mortgage servicing delinquency rate measures the share of a mortgage servicing portfolio that is past due under the servicer's stated delinquency threshold.

Rocket Companies example

Rocket Companies reported a 1.50% 60-plus-day delinquency rate for its total serviced portfolio at year-end 2025.

Operational and credit context

Servicing delinquency affects borrower outreach, collections, loss-mitigation workload, advances, servicing cost, and MSR valuation assumptions. The metric describes the servicing population even when the servicer does not own the mortgage credit risk.

Do not confuse it with mortgage-insurance delinquency

The encyclopedia's private mortgage-insurance delinquency measures apply to insured-loan portfolios and insurance risk. A servicing delinquency rate uses the servicer's loan population and stated past-due threshold, so the two concepts are not interchangeable.

Where this concept fits

Servicing scale, MSR value, and portfolio durabilityCurrent relationship
Total serviced UPB and loan count measure platform scale; owned-MSR UPB and subserviced UPB separate economic ownership from servicing workload; average loan amount links balance and account scale; MSR fair value and its multiple frame valuation; and delinquency plus client retention show portfolio servicing burden and relationship durability.

Rate locks, closings, and gain-on-sale economics
Net rate lock volume is the fallout-adjusted locked pipeline, closed-loan volume is funded production, gain-on-sale margin connects loan-sale economics to the lock denominator, and servicing-retained mix determines how much production also creates continuing servicing exposure.
Closed Loan Origination Volume Gain-on-Sale Margin Net Rate Lock Volume Servicing-Retained Production Mix
Channel mix and mortgage-market capture
Direct-to-consumer and Partner Network production split funded originations by acquisition channel, while purchase and refinance market shares show competitive capture within two mortgage markets that can have very different rate and housing-cycle sensitivity.
