Getting Started with House Flipping: A Beginner's Guide

House flipping is buying a house for less than it will be worth after rehab work, fixing it, and selling it. That's the whole job. You buy, you renovate, you sell. Profit is what's left after every cost, not the gap between your purchase price and the list price.

In the current 2026 market—tighter inventory, elevated material and labor costs, higher holding expenses, and national gross ROI recently reported near 23%^[1], the margin for error is smaller than it was a few years ago.

Most first flips fail for a simple reason. The buyer paid too much, or they estimated costs that were too low. The money is made on the buy. If the purchase is wrong, no paint color or staging photo will save the deal. You can't renovate your way out of a bad price. The sale comps cap what the house can bring. Extra granite doesn't raise a $200,000 street to $230,000.

This post covers the high-level process. Later posts can go deeper on finding deals, financing, and running the job. Start here so you know what buying right actually means.

What a flip is

You buy a house that's worth less than it should be, usually because it needs work or it sold under stress. You renovate it so it can sell at the After Repair Value, or ARV. ARV is what similar fixed-up homes on that block are selling for right now, not what you hope they will sell for next spring.

House flipping means purchasing a property, renovating it to raise its value, and selling it for a profit.

Since this is important , we will repeat it. Three parts matter: buy right, renovate with a tight scope, and sell without sitting too long. The first one carries the most weight. Overpaying or underestimating costs is the most common way first-time flippers lose money.

Success still rests on three fundamentals: buying right, renovating with discipline, and selling strategically.

The 70% rule is a fence, not an underwrite

A common starting rule is the 70% rule. One of the most useful guidelines for beginners. It says you should pay no more than 70% of ARV, minus the repair budget.

Formula: Maximum purchase price = (ARV × 0.70) - repair costs

Example. ARV is $200,000. Repairs are $30,000. Seventy percent of $200,000 is $140,000. Subtract $30,000. The most you should pay is $110,000.

That number is a fence. It keeps you from writing a silly offer. It isn't a complete underwrite.

Experienced operators sometimes adjust to 65% in slower markets or 75%+ in highly competitive areas where deals require paying closer to ARV.^[1]

The rule does not automatically include holding costs, selling costs, or taxes—those must be layered on separately and considered when underwriting the deal. If you treat $110,000 as "the deal works" and stop there, the win on paper is fiction.

Walk the same example all the way through.

You buy at $110,000 and spend $30,000 on work. You have $140,000 in the house before the carry/holding cost. You sell at the $200,000 ARV. The gross spread looks like $60,000. That's the number people screenshot.

Now layer the missing stack.

Holding costs are the bills that run while you own it.

• Interest on the loan.

• Property taxes.

• Insurance.

• Utilities.

• HOA dues if there are any.

• etc

A four to six month flip can easily burn $8,000 to $15,000 here, more if the loan is expensive or the job slips. Say five months at $2,200 a month. That's $11,000.

Selling costs are what it takes to get to the closing table on the way out.

• Agent commission

• Seller closing costs

• Transfer taxes in some states

• Any small credits you give to keep the buyer

• etc

Six to eight percent of the sale price is a common planning range. On a $200,000 sale, that's $12,000 to $16,000. Use 7% and you're at $14,000.

Tax is last, and it is real. After-tax take-home is the number that decides the offer, not gross profit.

Put those on one page:

• Sale at ARV: $200,000

• Purchase: $110,000

• Repairs: $30,000

• Hold: $11,000

• Sell: $14,000

• Left before tax: $35,000

The $60,000 spread was never your money. $35,000 before tax is a different deal, and tax takes another bite.

We will cover taxes and various strategies that impact what taxes you pay in another upcoming post.

If the job runs long, or the sale comes in under ARV, the leftover shrinks fast. A $10,000 miss on price plus two extra months of hold can cut that $35,000 in half.

That's why 70% is a starting fence. You still have to build a full cost stack, then decide if the leftover is worth the risk and the time.

gross, before rehab, hold, and sell. Net is lower. Plan with net.

Experienced buyers sometimes tighten the fence to 65% when the market is slow, or stretch toward 75% when they're competing and they've already modeled hold, sell, and tax. The adjustment isn't a vibe. It's a math change after the rest of the stack is on the page.

You'll see headlines that say flippers made about 23% last year. Those figures are usually gross, before rehab, hold, and sell. Net is lower. Plan with net.

1. Get the financing straight first

Financing cost comes out of net profit. So does a loan that forces you to sell before the house is ready.^{[2] [3]}

A regular mortgage is usually too slow and too picky for a flip. Hard money and private fix-and-flip loans close faster^[4]. They look at the property and the ARV more than they look at you as a W-2 borrower. They can fund the purchase and the rehab. They also cost more, which is why hold has to sit in the underwrite and not in a footnote.

Before you tour houses, know three things.

• What the money costs.

• How long you can hold.

• What happens if the job runs 60 days long.

If you can't say those out loud, you're not ready to write an offer.

