For the past year, much of the housing conversation has revolved around one question: When will rates fall?
Market participants are watching signals from the Federal Reserve and the anticipated leadership transition from Chair Jerome Powell. The assumption is that once rates decline meaningfully, affordability will improve, and housing activity will rebound.
But lower rates alone will not fix today’s affordability challenges. In fact, in a supply-constrained market, cheaper financing can just as easily reignite price growth — making affordability worse rather than better.
As discussed in ABL’s recent “Fed Reset” webinar, the market isn’t simply waiting for rate relief. It’s adjusting to a new normal shaped by long-term supply shortages, higher operating costs, and changing investor behavior.
The lenders and investors who succeed next will be the ones who adapt to these structural realities — not the ones waiting for 2021 rate conditions to return.
Affordability Is A Supply Problem, Not Just A Rate Problem
It’s easy to blame affordability on interest rates. Higher rates increase monthly payments, and that matters.
But the bigger issue is supply.
The U.S. has been underbuilding housing for more than a decade. Even with increased construction activity in recent years, inventory remains tight. At the same time, more than half (51.5%) of outstanding mortgages still have rates at or below 4%, and nearly 69% carry rates of 5% or lower according to Realtor.com, leaving them with little incentive to sell. That limits resale inventory and keeps supply constrained.
Even if rates fall, there simply aren’t enough homes available in many markets. When demand is stimulated without a meaningful increase in supply, prices tend to adjust upward.
Housing starts ended on an up note at the end of 2024, increasing to 15.8% in December. However, construction costs also remain elevated. Over the past five years, labor costs have risen roughly 28%, and materials costs have increased about 46%. Builders can’t easily lower prices when their own costs are this high. Add in rising insurance premiums and higher property taxes in many states, and the affordability squeeze becomes even more persistent.
Lower rates may help at the margin. But without more supply, cheaper financing can just as easily push prices higher again. History shows that when borrowing costs fall in a tight inventory environment, buyers gain purchasing power and sellers often respond by raising asking prices. The result can be higher nominal home values rather than true affordability relief.
That’s why affordability today is not just a temporary rate issue. It’s a long-term imbalance between supply, costs, and demand.
Policy Shifts May Change The Competitive Landscape
Recent policy discussions have also focused on institutional investors in the single-family rental space. Proposed limitations on federal financing could alter how capital flows into housing and potentially narrow certain funding channels traditionally used by major institutional buyers.
Institutional ownership accounts for only a small percentage of single-family rentals — estimated around 3% nationally — but the competitive impact in specific markets can be meaningful. If access to low-cost federally backed financing becomes more limited for large operators, smaller and mid-sized investors may encounter less competition in certain acquisition segments.
For independent investors and regional operators, this shift could create opportunity. With fewer large institutional buyers bidding aggressively in entry-level and workforce housing, well-capitalized smaller investors may find more favorable pricing and improved deal flow. Lenders that specialize in serving this segment — particularly those providing flexible, asset-based capital solutions — are positioned to support that growth.
At the same time, proposals for renewed mortgage-backed securities purchases, potentially up to $200 billion, are designed to stimulate affordability through liquidity support. While that may compress rates temporarily, it does not address the underlying supply shortage. Even though borrowing costs could be lowered by injecting liquidity into a constrained market, it can also increase demand pressure and contribute to renewed price acceleration.
Policy changes can create opportunity windows. But they don’t replace disciplined underwriting or strong asset selection.
Why Cash-Flow Lending Is Gaining Ground
As the market adjusts, investor behavior is changing.
The focus has shifted from appreciation to cash flow.
Debt Service Coverage Ratio (DSCR) lending has expanded because it reflects how professional investors evaluate real estate. Instead of qualifying borrowers based primarily on personal income and DTI ratios, DSCR underwriting looks at whether the property’s rental income covers its debt obligations.
That shift makes sense in today’s environment.
Investors are increasingly:
- Using realistic rent comps
- Stress-testing deals at current rates
- Modeling vacancies and expenses conservatively
- Avoiding properties that only work under aggressive appreciation assumptions
Deals need to make sense on day one. Because if prices move higher in response to rate cuts, only properties with strong underlying cash flow will remain resilient.
ABL’s internal data shows that investor loan rates have compressed by roughly 100 basis points year over year, with the potential for an additional 50 to 100 basis points of downward movement into 2026. That helps improve deal math. But even with some rate compression, discipline remains critical. If lower rates trigger another round of price increases, investors who underwrite based solely on cheaper debt rather than durable cash flow may find margins quickly compressed.
DSCR lending isn’t an easier version of underwriting. It simply aligns financing with how rental properties actually perform.
What This Means For Lenders
For lenders focused on non-agency and investor loans, affordability pressures mean strategy matters more than ever.
First, diversification is important. When owner-occupied volume slows because of affordability constraints, investor lending can provide more consistent activity — especially in markets supported by population growth and rental demand.
Second, leverage discipline is key. High loan-to-value ratios combined with thin coverage margins create unnecessary risk. Lenders need appropriate DSCR thresholds, reserves, and realistic rent assumptions to protect portfolios if conditions soften.
Third, rental analysis must be grounded in real market data that is more granular vs. relying on more general data for large localities. Overly optimistic rent projections can undermine performance. Strong programs rely on documented comps and conservative modeling that analyze precise data that reflects trends by zip codes — or even neighborhood blocks.
Lenders also need strong relationships with warehouse providers and secondary market buyers. Capital markets execution depends on consistency and credit performance. Volume without discipline eventually creates problems.
Adding a DSCR product is not enough. Successful lenders build internal expertise, educate brokers and correspondents, and maintain consistent underwriting standards.
What This Means For Investors
For investors, the current market rewards patience and discipline.
Rapid appreciation is no longer the primary strategy. Cash flow stability is.
Investors are focusing on:
- Workforce housing with durable rental demand
- 1–4 unit properties and small-balance multifamily
- Maintaining liquidity and reserves
- Evaluating insurance and tax trends before acquisition
Because DSCR qualification centers on property income, investors can scale portfolios without repeatedly navigating complex personal income documentation. That flexibility supports more systematic growth.
Population migration into parts of the South and Southeast — and even certain parts of the Midwest — continues to support rental demand. But smart investors are not assuming unlimited rent growth. They are underwriting conservatively and planning for long-term sustainability.
Short-term rate compression may create buying opportunities. But disciplined investors focus on properties that perform even if rate-driven demand pushes prices higher again. Buying into a market where financing is cheaper but valuations are inflated requires even greater underwriting discipline.
A Market That Is Adjusting, Not Stalled
The housing market isn’t frozen. It’s adjusting.
Affordability pressures are likely to persist because they stem from supply shortages and cost inflation — not just interest rates. Monetary policy can influence liquidity, but it cannot quickly fix zoning restrictions, labor shortages, or construction costs.
In this environment, asset-based lending is becoming a core part of the mortgage ecosystem rather than a niche product.
For lenders, adapting now means building durable capability in investor underwriting and capital markets alignment.
For investors, it means focusing on cash-flow stability rather than speculative gains.
Strategy Over Speculation
Lower rates, when they arrive, may help. But they will not solve structural affordability challenges on their own. Without additional housing supply, cheaper money risks fueling higher home prices rather than restoring affordability.
The next phase of growth will belong to lenders and investors who accept that reality and adjust accordingly.
Disciplined underwriting. Realistic rent assumptions. Appropriate leverage. Strong capital relationships.
In a market defined by long-term constraints rather than short-term volatility, strategy — not speculation — will separate durable operators from the rest.
