A new report repositions residential transition lending as a measurable, market-driven force in U.S. housing production.

The Urban Institute’s newly released report “The Evolution of Residential Transition Lending: From Hard Money to Housing Supply?” reframes residential transition lending (RTL) from a fringe financing mechanism into a material contributor to U.S. housing production.

Supported by the Housing Finance Innovation Forum, the April 2026 report concludes that RTL has evolved into a meaningful source of capital for small-scale residential construction and rehabilitation. Its activity is concentrated in infill development and the production of “missing middle” housing, including duplexes, triplexes, and small multifamily properties—segments that both institutional capital and public subsidy programs structurally underserve.

Drawing on market data and industry interviews, the report estimates that more than $85 billion in RTL originations occurred in 2025, including over $25 billion dedicated to one-to-four-family ground-up construction and more than $35 billion to property rehabilitation.

The findings position RTL as a supplemental, market-driven mechanism helping to address gaps left by traditional bank lending and large-scale developers. This was further highlighted in the report’s contrasting of the banking sector’s $91 billion in outstanding single-family construction loans (as of EOY 2025) against RTL’s additional $30 billion.

Who’s Borrowing—and Why

Unlike conventional mortgage channels that facilitate purchases of existing housing stock, RTL finances its creation and improvement. The report emphasizes that these loans disproportionately support modest, scattered-site development in established communities, often resulting in affordable housing units.

The report also substantiates a distinction that industry participants have long observed. Drawing on borrower-level data from Forecasa, which the report characterizes as the most comprehensive and reliable source available for RTL borrower behavior, it segments the market between “casual” and more active investors. Casual borrowers—those completing three or fewer projects annually—generally lack access to bank construction financing due to underwriting constraints tied to experience, scale, and recourse.

More active borrowers, by contrast, often have the capacity to pursue lower-cost bank capital, yet continue to use RTL. The report attributes this preference to structural features of RTL products, including asset-based underwriting, higher leverage, expedited execution timelines, and greater flexibility in loan terms.

This indicates that private lending does not function solely as a fallback for capital-constrained borrowers. Instead, it operates as a deliberate financing choice across varying levels of borrower sophistication.

The report’s findings also reinforce several structural realities. RTL has matured significantly, transitioning from “hard money” into a more institutionalized market with diverse capital sources, standardized practices, and growing securitization activity.

Conversely, the sector retains a distinct local orientation. The report notes that 83 percent of private lenders work with fewer than 10 unique borrowers, and those borrowers typically complete only one or two projects every few years.

It attributes this persistent hyperlocal structure to both operational realities and borrower demand—qualities that explain why the market is likely to remain distinct from banking’s evolutionary path of consolidation and standardization.

Short loan durations allow lenders to remain balance-sheet driven, reducing dependence on secondary market execution and insulating them from the volatility observed during and after the pandemic. At the same time, borrower preferences reinforce this structure. Borrowers select RTL products for their flexibility, speed, and customization, characteristics that resist commoditization and diminish rate sensitivity relative to traditional lending channels.

This dynamic creates a structural tension with capital markets, which favor standardization and scale. Many RTL lenders resolve that tension by maintaining portfolio-based models that preserve underwriting discretion while managing risk exposure. The report further emphasizes that the construction-focused nature of RTL reinforces localized expertise, requiring lenders to develop granular knowledge of neighborhood conditions, construction costs and timelines, contractor reliability, and the feasibility of exit strategies tied to rental or sale outcomes.

This type of activity is more commonly associated with government-backed housing initiatives, despite being entirely market-driven.

Institutional Attention Signals Market Maturation

The involvement of the Urban Institute and the Housing Finance Innovation Forum carries broader implications for the private lending sector. Their engagement signals a shift in how policy researchers and institutional stakeholders perceive RTL.

The sector is now subject to rigorous, evidence-based analysis. That attention functions as validation. The report formally recognizes residential transition lending as a legitimate and measurable contributor to housing supply, supported by empirical data.

AAPL’s Role in Advancing Research and Industry Visibility

The American Association of Private Lenders played a direct role in shaping the report’s evidentiary base.

“This report reflects what happens when rigorous research is informed by active market practitioners,” said Linda Hyde, AAPL’s president. “The report cited several thought pieces and data published in our flagship publication, Private Lender, demonstrating our infrastructure not only supports industry participants but also enables external stakeholders, including researchers and policymakers, to engage.”

AAPL’s involvement, Hyde said, reflects its broader strategy to provide public platforms for knowledge exchange. Through its magazine, digital content, webinars, educational programming, and conferences, the association provides practitioners, researchers, and the public with access to real market intelligence.
