Investors are asking more questions than they used to about debt-service-coverage ratio (DSCR) loans, a surging segment of the mortgage market that operates outside government-backed parameters. This shift in sentiment marks a pivotal moment for the non-qualified mortgage (non-QM) sector, which has seen explosive growth over the last three years despite a backdrop of rising interest rates and tightening credit conditions. While the appetite for these products remains high, the nature of the conversation between lenders and capital market investors is becoming increasingly granular, focused on the underlying mechanics of risk assessment and the validity of property valuations.
“We’re having to do more explaining about how we think about the underwrite, how we arrived at the value, or just changes to our policies,” Charles Goodwin, vice president and head of bridge and DSCR lending at Kiavi, said in a recent interview. Goodwin noted that the environment has become more collaborative, with investors seeking a deeper understanding of the "why" behind the numbers. Crucially, however, he emphasized that these questions have not translated into a decrease in demand or a significant increase in the premiums required by the secondary market.
The Catalyst for Scrutiny: The Baltimore Fraud Case
The heightened level of due diligence currently observed in the DSCR space is not a random development. It follows a significant industry shock that came to light in mid-2025. Approximately one year ago, a suspected $100 million real estate fraud scheme was uncovered in Baltimore, Maryland. The scheme involved a group that reportedly purchased hundreds of residential properties—predominantly in majority-Black neighborhoods—at heavily inflated prices.
These transactions were financed by hundreds of millions of dollars in DSCR loans provided by dozens of private lenders. Because DSCR loans focus on the property’s income potential rather than the borrower’s personal financial history, the fraudsters were able to exploit the system. By the time the scheme was dismantled, more than half of the loans involved had defaulted, leaving lenders and securitization investors with substantial losses and a "bruise" on the reputation of the DSCR product.
While the Baltimore case served as a wake-up call, it failed to derail the national growth trajectory of the DSCR market. Instead, it served as a catalyst for technological innovation and more robust verification processes. Industry experts argue that the case was an outlier—a result of bad actors exploiting a specific niche—rather than a sign of systemic failure in the DSCR model itself.
Defining the DSCR Advantage in a High-Rate Environment
To understand why DSCR loans remain popular despite the Baltimore incident, one must look at their fundamental structure. Tailor-made for real estate investors, these loans bypass the traditional requirements of the mortgage industry. They do not require W-2 forms, pay stubs, or personal income tax returns. Instead, the primary metric for qualification is the Debt-Service-Coverage Ratio.
This ratio is calculated by dividing the property’s projected or actual monthly rental income by its monthly debt obligations (principal, interest, taxes, insurance, and association dues). If the property generates enough cash flow to cover the debt, the loan is considered viable. This methodology pushes DSCR loans outside the boundaries of government-sponsored enterprises (GSEs) like Fannie Mae and Freddie Mac, which typically require strict adherence to Ability-to-Repay (ATR) rules based on personal income.
For small, local real estate investors, this "box" is far easier to fit into than the rigid requirements of regional banks. Jacob Washburn, branch manager and senior mortgage adviser at Cornerstone Home Lending, noted that the majority of users are not large institutional "Wall Street" firms, but rather local individuals looking to build rental portfolios. For these borrowers, the DSCR loan represents a streamlined path to capital that values the asset over the individual’s employment history.
Statistical Growth: From Niche Product to Market Mainstay
Isolating data for DSCR loans can be challenging, as many data sources combine them with broader investor loan categories. However, the available metrics from firms like Optimal Blue and Bank of America paint a picture of a market in the midst of a historic expansion.
Between January 2022 and mid-2025—the period leading up to the revelation of the Baltimore fraud—lock volume for DSCR and investor loans jumped by roughly 40%. Even more striking is the growth that followed the scandal. By August 2026, lock volume growth had reached 130% compared to early 2022 levels.
The market share of these loans within the non-QM space has also shifted dramatically:
- August 2022: Investor and DSCR loans accounted for 22% of non-QM production.
- August 2025: The share rose to 28%.
- August 2026: The share reached 35%.
Bank of America analysts have projected that total non-QM originations will hit $175 billion in 2026. A June report from the bank noted that DSCR and investor loans are the primary drivers of this growth, now representing approximately 50% of all collateral within the non-QM sector. In a historic shift, non-QM investor and DSCR originations actually eclipsed agency and private-label investor issuance in 2025, signaling a permanent change in how rental properties are financed in the United States.
Market Drivers: Affordability and Product Diversification
Lending executives point to several macroeconomic factors fueling this expansion. The most prominent is the ongoing crisis of homebuyer affordability. As high interest rates and elevated home prices keep many Americans out of the purchase market, the demand for rental housing has surged. This creates a fertile environment for investors to acquire properties, knowing that the rental cash flow—and thus the DSCR—will remain strong.
Furthermore, the industry has seen aggressive product diversification by "mega lenders" such as Rocket Mortgage and United Wholesale Mortgage (UWM). As these giants navigate a high-rate environment that has suppressed traditional refinance and purchase volume, they have pivoted toward the DSCR and non-QM space to maintain origination levels.
