Can You Still Flip Houses in St. Louis With 7% Rates?

Written by House Sold Easy Team

If you flip houses in St. Louis, September probably felt like the month the math got a little meaner. Mortgage rates crossed 7% again, more sellers started cutting prices, and the gap between a house that sells in a week and a house that sits for two months got wider.

None of that means flipping in St. Louis is over. It means the sloppy version of flipping is over. The deals still exist in St. Louis City, St. Louis County, and St. Charles County. You just have to buy tighter, renovate smarter, and price your resale like you actually want it to sell.

Below, we'll walk through what the numbers look like right now, from acquisition and rehab budgets to resale timing, financing costs, Missouri's capital gains change, and which St. Louis neighborhoods are worth your time this fall. We'll keep it practical and local, with links to the September 2026 reports we pulled the numbers from so you can check them yourself.

St. Louis Flipping Snapshot: Still Profitable, But Margins Are Tightening

Let's start with the honest picture. Flipping in Missouri is still making money, but less of it than a year ago. According to ATTOM's Q1 2026 state data, as broken down in a September 26 St. Louis investor analysis, Missouri recorded 1,404 flips with a typical gross profit near $39,838, while gross ROI slipped to 17.7% from 21.0% a year earlier.

That "gross" part matters. ATTOM measures the difference between what an investor paid and what they sold for. It doesn't subtract rehab, loan interest, holding costs, or commissions. So a 17.7% gross return in Missouri can shrink fast once you add real-world expenses.

Nationally, the trend has been similar. ATTOM's Q1 2026 report showed the typical national flip margin ticking up to 25.4%, the first improvement after seven straight quarters of decline, but still below where it was a year before. Flipping hasn't collapsed. It has matured.

Here's the part that works in St. Louis's favor, though. ATTOM found the strongest national margins came from homes bought between $100,000 and $200,000, while homes bought for under $50,000 tended to lose money. That $100K–$200K window describes a huge share of the brick single-family homes in South City and North County. The ultra-cheap, structurally rough house often isn't the bargain it looks like. The solid-but-dated house often is.

The resale side is also healthy if you're realistic. The St. Louis MSA posted an August 2026 median sold price of $305,000, up about 6.09% from a year earlier. Buyers are still out there. They're just pickier about condition and price than they were in 2022.

Acquisition Strategy: Targeting the 17.9% With Price Cuts

Your profit on a flip is made when you buy. That was always true, but at 7% money, it's the whole game. The good news is that more St. Louis sellers are willing to negotiate right now.

Our September 2026 outlook found that 17.9% of active listings across the St. Louis metro had taken at least one price reduction, with the rate running higher in pockets that have more older, non-updated homes. In that same data, St. Louis City listings with price cuts ran at 19.2% and St. Louis County at 17.4%.

North County is a good example. In Florissant and Hazelwood, inventory has been piling up faster and marketing times have stretched to roughly 35 to 45 days, which gives buyers more room on repair credits and price. For a flipper, that's exactly the kind of seller fatigue you want to find.

Inventory is also up across the board. St. Louis REALTORS® and MARIS figures published in early September put active regional inventory at 5,850 homes, about 15.2% higher than last year. More listings means more choices for you, but it also means more competition when you resell. Keep both sides in mind.

A simple price-cut pipeline

Here's a workflow a lot of St. Louis flippers use to turn price-cut data into actual offers:

1. Pull every active listing in your target zip codes that has at least one price reduction.
2. Log the original price, current price, reduction percentage, days on market, estimated repairs, and your conservative ARV.
3. Run your maximum allowable offer (more on that below) for each one.
4. Cross off anything where the current list price is already above your max number. Don't negotiate yourself into a bad deal.
5. For the rest, lead with a clean, numbers-backed offer and a fast close. Tired sellers often care more about certainty than squeezing out the last dollar.

Listings that have sat 30 days or more are usually where the room is. Many of them aren't broken houses. They're houses with a bad first price, weak photos, or cosmetic issues a flipper can fix quickly.

Renovation Costs in Missouri: What to Budget in 2026

Rehab budgets are where a lot of St. Louis flips quietly go sideways. The housing stock here is old, a lot of it is brick, and the surprises tend to be expensive ones.

A realistic starting range for the city's entry-level flips: one 2026 St. Louis flipping guide puts typical entry-level deals at $50,000–$90,000 purchase, $45,000–$70,000 in rehab, and ARVs around $180,000–$280,000. Cosmetic-plus flips in better condition can come in lower, but plan on the middle of that range if the house has been sitting vacant or was a long-term rental.

