A mortgage rate lock protects you from rising interest rates by freezing your loan rate for a fixed period while your home loan is processed. If market rates climb before closing, your locked rate stays the same. Most rate locks last 30 to 60 days, with longer options available. Locking at the right time brings peace of mind and shields your monthly payment from sudden surprises.

A home loan is not just a financial decision. It is an emotional milestone. Somewhere between the first property visit and the final signature, interest rates can quietly shift.

This guide explains mortgage rate locks in plain language, with clarity, data, and calm confidence so you can decide wisely.

What is a mortgage rate lock, and why does it matter?
A mortgage rate lock is an agreement between you and a lender that keeps your interest rate unchanged for a specific period. It matters because even a small rate increase can add thousands of ₹ over the life of your loan.
Once you lock your rate, the lender commits to honoring it as long as you close on time and avoid major application changes. If rates rise, you are protected. If rates fall, you may feel regret unless your lender offers a float-down option.
In emotional terms, a rate lock is stability. It transforms uncertainty into predictability. Your future payment becomes a known number rather than a moving target.

What causes mortgage rates to change so often?
Mortgage rates change due to inflation trends, central bank policies, bond market movements, and overall economic confidence.
Beyond the economy, your personal profile also matters. Credit score, loan amount, down payment, and loan type all influence the rate you are offered.
| Factor | Impact on Mortgage Rates |
|---|---|
| Inflation | Higher inflation pushes rates upward |
| Central bank policy | Tighter policy usually raises rates |
| Credit score | Higher score qualifies for lower rates |
| Loan type | Fixed rates differ from adjustable loans |
How does a mortgage rate lock actually work?
After choosing a lender, you request a rate lock for a set period, commonly 30, 45, or 60 days. The lender then guarantees that rate until closing.
To keep the lock valid, you must close within the lock window and avoid material changes such as switching loan programs or altering income details.
Typical initial lock periods include:
- 30 days
- 45 days
- 60 days
- 90 days
If delays occur, you may extend the lock for a fee. The longer the extension, the higher the cost.
What happens if mortgage rates fall after you lock?
If rates fall after locking, you usually keep your original rate unless your lender offers a float-down option.
A float down allows you to capture a lower rate if market rates drop by a specific margin. This option often costs extra and comes with conditions.
Without a float down, you can still switch lenders if you find a better deal. A rate lock does not legally bind you to complete the loan.
Does locking your rate tie you to one lender?
No. A mortgage rate lock does not force you to close with that lender.
If another lender offers better terms, you are free to walk away. The only potential loss is any upfront lock fee you paid, which many lenders do not charge.
This flexibility empowers borrowers. Your loyalty belongs to your financial well-being, not a single quote.
When is the best time to lock a mortgage rate?
The best time to lock is when you have a signed purchase agreement or a refinance offer that clearly saves you money.
Locking too early can lead to extensions. Locking too late exposes you to rate spikes. Timing depends on market trends and your closing timeline.
| Scenario | Recommended Action |
|---|---|
| Just browsing homes | Wait before locking |
| Offer accepted | Lock promptly |
| Refinancing | Lock when savings appear |
How much does a mortgage rate lock cost?
Most initial mortgage rate locks are free, with costs built into the interest rate.
Some lenders charge 0.25 to 0.50 percent of the loan amount. Extensions and float downs usually cost extra and are paid out of pocket.
Think of the cost as insurance. A small fee today can prevent decades of higher payments.
What are the pros and cons of locking your mortgage rate?
Locking protects you from rising rates but limits your ability to benefit if rates fall.
| Pros | Cons |
|---|---|
| Protection from rate increases | No benefit if rates drop |
| Payment certainty | Possible extension fees |
| Easier budgeting | Float down may cost extra |
