BC Assessment vs What Mission Homes Actually Sell For

Your BC Assessment notice is a tax document, not a price. For 2026 the typical Kelowna single-family assessment is $918,000 — down 2% from $938,000. Across these neighbourhoods together, the median detached home has sold above that figure in all twelve months since the date your assessment was calculated — never once dipping below it, and at the low point still 26% clear of it.

What the assessment is actually measuring

BC Assessment values every property in the province as of 1 July of the previous year. The notice that landed in your mailbox on 2 January 2026 is a snapshot of the market seven months before you opened it, produced by mass appraisal — a model applied across thousands of properties at once, not a person standing in your kitchen.

That model exists to divide a municipal tax bill fairly. It does that job well. It is not built to tell you what a buyer would pay for your specific home this month, and it does not claim to be.

The 2026 roll put the typical Kelowna single-family home at $918,000, down from $938,000 — a 2% decline. BC Assessment’s own deputy assessor described most Thompson Okanagan communities as landing in a −5% to +5% band.

What actually sold up here

Here is the median sale price for detached homes across these neighbourhoods pooled together — 3,974 sales since 2016, which is a big enough sample that one unusual month cannot move it much.

The weakest month in that whole run was September 2025 at $1,135,000, still 24% above the typical assessed Kelowna home. The strongest was February 2026 at $1,585,000, 73% above it. There is no month in the series where the two numbers are describing the same house.

Direction is a separate question from level, and it is the one people get wrong. Pooled across these neighbourhoods, July 2025 to July 2026 moved from $1,272,000 to $1,265,000 — essentially flat, half a percent down. The assessment roll said −2% city-wide. Those two are not far apart. What the roll cannot tell you is where in a $1.1M–$1.6M band your particular home sits, and that spread is worth vastly more than the percentage.

Why the gap is structural, not a mistake

Mass appraisal works from what it can see in a database: lot size, floor area, age, broad location. Up here, the things that move a price most are the things it cannot see.

• The view. Two homes on the same street with the same floor area can be six figures apart depending on whether the lake is in front of you or behind a roofline.
• Usable yard. Flat, level ground is genuinely scarce on the benchland. Where it exists, buyers pay for it.
• Build era and finish. A 2005 build and a 2021 build with identical square footage are not competing for the same buyer.
• Which side of the street. Elevation and orientation change what you see from the kitchen, and buyers price that difference precisely.

None of that is a knock on BC Assessment. It is the difference between a number produced for taxation across 450,000 properties and a number produced for one transaction.

What to do when your notice arrives

Every January, assessments land and people in the Upper Mission and elsewhere read them as a verdict on their equity. Some decide not to sell on the strength of a percentage that was measuring something else entirely.

A better sequence: treat the assessment as a tax input, check whether it looks reasonable relative to your neighbours for tax-fairness purposes, and if you actually want to know your market value, price it from comparable sales in your immediate area. That is a different exercise and it produces a different number.
