How to Shop Mortgage Rates (Without Getting Played)

By OfferPrep Editorial · Last reviewed October 24, 2026 · 7 min read

The short version

1. Know what moves your price before anyone quotes you.
2. Pick one scenario (loan type, term, amount, down payment, occupancy) and give every lender the same one.
3. Request Loan Estimates the same day, inside the CFPB's 45-day credit-shopping window.
4. Compare Section A plus points or credits, not the headline rate.
5. Decide on points with break-even math, not a gut feeling.
6. Lock on purpose: right length, extension terms in writing.

Part 1: How a mortgage rate is priced

There isn't one "today's rate." Lenders start from market pricing and adjust it for risk and features. The biggest levers:

The takeaway: an ad's rate assumes someone else's scenario. Your number only exists once a lender prices your scenario. The CFPB's explore interest rates tool shows how these levers interact.

Part 2: Rate vs. APR

• Interest rate: sets your monthly principal and interest.
• APR (annual percentage rate): folds in certain costs, such as points and some lender fees, and expresses the total as a yearly rate.

When two offers have similar rates but different APRs, the higher APR usually signals more upfront cost. APR assumes you keep the loan for its full term, so it's a comparison tool, not the whole story.

Part 3: Points vs. lender credits, with a worked example

• Discount points: money you pay at closing to lower the rate. One point equals 1% of the loan amount.
• Lender credits: money the lender puts toward your closing costs in exchange for a higher rate.

Worked example. Made-up numbers for illustration only. Not a quote and not current market pricing.

Break-even for Option 2: $3,000 ÷ $50 = 60 months (5 years). If you'll likely sell or refinance before year 5, the point probably doesn't pay off.

Option 3: you keep $2,000 now and pay $35 more each month. $2,000 ÷ $35 ≈ 57 months. Keep the loan longer than that and the credit costs more over time; shorter, it may come out ahead, and it leaves more cash in your pocket at closing.

Part 4: Lender fees vs. third-party fees

On page 2 of the Loan Estimate:

• Section A, origination charges: the lender's own fees, including points. This is where lenders differ most. Compare it line by line.
• Section B, services you cannot shop for: the lender picks the provider (for example appraisal, credit report, flood certification).
• Section C, services you can shop for: often title and settlement services. The lender gives you a list, and you may be able to choose others.
• Sections E–H: taxes, government fees, prepaids, and escrow. These mostly depend on the home and closing date, not the lender, so they shouldn't decide your comparison.

Tip: a lower Section C may just mean a lower estimate. Center your comparison on Section A plus points or credits.

Part 5: The same-day, same-scenario method

1. Write down one scenario: loan type, term, fixed or ARM, price, down payment, loan amount, occupancy, property type, and estimated closing date.
2. Choose two or three licensed lenders you found yourself. Check licenses at nmlsconsumeraccess.org.
3. Ask for an official Loan Estimate, not a worksheet or a text message. A lender must send one within three business days of receiving your application.
4. Request them the same day, ideally the same morning. Pricing changes daily, sometimes more often.
5. Ask each for the same structure, for example "no points," so you compare like for like. Then ask what one point or a credit would change.
6. Line them up on the worksheet below.

Part 6: The 45-day credit window

Worried that several credit checks will hurt your score? According to the CFPB, within a 45-day window, multiple credit checks from mortgage lenders are recorded on your credit report as a single inquiry. So compare in a tight window rather than spreading it over months.

Part 7: When to lock, and for how long

• Lock or float: floating means your pricing can move until you lock. A lock trades possible upside for certainty. Nobody can reliably predict rates, and OfferPrep doesn't try.
• Common timing: many buyers lock once they have an accepted contract and a closing date.
• Length: match it to your closing date plus a cushion. Longer locks may cost more.
• Extensions: ask the cost up front, and who pays if the delay is the lender's.
• Get it in writing. Your Loan Estimate shows whether the rate is locked and until when.

Float-down basics

Some lenders offer a float-down: if market pricing improves after you lock, you can take the improved pricing, often once and with conditions (a minimum improvement, a fee, or a time window). Ask whether it's offered, what triggers it, and what it costs.

Part 8: Questions to ask every lender

1. Is this an official Loan Estimate for my exact scenario?
2. What's in Section A, and can any of it be reduced?
3. Does this pricing include points or lender credits?
4. What would one point, or a credit, change?
5. What lock period is this priced for? What does an extension cost?
6. Is there a float-down option?
7. Which Section C services can I shop for?
8. Are you a direct lender or a broker?

See all 20 questions to ask any lender.

Part 9: Red flags

• A quote that won't come as an official Loan Estimate.
• A "rate" with no mention of points, credits, or lock period.
• Pressure to sign or pay a fee before you've received a Loan Estimate.
• Pricing that changes after lock without a change in your scenario.
• Anyone discouraging you from comparing.
• Urgent emailed wire instructions. Always verify by phone at a number you looked up yourself.

Part 10: Your comparison worksheet
