Freddie Mac’s survey put the average 30-year fixed mortgage rate at 7.28 percent in the week of Oct. 1, the highest reading since November 2023, according to Fox Business. A year earlier it was 6.34 percent.

At Westport prices, a single percentage point is real money. We ran the standard amortization formula for three purchase prices, assuming 20 percent down and a 30-year fixed loan.

Purchase priceLoan at 80 percentMonthly at 6.34%Monthly at 7.28%Difference per month
$1,500,000$1,200,000$7,459$8,211$752
$2,425,000$1,940,000$12,059$13,274$1,215
$3,500,000$2,800,000$17,404$19,158$1,754

The middle row uses the town’s single-family median for January through August 2026, $2,425,000, according to SmartMLS data compiled by the Riverside Realty Group. At that price the higher rate costs about $14,580 more a year. Payments shown are principal and interest only.

A note on jumbo loans

Freddie Mac’s survey tracks conventional loans. At Westport prices, a buyer financing 80 percent of a purchase will almost always need a jumbo loan, which lenders price on their own terms. The survey is still a good guide to the direction of rates, but ask lenders for jumbo quotes before you use any of these numbers to set a budget.

Why it may not cool prices much

Higher rates usually slow a market, and September’s early numbers were soft. But Westport’s inventory is unusually thin, with 59 single-family houses listed in August, down 35.9 percent from a year earlier, and scarcity tends to support prices. Our market report follows both trends, and our guide to ownership costs covers taxes, insurance and the rest of the monthly bill.
