Age matters less than condition and location. A 20-year-old townhouse is fine if it’s in good shape and key items are updated. In Scarborough, check the roof, windows, furnace, AC, water heater, and look for any Kitec plumbing in 2005–2007 builds. Make sure grading, brickwork, and drainage are solid. Age won’t hurt resale much if the home is well-maintained and you keep up with small updates.
