Flipping houses means buying a property below market value, renovating it, and selling it for a profit. It’s a real business, not a weekend hobby, and getting started requires lining up capital, learning to estimate costs accurately, and finding properties where the numbers actually work. Here’s how to approach your first flip with a realistic plan.
Learn the 70% Rule Before Anything Else
The single most important concept in house flipping is knowing what to pay for a property. The industry standard is the 70% rule: you should pay no more than 70% of a home’s after-repair value (ARV), minus the estimated cost of repairs.
The formula looks like this: ARV x 0.70 minus repair costs equals your maximum purchase price. If a house will be worth $300,000 after renovations and you estimate $50,000 in repairs, your maximum offer is $160,000 ($300,000 x 0.70 = $210,000 minus $50,000). That 30% margin covers your holding costs, closing costs on both the buy and the sell, agent commissions, and your profit. If the numbers don’t work at 70%, walk away. New flippers who stretch to 80% or 85% often find their profit evaporates once they account for every expense.
How to Finance Your First Flip
Most first-time flippers don’t pay cash. Several financing options exist, each with different costs and requirements.
Hard money loans are the most common tool for flippers. These are short-term loans (typically 6 to 18 months) secured by the property itself rather than your personal income. Interest rates currently run between 9.5% and 12% for a first-position loan. Lenders will evaluate your credit history, the property’s condition and location, and the loan-to-value ratio you’re requesting. A lower LTV, meaning you’re putting more of your own money in, generally gets you a better rate. Many hard money lenders also charge origination fees of 1 to 3 points (each point is 1% of the loan amount).
Private money comes from individuals rather than institutional lenders. This could be a friend, family member, or someone in a local real estate investing group. Terms are negotiable, and rates may be lower than hard money if the lender trusts your plan. Put any agreement in writing with a promissory note and a lien on the property.
Home equity lines of credit let you borrow against equity in a property you already own, often at lower rates than hard money. The risk is that your primary residence becomes collateral for your flip.
Whichever route you choose, factor financing costs into your 70% rule calculation. A hard money loan at 11% on a $160,000 purchase costs roughly $1,467 per month in interest alone. If the project takes six months, that’s nearly $9,000 in interest before you sell.
Finding Properties Worth Flipping
The best deals rarely appear on the open market. By the time a distressed property hits the MLS, dozens of investors have already seen it and competing offers push the price up. You need to build a pipeline of off-market opportunities.
Direct mail and outreach: Many successful flippers contact homeowners directly by sending letters or postcards to owners in target neighborhoods. Tools like PropStream provide property data, ownership records, and contact information that let you identify owners of distressed or vacant properties and reach out with an offer. This takes volume. Expect response rates of 1% to 3%, meaning you may send hundreds of mailers before landing a deal.
Driving for dollars: This means physically scouting neighborhoods to spot properties that look vacant, neglected, or boarded up. Note the addresses, look up the owners through county records or investor software like DealMachine, and contact them. It’s time-intensive but free.
Foreclosure and tax lien auctions: Foreclosure notices, probate filings, and tax liens are all public records that signal a potential opportunity. Courthouse auctions and sheriff sales often feature properties not listed anywhere else. These deals carry more risk because you may not be able to inspect the property before bidding, and title issues can be complicated.
Agent networks: A real estate agent who works with investors may have access to pocket listings and pre-MLS properties. These are homes being sold privately before they’re marketed publicly. Building a relationship with one or two investor-friendly agents is worth the effort.
Estimating Renovation Costs
Underestimating repairs is the fastest way to lose money on a flip. Before you make an offer, you need a detailed scope of work and a realistic budget. Walk the property with a contractor (or two) and price out every item.
Some rough benchmarks to calibrate your expectations: replacing carpet in a typical three-bedroom home runs $2,000 to $2,500. Tile flooring costs $700 to $1,200 depending on the area covered. HVAC replacement can run $3,000 to $4,000 or more, though sometimes a $200 repair solves the problem. Kitchens and bathrooms are the most expensive rooms to renovate, often $10,000 to $30,000 each depending on the scope. Cosmetic updates like paint, fixtures, and landscaping are cheaper but add up fast across an entire house.
Always add a contingency buffer of 10% to 20% on top of your total estimate. Hidden problems, like water damage behind walls, outdated electrical wiring, or foundation cracks, show up on nearly every project. If your contractor estimates $45,000 in repairs, budget $50,000 to $54,000.
Building Your Team
You don’t need to swing a hammer yourself. What you do need is a reliable group of people who can execute quickly and competently.
- General contractor: Your most important relationship. Get bids from at least three contractors, check their references on completed flips, and verify their license and insurance. A good contractor gives you a detailed written estimate, sticks to timelines, and communicates when problems arise.
- Real estate agent: Ideally someone experienced with investment properties who can help you estimate ARV using comparable sales and move fast when you’re ready to list.
- Home inspector: Pay for a thorough inspection before you buy. The $300 to $500 you spend can save you from a $20,000 surprise.
- Title company or real estate attorney: Handles closings and ensures there are no liens or title defects on the property.
Managing the Timeline
Every month you hold a property costs you money: loan interest, insurance, property taxes, utilities, and lawn care. The goal is to buy, renovate, and sell as quickly as possible without cutting corners on the renovation.
A typical first flip takes 4 to 6 months from purchase to sale. Plan for 1 to 3 months of renovation depending on the scope, then 1 to 3 months on the market. In slower markets or with larger projects, the timeline stretches. Before you buy, map out a realistic schedule week by week: permits in week one, demolition in week two, and so on. Delays happen, but having a plan keeps your contractor accountable and your holding costs predictable.
Order materials and schedule subcontractors before closing day so work can begin immediately. Every week of idle time is money lost.
How Flipping Income Gets Taxed
This catches many new flippers off guard. If you flip houses regularly, the IRS classifies you as a dealer rather than an investor. That means your profit is treated as ordinary income, not capital gains, and it’s also subject to self-employment tax (currently 15.3% on top of your income tax rate).
Capital gains treatment, which offers lower tax rates for assets held longer than a year, generally doesn’t apply to flippers because the properties are held for months, not years, and are treated as inventory rather than capital assets. On a flip that nets $50,000 in profit, you could owe $15,000 to $20,000 or more in combined federal income and self-employment taxes depending on your overall income.
Track every expense meticulously. Purchase costs, renovation materials, contractor invoices, loan interest, insurance premiums, property taxes, and selling costs all reduce your taxable profit. Keep receipts for everything and use a dedicated bank account for each project so your records are clean.
Running the Numbers on a Sample Deal
Here’s what a first flip might look like on paper. Say you find a property with an ARV of $250,000. Using the 70% rule: $250,000 x 0.70 = $175,000. You estimate $40,000 in repairs, so your maximum purchase price is $135,000.
You finance $135,000 with a hard money loan at 11% interest and put $40,000 of your own cash toward renovations. Renovation takes 10 weeks, and the house sells after 6 more weeks on the market. Total hold time: about 4 months. Your costs break down roughly as follows: $135,000 purchase, $40,000 renovation, $5,000 in loan interest and fees, $3,000 in holding costs (taxes, insurance, utilities), and $15,000 in selling costs (agent commissions and closing costs). Total investment: $198,000. Sale price: $250,000. Pre-tax profit: $52,000.
That looks great on paper, but notice how sensitive the math is. If repairs run $10,000 over budget or the house sits on the market an extra two months, your profit drops to $35,000 or less. If both happen and the sale price comes in $10,000 under ARV, you’re looking at $20,000. The margin for error on a flip is thinner than most people expect, which is exactly why disciplined buying using the 70% rule matters so much.
