Mountainside, Burlington Homes for Sale & Real Estate

Inventory is low at 1.2 months of inventory, but homes are selling under their first asking price and prices aren't rising, so this is currently a balanced market. From July to September 2026, 17 detached homes sold, 5 sellers took their home off the market without relisting and 4 came back at a lower price — a 77% sell-through. Over July to September 2026, homes sold for a median 95.0% of their first asking price, and the median sold price per square foot was down 15.1% 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.
• 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.
• 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.

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.
