How to read these numbers

Where the long-term numbers come from

Long-term figures come from 24 weekly snapshots of Calgary's public rental listings (Feb 9, 2026 to Jul 25, 2026). 'Weeks on market' is the week by which half of new listings have left the market (a Kaplan-Meier median), counting still-active listings. All rents are asking rents. Rooms for rent, storage, offices, parking, and vacation homes are excluded; basement and main-floor suites are included as their own property group.

Community-level rents use the latest weekly snapshot. The finer property-type-by-bedroom rent grid pools the last 8 weekly snapshots (each listing counted once at its median asking rent) so smaller cells reach a usable sample.

Where the Airbnb numbers come from

Short-term figures come from our Jul 18, 2026 Airbnb data snapshot, excluding hotels, B&Bs, and 28+ night-minimum listings. Nightly rates are each listing's median across weekly observations from Feb 10, 2026 to Jul 18, 2026 — not peak-season pricing. Occupancy is the share of the next 12 months already marked unavailable on the calendar (booked AND host-blocked), so estimated revenue is a gross upper bound.

Where the yield and supply numbers come from

Gross yield = 12 x the community's median asking rent for a property type (all bedroom sizes, pooled over the recent snapshot window) divided by the average CITY-ASSESSED value of matching dwellings. Assessments aren't sale prices, rents are asking not signed, and gross means before property tax, condo fees, insurance, vacancy, and maintenance — treat it as a comparison tool between communities, not a return forecast. Yield is strictly per property type (an all-types yield would rank communities by their housing mix, not their value). Yield cells need 8+ priced listings and 20+ assessed dwellings; basement suites have no yield (not purchasable separately).

Supply figures: active listings per weekly snapshot (the trend line), distinct listings seen over the whole window, new listings that first appeared after our first snapshot, and homes permitted = building-permit housing units issued over the last 24 months — new construction plus legalized basement suites; renovations of existing buildings and cancelled permits excluded (City of Calgary open data).

Why some communities are gray or withheld

Sample floors: weeks-on-market needs 15+ tracked departures; rent cells need 3+ priced listings (head-to-head rent cells 8+); Airbnb community stats need 10+ listings and 5+ per bedroom or type cell. Cells below the floors show as '—' rather than unreliable numbers.

A community leans short-term when its median head-to-head gross premium is 40%+ (roughly what Airbnb's higher operating costs eat), long-term when 5% or less, mixed in between. Communities without enough same-size listings for a head-to-head are uncolored on the map.

Communities below every floor are listed separately with what little we saw — in a tight community, three listings in five months IS the story.
