A 2020 build is 6 years old. The building is young. Several of its systems are not, and that is the part nobody thinks to check. Here is what tends to be true at that age, what each one costs in 2026 Canadian dollars, and the sentence to say to the agent.
Ordered by what tends to matter most.
Two system dates worth having before you offer
The building is 6 years old, and so is every system in it that has never been replaced. That is the part a listing photo cannot show you, because a replaced furnace and an original one look identical from the doorway.
All of these carry a date. The water heater has a rating plate near the top of the tank, usually with the date encoded in the serial number, and the furnace and the air conditioner both carry a dated label. Photograph them.
Say this to the agentHow old is the water heater, and is it owned or rented?
A young house is not the same as a young set of systems
A house of this age generally has copper or PEX supply, a breaker panel and double pane windows, so it carries none of the era hazards that older homes do. That is the part everyone notices. The part almost nobody checks is that the roof, the furnace, the air conditioner and the water heater age on their own clock, not the building’s, and on a house of this age at least one of them is usually further along than the house looks.
The ages are readable. The water heater carries a rating plate near the top of the tank with the date usually encoded in the serial number, and the furnace and the air conditioner both carry a label with a date on it.
Say this to the agentHow old are the roof, the furnace, the air conditioner and the water heater, and which of them are still the originals?
This is what is typical for the year. It is not a finding about this house.
Photographs of the panel, the basement and the water heater would tell you whether any of it applies here.
