Rate lock
A lender commitment to hold a specific interest rate for a set period (typically 30–60 days) while your loan is processed and underwritten. If rates rise during the lock, yours stays the same. Some lenders offer float-down options that allow you to capture a rate improvement after locking.
How does this affect your loan? Estimate self-employed qualifying income with the DTI calculator, or read the self-employed mortgage guide.
