Mortgage rates went up because the Federal Reserve raised its benchmark interest rate by 25 basis points on September 16, 2026, moving its target range to 3.75% to 4%. That move pushed the 10-year Treasury yield up near 5%, and mortgage rates track the 10-year Treasury closely, according to Norada Real Estate's September 20 mortgage rate update. Add in ongoing concerns about federal debt and sticky inflation in energy and everyday goods, and lenders raised rates to match.

This wasn't a one-day blip. It was a direct response to a Fed decision, and rates held higher for the rest of the week.

As of September 17, 2026, Freddie Mac's Primary Mortgage Market Survey put the national average 30-year fixed rate at 6.95%, up from 6.76% the week before. That's a 19 basis point jump in a single week. Daily rate trackers move faster than Freddie Mac's weekly survey, and Norada Real Estate reported the 30-year fixed rate touching 7.04% by September 20, 2026, with refinance rates running even higher at 7.46% by September 22, 2026.

Whichever number you're looking at, the direction is the same. Rates in Westlake Village, California and everywhere else moved up fast this month.

We ran the numbers on a typical Westlake Village home to see what this means in real dollars. Zillow's Home Value Index puts the typical home value in Westlake Village, California at $1,570,507 as of August 31, 2026. On a 30-year loan for that home with 20% down, moving from 6.76% to 6.95% adds about $159 a month, or roughly $1,910 a year.

That's real money, but it's a lot less scary than the headlines make it sound. It's the kind of gap a stronger offer, a rate buydown, or a seller credit can help close.

Not necessarily. Homes in Westlake Village, California are going to pending in about 29 days, according to Zillow's August 2026 data, which tells you buyers are still moving on the good ones despite the rate jump. Home values here are also still up 4.1% year over year. If you wait a year hoping rates fall a point, you may end up paying more for the home itself and canceling out any savings on the loan.

Here's what to do instead of waiting:

• Get pre-approved now so you know your real number, not a guess.
• Ask your lender about rate buydowns or seller-paid credits.
• Compare a fixed rate against an adjustable-rate option for your timeline.
• Watch Freddie Mac's weekly rate update instead of daily headlines, since it's the number lenders actually use to price loans.

A little, but not a lot. Higher rates can shrink your buyer pool somewhat, since some buyers get priced out of their target budget. But Westlake Village, California isn't seeing prices drop. Zillow shows home values up 4.1% year over year, and Redfin's three-month median sale price of $1.8 million shows the top of the market, including lakefront and country club properties, is still active too.

If you're planning to sell, price it based on what's actually closing right now, not what the rate headlines make you assume.

It depends entirely on the rate on your current loan. If you locked in a rate below 6%, refinancing right now doesn't make sense with 30-year refinance rates sitting at 7.46% as of September 22, 2026. If you're carrying an adjustable-rate mortgage or a rate above 7.5%, it's worth running the numbers with a lender who knows the Westlake Village, California market.

A five-minute conversation can tell you if refinancing saves you money or costs you more.