For bigger-picture context, ATTOM notes that experienced flippers typically estimate rehab and related costs at 20% to 33% of a property's after-repair value. On a $240,000 ARV, that's $48,000 to $79,000 in total spend beyond the purchase price. If your numbers only work with a $25,000 rehab on a house that needs a roof and a panel, the numbers don't work.

Material prices aren't helping either. A September 23, 2026 housing update reported that nearly 73% of homebuilders are paying more for materials than a year ago, with some seeing increases of up to 15% tied to tariffs. Flippers buy a lot of the same lumber, drywall, fixtures, and HVAC equipment, so pad your line items accordingly.

St. Louis-specific repairs to budget for first

Spend where an inspector will look first. In St. Louis, that usually means:

• Sewer laterals. Older neighborhoods like University City, Maplewood, and South City are known for them. A camera scope before you list helps you avoid ugly repair negotiations at closing. Honestly, scope it before you buy.
• Roof and tuckpointing. Brick is durable, but mortar isn't forever. Buyers and inspectors will spot failing joints.
• Electrical. Old panels and knob-and-tube still turn up in 1920s and 1940s homes.
• Plumbing and HVAC. Boilers, galvanized supply lines, and tired furnaces are common line items.
• Municipal occupancy inspections. St. Louis County has dozens of municipalities with their own inspection rules. Know the requirements before you close, not after you list.

Timeline-wise, plan for two to three months of rehab on a typical cosmetic-plus flip, and build extra time in if you're opening walls. As we'll see below, every extra month costs real money at today's rates.

The 70% Rule Still Applies, But Adjust for Current Rates

The classic 70% rule says your maximum allowable offer (MAO) should be 70% of ARV minus repairs:

It's still a useful first filter. The problem is that it was built for a world where money was cheaper, and houses sold faster. That 30% cushion is supposed to cover financing, holding costs, selling costs, and your profit. At 10%+ hard money, it doesn't stretch as far.

Here's a real-world St. Louis example. Using a $260,000 ARV and a $50,000 rehab, a local investor analysis found the 70% rule points to a $132,000 max offer, but once interest, points, buying costs, selling costs, and holding costs were added line by line, those expenses came to roughly $40,000, leaving about $37,000 in profit, or around 14% of ARV.

That's a decent deal. But look at how quickly it erodes. In that same example, each extra month of holding costs about $2,000, an 11-month hold drops profit to around $29,000, and an ARV that comes in $15,000 short cuts profit to about $23,000. That's under 9% of ARV for all that work and risk.

How to adjust the formula this fall

• Build out every cost. Instead of stopping at 70%, calculate interest, points, buying costs, selling costs, and monthly holding costs individually, then subtract the profit you actually need.
• Add a contingency. Put 15–20% on top of your contractor's estimate. Old St. Louis houses almost always find a way to use it.
• Discount long-DOM properties. If comparable homes in the area are sitting, trim your ARV by about 5% or assume a longer hold.
• Underwrite at 7%+ as a floor. Even if you're paying cash, underwrite your resale buyer's financing at today's rates, because that's what determines what they can pay you.
• Stress-test the timeline. Add two to three months and see if the deal still makes sense.

If a deal only works on the aggressive version of the math, pass. There will be another one.

Resale Strategy: Pricing to the First Two Weeks

St. Louis is running what we've been calling a two-speed market. Updated, move-in-ready homes in strong areas are going under contract in 4 to 7 days, while dated or overpriced listings are sitting for 44 days or more. Your finished flip needs to land in that first group.

The average still looks fast on paper. Redfin shows St. Louis homes selling in about 21 days on average over the three months ending August, at a median price around $260,000 and roughly $170 per square foot. But averages hide a lot. The flip with gray LVP and a builder-grade kitchen on a street that doesn't support a $280,000 price is the one that sits.

Pricing is where flippers get into trouble. Showing activity is highest in a listing's first 14 days, and homes that go 21 days without an offer tend to lose momentum, which often ends in a lower final price than a realistic starting number would have gotten.

A resale game plan

• Price off closed comps from the last 60–90 days, in the same school district and ideally within a few blocks, with a similar finish level. Ignore active list prices.
• Don't use the highest comp as your ARV. Use the middle of the realistic range.
• Set your adjustment trigger before you list. If you get fewer than 4 showings and no offers in 14 to 21 days, a planned 3–5% cut resets the listing in buyers' search alerts, which works better than a string of small, nervous reductions.
• Offer a rate buydown instead of a bigger price cut. At 7%, a seller-paid 2-1 buydown can do more for a buyer's monthly payment than knocking a few thousand off the price.

