How to Calculate ARV for Wholesale Real Estate Deals

After-repair value — ARV — is the single most important number in any wholesale real estate transaction. Get it right and everyone in the deal makes money. Overestimate it and your cash buyer will never close, or worse, will close and lose money, killing your reputation in the process. Every wholesaler needs a disciplined, repeatable process for estimating ARV before making an offer.

What Is ARV and Why It Matters

ARV is the estimated market value of a property after all planned renovations are complete. It answers the question: "What will this house sell for when it's retail-ready?" Your cash buyers — fix-and-flip investors — use ARV as the baseline for their entire deal math. They typically follow the 70% rule: they won't pay more than 70% of ARV minus estimated repair costs. Your wholesale fee must fit inside that spread. A solid ARV estimate ensures you price your contracts competitively and protect every party's profit.

Pulling Comparable Sales (Comps)

Comps are recently sold properties similar in size, condition, age, and location to your subject property after renovation. Use MLS data (via an agent partner), Zillow's sold listings, or county tax records. Look for sales within 0.5 miles (expand to 1 mile in rural areas), similar square footage (within 10–20%), same bedroom/bathroom count, and sold within the last 90 days. Distressed or REO sales should generally be excluded — you want fully renovated retail comparables. Average the price per square foot of 3–5 good comps and multiply by your subject property's livable square footage.

Adjusting Comps for Property Differences

Raw comp averages rarely tell the whole story. You need to adjust for differences between each comp and your subject property. A comp with a garage adds value if your property lacks one; a comp without updated kitchen finishes may understate value if your rehab includes that upgrade. Industry standards suggest $10,000–$20,000 adjustments per bedroom difference, and $5,000–$15,000 for garage presence or absence. Keep adjustments conservative — buyers will run their own numbers and aggressive ARVs erode trust quickly.

Applying the 70% Rule to Set Your Offer

Once you have a confident ARV, the 70% rule gives you a quick maximum allowable offer (MAO) framework: MAO = (ARV × 0.70) − Repair Costs − Wholesale Fee. For example, if ARV is $250,000, repairs are $40,000, and you want a $15,000 assignment fee, your MAO is ($250,000 × 0.70) − $40,000 − $15,000 = $120,000. This leaves your end buyer with a comfortable margin. Never stretch past these numbers hoping a buyer won't notice — experienced investors run tighter math than you expect.

Tools and Resources for Faster ARV Research

Professional-grade tools like PropStream, DealMachine, and BatchLeads integrate MLS sales data and let you pull comps in minutes. Many wholesalers also partner with a licensed real estate agent who provides free CMA (comparative market analysis) reports in exchange for referral deals. Building this network early in your career dramatically speeds up the due diligence process and improves your accuracy on every offer you submit.

Mastering ARV calculation separates casual wholesalers from consistent deal-closers. A disciplined comps process protects your buyers, your reputation, and your bottom line.