2. Build a small team

You don't need a company but Even strong DIY operators rarely succeed in isolation.

The power of one is still one.

Focus first on three roles:

• A reliable general contractor (or proven subs) who delivers quality work on time and on budget—crucial for controlling rehab costs and timelines.

• An investor-friendly real estate agent experienced with flips, distressed properties, or off-market deals.

• A lender who understands short-term investment properties.

Meet them before you need them.

Start networking early through local real-estate investment meetups, referrals, and platforms such as BiggerPockets. Prioritize track record and reliability over the lowest bid.

The strength of one is limited, but a solid network multiplies your opportunities, reduces risks, and accelerates your path to consistent profits. Your future flips (and ROI) will thank you.

One final point on this subject : A cheap bid that slips eight weeks isn't cheap. That delay shows up as holding cost, which the 70% fence never saw.

3. Find and Underwrite the Right Property

Look in neighborhoods where fixed-up homes already sell, showing increased demand. Look at days on market to get a feel for the market in the area. A dated house on a street that moves will beat a pretty house on a street that doesn't.

We will cover how you find the the RIGHT property in a future post.

Off-market, driving for dollars, wholesalers, and a tight MLS search all work. The skill that matters on day one is underwriting before you offer.

You need current comps, not last year's. To make an educated decision your tool of choice should provide you the comps , how well they match the property ( more or less bedrooms, batch, lot size) , Days on Market (DOM) for the sale , Square foot cost compared to your target ARV cost per square foot.

The critical skill is rigorous underwriting before you make an offer: accurate comps, conservative ARV, detailed scope of work, and a complete cost stack that includes acquisition, closing, holding, selling, and contingency + tax.

If any of those are a guess you haven't checked, the offer is a guess.

Conservative ARV means you use recent solds that a buyer would actually choose instead of this house, in similar condition after your planned work. You don't average in a peak sale from two years ago. You don't pick the one remodel that has a pool and a second lot. If three honest comps say $195,000 to $205,000, your ARV is not $220,000.

4. Build a budget you can defend

Walk the house. Hire an inspector if you're not sure what you're looking at. Split the work into cosmetic and systems (foundation, HVAC, electrical, plumbing). Paint and flooring aren't the same class of risk as foundation, roof, HVAC, electrical, or plumbing.

Write a line-item budget. Add a 15 to 20 percent contingency. First-time flippers lose money by skipping that pad, then meeting a $15,000 plumbing surprise with no room left.

Model holding costs against a real calendar. Interest, taxes, insurance, and utilities don't pause because the tile guy is late. Contingency covers surprise work. Hold covers surprise time. They are not the same line.

5. Run the renovation like a job, execution discipline is key

Treat the renovation like a project business. The most common profit killers are scope creep and schedule slips. Practical controls include:

• Locking scope and pricing early.

• Building realistic buffers into both budget and timeline.

• Prioritizing the critical path.

• Using frequent check-ins and milestone payments.

• Tracking actual costs against the budget in real time.

Experienced operators commonly target 90–120 day total project cycles, from purchase to sale, while staying at or under budget. Review every completed flip to improve the next one.

Critical path is the items that block everything else.

If a change order doesn't raise what a buyer will pay, it isn't an upgrade. It's a donation.

6. Price it to sell for speed

1. Work with an investor-experienced agent. Run fresh, accurate comps. Price to move rather than to maximize every last dollar if the market is selective or rates are elevated. Chasing the last few thousands on list price is how a flip sits and the longer days on market increase holding costs and erode net profit. If the market is picky or rates are high, a slightly lower list that sells in two weeks can beat a proud price that sits for two months

Speed is part of the underwrite you did on day one. Don't abandon it at the yard sign.

By combining proactive planning, tech-enabled visibility through tools, strict accountability, and conservative buffers, top flippers minimize overruns. If you're scaling, consider a dedicated project manager for larger volumes!

Common mistakes

• Underestimating renovation costs and timelines — A $15k plumbing or HVAC surprise on a tight budget can erase the entire projected profit.

• Overpaying for the property — Violating the 70% rule (or failing to adjust it properly for your market) is the single largest source of first-deal losses.

• Skipping a real inspection — Hidden structural, electrical, or plumbing issues surface after closing.

• Over-improving for the neighborhood — High-end finishes that the local comps will not support rarely pay for themselves.

• Ignoring holding and sale costs — Interest, taxes, insurance, and utilities continue every month the property sits. Commission and closing cost are not optional.

• Using stale or optimistic comps — Overestimating ARV in a stabilizing market is a frequent and expensive error.

• Stopping at gross profit. If you haven't subtracted hold, sell, and tax, you don't know what the offer is worth.

That's the job

Buy below a fence you can defend. Layer hold, sell, and tax before you call it a win. Finance the hold you might actually need. Keep the team small and the scope tight. Sell without lingering.

The rest is practice. Do the first one with conservative numbers, then tighten from results, not from hope.
