Oregon Homebuyers Face Nearly $900 More a Month as Mortgage Rates Hit 6.66%

A recent survey indicates that the average 30-year fixed mortgage reached 6.66% last week, adding around $900 to Oregon homeowners’ monthly mortgage payments on a $500,000 home with 20% down.

In 2021, on a $500,000 home with 20% down, the principal and mortgage rates average interest would be about $1,686 at 3% in 2021. In July 2026, this increased to $2,570 at 6.66%, an increase of about $884 a month.

The rate is up from 6.58% one week earlier but is not a new high. Mortgage interest rates stood at 6.72% in July 2025.

The average interest rates are:

• 30-year Fixed-Rate Mortgage: 6.66%
• 15-year Fixed-Rate Mortgage: 6.04%

In the Oregon housing market, unaffordability is similar to the national averages. The median sale price in Oregon was $518,159 in May 2026, down 0.74% from a year earlier.

The increased payment (principal and interest)- with a 20% down payment- would be about $2,664 a month at 6.66%, compared with about $1,748 at 3%, a difference of $916 monthly or nearly $11,000 annually.

There were 20,045 homes for sale in Oregon, up 0.09% year over year. The number of newly listed homes was 5,033, down 3.5% year over year.

The average months of supply is 4 months, but the average is up 6.1% year over year, so the available data does not support saying the market has frozen.

The bigger problem is the mortgage lock-in problem- existing owners with rates near 3% may face roughly $900 more per month to buy a similarly priced home in the state now.