County data shows why comps matter so much right now. St. Louis County's August median list price fell to $240,000, down 17.24% from a year earlier, even as sold prices rose. Buyers are paying up for the good houses and ignoring the rest. Build a flip buyers actually want, then price it where the comps say.

Financing Flips in the 7% Rate Environment

Here's the headline everyone saw in late September. Freddie Mac's survey showed the 30-year fixed averaging 7.03% as of September 24, 2026, up from 6.95% the week before. It was the first time rates had topped 7% since January 2025.

Locally, lender quotes ran a bit higher. St. Louis Real Estate News reported the St. Louis 30-year fixed at 7.26% on September 24. That's the rate your resale buyer is looking at, and it directly shapes how much house they can afford.

Graph: Rates sat in a narrow 6.65%–6.71% band through August, then jumped in September, including a 19-basis-point move the week of September 17. Data: weekly readings compiled by House Sold Easy, August 27 reading, and Freddie Mac's September 24 release.

Flippers themselves usually aren't borrowing at 7%, of course. They're borrowing at more. Hard money for fix-and-flip deals was averaging around 10.35% nationally in mid-September, with loans ranging from 9% to 13% plus 1 to 3 origination points. On a $180,000 loan at 10.35%, interest alone runs about $1,550 a month before taxes, insurance, and utilities.

That's why the rate chart above matters even if you're a cash buyer. Your end buyer's payment went up in September, which can soften what they're willing to pay for your finished house. And if your flip stalls, those hard money months add up fast.

Always have a rental backup plan

Before you buy, run a second pro forma that assumes you keep the house as a rental. RentCafe's August 31 figures show St. Louis rents averaging $1,444 across all units, with three-bedrooms around $1,784. DSCR lenders were quoting roughly 7.00% to 7.50% on 30-year loans in September for typical investor profiles, so run your refinance at those numbers and see whether the rent actually covers the debt.

If the flip only works as a flip and would lose money as a rental, you have no safety net. That's a risk you should at least know you're taking.

Missouri's Capital Gains Tax Exemption: Does It Help Flippers?

This is one of the most misunderstood topics we hear about from St. Louis investors, so let's be careful with it.

Missouri passed House Bill 594 in 2025, and as of tax year 2025, individuals can deduct 100% of capital gains reported on their federal return from their Missouri income, which makes the state capital gains tax effectively zero. That's a real benefit for Missouri real estate investors.

But here's the catch for flippers. The exemption covers income that counts as a capital gain on your federal return. Many active flippers are treated by the IRS as dealers, and a flipped house held as inventory generally produces ordinary business income rather than capital gains. Coverage of the new law noted that house flippers benefit when they hold the property for more than 12 months so the profit qualifies for capital gains treatment.

So what does that mean in practice?

• Quick flips (under a year): Plan on the profit being taxed as ordinary income at the federal and state level, plus self-employment tax if you're a dealer.
• Longer holds (over a year): If a flip turns into a rental and you hold it as an investment, a later sale may qualify for capital gains treatment, and the Missouri portion could drop to zero.
• Federal taxes still apply. Missouri's change only affects the state return; federal capital gains rules and depreciation recapture remain in place.

The strategic takeaway: if the market softens and your flip timeline is already stretching, converting to a rental and holding past a year can improve your after-tax outcome in Missouri. Dealer status, holding intent, and how you report the sale all matter, so talk this through with a CPA before you commit to either path. We're not tax advisors, and this is exactly the kind of decision where one conversation can save you thousands.

St. Louis Neighborhoods for Flipping (2026)

St. Louis doesn't move as one market. A flip in Kirkwood and a flip in Dutchtown are basically different businesses. Here's how the main areas are shaping up this fall.

Motivated-seller areas (better buys, more resale risk)

Florissant and Hazelwood (North County). These are some of the most affordable entry points in the metro, and investors can find acquisition prices in the $130,000 to $220,000 range across North and South County workforce corridors. Longer marketing times help you on the buy. Just make sure your resale price fits what local buyers can finance at 7%.

