The Qualified Mortgage Rule: Impact on Lending, Borrowers & the Market

Mortgage regulation walks a fine line — protecting borrowers while keeping credit accessible. One of the most significant frameworks in modern lending is the Qualified Mortgage (QM) Rule, which continues to shape how lenders evaluate risk and how borrowers access financing.

In this article, StratoBridge Lending explores how the QM rule affects today’s mortgage market, why Non-QM lending is expanding, and what the data reveals about this ongoing shift.

What Is the Qualified Mortgage Rule?

The Qualified Mortgage (QM) Rule, built from the Ability-to-Repay (ATR) requirement, ensures that lenders make responsible lending decisions. A “Qualified Mortgage” meets specific underwriting criteria designed to verify a borrower’s ability to repay the loan.

Key Features of QM Loans

• Verified income, employment, and assets

• DTI ratio typically below 43%

• No risky features like interest-only or negative amortization loans

• Caps on fees (commonly 3% of loan amount)

• “Safe Harbor” protection for compliant lenders

This framework creates a safer lending environment but can limit flexibility for nontraditional borrowers — particularly self-employed individuals and property investors.

The Data: How QM and Non-QM Lending Have Evolved

Since the QM rule’s implementation, the lending landscape has evolved significantly. As the chart below shows, Non-QM loans — once niche — are now an important part of the market.

 (Non-QM loans have grown from roughly 2% of total mortgage originations in 2018 to around 8% by 2025.)

This expansion reflects the increasing demand for more flexible financing — particularly among real estate investors, self-employed professionals, and borrowers with nontraditional income streams.

Understanding APR–APOR Spread Differences

Another key distinction between QM and Non-QM loans lies in pricing — specifically the APR–APOR spread, or how much higher the loan’s annual percentage rate (APR) is compared to the Average Prime Offer Rate (APOR) benchmark.

(Non-QM loans carry an APR–APOR spread roughly 1.5–2 percentage points higher than QM loans due to greater flexibility and risk tolerance.)

These spreads illustrate why Non-QM products often have slightly higher rates — lenders price in additional risk associated with nontraditional income verification and property-based underwriting.

Market Impacts of the QM Rule

1. Safer but Stricter Lending

The QM rule has greatly reduced the presence of risky loan features, contributing to market stability. However, it also made qualifying more challenging for borrowers with variable or complex income.

2. Rise of Alternative Documentation

Non-QM lenders now use bank statements, rental income (DSCR), or asset-based underwriting instead of tax returns. This opens access to financing for strong borrowers who don’t fit standard documentation molds.

3. Growing Investor Activity

Real estate investors increasingly rely on Non-QM financing. In 2024 alone, investor-focused Non-QM products accounted for more than 35% of Non-QM loan volume — driven by demand for DSCR loans and short-term rental financing.

What This Means for Borrowers

Homebuyers

If you have traditional income and stable employment, a QM loan is often your best path — it provides lower rates, predictable payments, and federal consumer protections.

Self-Employed Borrowers & Investors

If you earn income through business ownership, rental properties, or investments, Non-QM loans may offer better flexibility. While rates are typically 1–2% higher, these loans can leverage your real-world financial strength rather than rigid paperwork requirements.
