showed up on ATTOM's Q1 2026 list of top-return metros with a $80,000 typical purchase, $142,500 resale and a 78.1% gross ROI.
Remember these are gross returns, before rehab, financing, property taxes and selling costs. And a 174-day average hold is long in a state where every month of ownership carries a 2% annual tax bill.
Where to Flip in Illinois: Metro by Metro
Figures come from different sources and periods, so treat them as a starting point and pull comps for the block you're bidding on.
Chicago Metro
Chicago and its suburbs are where most of the volume is. The nine-county metro sold 9,108 homes in July at a $401,000 median, up 6.8%, with listings down 11.9% to 13,970. Older bungalows, two-flats and suburban ranches renovated properly sell into a thin field of competition. The city itself has the steepest transfer taxes and its own contractor licensing, so many investors find cleaner math in inner-ring suburbs.
Rockford
Rockford was one of the fastest-appreciating markets in the state early this year, with a Redfin Q1 2026 median of $214,583, up 11.3% year over year. But July closed sales in the metro fell 40.3% to 218, so check how many comparable homes are actually trading before you count on a quick exit.
Peoria
Peoria is the low-cost, high-return play. Redfin put the metro's first-half 2026 median at $170,703, up 8.0%, with active listings up 4.1% to 1,206, and July sales rose 5.7% to 497. Big percentage returns on small dollars mean your rehab budget has to be tight; an over-improved Peoria house is hard to sell.
Springfield and Champaign-Urbana
Springfield and Champaign-Urbana are steady, government- and university-anchored markets. Both saw fewer July closings, with Springfield down 9.2% to 256 sales and Champaign-Urbana down 5.9% to 269.

What an Illinois Flip Costs in 2026
- Financing: Hard money generally runs about 9.5% to 13% interest plus 1.5 to 3 points, and your resale buyer is looking at a 30-year mortgage around 6.7%.
- Property taxes: This is the big one. At roughly 2% of value, a six-month hold on a $300,000 flip costs about $3,000 in taxes alone. Chicago's median residential bill jumped 16.7% to $4,457 for 2024 taxes before rising a more modest 2.2% for 2025, and Illinois bills are paid in arrears, so read the proration on your closing statement carefully.
- Insurance: Illinois premiums average about $3,240 a year for a $400,000 dwelling policy, 30% above the national average, and Illinois trailed only Texas for hail damage claims in 2024. Price a vacant or builder's risk policy before you close, and watch for separate wind and hail deductibles.
- Transfer tax: The state charges $1 per $1,000, and Cook County adds its own. Chicago's city tax is far larger: one guide estimates total transfer taxes top $6,000 on a $400,000 Chicago sale versus about $600 in DuPage County. Sources quote the city rate differently, so get the exact figure from your title company.

Illinois Rules Flippers Should Know
- Wholesaling is capped without a license. Since a 2019 amendment to the Real Estate License Act, marketing contracts you don't own on two or more occasions in 12 months counts as brokerage and requires a license, with fines up to $25,000 (REjournals).
- Contractor licensing is local, except roofing. Illinois has no statewide general contractor license, but roofers need a state IDFPR license, and Chicago requires its own general contractor license for most construction work (ServiceTitan). Pull permits in the municipality where the house sits.
- Check the reassessment calendar. Cook County reassesses one third of the county each year; the south and west suburbs are up in the 2026 cycle and the city in 2027 (Sun-Times). A reassessment can change the tax bill your buyer sees, and therefore what they can afford.
2026 Outlook for Flipping Houses in Illinois
Illinois is set to stay a seller's market into late 2026. DePaul's Institute for Housing Studies projected Illinois closed sales for August through October roughly flat and October single-family prices about 5.5% higher than a year earlier. That's a better backdrop than most of the country. The risk isn't the exit price; it's the holding cost. Flippers who move fast, keep rehabs tight and budget honestly for Illinois property taxes should keep finding margin, especially in suburban Chicago and the cheaper downstate metros.
Key Takeaways
- Illinois flips average about a 45.5% gross ROI and $97,000 gross profit, more than double the national typical margin.
- Prices are up about 6% statewide and inventory is shrinking, especially around Chicago.
- Property taxes near 2% a year and a 174-day average hold make speed worth real money.
- Chicago transfer taxes can run 10 times a suburban sale's; check the parcel before you bid.
- Don't wholesale more than one contract a year without a license.
Frequently Asked Questions
Is flipping houses in Illinois profitable in 2026?
Yes, more than in most states. BatchData puts the average Illinois flip at a 45.5% gross ROI over the 12 months to July 2026, and prices are still rising, but high property taxes mean net profit depends on a short hold.
What is the best city to flip houses in Illinois?
The Chicago suburbs have the deepest buyer pool and rising prices. For bigger percentage returns on smaller checks, Peoria posted one of the highest gross ROIs in the country in Q1 2026, though the dollar profits are smaller.
Do you need a license to wholesale houses in Illinois?
You can do one wholesale deal in a 12-month period without a license. A second one counts as brokerage under the Real Estate License Act, so regular wholesalers need a broker license or a licensed partner.
How much does it cost to flip a house in Illinois?
On top of the purchase and rehab, plan for hard money around 9.5% to 13% plus points, property taxes near 2% a year, insurance above the national average, and transfer taxes that are small statewide but significant in Chicago.
