The Vacancy Advantage: Dual-Track Sale for a Duplex + Penthouse ADU



The file
The building was a fully vacant duplex with a penthouse ADU above and an unwarranted garden in-law below: two units plus an ADU on paper, four units in practice. Full vacancy is rare, and it bought strategic room. Instead of choosing between selling the whole building or slicing it into TIC interests, I ran both campaigns at once, priced and sequenced so neither track undercut the other.
Presentation ran residential-grade: full staging, serious photography, floor plans and unit-level collateral of the kind usually reserved for single-family listings. That framing put the asset in front of end-users as a compound home with income, not a rental play. The buyer who won was an owner-occupant, above the top of the investor underwriting, and the deal closed at $4.325M without a fall-through.
Vacancy, ADUs, conversion paths: structure and timing decide the premium.
