Three browser tabs, three different numbers. One lender shows 6.25%, an aggregator shows 6.51%, and a bank’s homepage promises “rates as low as 5.99%.” All three were accurate on the morning you looked. None of them is your rate.
That gap is the whole game. Checking current mortgage rates isn’t about finding one true number, because there isn’t one. It’s about reading the quotes you find correctly, understanding which of your own details move the pricing, and getting an actual offer that reflects your house, your credit, and your down payment.
Why the advertised rate and your rate are rarely the same
A mortgage rate is built from a base cost of money plus a stack of adjustments for risk. Lenders price in your credit score, the size of your down payment, whether the home is a condo or a single-family house, whether you’ll live there or rent it out, and how long you want the rate locked.
Advertised rates sit on the cheapest possible version of that stack: perfect credit, 20% down, owner-occupied, single-family, no lock, and often with discount points baked in that you’d have to pay for out of pocket. The national average mortgage rate quoted in the news is a survey response, not a price list.
None of that makes the headline number a lie. It makes it an advertisement priced for a borrower who is not you.
Where to check rates, and what each source is actually good for
Different sources answer different questions. Use them in the right order and you’ll waste far less time.
- Freddie Mac’s Primary Mortgage Market Survey lands every Thursday and covers a 30-year fixed national average. It’s a trend line, not a shopping tool. Checking it weekly tells you which direction pricing is drifting.
- Rate aggregators like Bankrate, NerdWallet, and Zillow show a spread of offers from multiple lenders on the same day. That spread, often 0.5 to 0.75 percentage points, is the most useful thing they give you.
- Lender and bank websites publish rates next to a long list of assumptions. Read the assumptions before you read the number. Many require a 740+ score and 25% down to get the rate shown.
- Local banks and credit unions still post rate sheets with a date stamp, and they’re often competitive on jumbo or portfolio loans.
- A mortgage broker will pull pricing for your actual scenario across several wholesale lenders. This is the only source on the list that produces a real number for your situation.
Watch for the teaser trap
The gap between an advertised quote and a real offer is where a lot of first-time shoppers lose money. A rate promoted at 5.99% frequently comes with 2 points and a 21-day lock, which means the number only exists if you pay roughly $6,000 on a $300,000 loan and close fast. Understanding why the mortgage quote you see isn’t the one you get saves you from a very unpleasant conversation at the closing table.
The five inputs that decide your actual rate
Credit score
This is the single biggest lever. On a conventional loan, moving from a 660 to a 760 score can cut your rate by close to a full percentage point, which on a $350,000 loan is roughly $230 a month. Worth knowing exactly what a 760+ score actually buys you in rate pricing before you assume you’re already at the bottom.
Down payment and loan-to-value
Crossing 80% LTV removes mortgage insurance and usually improves pricing. Smaller down payments aren’t automatically expensive, either. 3% down conventional loans carry pricing adjustments that are often smaller than people expect, especially with strong credit.
Loan type, term, and property
A 30-year fixed is priced differently from a 15-year, an ARM, an FHA loan, or a jumbo. Condos with high investor concentration, second homes, and investment properties all carry add-ons that never show up in a headline rate.
Points and lender credits
A rate quote with no context is meaningless. One point (1% of the loan amount) typically buys about 0.25% off the rate. Lender credits work the other way: a slightly higher rate in exchange for cash toward closing costs.
Lock length
A 30-day lock costs less than a 60-day lock. If you’re 45 days from closing and you’re quoted a 30-day rate, you’re being shown something you can’t actually have.
Ask for a Loan Estimate, not a quote
Any lender can quote you anything over the phone. The Loan Estimate is a standardized three-page form that every lender must send within three business days of a completed application, and it’s the only document that lets you compare offers honestly. Pull two or three of them on the same day and line them up:
- The interest rate and the APR, which folds in fees
- Section A (origination charges) and Section B (services you cannot shop for)
- Lender credits, if any
- Estimated cash to close
- Whether the rate is locked, and until when
A rate that’s 0.125% lower with $4,000 in extra fees can be the more expensive loan if you plan to move in five years. Break-even math settles that argument faster than any sales pitch.
When you check matters
Rates move daily, sometimes twice, and they respond to Treasury yields, Federal Reserve commentary, and inflation data. Two patterns are worth building into your routine. Pricing is often worst on Monday mornings and improves later in the week as lenders compete for volume. And the morning a major economic report drops is not the moment to lock. Watching what mortgage rates are doing right now across a two-week window gives you a realistic sense of volatility instead of a single anxious snapshot.
If your closing is more than 60 days out, you have room to watch. If it’s inside 30 days, you’re choosing between locking and paying for a float-down option, not between waiting for a better week.
Three questions to ask before you trust any number
When you’ve got a rate in front of you, ask the loan officer three things. What credit score and down payment is this rate priced for? Are points included, and how much are they in dollars? How long is the lock, and what happens if we close late?
The answers turn a marketing number into a real offer in about ninety seconds. If the person on the phone can’t answer all three clearly, that tells you something too.
One last piece of practical advice: get your quotes within a 14-day window. Credit scoring models treat multiple mortgage inquiries inside that period as a single event, so shopping five lenders won’t dent your score. The only thing comparison shopping costs you is time, and the spread between the best and worst offer on the same day is usually worth several thousand dollars over the life of the loan.
