Freddie Mac's single-family serious delinquency rate edged up to 0.61% in September 2026 from 0.60% in August, while its multifamily rate fell to 0.58% from 0.64%, according to the company's Monthly Volume Summary for September, posted Oct. 26. The report is a snapshot of Freddie Mac's portfolios, securities and funding, not a measure of mortgage rates or application demand.

Purchase loans dominate
Of Freddie Mac's single-family loan purchases in September, $5.4 billion, or 18%, were refinances. The remaining 82% were purchase-money loans. That split describes what Freddie Mac bought in the month, which lags the original lending decisions; it is not the same as the refinance share of new applications in weekly lender surveys.
Portfolio growth slowed but stayed positive
Freddie Mac's total mortgage portfolio, which combines loans it holds and loans it guarantees in securities, grew at an annualized 1.4% in September to about $3.71 trillion. Purchases and issuances of $36.3 billion exceeded liquidations of $32.1 billion. The smaller mortgage-related investments portfolio, the part Freddie Mac holds on its own balance sheet, ended the month at $135.4 billion. Freddie Mac's indebtedness counted toward its Purchase Agreement limit fell by roughly $5.9 billion in the month, to $171.6 billion.
Delinquency in context
A 0.61% single-family delinquency rate means that about six in every 1,000 loans in Freddie Mac's single-family book were seriously delinquent. The multifamily rate improved from a higher August reading.
What it means for borrowers
Nothing in this report changes what a borrower pays today. It does show that Freddie Mac's book remains dominated by purchase loans and that credit performance on its single-family loans is still low by historical standards. Borrowers who are struggling with payments can contact their servicer early to ask about options available on Freddie Mac-owned loans.
