How to Calculate Real Flip Profit in 2026 (Not Just the Spread)

How to Calculate Real Flip Profit in 2026 (Not Just the Spread)

Most new flippers look at the spread: “I buy for $200,000, sell for $300,000, profit is $100,000.” That’s a fantasy. In 2026, with conventional rates at 7.5% and hard money at 12%, the spread is just the starting point. Real profit gets eaten by holding costs, loan fees, and rehab overruns. Here’s how to calculate what you’ll actually walk away with.

Step 1: Know Your ARV, Not Your Guess

Your After Repair Value (ARV) is the sale price after renovations. Overestimate it by 5% and your profit evaporates. Use comps from the last 90 days—same neighborhood, similar size, same bed/bath count. Don’t rely on Zestimates.

Plug your numbers into the ARV Calculator to get a range. For 2026, expect ARVs to be flat or slightly down in most metros (2–3% annual appreciation max). Assume a conservative ARV of $285,000 on a $200,000 purchase if comps support it.

Step 2: The 70% Rule (Adjusted for 2026 Rates)

The old 70% rule says: Maximum purchase price = ARV × 70% – repair costs. In 2026, with 12% hard money, that rule is too aggressive. You need to drop it to 65% or even 60% if the flip will take over 12 months.

Example: ARV $285,000, repairs $40,000.

• 70% rule: 285,000 × 0.70 = $199,500 – 40,000 = $159,500 max purchase.
• 65% rule: 285,000 × 0.65 = $185,250 – 40,000 = $145,250 max purchase.

Why the discount? Hard money at 12% on a $200,000 loan costs $2,000 per month in interest alone. On a 6-month flip, that’s $12,000. Conventional money at 7.5% is cheaper but harder to qualify for flips. Use the 70% Rule Calculator to test both scenarios with your local rates.

Step 3: Rehab Costs Are Always Higher Than Your Budget

Contractors in 2026 are charging $150–$250 per square foot for full rehabs. Kitchens run $25,000–$40,000, bathrooms $10,000–$20,000. Add a 15% contingency for surprise issues—foundation cracks, old wiring, mold behind drywall.

Run your specific scope through the Rehab Cost Estimator. For a 1,500 sq. ft. house with new kitchen, two baths, flooring, and paint, expect $55,000–$70,000 in total costs. Don’t skimp on inspection—a $500 inspection can save you $10,000.

Step 4: Hard Money Loan Costs (The Silent Profit Killer)

Hard money lenders in 2026 charge 12% interest plus 2–4 points upfront. On a $200,000 loan:

• Points: $4,000–$8,000.
• Monthly interest: $2,000.
• Total cost over 6 months: $16,000–$20,000.

Use the Hard Money Calculator to factor in your specific terms. If you’re using conventional financing at 7.5%, the monthly cost drops to $1,250, but you’ll need a 25% down payment and a 12-month seasoning period.

Step 5: Holding Costs—The Daily Burn

Every day you hold the property, you bleed money. In 2026, expect:

• Property taxes: $200–$400/month.
• Insurance (vacant property): $150–$300/month.
• Utilities: $100–$200/month.
• HOA fees (if applicable): $100–$500/month.

On a 6-month flip, holding costs add up to $3,000–$8,000. If the flip goes to 9 months (common with contractor delays), double that.

Step 6: Selling Costs—Don’t Forget the Realtor

Real estate agent commissions are 5–6% in most markets. On a $285,000 sale, that’s $14,250–$17,100. If you sell FSBO, you save that, but you’ll lose on exposure. In 2026, buyer’s agents are still getting 2.5–3%.

Plus: closing costs (title, escrow, transfer taxes) are 1–2%, or $2,850–$5,700. And if you’re flipping in a city like Austin or Denver, transfer taxes alone can be 1.5%.

Step 7: The Real Profit Calculation (2026 Example)

Let’s put it together for a typical flip:

• Purchase price: $160,000 (using the 65% rule).
• Hard money loan: $160,000 at 12%, 3 points.
• Rehab costs: $55,000.
• Holding period: 6 months.
• ARV: $285,000.

Costs:

• Loan points: $160,000 × 3% = $4,800.
• Interest: $160,000 × 12% ÷ 12 × 6 = $9,600.
• Rehab: $55,000.
• Holding costs (taxes, insurance, utilities): $4,000.
• Selling costs (6% commission + 2% closing): $285,000 × 8% = $22,800.
• Total costs: $160,000 + $4,800 + $9,600 + $55,000 + $4,000 + $22,800 = $256,200.

Profit: $285,000 – $256,200 = $28,800.

That’s 11% return on total capital (your down payment + costs). Not bad, but one month of delay drops it to $26,800. Two months delay, you’re at $24,800.

Step 8: Use the Fix and Flip Calculator

Manually running these numbers is painful. The Fix and Flip Calculator does it in 30 seconds. Input your purchase price, rehab estimate, ARV, loan terms, and holding period. It sp
