If you own a house in Keystone right now, here is the honest truth: your home is sitting at an average HonestDoor Price of $1,724,236 - and the city's tax assessment is almost certainly not keeping up. Prices are holding strong, Keystone is one of the priciest addresses in Mission, and the rental numbers are genuinely impressive. Here is what you actually need to know.
We are working with houses here in Keystone, and the story is straightforward. The average sale price is sitting at $1,565,000, essentially flat from last month. One property traded hands in 2026 so far, which tells us this is a low-volume, high-value pocket - not a place where homes are flying off the shelf every week, but a place where the homes that do sell command serious money.
One thing worth flagging - the predicted value of $1,716,573 is running slightly below the 3-month moving average of $1,721,492. That is a small dip, and it is worth watching. We are not in freefall, but the market is taking a breather. The recent value change of -1.66% confirms that. Not a red flag, but not a reason to wait forever either.
On the rental side, we look very good compared to our neighbours. An estimated $6,047 per month in rent and an Airbnb rank of 2nd in all of Mission - that means Keystone is one of the top short-term rental spots in the district. At roughly $300 per night on Airbnb, that is real income potential for anyone thinking about this as an investment property.
Keystone is the premium option in this corner of Mission. Here is how we compare to the neighbourhoods right next door:
Keystone commands a $246,000 premium over Silverdale, the next closest neighbourhood. That gap is not accidental - it reflects what buyers are actually willing to pay to be here. Our price rank of 2nd out of 10 neighbourhoods in Mission confirms it. We are near the top of the leaderboard on value.
The honest counterpoint: our growth rank sits at 7th out of 12 comparable neighbourhoods. That puts us in the below-average tier for recent appreciation. So we are expensive and prestigious, but we are not the fastest-moving market in Mission right now. Both things can be true at once.
Here is the thing about government assessments - they are backward-looking. They are calculated from data that can be 12 to 18 months old by the time it lands in your mailbox. In a neighbourhood like Keystone, where the average HonestDoor Price is $1,724,236 and the predicted market value is $1,716,573, the gap between what the city thinks your home is worth and what a buyer would actually pay can be significant.
The HonestDoor Price is updated in real time using current transaction data, market trends, and comparable sales. It is the number that reflects what is happening right now - not what happened last year. If you are making any financial decision tied to your home's value, whether that is refinancing, selling, or just understanding your net worth, the HonestDoor Price is the number to trust.
A rental yield of 3.93% on a property in this price range is considered moderate - it is not a cash-flow machine, but it is a solid long-term hold. And with Airbnb income potential ranked 2nd in Mission, the short-term rental angle is genuinely worth exploring if you have a property sitting underutilized.
If you are thinking about listing in Keystone this summer, here is the straight talk. You are sitting on a high-value asset in a low-inventory neighbourhood. One transaction in 2026 means there is almost no competition from other sellers right now. That is actually good news for you - a motivated buyer does not have many options in Keystone.
The slight downward drift in the 3-month moving average and the -1.66% recent value change suggest that waiting too long is not a free option. Markets that are taking a breather can keep cooling if broader conditions shift. Listing while you are still ranked 2nd on price in Mission - and while Airbnb demand keeps Keystone on buyers' radar - puts you in a strong position.
The bottom line: Keystone is a prestige address with real rental upside and very little seller competition right now. If selling is on your mind, this summer is a reasonable window to move. Check your HonestDoor Price first - it will give you a far more accurate starting point than any assessment notice sitting in your filing cabinet.
