Every wholesale deal lives or dies on the accuracy of the After Repair Value (ARV) calculation. Overestimate the ARV and you overpay for the property. Underestimate it and you lose deals to competitors who can offer more.
Manual ARV calculation — pulling comps from MLS, adjusting for square footage, condition, and location — takes 30-60 minutes per property and is prone to human error. At scale, this becomes the primary bottleneck in wholesale operations.
Modern wholesale automation engines calculate ARV automatically using:
1. Comparable Sales Analysis The engine pulls the 5 most recent comparable sales within a defined radius, filtered by square footage range, bedroom/bathroom count, and property type. Comps are weighted by recency and proximity.
2. Automated Adjustments The system applies standard adjustments for square footage differences, lot size, garage, pool, and condition. Adjustment values are calibrated to local market data.
3. Condition Scoring Property condition is estimated from listing photos, permit history, and age of major systems. The engine assigns a condition score that adjusts the ARV downward for properties requiring significant work.
4. Market Trend Adjustment In rapidly appreciating or depreciating markets, the engine applies a trend adjustment to account for the time between comp sales and the current valuation date.
Once ARV is calculated, the Maximum Allowable Offer (MAO) is computed automatically:
MAO = (ARV × 0.70) - Estimated Repair Costs - Assignment Fee
The engine enforces minimum assignment fee thresholds. Any deal where the MAO falls below the seller's asking price is automatically rejected before outreach begins.
Automated valuation systems must include guardrails to prevent bad deals from advancing:
Well-configured automated valuation systems achieve ARV accuracy within 5-8% of actual sold prices in stable markets. In volatile or thin markets, accuracy decreases and manual review thresholds should be tightened.
The valuation step should be triggered automatically when a lead responds positively to outreach. The system should:
OptiFlow Tools' valuation engine handles all of this automatically, with operator review required only for deals flagged as edge cases.
