The Qualified Opportunity Zone (QOZ) program—established under the Tax Cuts and Jobs Act—has generated substantial interest among real estate developers and private lending clients since its inception. The program allows investors to defer, reduce, and in some cases eliminate capital gains taxes by channeling investment into designated opportunity zone properties. For developers and fund sponsors, the program’s benefits are compelling on paper, but realizing those benefits depends heavily on getting the capital stack right from the outset.
This article examines the structural considerations for financing Qualified Opportunity Zone projects, with particular focus on ground-up construction, HUD-insured financing, and the intersection of tax program requirements with practical debt structuring.
Understanding the Opportunity Zone Program
Before examining the financing side, a brief overview of the program’s mechanics is useful for lenders and developers who may encounter these projects from the lending side.
Investors who realize capital gains can invest those gains into a Qualified Opportunity Fund (QOF) and defer recognition of the original gain until a future tax event (typically a disposition of the QOF investment or December 31, 2026, whichever is earlier). If the QOF investment is held for at least 10 years, any additional appreciation generated by the investment itself is excluded from taxable income entirely.
To qualify, real estate must be located in a designated opportunity zone—areas defined by census tract designations established at the state and county level. The most common path to eligibility is the “substantial improvement test,” which requires the fund to double the adjusted basis of the property (often excluding land value). This standard is well-suited to heavy rehabilitation and ground-up construction. Alternatively, property that has never previously been placed in service (“original use”) also qualifies without the doubling requirement, making vacant land and raw land natural candidates for the program.
Why the Capital Stack Is Often Underestimated
One of the most consistent patterns in OZ fund work is that sponsors underestimate the complexity of their capital stack. Developers frequently arrive at the financing conversation with a project concept, an equity raise target, and an optimistic view of both their ability to attract investors and their refinancing prospects years down the road.
These gaps create real problems. A project that cannot service its debt without implausible rent projections will not succeed simply because it sits in an opportunity zone. The tax benefit adds value, but it does not transform an unworkable deal into a workable one. Experienced lenders and equity partners evaluate OZ projects on the same fundamental metrics they apply to any other transaction: debt service coverage, loan-to-cost ratio, cost projections, and the sponsor’s track record.
The non-recourse requirement common to QOF structures adds another layer of complexity. Non-recourse financing is available, but it generally comes at lower loan-to-cost ratios—typically 50% to 60% of cost rather than the 75% to 85% that might be available on a recourse deal. Sponsors who need to close that gap through mezzanine financing must account for the additional cost of that capital and stress-test their projections against realistic future refinancing conditions.
HUD-Insured Financing for OZ Construction Projects
For multifamily construction projects in opportunity zones, FHA/HUD-insured financing under HUD’s Section 221(d)(4) program offers distinctive advantages that merit serious consideration—particularly for projects where the sponsor plans to hold the property long-term.
Key Advantages of HUD Financing
Rate certainty from day one. Unlike conventional construction loans with floating rates and uncertain permanent financing terms, HUD construction loans lock in a fixed rate for the entire loan term—including both the construction period and the permanent phase. On a HUD construction-to-perm loan, the rate established at origination applies for the full 40-year permanent term that follows construction. This eliminates the refinancing risk that plagues conventional construction borrowers who must go back to market when the construction loan matures.
Higher leverage potential. HUD financing can reach up to 85% loan-to-cost on qualifying projects—and in cases where the developer is serving as general contractor, the GC fee can be contributed as equity, effectively pushing the loan-to-cost ratio even higher. This compares favorably to conventional non-recourse financing at 50%–60% loan-to-cost. Because HUD uses a 40-year amortization schedule rather than the 25–30 year schedules common in conventional products, the maximum loan amount supported by a given NOI is substantially higher.
Non-recourse structure. HUD-insured loans are inherently non-recourse, which aligns with the structural requirements common to opportunity zone fund investments.
Loan assumability. HUD loans are assumable by a qualified successor borrower for a modest fee. In a rising rate environment, an assumable loan at a sub-market fixed rate represents a tangible premium for prospective buyers, which can improve exit pricing.
Limitations of HUD Financing
Timeline. The HUD application and approval process for construction loans takes considerably longer than conventional alternatives—typically 12 months from initial application to closing. Sponsors must engage a HUD lender early in the development process, ideally when the project is entitled but before full permit-ready status. Working backward: a HUD lender typically needs six months of lead time before the permit is in hand, and closing occurs approximately three months after permit issuance.
