LIHTC Expansion Positions Affordable Housing for Accelerated Growth in 2026

Key Points:

• Federal legislation permanently extends the 12.5% increase to each state’s 9% LIHTC allocation, materially boosting affordable housing capacity nationwide.
• Expanded LIHTC equity can now cover up to 70% of eligible development costs, improving project feasibility amid moderating interest rates.
• Total LIHTC allocations are projected to rise by 50% over the next two years, supporting an estimated 1.22 million new affordable rental homes by 2035.
• Declining market-based borrowing costs and increased FHFA investment could further accelerate affordable housing starts in 2026.

What the Data Shows

Recent federal action to permanently extend the 12.5% increase in 9% Low-Income Housing Tax Credit (LIHTC) allocations, often referred to as the LIHTC expansion, marks one of the most significant policy tailwinds for affordable housing in over a decade. According to Arbor’s analysis, the enhanced credit structure allows LIHTC equity to fund up to 70% of eligible development costs, narrowing capital gaps that have constrained new construction in recent years. Over the next two years alone, total LIHTC allocations are expected to increase by roughly 50%, materially expanding the development pipeline and improving underwriting certainty for sponsors and lenders alike. Arbor research estimates that this expansion could ultimately support the creation of approximately 1.22 million additional affordable rental homes by 2035, a meaningful step toward addressing long-standing supply shortages.

How Major Markets Are Responding

Affordable housing creation over the next 10 years is projected to vary widely by state and region. Large-population states, such as California and Texas, are positioned to see the most units created, while smaller markets may experience outsized impacts relative to their size as additional credits unlock projects that were previously infeasible. 

Arbor’s state-by-state projections highlight how expanded LIHTC allocations could translate into thousands of incremental units annually, particularly in markets where demand for rent-restricted housing continues to outpace supply. As borrowing costs trend downward and FHFA-backed investment expands, developers in both primary and secondary markets may find 2026 to be a pivotal year for advancing stalled or delayed affordable housing projects.

The Takeaway

The permanent LIHTC increase, combined with improving capital market conditions, signals a structural shift for the affordable housing sector. With more predictable equity, enhanced coverage of development costs, and growing public-sector support, 2026 could mark the beginning of a sustained expansion in affordable rental supply. For investors, lenders, and developers, the current environment underscores the importance of aligning capital strategies with evolving federal policy and state-level allocation dynamics.
