How we call the market
Inventory is low at 1.1 months of inventory, but only 17 sold in the last three months, too few to call a seller's market, so this is currently a balanced market. From August to October 2026, 17 detached homes sold, 6 sellers took their home off the market without relisting and 3 came back at a lower price — a 74% sell-through. Over August to October 2026, homes sold for a median 97.9% of their first asking price, and the median sold price per square foot was down 13.2% from the same months a year earlier.
What we measure, over the last three full months
- Months of inventory: homes for sale today, divided by the average number sold per month. Fewer months means less choice for buyers.
- Sell-through: of the sellers whose listing ended, the share who actually sold. A seller who takes their home off the market and doesn’t list it again within 60 days counts as not selling. A home that comes off and goes back on (often a day later, at a lower price) counts as a price cut, not a seller giving up.
- Sold vs. first asking price: what homes sold for, compared with the price they were first listed at. We follow a home back through any relists, because a relist starts a new MLS® listing and hides the earlier, higher price.
- Sales to new listings: homes sold for every 100 that came on the market. TRREB publishes this as its SNLR. Under 40% favours buyers and over 60% favours sellers.
- Price trend: the median sold price per square foot, compared with the same three months a year earlier.
How the call is made
- Seller’s market: under 3 months of inventory, at least 70% sell-through, and homes selling for 98% or more of their first asking price, or prices up from a year ago while homes sell for at least 96% of it. We also need at least 20 sales in the three months, because a handful of sales can swing the numbers.
- Buyer’s market: over 6 months of inventory, or under 50% sell-through (more sellers giving up than selling).
- Balanced market: everything in between, including low inventory where sellers are cutting prices, relisting or pulling their homes. We say it leans toward buyers when fewer than 40% of new listings sold or inventory is 5 months or more, and toward sellers when more than 60% sold.
Based on MLS® listings from TRREB. Area totals only. We don’t show a call when fewer than 10 homes sold in those three months. Relists are matched by address, so a home relisted under a differently written address counts as taken off the market. Private sales and listings not on MLS® aren’t included. This is a general guide to the area, not an appraisal or advice about a specific home.
Based on properties for sale & sold — rentals not included. Figures are a monthly rollup covering November 1–4, 2026 (month to date), refreshed with each MLS® sync — shown as of November 4, 2026.

What should buyers check?
