It does not guarantee the lowest rate: if market rates fall, you may keep the higher locked rate, and a delayed closing can mean paying to extend the lock. Recent rate increases alone do not show that rates will keep rising. Check the lock’s terms and timing with your lender before deciding.
What the recent rate increase does—and does not—tell you
Freddie Mac reported an average 30-year fixed mortgage rate of 7.28% and a 15-year fixed rate of 6.60% on October 1, 2026. Its 30-year average was 7.03% on September 24 and 6.65% on August 20, showing a recent increase but not establishing what rates will do next. Freddie Mac’s survey data is not a forecast.
Those averages describe conventional, conforming, fully amortizing home-purchase loans for borrowers with 20% down and excellent credit. They are not a quote or guarantee for an individual buyer; your credit, loan details, lender, and market timing can result in a different offer. Freddie Mac explains the survey.
Freddie Mac Chief Economist Sam Khater said on October 1, 2026, “With mortgage rates on their current trajectory, the housing market continues to be supported by favorable economic conditions.” That comment concerns housing-market conditions; it should not be read as a prediction that mortgage rates will continue to rise.

What a mortgage rate lock actually protects
A rate lock is an agreement to hold your interest rate between the offer and closing, provided you close within the stated period and your application does not change in ways specified by the lender. CFPB says locks are commonly available for 30, 45, or 60 days, sometimes longer; terms and policies vary by lender. CFPB’s rate-lock guide.
- If rates rise: A lock can protect the agreed rate during the lock period, subject to the contract’s conditions.
- If rates fall: You may remain at the locked rate instead of receiving the lower market rate. A float-down option, if offered, is lender-specific; confirm its conditions in writing. CFPB explains rate-lock tradeoffs.
- If closing is delayed: Your lock may expire before closing. An extension may be available and may cost money; ask who pays and how the fee is calculated. CFPB’s Loan Estimate guidance and guidance on choosing a loan offer.
Check whether your rate is locked—and when it expires
Do not assume that receiving a Loan Estimate means your rate is locked. Lenders differ: some lock when they issue the estimate, while others do not. On page one of the Loan Estimate, check whether the rate is locked and the lock’s expiration date and time. Review any conditions that could affect the rate. CFPB: Review your Loan Estimate.
A lock can still be affected by application changes. CFPB examples include changes to the loan amount, credit score, verified income, loan type, down payment, appraisal, or documentation. Ask the lender which changes matter under your agreement. CFPB’s rate-lock guide.
How to decide whether to lock
- Confirm the offer and status. Review page one of the Loan Estimate for the locked rate, expiration date and time, and applicable conditions. If anything is unclear, ask the lender to explain it before relying on the lock. CFPB Loan Estimate guidance.
- Compare equivalent offers. Ask multiple lenders for the same kind of loan. Compare each Loan Estimate’s rate, points or lender credits, lock status, and lock duration rather than comparing rates alone. CFPB guidance on comparing Loan Estimates.
- Match the lock to your closing timeline. Ask how long the lock lasts and what happens if closing is delayed, including whether an extension is available, its cost, and who pays. CFPB Loan Estimate guidance and loan-offer guidance.
- Price the alternatives. Ask whether a shorter or longer lock changes the rate, points, lender credits, or fees, and whether locking has a charge. The Loan Estimate may not show the cost of extending a lock or the price difference for another duration, so ask directly. CFPB’s rate-lock guide and Loan Estimate guidance.
- Clarify what happens if rates fall or your application changes. Ask whether a float-down is available, what conditions apply, and which changes could affect the locked rate. CFPB’s rate-lock guide.
- Choose based on the actual terms and your comfort with risk. If certainty through your likely closing date matters more to you than the possibility of savings if rates fall, you may value a lock. If you are comfortable with rate movement and understand the risk, floating may be acceptable. This is a way to weigh the tradeoffs, not a prediction of rates or individualized financial advice.
