You found the house.

You’re under contract.

Now comes another decision:

**Do you lock your mortgage rate or wait?**

Here’s what matters:

**If your rate isn’t locked, it can move.**

Mortgage rates can change while you’re working toward closing. A rate lock generally protects an agreed-upon interest rate for a specific period, assuming you close within that window and important details of your application don’t change.

So the question isn’t really:

**“Are rates going up or down next week?”**

Nobody knows that with certainty.

The better question is:

**“Which risk am I more comfortable taking?”**

## What Is a Mortgage Rate Lock?

A mortgage [**rate lock**](https://www.consumerfinance.gov/ask-cfpb/whats-a-lock-in-or-a-rate-lock-en-143/) generally means the lender agrees to hold a particular interest rate for a specified period while your loan moves toward closing.

Typical lock periods may include **30, 45 or 60 days**, although options vary by lender and transaction.

If you close within the lock period and the information your loan is based on remains consistent, the lock generally protects you if market rates rise before closing.

But there’s another side.

If market rates fall after you lock, your locked rate does **not automatically drop with them**.

Policies vary by lender.

That’s why I want buyers asking about that **before** they lock.

## What Happens If You Float Your Rate?

Then your rate is **floating**.

That means the interest rate and pricing available to you can change before you eventually lock.

Maybe the market improves.

Maybe it gets worse.

That’s also why headlines about the [**Fed and mortgage rates**](https://voce.com/@jenniferchicano/fed-rate-hike-mortgage-rates-471hfn) don’t tell you exactly what your individual rate will do next.

**Waiting is still a decision.**

You’re exchanging certainty today for the possibility that something better may become available later.

That can work in your favor.

It can also work against you.

## Your Loan Estimate Tells You Whether You’re Locked

This one is easy to miss.

Receiving a [**Loan Estimate**](https://www.consumerfinance.gov/owning-a-home/compare/review-loan-estimates/) **does not automatically mean your rate is locked.**

Look at the top of page one.

It will tell you whether the rate is locked and, if it is, when the lock expires.

**Loan Estimate received ≠ rate locked.**

That little box matters.

## What Happens If Closing Gets Delayed?

Now the length of the lock becomes important.

If your rate lock expires before you close, extending it may come with a cost depending on the lender and circumstances.

That’s why I don’t want you choosing a lock period based only on what looks cheapest today.

I want it to make sense for the **actual closing timeline.**

## Can a Locked Rate Still Change?

Potentially.

A rate lock generally assumes important details about the loan stay consistent.

Changes involving things like your loan amount, down payment, credit, verified income or loan program can potentially affect your terms even after you lock.

That’s one more reason I keep telling buyers:

**Don’t make** [**major financial moves before closing**](https://voce.com/@jenniferchicano/what-not-to-do-before-mortgage-closing-b9bvr) **without asking first.**

## Before You Lock, Ask These Five Questions

**1\. What is my rate and pricing if I lock today?**

**2\. How long does the lock last?**

**3\. Does that comfortably cover my expected closing date?**

**4\. What happens if closing is delayed and the lock expires?**

**5\. What happens if rates improve after I lock?**

Now you’re making the decision based on **your mortgage**, not somebody’s rate prediction on social media.

## The Better Question

Don’t ask only:

**“Do you think rates are going down?”**

Ask:

**“Does locking today give me a payment and financing structure I’m comfortable moving forward with?”**

If it does, certainty may have value.

If you choose to float, understand what you’re risking in exchange for the possibility of something better.

**That’s the decision.**

If you’re under contract and trying to decide whether to lock or float, I can walk you through the rate, payment, pricing and timeline so you understand exactly what you’re choosing.
