Learn How to Flip Houses

The complete, free step-by-step guide from the team that has powered scaling house flipping businesses since 2018. 50+ articles, videos, and real case studies covering every phase of a flip.

Overview

This is the complete, free guide to flipping houses, built from nearly a decade working alongside active real estate investors. You'll learn how a flip actually works: the one-time foundation you set up before your first deal, and the repeatable cycle you run on every property after. Work through it start to finish, or jump to the phase you're on. Every chapter links to in-depth guides, videos, and real case studies.

Key Takeaways

  • House flipping means buying below value, renovating, and reselling. The profit is decided when you buy, not when you sell.
  • It's two parts: a one-time foundation (decide, set up your business, line up financing) and a repeatable per-flip process (find, analyze, estimate, inspect, prepare, manage, sell).
  • Two numbers make or break every deal: your After Repair Value and your rehab estimate. Nail both before you make an offer.
  • Use the 70% Rule to set your maximum offer: (ARV × 70%) − rehab costs. That 30 percent cushion covers your buying, holding, financing, and selling costs.
  • Most flippers fund deals with hard money, not cash, so line up financing before you start hunting.
  • Protect your margin with a 10 to 20 percent rehab contingency and cash reserves. The deals that go bad are usually the ones with no cushion.

How does house flipping work?

House flipping is the process of buying a property below market value, renovating it to raise its value, and reselling it for a profit. Your profit is the spread between your all-in cost and the resale price (the After Repair Value), minus every cost in between: purchase, rehab, financing, holding, and selling. That's why flipping rewards buying right and estimating accurately far more than it rewards the renovation itself.

But before you analyze a single deal, understand this: flipping is a business, not a hobby. The people who lose money treat it like a side project they'll figure out as they go. The ones who last in this business, set up a proper foundation first, so when a deal comes across their desk they can move fast, fund it, and execute without scrambling. Getting this groundwork right is what lets you hit the ground running and sidestep the pitfalls that sink first-time flippers.

First, build your house flipping business foundation. This is one-time setup you do before your first deal:
Then, run the flip. Once your foundation is in place, flipping becomes a repeatable six-step process you run on every property:
Build the foundation once. Then run the cycle again and again, faster and sharper each time.

Phase 1 - Build your house flipping business foundation

Before you chase your first deal, you need to set up your business the right way. These three steps are your one-time foundation, the groundwork that lets you move fast and avoid the pitfalls that sink first-time flippers.
Step 1 · Decide if flipping is for you
Before you spend a dollar, get honest about whether this business fits your life, your finances, and your tolerance for risk. The TV shows compress six stressful months into twenty-two tidy minutes. Real flipping is contractors who no-show, budgets that creep, and market swings you can't control.

What flipping actually demands: access to capital (your own or a lender's) plus reserves; the time to manage the work and decide fast; and the stomach to carry real financial risk on every deal. Why people do it anyway: profit on one deal that can rival a year of saving, forced appreciation you create instead of wait for, and a repeatable skill that compounds.

Bottom line: Most people who say they'll flip a house never buy their first one. The ones who succeed treat it like a business from day one, not a weekend gamble.
Step 2 · Set up your house flipping business
Flipping is a business, and the investors who scale set it up like one before their first project. Get the structure right: form an LLC to separate personal assets from the business, open a dedicated business account and get your EIN, and start bookkeeping from day one. Write a simple plan (market, property type, funding, profit goals; not fifty pages). And know how flips are taxed: usually ordinary income, not long-term capital gains, often with self-employment tax. That surprises new flippers every year.

Bottom line: An LLC, clean books, and a clear plan are what let you operate like a professional. Set it up once and it carries every future deal.
Step 3 · Line up your financing
Very few flippers pay cash. Most fund deals with a hard money loan: asset-based, short-term, secured by the property rather than your credit. Lenders fund a large share of purchase plus most or all of the rehab based on ARV, and you pay for speed (often 1 to 3 points and 8 to 12 percent or more), bringing the down payment, closing costs, and reserves. Vet the lender: legit ones are transparent about points, rates, and draws; predatory ones bury fees and demand big sums up front. Know your other options too (private money, lines of credit, partners, seller financing, DSCR for the refinance).

Bottom line: The deal won't wait while you find money. Get pre-qualified now so when you find a deal in Step 4 you can offer the same day.

Phase 2 - Run Your First Flip

With your foundation in place, this is where the real work happens. These six steps are the flip itself, the process you run on every property, from finding a deal to selling it for a profit.
Step 4 · Finding deals
The hardest part, and it gets harder in a hot market. Winners build a pipeline instead of chasing every listing. Narrow to a farm area you can drive and a property type you understand. Work multiple lead sources: the MLS and investor-friendly agents, wholesalers, direct mail and driving for dollars, plus auctions, probate, and your network. Target motivated sellers, because price flexibility lives with distress, inheritance, and tired landlords, not on a polished retail listing.

‍Bottom line: Don't force a deal because you're impatient. A full pipeline is what lets you walk from bad numbers, which is exactly what Step 5 asks you to do.Finding Deals will be one of the biggest challenges in your house flipping business.  
Step 5 · Analyzing deals so you don't overpay
Where deals are won or lost, before you own the house. Start with the After Repair Value from three to five sold comps nearby, similar in size, age, and finish. Then apply the 70% Rule:


Maximum Allowable Offer
= (ARV × 70%) − Estimated Rehab Costs
ARV $300,000, rehab $50,000 → ($300,000 × 0.70) − $50,000 = a $160,000 maximum offer.
That 30 percent haircut covers the costs the rule hides: buying costs, holding costs, selling costs, and financing costs. Then set your minimum profit and walk if the deal doesn't clear it (many flippers won't touch a project under $25,000 to $50,000 projected).

