Deal Status
You're within the 70% rule. Max offer is $205,000 — your price of $200,000 is good.
Analysis & insights
Based on the 70% rule, your max offer is $205,000. Projected profit at that price: $92,000 (35.7% ROI). The numbers support the deal — but verify ARV with 3+ recent solds within 0.5 miles, and add 15% to your repair estimate as a buffer.
Strong flip margin
35.7% ROI on a flip is well above the typical 15-20% target. Move quickly if comps support the ARV.

Key insights
The 70% rule explained
Max offer = (ARV × 0.70) − repairs. The 30% spread covers holding costs, transaction costs, and your profit margin. Going above 70% means you're lending the seller money.
Repair estimates always under-shoot
Surprise: bad framing, hidden water damage, electrical/plumbing issues, foundation, roof. Pad your contractor estimate by 15-25% before signing.
ARV depends on 3+ verified comps
Single-comp ARVs lie. Need 3+ recent (90 days) sold comparables within 0.5 miles, similar size/beds/baths, in similar condition AFTER renovation.
Recommended actions(4)
Get 3+ ARV comps from a local agent
High priorityPull recent sold comparables that match your post-renovation specs. Don't use online estimates (Zillow, Redfin Zestimate) — they're backwards-looking and miss condition.
Add 15-25% to your repair estimate
High priorityGet 2-3 contractor walkthroughs. Take the highest estimate × 1.15 as your true budget.
Plan for 6-9 months of holding costs
Medium priorityLoan interest, utilities, insurance, taxes during renovation + sale. Many rookie flippers omit this.
