Float-Down

Defined by Onias Derilus, Mortgage Capital · NMLS# 1859012 · Florida licensed mortgage broker

A float-down is an option that lets a borrower capture a lower rate if market rates fall during an existing rate lock.

What Float-Down means

It provides downside protection on top of the lock, usually for a fee. If rates drop meaningfully before closing, the borrower can reset to the lower rate once.

Florida example

A Florida borrower locks at 6.875% with a float-down option. When rates dip to 6.5% before closing, they exercise the float-down and close at the lower rate instead of the locked one.

What it is

A float-down lets you lower your locked rate if market rates drop before you close. It gives you a one-time chance to improve your rate.

There may be a fee or set rules to use it.

Why it matters

A float-down protects you if rates fall after you lock. You get the safety of a lock with some upside.

We explain float-down options up front. Reach out and we will help you lock with confidence.
