HALF DUPLEX HOMES WITH ILLEGAL SUITES
Why Half Duplex?
A half duplex, also called semi-detached, is one side of a two-unit building, your own title, your own suite potential, with a shared wall to the neighbouring unit. Structurally and as an investment, it's a lot like a single-family home with a suite. The real difference for buyers comes down to price: a semi-detached home typically costs less than a comparable detached single-family home in the same neighbourhood, which can mean more room in your budget for the suite itself. There's one more shared surface to be aware of, the wall to the neighbouring unit, but if you're already comfortable with the shared floor and ceiling between a main home and its suite, a shared wall isn't really a different kind of consideration, just one more of the same kind.
Should You Buy One With an Illegal Suite?
Yes, but it depends. An illegal suite (a lower level that isn't registered as a legal secondary suite with the city) can still work as a genuine mortgage helper here, same as it would in a single-family home. The same financing, insurance, and resale considerations apply, worth understanding before you make an offer, not after. Some lenders won't count the rental income toward your mortgage qualification, and your buyer pool narrows somewhat at resale, though it doesn't disappear.
