Why a pledge of equity fails the REIT asset test where a mortgage passes
A recurring structural question in private credit vehicles: an offering memorandum will often carve mezzanine loans out of the REIT sleeve and route them into a parallel vehicle, even though a mezz loan is economically a claim on the same building, sometimes at a lower last dollar than a B piece the REIT does hold. The mechanism is statutory, not just cautious drafting. REIT qualification tests look for interests in mortgages on real property as qualifying real estate assets and mortgage interest as qualifying income. A loan secured by a pledge of equity in a property-owning entity is not a mortgage on real property in the strict sense, so it has no clean home under the asset and income tests. The statute names mortgages specifically and is silent on pledges of equity, which is the source of the ambiguity managers cite. In practice, managers dealing with this either hold the mezz position below a taxable REIT subsidiary and accept the entity-level tax that comes with it, or they use preferred equity instead of mezzanine debt to get comparable economics without tripping the REIT qualification tests. Which route a given manager takes usually comes down to how much yield drag they are willing to absorb versus how much complexity they want in the structure.
