Mortgage Rates Today, Tuesday, September 30: A Little Higher

Mortgage rates continued to rise today, albeit by a small step rather than a giant leap.

The average interest rate on a 30-year, fixed-rate mortgage rose to 6.43% APR, according to rates provided to NerdWallet by Zillow. This is four basis points higher than yesterday and 10 basis points higher than a week ago. (See our chart below for more specifics.) A basis point is one one-hundredth of a percentage point.

Yes, mortgage rates are higher even though the Fed just cut rates. Mortgage interest rates moved down ahead of the Federal Reserve meeting, hitting their lowest point the day before the rate cut announcement.

That didn’t last, though today’s mortgage rates are still lower than what we’ve seen through most of 2025. The month of September’s average rate — 6.42%, almost exactly where we are today — is the lowest monthly average so far this year.

Mortgage rates are constantly changing, since a major part of how rates are set depends on reactions to new inflation reports, job numbers, Fed meetings, global news… you name it. For example, even tiny changes in the bond market can shift mortgage pricing.

This week, the Nerds are looking ahead to the September jobs report, which the Bureau of Labor Statistics should release on Oct. 3. Right now that’s a “should” rather than a “will” because of the looming threat of a government shutdown on Oct. 1. The data informing the report will have already been collected by then, but if there’s a shutdown it won’t be released.

All of that said, if jobs numbers are weaker, that could push rates downward. A floundering labor market would bolster the Federal Reserve’s case for lowering the federal funds rate again at their next meeting. But if the data proves to be unexpectedly strong, we might see rates tick up as central bankers’ path forward would become more uncertain.

There is no universal “right” time to start shopping — what matters is whether you can comfortably afford a mortgage now at today’s rates.

If the answer is yes, don’t get too hung up on whether you could be missing out on lower rates later; you can refinance down the road. Focus on getting preapproved, comparing lender offers, and understanding what monthly payment works for your budget.

NerdWallet’s affordability calculator can help you estimate your potential monthly payment. If a new home isn’t in the cards right now, there are still things you can do to strengthen your buyer profile. Take this time to pay down existing debts and build your down payment savings. Not only will this free up more cash flow for a future mortgage payment, it can also get you a better interest rate when you’re ready to buy.

If you already have a quote you’re happy with, you should consider locking your mortgage rate, especially if your lender offers a float-down option. A float-down lets you take advantage of a better rate if the market drops during your lock period.

Rate locks protect you from increases while your loan is processed, and with the market forever bouncing around, that peace of mind can be worth it.

Refinancing might make sense if today’s rates are at least 0.5 to 0.75 of a percentage point lower than your current rate (and if you plan to stay in your home long enough to break even on closing costs).

With rates where they are right now, you could start considering a refi if your current rate is around 6.93% or higher.

Also consider your goals: Are you trying to lower your monthly payment, shorten your loan term or turn home equity into cash? For example, you might be more comfortable with paying a higher rate for a cash-out refinance than you would for a rate-and-term refinance, so long as the overall costs are lower than if you kept your original mortgage and added a HELOC or home equity loan.

If you’re looking for a lower rate, use NerdWallet’s refinance calculator to estimate savings and understand how long it would take to break even on the costs of refinancing.

The rate you see advertised is a sample rate — usually for a borrower with perfect credit, making a big down payment, and paying for mortgage points. That won’t match every buyer’s circumstances.

In addition to market factors outside of your control, your customized quote depends on your:

• Location and property type

Even two people with similar credit scores might get different rates, depending on their overall financial profiles.

Maybe — but even personalized rate quotes can change until you lock. That’s because lenders adjust pricing multiple times a day in response to market changes.
