A mixed-use property is not one income stream with one set of risks. It is two or three property types stacked in a single building or on a single parcel, each with its own tenant profile, lease structure, and operating economics that happen to share a roof, a parking structure, or a common-area budget.
Ground-floor retail, office floors, and residential units above do not respond to the same demand drivers. Retail sales can weaken while the residential units above stay fully leased, or an anchor retailer can vacate and drag the whole building's parking, security, and common-area cost onto a smaller income base.
Underwrite a mixed-use DST as if it were several separate small properties sharing one balance sheet, not as a single asset with one blended cap rate. The blend can hide a weak component behind a strong one.
Break the rent roll into retail, office, and residential components and evaluate each against its own market comparables. A blended average rent per square foot across three different use types tells the reader almost nothing about whether any one component is priced correctly.
Check lease term structure by component. Retail and office leases typically run multi-year terms with escalations and expense reimbursements, while residential leases are usually short-term and reset to market far more frequently, which changes how fast each layer's income can move.
Identify whether any single tenant, such as an anchor retailer, supports a disproportionate share of common-area cost recovery for the other components, since that tenant's departure can raise costs for everyone else in the building.
Review how the building allocates shared HVAC, elevators, parking, security, and structural maintenance across retail, office, and residential components. A capital repair driven by one use, such as a parking structure serving retail customers, can be billed in part to residential tenants who never park there.
Confirm the allocation methodology in the reimbursement provisions of each lease type and whether it has produced disputes or under-recovery historically. Allocation formulas written years apart, as leases were signed and renewed at different times, do not always reconcile cleanly.
Ask how a major building system failure, such as an elevator or fire-life-safety system serving all uses, would be funded and how quickly repairs could proceed given the operational needs of the different tenant types sharing that system.
Confirm the zoning and any conditional-use permits that allow the current mix of uses, and identify whether replacing a vacated retail or office component with a different use would require a new approval, variance, or public hearing process the trust does not control on its own timeline.
Review any condominium or reciprocal easement agreements if the components are separately owned or financed, since these documents can restrict signage, hours, exterior changes, and even the categories of business permitted to lease the retail space.
Ask what happens if a component becomes functionally obsolete, such as office space that cannot be re-leased at any achievable rent, and whether the property's zoning and physical layout would even permit conversion to a more marketable use.
Lenders typically underwrite mixed-use debt against a blended and often more conservative view of each component's income durability, and proceeds can be lower relative to total revenue than a single-use property with comparable gross income.
Review whether the loan treats the components as a single collateral pool or imposes separate covenants or reserve requirements by use type. A weak retail component can trigger a cash management provision that affects distributions from the healthier residential or office income.
Stress a scenario where one component underperforms while the others hold steady, and confirm the loan and trust documents describe how that partial shortfall is absorbed without assuming an ordinary capital call from investors.
Model a sale where a prospective buyer discounts the building for its weakest income component rather than crediting the blended average the sponsor may present at acquisition. Buyer pools for mixed-use assets are typically narrower than for single-use properties of comparable size.
Review recent comparable mixed-use sales in the market, not single-use retail or office comps, since cap rates and buyer appetite for hybrid assets can diverge meaningfully from either component in isolation.
Confirm the trust's disposition strategy accounts for the possibility of selling components separately if that produces a better outcome than a single whole-building sale, and what approvals that path would require.