This intense competition among lenders has kept pricing relatively tight. Ben Fertig, president at Constructive Loans, noted that DSCR rates currently hover between 7.125% and 7.25%. While higher than conventional rates, the spread has narrowed, making the loans more attractive to sophisticated investors. Fertig observed that originators who once relied solely on owner-occupied mortgages have "aggressively pivoted" to DSCR to survive the current market conditions.
Quantifying Fraud Risk and the Industry Response
The same features that make DSCR loans attractive—limited income verification and the ability to use LLCs—also make them a target for fraudulent activity. Data from Cotality, a firm that tracks mortgage fraud risk, highlights the disparity between traditional loans and investment-focused products.
At the end of the second quarter of 2026, Cotality found that one in 119 mortgage applications across all types showed signs of elevated fraud risk. However, for investment properties, that ratio plummeted to 1 in 44. For properties with two to four units, the risk was even higher, at one in 27 applications.
Matt Seguin, senior principal of mortgage fraud solutions at Cotality, noted that these segments have historically been three times more risky than owner-occupied loans. “The portion of volume in those two segments has gone from about 7% of the total volume in 2024 to about 12% in 2026,” Seguin explained. He also highlighted a 2.6% year-over-year increase in "undisclosed real estate debt" risk, a category where investors fail to mention other properties they own or debts they have incurred, which can artificially inflate their perceived creditworthiness.
In response, the industry is deploying advanced technology to create a "digital moat" around the underwriting process. Lenders are now utilizing:
- AI-Driven Algorithms: To detect patterns of "reverse occupancy" fraud, where an investor claims a property is a rental but intends to live in it to secure better terms.
- LLC Cross-Checks: Deep-dive database sweeps to uncover the true owners behind shell companies.
- Digital Photo Analysis: Using metadata and AI to ensure that property appraisals are current and haven’t been manipulated or reused from other listings.
- Automated Valuation Models (AVMs): To provide a secondary check on human appraisals, preventing the type of price inflation seen in the Baltimore case.
Fragmented Standards: The Moody’s Analysis
While technology is improving, the human element of underwriting remains inconsistent. A report published in late August 2026 by Moody’s Ratings revealed a highly fragmented market where underwriting quality varies significantly between originators.
Moody’s reviewed the practices of approximately 30 DSCR lenders and aggregators. The findings suggested that many lenders have embraced "weaker" standards to win business in a competitive market:
- 30% of programs allow borrowers to use the higher of appraised value or actual rent without a cap when calculating the DSCR.
- 40% permit DSCR floors between 0.75 and 0.99, meaning the property doesn’t even need to "break even" to qualify for the loan.
- 73% allow cash-out proceeds from the loan itself to satisfy the borrower’s reserve requirements.
- 50% of programs do not mandate personal guarantees from the majority owners of the LLC.
Ramon Bullard, vice president of U.S. residential mortgage-backed securities (RMBS) ratings at Moody’s, noted that while some originators have tightened their belts post-Baltimore, others continue to prioritize volume over stringent standards.
The "Skin in the Game" Factor
Despite the concerns over underwriting "floors," the actual performance of DSCR loans has remained remarkably resilient. Karandeep Bains, head of U.S. RMBS at Moody’s Investors Service, pointed to the high levels of equity in these deals as a primary reason for their stability.
The combined loan-to-value (CLTV) ratios for many DSCR pools are in the high 60s to low 70s. This means the average borrower is putting down 30% of the property’s value as a down payment. “These are borrowers that have significant skin in the game and have sufficient resources to make a substantial equity investment,” Bains said. Furthermore, 93% of the programs reviewed by Moody’s do require a personal guarantee for loans made to LLCs, which provides lenders with legal leverage to compel repayment and avoid the foreclosure process.
The Bank of America report supports this optimistic view of performance. Cumulative losses across the broader non-QM sector sit at just 3.6 basis points on roughly $281 billion in securitized originations since 2018. Out of 580,000 loans, only about 1,000 have incurred losses exceeding $10,000. While delinquencies of 30 days or more peaked in mid-2025, they have remained below the 6% threshold, a figure that is manageable for most institutional investors.
Future Outlook: Vigilance as the New Standard
As the DSCR market continues to mature, the consensus among industry leaders is that the Baltimore fraud case was a lesson in the necessity of transparency rather than a reason to retreat from the product. The evolution of the rental market—moving from a niche investment to a core component of the American housing economy—suggests that DSCR loans will remain a permanent fixture of the mortgage landscape.
The future of the sector will likely be defined by a "flight to quality," where lenders who can demonstrate superior data verification and robust underwriting standards will command the best pricing in the secondary market. For originators, the message is clear: innovation in loan programs must be matched by innovation in fraud detection.
“The overwhelming majority of DSCR borrowers are responsible real estate investors providing housing for their communities,” Jacob Washburn of Cornerstone Home Lending concluded. “I wouldn’t want a fraud case to define the product. The lesson is that transparency and verification just have to keep pace with innovation.”
