SINGLE-FAMILY HOMES WITH ILLEGAL SUITES
Why Single-Family?
A single-family home with a suite is the classic entry point into this kind of investing: one primary residence, one basement or lower-level unit. It's usually where people start, whether that's living upstairs and renting the suite to help cover the mortgage, or buying it purely as a rental from day one. Because it still reads as a regular home to most buyers, it also tends to have the broadest resale pool of the three property types. That matters if your plans change down the road and you need to sell to someone who isn't specifically looking for an investment property.
Should You Buy One With an Illegal Suite?
Yes, but it depends. An illegal suite (a lower level that isn't registered with the city as a legal secondary suite) can still serve as a genuine mortgage helper. It also comes with real financing, insurance, and resale considerations worth understanding before you make an offer, not after. Some lenders won't count rental income toward your mortgage qualification, and your buyer pool narrows somewhat at resale, though it doesn't disappear entirely.