Dutchtown and Gravois Park (South City). Older brick stock, lots of price cuts, and cheaper entry. Dutchtown is typically seen as higher risk with ARVs around $140,000 to $220,000, so keep rehab budgets tight and finishes durable rather than fancy. Both areas also have plenty of two- to four-unit buildings, which gives you a rental fallback.

Stable, predictable ARV areas

Kirkwood, Webster Groves, and similar inner-ring suburbs. Updated homes under $550,000 in these communities often draw multiple offers within the first week. Acquisition is harder, but your resale comps are reliable, and buyers are deep.

St. Charles County. Median sale prices have held in roughly the $340,000 to $365,000 range despite new construction adding inventory around Wentzville and Lake St. Louis. Flips here compete with new builds, so layout and finish level matter a lot.

Value-add city neighborhoods

Tower Grove South, Shaw, Benton Park, and Soulard. Fully updated homes in these historic South Side neighborhoods are selling in about 10 to 18 days. Tower Grove South ARVs commonly land around $200,000 to $300,000, with Shaw a bit higher. These are some of the most dependable flip exits in the city if your finish quality matches the street.

University City and Maplewood. Strong demand and great housing stock, but expect inspection issues with sewers and electrical. If a flip stalls, rental demand is solid.

Here's how the three main St. Louis markets compare heading into fall:

Exit Strategy Planning: Flip vs. Rental Decision Matrix

Every flip should have two exits written down before you close. Here's a simple way to decide which one to use if the market shifts on you:

• If your projected flip profit falls below about 10% of ARV because of longer market times or a softer appraisal, run the rental numbers seriously.
• Use real neighborhood rents, not the metro average. St. Louis rents swing widely by neighborhood, from roughly $1,769 in Lafayette Square to under $1,000 in Dutchtown.
• Compare apples to apples. Weigh the cash from an immediate sale against ongoing cash flow, depreciation, and the possible Missouri tax benefit of a longer hold.
• Check the refinance. A typical $200,000 St. Louis rental renting for $1,750 is roughly break-even at a 7% rate, so a flip-turned-rental often needs a lower loan-to-value refinance to cash flow.

Sometimes the right answer is simply to sell, take a smaller profit, and redeploy the cash into a better deal. Other times, keeping a solid brick three-bed in a strong rental pocket is the better long-term move. What matters is that you decide with numbers, not hope.

Common Flipping Mistakes in the Current Market

We see the same handful of mistakes over and over in St. Louis right now:

1. Overpaying at acquisition. Using a 2021-style max offer without adjusting for 10%+ financing and longer hold times.
2. Over-improving for the block. Putting a $60,000 renovation into a house on a street that tops out at $200,000. Quartz and designer tile won't raise the ceiling on comps.
3. Pricing to aspiration instead of comps. Listing based on what you need to make, not on what similar homes closed at in the last 60–90 days.
4. Ignoring the inspection report you haven't gotten yet. Skipping the sewer scope or electrical check on a pre-1950 house is how a $45,000 budget becomes $65,000.
5. No backup plan. Not underwriting a rental scenario, so a slow resale turns into months of hard money interest with nowhere to go.
6. Buying the cheapest house on the list.  Nationally, sub-$50,000 flips have tended to lose money. Cheap and good are not the same thing.

Key Metrics to Track Before Your Next Flip

Before you write your next offer, check where these numbers sit. They move month to month, so update them every time you underwrite a deal:

• Metro median sold price: $305,000 across the St. Louis MSA in August 2026.
• St. Louis City median sold price: $235,000 in July 2026, down about 5.51% from a year earlier, even as the number of sales rose.
• St. Louis County median sold price: $325,000 in August 2026, up 12.11% year over year, with sales down 10.80%.
• Price per square foot: about $170 in St. Louis, a handy sanity check on your ARV.
• Mortgage rates: 7.03% nationally for the 30-year fixed as of September 24.
• Price-cut share: 17.9% metro-wide. If that climbs toward 20%, buyers (including you) gain more leverage.

The Bottom Line on Flipping in St. Louis Right Now

St. Louis is still one of the more forgiving flip markets in the country. Entry prices are low compared with national numbers, there's a deep supply of solid brick homes, and buyers are still paying well for houses that are done right. What's changed is the margin for error. With 7% mortgages, 10% hard money, rising material costs, and buyers who walk past overpriced listings, the flippers doing well this fall are the ones buying carefully, budgeting honestly, and pricing to sell in the first two weeks.

Do the math line by line, keep a rental backup plan in your pocket, and let the 17.9% of motivated sellers come to you.
