What your unit re-rents for the day you leave

In BC your rent increase is capped while you stay. When the tenancy ends, the next tenant's rent is negotiated freely. CMHC measures how big that jump actually is, so this applies the measured premium to your rent instead of asking you to guess a market number.

What this number is, and what it is not

CMHC reliability grade 'b'. CMHC grades each published figure from a to d, where a is best. A grade of 'b' means very good: the estimate is solid enough to publish and to reason with, but it is a survey result with sampling error, not a count of every lease.
23.6% is a Vancouver CMA purpose-built average. It is one number for the whole census metropolitan area. It is not a quote for your building, your block, or your unit. A specific landlord can ask more or less than this.
Purpose-built rental only. These figures cover buildings constructed as rental apartments. Rented condominiums are surveyed separately and behave differently, so if you rent a condo the premium above does not describe your situation.
This is an estimate of a market outcome, not a prediction about you. It multiplies a regional average by the rent you typed. It knows nothing about your unit's condition, size, or how your landlord prices.
