"you ready to lock this in?" - pressuring loan officer

"I don't know, I need more time" -you

"Rates change every day, it could get way worse tomorrow"

"Yeah, but I don't know if I want to buy down the rate or not, or if another lender is offering anything better"

"Rates could get worse while you're mulling it over, then I won't be able to get this deal for you. I'm telling you it's a deal and no one can beat it. But tomorrow it won't be available."

"Okay, fine, lock it in"

You hang up the phone and think 'that didn't go as planned.'

Are you stuck with this lender now?

I want people to know ahead of time how this works, so they don't feel stuck

Here's what I'll cover:

• What does locking a rate do?
• Can you pivot between your locked rate, and a rate with a buydown?
• What is a 'float down'?
• Can you work with a different lender despite having locked in the rate?

I'm borrowing some content I've posted previously.

What is a rate lock?

When you lock your rate, your lender is basically saying: “We’ll honor this interest rate even if the market changes.”

Most locks are good for 30-60 days, sometimes longer if you're building a home.

Why lock? Because rates can jump unexpectedly. A rate lock gives you some peace of mind. You can budget around a predictable payment, even if rates spike next week.

This allows you to get your financing in order with a predictable payment and closing costs.

Floating vs locking

If you don’t lock, your rate is “floating,” which means it moves with the market. This is riskier but can pay off if rates drop. You’re gambling. If they go up? You’re stuck paying more.

Floating might make sense if you think rates will drop and you’re not closing super soon. Otherwise, locking is usually the safer play.

Can I change my rate after I lock it?

Yes.

When you lock, you’re usually locking in a menu of options, or the rate table, not just one rate.

That menu (aka a “rate sheet”) includes higher rates with lender credits (help cover closing costs), and lower rates that cost more upfront (called points).

You can still switch between these choices later, you're not stuck with the exact rate you picked, as long as you stay on the same rate sheet.

Example:

• 6.375% = $2k lender credit (less cash at closing, higher monthly payment)
• 6.125% = you pay $6k in points (more cash now, lower monthly payment)

It’s all about trade-offs.

The key is to run the break-even math. If it takes you 5 years to save back the upfront cost in monthly payments and you’re moving in 3, then don’t bother with points.

Here's a break-even calculator for you.

You can usually pivot between different rates on the rate sheet you locked, but make sure you do it with advance notice. Maybe 2 weeks before at the latest.

What is a float-down?

A float-down is like a “just in case” clause. If you lock at 6.5% and the market drops to 6.0%, a float-down lets you grab the lower rate, usually one time.

It’s not always free.

Some lenders charge for it (flat fee or a small percent of the loan), and some only offer it if rates drop by a certain amount.

Ask your lender:

• Do you offer float-downs?
• How much does it cost?
• When can I use it?
• How far do rates need to drop?

Not all lenders offer this, so ask early.

Can I change to a new lender after locking?

Yes.

In that first example, let's say you lock in a rate with a lender and say "let's proceed." But then the next day a loan officer brings an offer that is way more compelling. Can you take it?

Yes.

Just because a loan officer pressured you into locking, it doesn't mean you can't continue to shop lenders.

I'd get your shopping done with in the first few days of your contract, otherwise you could go weeks into the process and not make any progress.

Decide, and decide quick. (2-3 days)

Locking is a sort of 'free insurance' if you want to look at it like that.

It can't get worse than what you've locked. It can only get better.

A mortgage broker actually does this frequently.

They lock with one lender.

Rates get better.

That lender doesn't allow float-downs

Then the broker takes your loan to a new lender.

The lender that locked first will get upset, and it damages the broker-lender relationship. But it happens a lot.

What I tell people

Once we get to 2 weeks before closing, I tell buyers to put their blinders on. It's probably not worth the risk of breaking your contract because you heard rates dropped 0.25%

Two weeks out, keep your eye on the prize (the house).

Exception: The loan officer should keep an eye on rates. If it's a week out and there's a chance for a float-down, I'd take that one. Just not changing or transferring lenders.

Real-world story: When rates kept dropping

I had clients who locked in a solid rate. Then rates fell. Good news, they had a float-down and used it.

Then rates fell again. Their lender didn’t offer a second float-down, so we switched lenders mid-process. Risky, but the savings were worth it.

Then rates dropped again. The new lender let them float-down again.

End result: multiple float-downs, new lender, huge savings. Not typical, but a good reminder, understanding your options matters.

Final thought

Rate locks aren’t just paperwork. They’re a strategy. Know your lender’s rules, ask smart questions, and make sure you’re locking in flexibility, not just a number.
