Deal Structures
Opportunity Zones
Institutional Opportunity Zone underwriting — fund structuring, investor tax mechanics, the 10-year hold, and substantial improvement qualification.
Opportunity Zones are a tax-driven structure, not a real estate strategy — and that flip changes how the deal pencils. A Qualified Opportunity Fund offers three layered benefits: temporary deferral of an embedded capital gain, a basis step-up on the deferred gain, and complete exclusion of post-investment appreciation after a 10-year hold. Each benefit comes with strict mechanics: the 90% asset test on the fund, the QOZB safe harbor on the operating entity, the working-capital plan that lets a development deal qualify, and the substantial improvement / original use rules that decide whether an acquisition counts. As the December 2026 deferral deadline approaches, the question for institutional capital is whether the after-tax IRR uplift compensates for the structural friction and the location constraint.
These four articles walk the OZ stack from fund to exit. Start with OZ Fund Structuring if you are forming or diligencing a QOF. Investor Returns is the after-tax math investors actually price on. Exit Timing covers the 10-year hold calendar and the December 2026 deferral inflection. Development vs Acquisition is where most qualification calls are made — and where most deals fail the substantial improvement test.
