Methodology
Most home valuation tools give you a single number from a black box. We don't. Every Realtii estimate triangulates multiple independent signals — and shows you all of them, so you can judge for yourself.
Signal 1
The most direct signal of what a home is worth is what similar homes recently sold for. We pull recent sales of comparable properties in your area — same type, similar size, similar age — and weigh them by how close they are to your home in both location and time. Older sales count less. Sales further away count less. The closer and more recent, the more weight.
Signal 2
The most local signal possible. For detached homes, we look at recent sales on your street. For condos and townhomes, we look at recent sales in your building. These are the most reliable indicator of what your specific block or building is worth, because they remove most of the variance that comes from neighbourhood differences.
Signal 3
Sold prices tell you where the market was. Active listings tell you where the market is right now. We look at what comparable homes near you are currently listed for — and how long they've been sitting — to capture present-day pricing pressure that hasn't shown up in sold data yet.
Signal 4
The province publishes an annual assessed value for every property in BC. Assessments lag the market — they're based on values as of July 1 of the prior year — but they're a transparent, publicly available anchor that every estimate should reconcile with. We use the assessment as one independent check on our other signals.
Signal 5
We maintain a monthly price index for every area in BC, going back roughly a decade. This shows how values in your specific area have moved over time, and lets us adjust older sales forward to today's market. A house that sold for $1.2M in 2018 isn't worth $1.2M in 2026 — the price index tells us what that same house is likely worth now.
Signal 6
For newer builds — homes built in the last few years — comparable sales are often scarce or unreliable. For these properties, we use replacement cost: the value of the land plus what it would cost to rebuild the structure today at current construction prices. This signal acts as a floor on value for new construction where market comps are thin.
Every Realtii estimate triangulates these signals into a single value. We don't weigh them equally — we weigh them by how reliable each one is for your specific property. A detached home in a busy market gets weighted more toward recent sales. A new build with few comps gets weighted more toward replacement cost. A property in a quiet area where assessments track closely to market gets weighted more toward the assessment.
Every estimate also comes with a confidence range — the gap between the lowest and highest signal. When the signals agree, the range is tight and our confidence is high. When they disagree, the range is wider and we tell you so. We never hide that.
The number you see isn't a guess. It's the result of six independent signals, each weighted by reliability, and shown to you so you can judge for yourself.
Realtii is built on more than 10 million records from publicly available property data across British Columbia. That includes provincial assessment data, recent sales, active listings, and historical transaction records. We refresh the data continuously so your estimate reflects the most current market conditions we have.
No data is sold. No address is shared. Your portfolio stays yours.
