You’ve seen the shows. A charismatic couple buys a literal dump, swings a sledgehammer for forty-two minutes, and walks away with a check for a hundred grand. It looks easy. It looks like a shortcut to early retirement. But if you ask a pro how do you flip houses in the real world—outside the HGTV editing bay—they’ll probably tell you it’s more about spreadsheets and sweat than shiplap and subway tile.
Flipping houses is basically high-stakes gambling where you can actually influence the cards. It’s a business of margins. You buy a distressed asset, force appreciation through strategic renovation, and sell it to someone who wants a "turn-key" home. Simple, right? Not really. In 2024 and 2025, the market shifted. High interest rates and low inventory changed the math. You can't just slap on some "Agreeable Gray" paint and expect a bidding war anymore. You have to be precise.
The Brutal Math of the 70% Rule
Most rookies fail because they overpay. They get emotional. They see a "cute" craftsman and ignore the fact that the foundation is sinking into a swamp. Experienced flippers live by the 70% Rule.
Basically, you shouldn't pay more than 70% of the After Repair Value (ARV) minus the costs of the actual renovation. If a house will be worth $400,000 once it’s beautiful, and it needs $60,000 in work, your max purchase price is $220,000.
$400,000 \times 0.70 = $280,000$
$280,000 - $60,000 = $220,000$
That 30% gap isn't just profit. It’s your safety net. It covers closing costs, the "holding costs" like taxes and utilities, the 6% realtor commission when you sell, and the inevitable "oh crap" moments—like finding out the wiring was done by a drunk squirrel in 1974. If you pay $250,000 for that same house, your profit disappears before you even pick up a hammer.
Where the Real Deals Are Hiding
You won’t find a good flip on the MLS. Well, rarely. By the time a house hits Zillow, every amateur in the zip code is bidding on it. To make money, you have to find "off-market" deals. This is where the grind happens.
Serious flippers use "driving for dollars." You literally drive around neighborhoods looking for long grass, boarded windows, or piles of mail. You look for the "ugly" house on a "pretty" street. Then you track down the owner. Direct mail campaigns still work. So does "skip tracing" to find phone numbers of out-of-state owners who inherited a property they don't want.

Wholesalers are another source. These are middle-men who find distressed properties, put them under contract, and "assign" that contract to you for a fee, usually $5,000 to $10,000. It’s less work for you, but it eats into your margin.
Hard Money vs. Your Own Cash
How do you pay for it? Most people don't have $300,000 sitting in a checking account. Traditional banks hate house flips. They want 30-year stability, not a six-month chaotic renovation.
This is where Hard Money Lenders come in. These are private companies that lend based on the asset, not just your credit score. They’re expensive. You might pay 10% to 12% interest and "points" (upfront fees). But they close fast. In a competitive market, being able to close in 10 days is a superpower. Just remember: the clock is ticking. Every month you hold that house, you’re bleeding interest. If a flip takes nine months instead of four, the hard money lender might be the only one making money.
The Renovation Trap: Don't Over-Improve
One of the biggest mistakes is "luxury creep." You decide the kitchen needs quartz. Then you think, well, if I’m doing quartz, I should probably do high-end custom cabinets. Stop.
You aren't building your dream home. You’re building a product for a specific demographic. If the neighborhood supports a $300,000 price point, putting in a $50,000 kitchen is financial suicide. Focus on the "Big Three": Kitchens, Baths, and Curb Appeal.
The Order of Operations
- The Invisible Stuff: Roof, HVAC, plumbing, electrical. If these aren't right, the inspector will kill your sale later.
- The Layout: Can you knock down a non-load-bearing wall to create an open floor plan? People love "open concept" even if it's becoming a bit of a cliché.
- The Cosmetics: Flooring, paint, lighting fixtures. These offer the highest Return on Investment (ROI).
Don't ignore the smell. If a house smells like cats or cigarettes, no amount of crown molding will save you. You have to kill the odor at the subfloor level. Honestly, sometimes you just have to rip it all out.
The "Fix and Flip" Tax Reality
The government wants their cut. If you buy and sell a house in under a year, your profit is taxed as Short-Term Capital Gains. That’s basically the same as your regular income tax bracket. It can be as high as 37%.
Compare that to Long-Term Capital Gains (if you hold for over a year), which tops out around 20%. This is why some people pivot to "Wholetailing"—doing very minor repairs and selling quickly—or "BRRRR" (Buy, Rehab, Rent, Refinance, Repeat) to build long-term wealth instead of quick cash.
Dealing with Contractors
This is the hardest part of the business. Period.
Good contractors are busy. Bad contractors are available. You’ll hear stories of guys taking a deposit and vanishing to Tahiti. To avoid this, never pay more than 10-15% upfront. Use a "draw schedule." They get paid when specific milestones are met. Rough-in plumbing done? Here’s a check. Drywall hung? Here’s another.

Always get three quotes. Not because you'll take the cheapest—the cheapest guy is often the most expensive in the long run because you have to hire someone else to fix his mistakes—but because it helps you understand the true scope of the work.
What Most People Get Wrong About the Exit
You finished the house. It’s gorgeous. You put it on the market. Now what?
The market doesn't care what you spent. It only cares about "Comps" (comparable sales). If three houses similar to yours sold for $350,000 in the last six months, your house is worth $350,000. It doesn't matter if you spent $100,000 on Italian marble.
Pricing it right from day one is critical. If a house sits for more than 30 days, it develops a "stink." Buyers wonder what’s wrong with it. They’ll start lowballing you. Sometimes, pricing it $5,000 under market value is smarter because it triggers a bidding war that drives the price $20,000 over market.
Actionable Steps to Get Started
If you’re serious about figuring out how do you flip houses, don't go buy a house tomorrow. Do this instead:
- Study your local market daily. Look at "Solds" on Zillow. Not just what's for sale, but what actually closed and for how much.
- Build a "Core Four" team. You need a contractor, a rockstar real estate agent, a hard money lender, and a wholesaler.
- Analyze 50 deals on paper. Run the 70% rule on 50 different houses. Don't buy any of them. Just learn the numbers until you can spot a deal in thirty seconds.
- Check your credit. Even with hard money, a better credit score gets you lower interest rates, which means more profit in your pocket.
- Start small. Your first flip shouldn't be a total gut job or a historic restoration. Find a "carpet and paint" house where you can learn the ropes without risking bankruptcy.
Flipping is a job. It’s a stressful, dusty, expensive job. But if you can master the math and manage the people, it’s one of the fastest ways to build significant capital in the American economy. Just keep your emotions out of the crawlspace.
