Why Are Advertised Mortgage Rates Lower Than Your Quote?
Advertised mortgage rates are usually lower than your quote because they describe a different loan, a best case scenario built around the strongest credit score, the largest down payment, and sometimes paid discount points, rather than a loan priced against your actual file. It commonly comes from a shorter or adjustable-rate product, a different loan type, or an assumption that the borrower has a stronger credit and down payment profile than yours. Once you line up the same term, product, and borrower profile, the two numbers usually get much closer.
Last updated July 22, 2026What makes an advertised rate different from a personal quote?
Advertised rates are typically built around a best-case scenario: the strongest credit score, the largest down payment, and sometimes paid discount points, all rolled into one number designed to be as low as legally possible. A real quote is priced off your actual file. If your credit score, loan-to-value ratio, or loan type doesn't match that best-case scenario, the rate you're offered will be higher, sometimes by a meaningful margin.
Under federal advertising rules (Regulation Z), a lender generally can't advertise a rate unless it will actually be available to some qualifying applicant. That means the low rate isn't necessarily fake. It's real for someone, just not necessarily for you, depending on your situation.
Does my credit score and down payment matter that much?
Yes. Mortgage pricing is built around risk, and credit score plus loan-to-value (how much you're borrowing relative to the home's value) are two of the biggest risk factors lenders use to set your rate. A lower score or a smaller down payment typically means a higher rate, sometimes by a full percentage point or more depending on how far you are from the top pricing tier. Paying discount points, an upfront fee at closing, roughly 1% of the loan amount per point, can also buy the rate down, and an advertised rate may already assume points were paid that you haven't budgeted for.
Why do different loan types and terms have different rates?
An advertised rate is often tied to a specific product and term, and if yours is different, the comparison isn't apples to apples.
It depends on your situation:
- If the ad rate is a short-term or adjustable product: it's typically fixed only for an introductory period (commonly 3, 5, 7, or 10 years) before it adjusts. A true 30-year fixed rate for the same borrower generally runs higher.
- If the ad rate is for a shorter term, like 10 or 15 years, but you want a 30-year loan: shorter-term rates are typically lower than 30-year rates, so the real 30-year quote will usually be higher.
- If you're financing an investment property, second home, or a second lien/home-equity loan instead of a primary-residence purchase: these carry higher rates due to added risk-based pricing; second-lien products commonly run well above first-lien rates (roughly 7% to 12% as of 2026-07, depending on credit and loan-to-value, versus roughly 6% to 7% for a first-lien loan).
- If your credit and equity are genuinely strong: your real quote may land close to or match a competitive advertised rate, though this is the exception rather than the rule.
| Adjustable/teaser rate | Fixed for an initial period only (often 3, 5, 7, or 10 years), then adjusts |
|---|---|
| Discount points | Roughly 1% of loan amount per point, paid to lower the rate |
| Credit score / LTV | Major drivers of your actual rate versus the advertised best-case rate |
| Investment property / second home | Priced higher than a primary-residence purchase loan |
| Second lien / home equity loan | Commonly runs well above first-lien rates (roughly 7% to 12% as of 2026-07 vs roughly 6% to 7% first-lien) |
| 15-year vs. 30-year term | 15-year rates are typically lower than 30-year rates for the same borrower |
| Advertising rule | Under Regulation Z, an advertised rate generally must be actually available to some qualifying applicant |
