Today’s Mortgage Rates (Purchase Loans)
Here are the national average rates for buying a home right now. Remember, these are rounded to the nearest hundredth of a percent—your actual rate depends on your credit, down payment, and lender.

What’s a “basis point”?
One basis point = 0.01%. So 8 basis points = 0.08%. Tiny changes, but they add up over 30 years!
Today’s Refinance Rates
Refinancing replaces your current mortgage with a new one. Rates are usually a tad higher than purchase rates.

Mortgage Types Explained (ELI5 Style)
30‑Year vs. 15‑Year Fixed: The Classic Trade‑Off
| 30‑Year Fixed | 15‑Year Fixed | |
|---|---|---|
| Rate (example) | 6.19% | 5.65% |
| Monthly Payment | ~$2,447 | ~$3,300 |
| Total Interest Paid | $481,021 | $194,047 |
| Best For… | Lower monthly budget | Saving $$$ long‑term |
Pro Tip: Can’t swing the 15‑year payment? Get the 30‑year and pay extra when you can. You’ll still slash years and interest off the loan.
Fixed‑Rate vs. Adjustable‑Rate (ARM): Locked In vs. Flexible
| Feature | Fixed‑Rate Mortgage | Adjustable‑Rate Mortgage (ARM) |
|---|---|---|
| Rate Changes? | Never (unless you refinance) | Yes—after an initial “teaser” period |
| Example | 30‑Year Fixed at 6.53% | 7/1 ARM: Fixed 7 years, then adjusts every year |
| Risk Level | Low—payment stays predictable | Higher—payment could jump after year 7 |
| When ARM Wins | — | If you’ll sell/refinance before the fixed period ends |
Heads Up: Lately, ARM starting rates have been higher than fixed rates—so the traditional “ARM discount” isn’t always there.
Key Takeaways (Cheat Sheet)
TL;DR
- 30‑year fixed held steady at 6.53% (good news for most buyers).
- 15‑year and ARMs ticked up—shorter loans got pricier.
- Refi rates run ~0.1–0.2% higher than purchase rates.
- VA loans stay competitive (often below conventional rates).
- Always compare 3+ lenders—averages ≠ your quote.
Summary
Today’s mortgage landscape is a mixed bag: the benchmark 30‑year fixed barely moved (6.53%), while shorter terms and adjustable loans crept higher. If you’re buying, the 30‑year fixed remains the “safe harbor” for predictable payments. If you can afford higher monthly checks, a 15‑year fixed saves nearly $300k in interest on a $400k loan. ARMs? Only consider them if you’re certain you’ll move or refinance before the rate adjusts—and even then, check if a fixed rate beats the ARM’s starting price.
Next Steps:
- Run your numbers in the calculator above.
- Get pre‑approved with 2–3 lenders (credit unions, big banks, online).
- Lock your rate once you’re under contract—don’t gamble on future drops.

6.53% (national average, down 0.01% from yesterday).
2. Will mortgage rates go down in 2026?

Translation: No big crash expected—plan for “higher for longer.”
3. How low could rates go by 2027?
Most models say not much lower:

- Fannie Mae: ~6.3%.
Bottom line: Don’t bet on 3% rates returning soon.
4. Are refinance rates always higher than purchase rates?

5. Should I choose a 15‑year or 30‑year mortgage?
- Pick 15‑year if: You want to own faster, hate paying interest, and cash flow allows it.
- Pick 30‑year if: You need breathing room monthly, want to invest the difference, or prefer flexibility (you can always pay extra!).