Prevailing wage requirements. HUD-financed construction projects must pay prevailing wages, which increases labor costs in many markets. In some high-cost urban markets this differential is minimal; in others it represents a meaningful cost premium.
Statutory loan limits. HUD financing is subject to per-unit loan limits that vary by bedroom count and market. These limits are designed for affordable and workforce housing, not luxury product. Developers building high-end units in expensive markets may find that the HUD loan limit constrains leverage well below what the project’s debt service could otherwise support.
Minimum loan size. While HUD has no formal minimum, the cost of reports, audits, and compliance typically makes loans below $5 million on a refinance (and below $10 million on construction) uneconomical relative to conventional alternatives.
HUD and Refinancing: The Three-Year Window
A notable policy development in recent years enabled sponsors who built projects using conventional (non-HUD) construction financing to subsequently refinance into HUD permanent loans, with the three-year waiting period that had previously applied to such refinances being waived. This created an attractive option for developers who completed conventional construction and now seek the stability of HUD’s fixed-rate, long-amortization permanent financing.
For OZ fund investors planning to hold the property for 10 years to capture the full exclusion benefit, the availability of non-recourse HUD permanent financing with a 40-year term and no maturity date (unlike conventional loans that typically balloon after 10 years) is a particularly strong match.
Structuring the Capital Stack for an OZ Project
The right capital structure for any OZ project depends on the project’s specific financial profile. That said, several principles apply broadly.
The deal must stand on its own fundamentals. Tax benefits do not compensate for a project that cannot support its debt service or that depends on optimistic absorption assumptions. Opportunity zone investors—particularly institutional equity investors—evaluate projects on their intrinsic investment merits. If the tax benefit is the primary reason the deal pencils, that is a warning sign.
Plan the refinancing path from day one. For conventional construction loans, the interest rate environment at the time of refinancing is unknown. Sponsors who build to a tight yield-on-cost without adequate cushion may find themselves unable to refinance or pay off their construction and mezzanine debt when the loan matures. Stress-testing the refinancing scenario against higher future rates is not optional—it is essential.
Account for cost overruns. Construction costs consistently exceed initial projections. Underwriting should include meaningful contingency reserves, and sponsors should have a clear plan for how overages will be funded without disrupting the capital structure.
Address equity readiness before approaching lenders. Lenders who are evaluating an OZ project want to understand where the equity is coming from. A sponsor who has raised 20% of a 30% equity requirement is in a fundamentally different position than one who has raised 5%. Lenders who are comfortable bridging a modest equity gap with mezzanine financing will not take on projects where the equity plan is purely speculative.
Align vendor experience with program complexity. Tax credit programs, EB-5 financing, new markets tax credits, and OZ program requirements each carry their own legal, regulatory, and monitoring obligations. Sponsors who stack multiple programs on a single project need legal counsel, tax counsel, and capital partners with demonstrated experience in each applicable program.
Asset Classes and Geographic Trends
Multifamily—particularly workforce housing and affordable housing—has historically been the dominant asset class in opportunity zone development, for reasons rooted in the fundamental economics of residential demand. Industrial properties have also performed well, driven by e-commerce logistics demand. Mixed-use development that incorporates retail anchored by necessity-based tenants has found success in appropriate markets.
The program has proven far less hospitable for hospitality, office, and traditional retail development—asset classes that face structural demand headwinds independent of any tax program. Developers and lenders evaluating OZ projects in these categories should apply particularly rigorous underwriting standards and ensure that the fundamental real estate thesis is sound before layering in the tax program benefits.
Adaptive reuse—converting hospitality, office, or retail properties into multifamily residential—has emerged as a significant opportunity in many markets. HUD financing is available for adaptive reuse projects where rehabilitation costs exceed $18,000 to $20,000 per unit, making these conversions eligible for the same favorable financing terms as ground-up construction.
Working with Legal Counsel on OZ Fund Structures
The securities, tax, and regulatory complexity of opportunity zone fund formation requires experienced multidisciplinary counsel. At the entity level, QOF formation involves securities law compliance for the fund itself. At the project level, the 30-month substantial improvement deadline, the monitoring requirements through the 10-year hold period, and the interaction between OZ requirements and other financing programs (HUD, tax credits, EB-5) each present distinct legal considerations.
