MortgageRatelockedComparator
Tracks when mortgage rates lock in across lenders and alerts homebuyers if they missed better rate windows, helping them negotiate rate-match clauses before closing.
The Problem
Homebuyers lock in mortgage rates days or weeks before closing, but rates fluctuate constantly and lenders don't proactively notify them of better opportunities. Most buyers don't know they can request rate matches or have limited visibility into whether they got a competitive rate at their specific lock-in moment.
Target Audience
Real estate agents, loan officers, and homebuyers in active purchase transactions (roughly 5M+ annual US transactions)
Why Now?
Mortgage rate volatility has increased; AI makes it cheap to process lender rate feeds and alert users in real-time; agents are desperate for tools to reduce buyer regret and close deals
What's Missing
Existing rate comparison tools show current rates but don't timestamp when rates changed or let users see what rate they could have locked in on their specific closing date. Lenders have no incentive to show this data.