Bottom line: Get this right and the rest is execution. Get it wrong and no hustle on the rehab saves a deal you overpaid for.

Step 6 · Estimate the rehab costs, so you have an accurate budget
The number most likely to sink a deal, so build it before you buy. Start with a Scope of Work listing every task room by room so everyone bids the same job. Know the three estimating methods: cost per square foot for a gut check, line-item unit costs for accuracy, and contractor bids to validate against the market. Don't forget the adders (dumpsters, permits, temp utilities, cleanup) and a 10 to 20 percent contingency, because you will find something behind a wall.

Bottom line: This estimate feeds straight into your Step 5 offer, so accuracy here protects the whole deal. It's your best defense against the leaks that eat your profit.

Step 7 · Inspect the property
Under contract, use your due diligence period to confirm what you're buying. Cosmetic problems are cheap and predictable. The big systems and structural issues are what turn a clean flip into a money pit: foundation, roof, electrical, plumbing and sewer, HVAC, mold. Bring in a professional inspector even if you're experienced, then take what you find back to your Step 6 estimate and re-price, renegotiate, or walk.

Bottom line: Know the difference between a cosmetic fix and a structural deal-killer. The first is a line item. The second is a reason to walk.
Chapter 8: Preparing for Your Rehab
The work before you take possession decides whether the rehab runs smooth or spirals. Turn your Scope of Work into apples-to-apples bids from multiple contractors. Vet them on license, insurance, references, and recent work, remembering the cheapest bid is rarely the cheapest job. Protect yourself on paper: tie payments to completed milestones, never overpay up front, and confirm permits, insurance, and written contracts.

Bottom line: Walk into day one with contractors lined out, scope locked, and paperwork done. Every hour of prep now saves a day of chaos later.

Chapter 9: Managing the Rehab
Where your plan meets the jobsite. Run the project phase by phase (demo, rough-in, finishes) on a schedule, with daily logs and photos. Track every draw against your estimate and catch overruns while you still can. Then close out: finish the punch list, pass final inspections, list and price to your ARV, settle the books for your final P&L, and handle 1099s at year end.

Bottom line: When the sale closes you've completed the cycle. The foundation is already built, so your next flip is just Steps 4 through 9 again, faster and sharper each time.
Chapter 10: Managing Your Budget & Expenses
This is where you find out what you actually made. We'll cover tracking expenses against your budget, closing out the books, handling taxes and 1099s, and reading your final profit and loss so the number is real, not a guess.
Frequently Asked Questions about Flipping Houses
How much does it cost to flip a house?
The total cost to flip a house is far more than the purchase price and the rehab budget. You also carry buying costs, holding costs, financing costs, and selling costs. Rehab budgets commonly run from around $20,000 for a light cosmetic refresh to $100,000 or more for a full gut, plus roughly 10 to 15 percent of your ARV in fixed costs. The way to avoid surprises is to itemize every one of those buckets before you make an offer, not after.

How much can you make flipping houses?
Profit on a flip is what's left after every cost is paid: purchase, rehab, buying, holding, financing, and selling. Many active flippers target a minimum net profit of $25,000 to $50,000 per deal, though margins swing with your market, your purchase price, and how tightly you control the rehab budget. The number you keep is really decided before you buy, when you run the deal, not at the closing table when you sell.

Is flipping houses profitable?
Flipping houses can be profitable, but the profit is not automatic. It comes from buying at the right price, estimating the rehab accurately, and controlling costs through the project. The flippers who lose money almost always lose it on the buy or on a rehab budget that quietly leaked. Get your underwriting right up front and profitability tends to follow.

How much money do you need to start flipping houses?
You rarely need the full purchase price in cash. Most flippers fund deals with hard money or private lenders who cover a large share of the purchase and rehab, so your out-of-pocket is typically the down payment, closing costs, and a reserve. Plan to have cash for the gap plus a cushion for holding costs and overruns, because the projects that go sideways are usually the ones with no reserve.

What is the 70% rule in house flipping?
The 70% Rule is a quick guideline for the most you should pay for a flip. It says your maximum offer should be no more than 70 percent of the After Repair Value, minus your estimated rehab costs. On a house with a $300,000 ARV and a $50,000 rehab, that's ($300,000 × 0.70) − $50,000, or a $160,000 maximum offer. The 30 percent gap is your cushion for buying, holding, financing, and selling costs, plus your profit.

What are holding costs in house flipping?
Holding costs are the ongoing expenses you pay to own a property while you rehab and sell it. They include loan interest, property taxes, insurance, and utilities, and they often run 1 to 2 percent of your purchase price per month. Every extra week on the market eats into your profit, which is why finishing on schedule matters as much as finishing on budget.

How long does it take to flip a house?
Most flips take somewhere between four and eight months from purchase to sale, though it depends on the size of the rehab and your local market. A light cosmetic refresh can turn in a couple of months, while a full gut or an addition can run well past six. Because every month you own the property adds holding costs, a realistic timeline is part of your deal analysis, not an afterthought.

Can you flip a house with no money?
It's possible to flip with little of your own cash, but not truly none. Investors use hard money or private lenders to cover most of the purchase and rehab, partner with someone who brings the capital, or use creative financing like seller financing. You'll still need money for the down payment, closing costs, and reserves, or a partner who provides it. Going in with zero cushion is how good deals turn into bad ones.
