Duplexes for Sale in Calgary
Listings use “duplex” three different ways and the price bands barely overlap. Terms first, live listings second, honest underwriting third.
A full duplex is both sides on one title — the true small-multi investment, one purchase producing two rentable homes. A half duplex is one side with its own title, which functions as an attached house and prices accordingly. Add duplexes with legal secondary suites and one “duplex” search spans three products with different financing, bylaws and returns. Underwrite with CMHC zone-level rent data and honest operating costs, treat every worked example as illustrative rather than promised, and confirm suitability with licensed advisors.
Full duplex, half duplex — the terms first
Calgary listings use “duplex” three ways, and the price bands barely overlap: a full duplex (both sides, one title — the true small-multi play), a half duplex (one side, your own title — effectively an attached house), and duplexes with legal secondary suites stacking two rentable units per side. Search results mix all three; know which you’re underwriting.

The numbers that matter, and where they come from
Underwriting a Calgary duplex takes three inputs: realistic rent (CMHC publishes zone-level survey data — the deal analyzer uses it), operating costs (tax, insurance, maintenance — the analyzer estimates them honestly), and your financing. Any worked example you see anywhere — including from me — is illustrative, not a promised return; Calgary rents and prices both move. Suitability for your situation is a licensed-advisor conversation, not a webpage’s.
