A unit-by-unit underwriting of a Phoenix eight-unit property combining performing units, vacant units and units mid-renovation.
This acquisition profile examines asset strategy, underwriting method, transaction structure, and value-creation considerations. Counterparty and pricing details are not disclosed.
This acquisition profile examines an eight-unit residential property in the Phoenix market containing performing occupied units, vacant units, and units requiring improvement before they can generate income. It sets out AceStone Capital Group's underwriting methodology; specific counterparties and pricing are not identified.
A single multiplier applied to gross rent assumes homogeneity across units. In a mixed-occupancy building, the units are not comparable to one another: one produces contractual income today, one produces none but could within weeks, and one produces none and will not until capital is spent. Applying one metric across all three states either overpays for non-producing space or ignores capacity that genuinely exists.
Applied exampleSee how this played out in Duplex Acquisition: Mixed-Occupancy Two-Unit Asset, Phoenix — a residential acquisition in Phoenix, AZ.
Each unit is assigned a state — performing, vacant and rentable, or renovation-stage — and each state carries its own income assumption, cost assumption and timing assumption. Only after each unit is modeled individually are the results aggregated into a property-level figure. The aggregate is an output of the unit analysis, never an input to it.
For occupied units, diligence covers executed leases, remaining term, expiration dates, deposit ledgers, concession history, and collections rather than stated rent. These units establish the property's demonstrated income and also its demonstrated rent level, which anchors the comparable analysis for the non-producing units in the same building.
Applied exampleSee how this played out in Selling an Inherited Property in Florida — a residential acquisition in Florida.
Vacant units in rentable condition require a turn scope and a lease-up interval. Renovation-stage units require a defined construction scope, contractor availability, potential permitting or inspection, and a materially longer path to income. Each unit is scoped by walk-through rather than by extrapolation from another unit, because finish level and prior work vary within the same building.
Achievable rent is set from leased comparables in the immediate submarket, adjusted for unit size, bedroom count, cooling configuration, covered parking, and finish level. In this market, cooling capacity and condition are a rent determinant, not a detail, and a renovation premium is credited only where the renovation scope actually delivers a comparable finish level.
Applied exampleSee how this played out in Cash Offers vs. Traditional Listings: What Sellers Should Know — a residential acquisition in National.
Cost is built bottom-up from the scoped work per unit plus building-level items serving all eight units, with a contingency appropriate to the uncertainty of opening a unit already partially altered. Timeline is set from observed contractor availability and observed lease-up periods, then converted into carry — taxes, insurance, utilities and debt-free holding cost — across the interval.
Expenses are normalized to professional operation: market management, a maintenance allowance appropriate to the unit ages, per-unit reserves, owner-paid common-area utilities, water and sewer, landscaping suited to desert maintenance, re-quoted insurance, and property tax re-underwritten on a post-transfer basis rather than carried at the seller's current assessment.
Current economics reflect only performing units against the full normalized expense base — a deliberately unflattering figure, and the honest one. Stabilized economics reflect all eight units at documented market rents against the same expense base. Basis sits below stabilized value by the full amount of renovation cost, lease-up carry, and a return for the execution risk of delivering that outcome.
The material risks are renovation scope expansion in partially altered units, contractor availability extending the timeline, lease-up periods exceeding observed norms if submarket supply increases, cooling system failure during stabilization, post-transfer tax reassessment, and rent assumptions on renovated units drawn from a comparable set the finished product will not match.
Multifamily underwriting cannot be reduced to a single rent multiplier. In a mixed-occupancy building, value is the sum of eight separately modeled unit outcomes, discounted for the cost and duration of delivering the ones that do not yet exist. Owners of comparable assets can review parameters on the multifamily acquisitions desk.
Mixed-occupancy assets reward buyers who scope precisely and penalize those who average. The framework above reflects AceStone Capital Group's underwriting posture on assets of this profile.
