A lock feature that can improve pricing if market rates move lower.
Float down is a mortgage pricing feature that may let a borrower improve the terms of an existing rate lock if market pricing moves favorably before closing.
Float-down matters because borrowers often feel trapped when they lock and then see rates improve before closing. A float-down feature can reduce that frustration, but only if the lender offers it and the exact rules are understood.
It also matters because many borrowers misunderstand the term as a general right. Float-down is not automatic. It is a specific feature governed by lender policy, timing rules, and sometimes extra cost.
Borrowers encounter float-down after a Rate Lock is already in place. It becomes relevant only if market conditions improve before the mortgage closes.
The feature is most important late in the pre-closing period, when the borrower wants to know whether the locked terms are final or whether limited improvement is still possible.
| Feature | What it does | Borrower question |
|---|---|---|
| Rate Lock | Protects pricing against worse market moves for a defined period | Am I protected if rates rise before closing? |
| Lock Period | Defines how long that protection lasts | Will my transaction finish inside the protected window? |
| Float down | May allow limited improvement if pricing gets better | Can I benefit if the market improves after I lock? |
| Rate Lock Extension | Adds time if the file is running late | What happens if the lock is about to expire before closing? |
| Rate Float | Leaves pricing unlocked before a lock is accepted | What happens if I wait to lock? |
A borrower locks a mortgage rate, then sees market pricing improve before closing. If the lender’s lock terms include a float-down option and the borrower satisfies its rules, the final rate or point structure may improve from the original lock.
Float-down differs from Rate Lock because it is not the initial commitment itself. It is a possible adjustment feature attached to some locks.
It also differs from Lock Period. Lock period tells you how long the locked pricing lasts. Float-down tells you whether pricing can improve during that period.
It also differs from Rate Lock Extension. Float-down is about improving locked pricing if the market helps, while an extension is about preserving time protection when closing is delayed.
