What is the 70% rule in house flipping?

The 70% rule says you should pay no more than 70% of the after-repair value minus repair costs. For a $300,000 ARV with $50,000 in rehab, your max offer is $160,000. The 30% buffer covers costs, financing, and profit.

How accurate is the AI ARV estimate?

ARV is built from recent comparable sales matched on location, size, and condition tier — not an automated Zestimate. The system also tracks its predictions against actual sale prices over time to keep estimates calibrated.

How does the photo-based rehab estimator work?

Upload photos of the kitchen, bathrooms, and key rooms. The AI identifies condition and scope, then returns a room-by-room rehab budget using regional labor and material costs and your selected quality tier.

Fix and Flip Calculator — Every Number That Decides Your Profit

A profitable flip comes down to four numbers, and our fix and flip calculator nails all four:

ARV (After-Repair Value): What the home is worth fully renovated, derived from recent comparable sales in the same neighborhood and condition tier.
Rehab cost: A line-item renovation budget from kitchens and baths to roof, HVAC, and cosmetics — estimated from your uploaded photos.
Holding & selling costs: Financing interest, property taxes, insurance, utilities, agent commissions, and closing costs.
Net profit: ARV minus purchase price, rehab, holding, and selling costs — the money you actually keep.

Get any one of these wrong and a "good deal" turns into a loss. This calculator removes the guesswork so you make offers with confidence.

How the 70% Rule Protects Your Flip

The 70% rule is the flipper's safety net. It says you should pay no more than 70% of the ARV minus your rehab costs:

Maximum Allowable Offer = (ARV × 0.70) − Rehab Costs

Example: A property with a $300,000 ARV needing $50,000 in repairs gives a max offer of ($300,000 × 0.70) − $50,000 = $160,000.

That 30% buffer covers holding costs, selling costs, financing, and your profit margin. Our calculator runs the 70% rule automatically and lets you adjust the percentage for hotter or softer markets.

Why Investors Trust AI for Fix and Flip Analysis

Spreadsheets rely on numbers you type in — including an ARV you guessed. DealAnalyzerAI pulls real market data so your inputs are grounded in reality:

Comparable sales from multiple sources (Zillow, MLS feeds, Redfin, Realie)
Photo-based rehab estimates so your budget reflects the actual condition
Permit and market-risk flags that warn you about historic districts or flood zones
A deal score that benchmarks this flip against thousands of others

Spend your time on deals worth pursuing instead of building another spreadsheet.
