The Fix-and-Flip Market in 2026
With median US home prices at $412K and renovation costs averaging $65K, the fix-and-flip market remains active with roughly 300,000 flips completed annually. The average flipper margin hovers around 10% of ARV. The 70% Rule remains the gold standard for evaluating deals before making offers.
Key Takeaways
- •70% Rule: Max purchase = (ARV × 0.70) − rehab. Deals above this rarely pencil.
- •Contingency: Budget 15-20% on rehab for overruns and surprises.
- •Holding costs: Taxes, insurance, utilities, and HOA add up—plan for 4-6 months.
- •Financing: Hard money (10-15%) is fast; conventional (6-8%) is cheaper but slower.
Did You Know?
The 70% Rule leaves ~30% for profit, holding, financing, and closing.
Hard money lenders typically fund in 5-10 days vs 30-45 for conventional.
Average flip timeline is 4-6 months from purchase to sale.
Rehab overruns of 15-25% are common—always add contingency.
Selling costs (agent commission) often run 6-8% of ARV.
Cash deals avoid interest but tie up capital; ROI can still be strong.
How Does the 70% Rule Work?
1. Maximum Purchase Price
Max Purchase = (ARV × 0.70) − Rehab. This reserves 30% for profit, holding, financing, and closing.
2. Why 70%?
The remaining 30% covers your profit margin (target 10-15%), holding costs, financing, and both sides of closing. Paying more than 70% leaves little buffer for surprises.
3. When to Adjust
In hot markets, some flippers use 65% for more cushion. In distressed areas, 75% may work if you can execute quickly and control costs.
Expert Tips
Get 3 Bids
Always get at least 3 contractor bids for rehab. Scope creep is the #1 profit killer.
Short Hold
Every extra month adds holding costs. Plan for 4 months; budget for 6.
ARV Conservatively
Use comparable sales, not list prices. Subtract 5% for market risk.
Know Your Exit
Have a backup plan: rent, wholesale, or partner if the flip doesn't sell.

FAQ
What is the 70% Rule in house flipping?
The 70% Rule states your maximum purchase price should be (ARV × 0.70) minus rehab costs. This leaves ~30% margin for profit, holding costs, financing, and closing. Example: $250K ARV, $40K rehab → max purchase $135K.
How much does a typical house flip cost?
Total project costs typically run 85-95% of ARV. A $250K ARV flip might cost $212K-$237K including purchase, rehab, holding (4-6 months), financing, and closing. Average flipper margin is ~10% of ARV.
What is hard money lending and how does it work?
Hard money loans are short-term, asset-based loans from private lenders. Rates typically 10-15%, terms 6-18 months, LTV 65-75%. No income verification—approval based on property value and exit strategy. Points (2-4%) are common.
How long does an average flip take?
Most flips complete in 4-6 months: 2-4 weeks to close, 2-4 months for rehab, 2-4 weeks to list and sell. Delays from permits, labor, or market conditions can extend to 8-12 months.
What are the biggest risks in house flipping?
Rehab overruns (often 15-25%), longer holding periods, ARV shortfalls if market softens, financing costs on extended holds, and unexpected structural issues. Always budget 15-20% contingency.
How do I estimate rehab costs accurately?
Get 3 contractor bids, use $/sqft benchmarks (cosmetic $15-30, moderate $30-60, full gut $60-150), add 15-20% contingency, and factor permits and design. BiggerPockets and local REIA groups share cost data.
