Appraisal Risk Gate

The value supported by comparable sales.
Most conventional loans allow up to 80% financing.
Extra cash you can bring to close if the appraisal is lower than your offer.
Appraisal gaps are one of the most common reasons deals collapse after contract. Run this simulation to see if your structure survives lender underwriting rules.
Tip: Try a deal that already closed to verify the math.
Demo access allows 3 deal evaluations. Investor access unlocks 20 evaluations per day.
How this analysis works

Banks calculate loan proceeds using the lower of purchase price or appraised value. If the appraisal comes in below your offer, the lender reduces financing and the buyer must cover the difference. SignalGate applies this lender rule to determine whether your deal structure survives if appraisal aligns with comparable sales. This tool does not predict appraisal outcomes. It evaluates structural survivability based on your inputs.
Simulation uses standard residential lending mechanics (LTV-based underwriting).
