You saw a rate advertised online, then a lender quoted you something higher. The ad was not necessarily wrong. It was just describing a different borrower than you.
The advertised rate is usually a best case
An advertised rate is often built from the most favorable assumptions a lender can legally show: the top credit score tier, a specific down payment amount, and sometimes a point or more paid upfront to buy the rate down. If any one of your details does not match those assumptions, your real quote moves.
The CFPB calls this a kind of teaser rate, an advertised number built around the most favorable borrower profile, not a promise to any specific reader. It is not dishonest by itself, but reading it as your rate is the mistake.
What real borrowers actually paid in 2024
Instead of a hypothetical, here is what government loan data actually shows. CFPB’s HMDA data tracks closed conventional purchase loans by county. Look at three different counties from the same year, and the “one rate” idea falls apart fast.
| County | Median rate, 2024 | Median total loan costs |
|---|---|---|
| Harris County, Texas | 6.625% | About $7,076. |
| Los Angeles County, California | 6.875% | About $10,118. |
| Miami-Dade County, Florida | 6.99% | About $11,429. |
These are medians reported by real, closed loans in 2024, not a forecast of what you will pay. Different counties, similar time period, three different typical rates.
The spread inside a single county is real too
Even within one county, borrowers did not all pay the same rate the same way. In Harris County, Texas, about 53% of conventional purchase borrowers paid discount points to lower their rate in 2024, while about 30% received a lender credit instead, according to the same HMDA data. Those are two very different pricing paths landing on the same median rate. A borrower who paid points and a borrower who took a credit were not quoted “the rate,” they were quoted two different deals that both happened to average out near the same number.
Why does one advertised number hide all this?
Because an ad has to pick one number to show, and averages and best cases are what get published. Real closed loans, tracked by HMDA, show the actual range of outcomes: some borrowers paid to buy their rate down, some took a credit and accepted a higher rate, and the county median sits in the middle of all of it. That range is the honest picture. A single advertised rate is not built to show it.
What this means for you
Treat an advertised rate as a starting point, not your number. Your credit score, down payment, loan amount, county, and whether you choose to pay points all move your real quote away from that headline figure. Ask each lender for your rate at zero points and get it in writing on a Loan Estimate, so you are comparing your real numbers, not an ad’s best case.
