Buying a home is as much about timing as it is about dollars and cents. One decision that can make or break your financing is when (or whether) to lock in your mortgage interest rate. Think of it like reserving a price on that big purchase you’ve been eyeing — in a volatile market, that reservation can offer peace of mind or backfire if you lock too soon.
In this post, we’ll walk you through:
- What rate locks (or rate holds) are, and how they work
- The pros and cons of locking early vs waiting
- Key signs that it’s the right moment to lock
- Mistakes to avoid
What Is a Rate Lock (Rate Hold)?
A mortgage rate lock (also called a rate hold) is an agreement between you and your lender that secures a specific interest rate for a limited time, no matter how market rates move during that period.
During the lock period:
- If interest rates rise, you are protected — you still get the rate you are locked in.
- If they fall, depending on your lender, you may be able to “float down” to a lower rate (if your lender allows it).
- But once the lock expires, you lose that guarantee and must take whatever current rates prevail (if your mortgage hasn’t closed yet).
Why You’d Consider Locking Early — The Benefits
- Protection from rate increases: If market rates trend upward while your mortgage is still in process, a rate lock shields you from those spikes. That certainty can save you hundreds of dollars per month, especially on large mortgages.
- Budget confidence and peace of mind: Knowing your rate ahead of time lets you plan your monthly payments, cash flows, and closing costs without fearing last-minute surprises.
- Longer timelines accommodated: Sometimes your closing or possession dates stretch out. A longer lock helps bridge those gaps.
- Locking in a favorable rate: If rates are low or your lender is offering a strong promotional rate, locking early ensures you capture it before it vanishes.
The Risks of Locking Too Early or at the Wrong Time
Of course, it’s not always wise to lock immediately — there are trade-offs and pitfalls.
- You might miss out on lower rates – If rates fall after you lock and your lender doesn’t allow a float down, you’re stuck with the higher rate.
- Short lock periods can expire – If your closing is delayed and your lock expires, you may need to renegotiate at a higher rate.
- Lock fees and premiums – Some lenders charge fees or build a small premium into long lock periods.
- Changes to your application may void the lock – A new job, added debt, or a different property may affect the rate.
- Waiting too long can also backfire – If you hold off and rates jump, you lose the chance to secure a lower rate.
Signs It’s the Right Time to Lock
- Rates are volatile and trending upward.
- You’ve finalized your property and financing details.
- Your closing date is within the lock period offered.
- Market indicators suggest rates will rise.
- You prefer peace of mind over chasing every possible dip.
- Your lender provides a float-down feature.
When You Might Not Lock Right Away
- Market experts predict rates will fall further.
- Your closing date is uncertain and far away.
- Longer locks come with higher costs or conditions.
- You’re comfortable monitoring rates and taking a little risk.
Example: Locking vs Waiting
Suppose you’re purchasing a home with a $500,000 mortgage. You lock a 5-year fixed rate at 4.50% today, with closing in 90 days.
- If rates rise to 5.00% before closing, your lock saves you hundreds monthly.
- If rates fall to 4.25% and your lender doesn’t allow a float-down, you miss out on savings.
It’s a trade-off between security and opportunity.

Final Thoughts
There’s no perfect moment to lock your mortgage rate. It depends on your comfort with risk, your closing timeline, and the direction of rates. Locking early can give peace of mind, while waiting can sometimes save money if rates dip.

FAQs About Mortgage Rate Locks
Most lenders allow 30 to 120 days, but some extend up to 150 days depending on the product and institution.
Not always. Some lenders offer them free, while others may add a small premium or fee for longer locks.
If your lender offers a float-down feature, your rate remains fixed at the locked amount; otherwise, it stays the same.
If your lock expires, you may need to extend it (sometimes with a fee) or renegotiate at new market rates.
No. A rate lock secures your interest rate, but you still need to qualify based on credit, income, and property details.
