One of the largest U.S. mortgage servicers (formerly Nationstar), which also originates and refinances loans for its large customer base.

Mr. Cooper by the numbers

Source: federal HMDA data (2025), FFIEC/CFPB. *Approval rate = loans originated ÷ (originated + denied). It reflects a lender's channel and borrower mix — wholesale, online and refi-heavy lenders run lower because many applications are rate shops that never close — not how hard it is to work with.

Mr. Cooper at a glance

Mr. Cooper is one of the largest mortgage companies in the United States, headquartered in Coppell, Texas.

It began as Nationstar Mortgage, a nonbank lender that grew rapidly after Fortress Investment Group took control in 2006 and took the company public in 2012. In August 2017, Nationstar rebranded as Mr. Cooper, positioning itself around a more consumer-facing identity.

Unlike a traditional bank, it does not take deposits; it funds and sells loans and, above all, services them.

The distinction between originating and servicing is central to understanding this company. Originating means underwriting and funding a brand-new mortgage.

Where Mr. Cooper's approval rate sits

Mr. Cooper's 2025 approval rate of 80.8% sits against the 76.6% national average. Read it as a signal of channel, not strictness — wholesale, online and refinance-heavy lenders run lower because so many applications are rate shops that never close.

Servicing means administering an existing loan after closing: collecting monthly payments, managing escrow for taxes and insurance, and handling payoffs, hardship, and default. Mr. Cooper is best known as a servicing giant, holding one of the largest portfolios in the country.

A great many of its customers never chose it at all; their loan was originated elsewhere and the servicing rights were later transferred to Mr. Cooper, so they simply began sending payments to a new company. That transfer dynamic shapes much of how borrowers experience the brand.

Mr. Cooper also runs a direct origination and refinance business. In 2025 it reported 52,217 originated loans against 12,404 denials, an approval rate of about 80.8%, totaling roughly $9.99 billion in volume at an average loan size near $191,387.

In a major industry development, Rocket Companies completed its all-stock acquisition of Mr. Cooper Group effective October 1, 2025, combining the nation's largest originator with its largest servicer; Mr. Cooper's operations are being folded under the Rocket brand.

Who Mr. Cooper is best for

Mr. Cooper is most relevant to two groups: existing homeowners whose loan servicing was transferred to it and who now manage payments through its app and website, and borrowers shopping a straightforward refinance or purchase who want a large, established nonbank lender.

Following the Rocket acquisition, prospective borrowers should confirm which brand and platform they are actually applying through.

The verdict

Mr. Cooper is a large, established nonbank best understood as a servicing powerhouse that also originates and refinances loans. Most borrowers encounter it because their mortgage was transferred to it, not because they picked it.

Its complaint volume largely reflects its size and servicing role. With Rocket's October 2025 acquisition now complete, anyone applying should verify current terms and branding, and compare offers against several lenders before deciding.

How to compare Mr. Cooper

Shopping a few lenders is the single most reliable way to save. Before you commit to Mr. Cooper:

1. Get three or more Loan Estimates in a two-week window — the bureaus treat it as one inquiry.
2. Compare the APR, not just the headline rate — it folds in the fees.
3. Weigh service and loan-type fit, not price alone.
4. Verify licensing on NMLS Consumer Access (Mr. Cooper's HMDA filer ID: 549300LBCBNR1OT00651).

Benchmark whatever you're quoted against today's average rates by loan type.
