Saint-Hyacinthe Plex Share: Nearly Six in Ten Recorded Sales

House hunting in Saint-Hyacinthe, you may notice more duplexes and small apartment buildings than single-family homes. Recorded sales back that impression: in our database, plexes (Quebec's term for small multi-unit buildings, from duplexes up) make up most transactions, well ahead of houses. For a general picture of the city, see our Saint-Hyacinthe real estate market overview; this article isolates one mechanism, the weight of plexes in a regional market's sales, and what it means for a buyer.

301 sales over about 30 months

The figures come from CourtiConnect's comparable sales database for the Saint-Hyacinthe sector, rentals excluded. Sales in the database run from November 6, 2023 to June 2, 2026, about 30 months: 301 sales in total. Only aggregates are published; no individual sale is shown.

Plexes are sorted into three separate groups: duplexes, triplexes, and buildings with 4 or more units. Ten sales of an "other" type, mostly buildings of 6 to 12 units, are kept apart and not added to the plexes. Prices quoted are medians: the value that splits a type's sales into two halves.

178 plexes out of 301 sales

• Plexes, all groups combined: 178 sales, or 59.1% of the total.
• Houses: 81 sales, or 26.9%.
• Condos: 32 sales, or 10.6%.
• Other (kept apart): 10 sales, or 3.3%.

For every house sold in the database, about 2.2 plexes sold. Adding the ten "other" sales would lift the share to 62.5%. We keep it at 59.1% so as not to mix buildings of very different sizes into the plex figure.

Within plexes, 4-plus-unit buildings lead

• 4 or more units: 80 sales, or 44.9% of plexes.
• Duplexes: 64 sales, or 36.0% of plexes.
• Triplexes: 34 sales, or 19.1% of plexes.

Buildings with 4 or more units alone account for almost as many sales as houses: 80 against 81. The triplex, often seen as the typical Quebec plex, is the smallest group here.

Median prices by type

• Condo: $435,000 (32 sales).
• House: $498,000 (81 sales).
• Duplex: $524,950 (64 sales).
• Triplex: $558,250 (34 sales).
• 4 or more units: $737,500 (80 sales).

The median duplex sold for $26,950 more than the median house. For a buyer with a budget around $500,000, houses and duplexes sit at neighbouring medians. The data gives medians only, not the spread of prices within each type, so it says nothing here about how much the two distributions overlap.

Sales of $500,000 and up make up 65.4% of the total (197 of 301), and only 18 sales closed under $400,000. The weight of plexes and the weight of sales above $500,000 go together in the database, but the published aggregates do not cross property type with price range; this article does not claim one explains the other.

What these shares do not say

• The database is not the whole market. These shares describe sales recorded in CourtiConnect's database. They do not necessarily measure the plex share of every transaction in the city.
• No trend over time. Sales are not spread evenly over the 30 months: a single sale in the last quarter of 2023, 115 in the first two quarters of 2026. We therefore publish no quarter-to-quarter change in prices or shares.
• Incomplete selling times for plexes. The database has a selling time for only part of the plexes: 13 of 34 triplexes and 41 of 80 buildings with 4 or more units. Those selling times are not used here.
• One sector, one window. These shares do not compare directly with another sector covered over a different period.

What a buyer can take from it

For a plex buyer, the database holds enough comparable sales in each of the three groups to position an asking price against buildings of the same size rather than the market as a whole. How a first purchase of this kind works is covered in our article on buying a first plex in Quebec.

For a house buyer, houses are a minority of the database's sales: 81 of 301. Comparables are fewer, so it pays to pick them carefully, by area and by construction period, rather than lean on an overall median. Either way, these figures help position a project; they do not replace an analysis of the specific property before you sign a promise to purchase (Quebec's term for a written offer).
