Underwriting Formula & Offer Methodology

The 70% Maximum Allowable Offer (MAO) Rule

Widely used by professional real estate investors, flippers, and wholesale acquisitions teams. The baseline formula calculates purchase ceiling as: MAO = (ARV × Target Factor) − Estimated Rehab − Wholesale Fee. The target factor accounts for holding costs, mortgage debt service, selling commissions (typically 5-6%), and risk buffer.

Comparable Adjustments & Distance Decay

Comps within 0.5 miles with similar square footage (within ±20%) and closed within the past 180 days receive highest weighting. Adjustments normalize for square footage variance (typically $90–$140/sqft base adjustment) and structural improvements to establish after-repair value (ARV).
