A single-family home carries no condo fees and no shared decisions with a condominium corporation, which appeals to a buyer who wants full control over renovations, a yard and parking. That control comes with full responsibility for the roof, the furnace and the driveway too.
A condominium or a semi-detached property usually asks a lower purchase price and, for a condo, a predictable monthly fee that covers exterior maintenance, which suits a buyer who wants lower upkeep or a smaller footprint over one who wants space and privacy.
Neither is the better buy in general. The better buy is whichever one fits your budget, your tolerance for maintenance and how long you plan to stay in the home. Get your hand-reviewed valuation from Joel Dyck.
