Refinancing Window Shrinks to 2% of Agency Mortgages as Rates Rise, Urban Institute Finds

Homeowners have far fewer chances to cut their mortgage rate than they did earlier this year, according to a new Urban Institute report that shows how rising borrowing costs have narrowed the refinancing market.

Only 2.0% of outstanding agency mortgages met the research group’s rate-based refinancing measure in September, down from 11.5% in February. The finding appears in Urban’s October housing-finance chartbook, released Friday.

The measure counts loans with an existing interest rate at least half a percentage point above the mortgage rate reported in Freddie Mac’s Primary Mortgage Market Survey. It identifies a potential rate advantage, not a guarantee that a borrower will qualify or save money after refinancing costs.

Higher rates shrink the opening

The change reflects a widening gap between today’s borrowing costs and the lower rates many homeowners already have. Urban reported that 79.8% of outstanding agency borrowers had mortgage rates of 6% or less in September.

For those households, replacing an existing loan with a new mortgage at a higher rate offers no rate reduction. That leaves a smaller pool of borrowers who could lower their rate by refinancing, even when they have substantial equity in their homes.

The chartbook’s separate mortgage-rate series reached 7.24% as of October 29, compared with a 2026 low of 5.98% in February. That later rate reading is distinct from the September loan data used to calculate the 2.0% refinancing share.

What the numbers mean for borrowers

The finding concerns outstanding agency mortgages, not every home loan in the country. It also does not mean that the remaining 98% of borrowers are barred from refinancing. A homeowner might refinance for reasons other than lowering the interest rate, including taking cash out of home equity.

Urban said cash-out loans have become a larger share of refinancings, even as overall refinancing volume remains low. A growing share within a small market is different from a broad rebound in mortgage activity.

For lenders, the smaller pool of loans with a potential rate advantage limits one source of refinancing business. For homeowners, the main distinction is between having equity and having an opportunity to replace a mortgage at a lower rate. The two do not necessarily move together.

The report puts aggregate household housing equity at $35.8 trillion in the second quarter. That figure covers a different period and measure from the September refinancing analysis, but it illustrates why a large stock of housing wealth can coexist with limited opportunities to reduce borrowing costs.

The 2.0% figure is a market snapshot, not a borrower-specific recommendation. It measures a rate gap, rather than a full decision that accounts for a household’s loan terms, refinancing costs and eligibility.
