Find the lease deals captives are mispricing this month.
ResidualCheck scores every active lease program against an independent residual projection — so you see which deals are mathematically generous before the program changes.
Independent math on every program.
Track every program
Every captive lease program nationally — residuals, terms, and money factors as they're published.
Project natural residuals
Independent projections built from real auction and listing data for the same model, term, and mileage.
Surface the gaps
Where the captive's number sits above the market's, that's subsidy you can use — before it expires.
Every projection shows its work.
No black box. Each check lists the exact sold and listed comparables behind the projection — VIN, mileage, price — with a confidence score based on how many comps support it.
