ARV Validation
Comparing your estimated ARV against comp-derived and county-assessed values.
ARV validation is the process of cross-checking your after-repair value estimate against external data. This includes comparable sales from the market, county assessed values from GIS data, and historical ARV accuracy from your own completed deals. An ARV that significantly exceeds all reference points is a warning sign — either you know something the market doesn't, or your estimate is optimistic.
When GIS data is available, Kaison compares your ARV against the county's market value. The variance learning system also tracks how accurate your ARV estimates have been on past deals. If you consistently overestimate ARV by 8%, the engine flags that pattern.
You estimate ARV at $250,000. County market value is $195,000. Comps suggest $235,000-$260,000. The county value is pre-rehab, so the gap makes sense. But if comps only support $230,000, your $250,000 ARV may be aggressive.
