Of all the moments in a Tampa Bay home purchase, the rate lock is the one that turns a floating estimate into your real monthly payment. Get the timing right and you save; get it wrong and you pay for decades. Here's how to think about it.
What a rate lock actually is
A lock is your lender's commitment to a rate and points for a set window - typically 30, 45, or 60 days - long enough to cover your contract-to-close timeline. Inside that window, market moves don't change your rate. Outside it, you either extend (often for a fee) or float with the market.
When to lock
- When you're under contract with a firm close date - lock to match your closing
- When rates are at or near a recent low - don't gamble on "lower" you may not get
- When your tolerance for risk is low - locking buys certainty, and that has value
When not to lock too early
Locking before contract burns a window you may need to extend. For most buyers, the right moment is shortly after an accepted offer, with a lock term that comfortably covers the close.
The float-down option
Some lenders (including the programs I work with) offer a float-down - if rates drop after you lock, you can take the lower rate. Ask about it; it's the best of both worlds when available.
What I do
I monitor rates for my clients daily between contract and close, and I call you the moment locking makes sense - not on autopilot. As your originator (NMLS #2857504), I treat your rate like it's my own payment.
