What this means if you're buying in Oshawa
Market conditions shape the negotiation; your income, debts and the stress test decide what you can actually borrow. This is the strongest rental-income market on the site, and the place where using it well matters most. Confirm whether an existing suite is legal and registered — it changes which lenders will use the income and how much of it. If you are buying as an investor rather than to occupy, expect a 20% minimum down payment: rental properties you do not live in cannot be insured. If you will live in one unit of a two-unit property, you can put down as little as 5%, which is a completely different proposition and one a lot of buyers here do not realise is available.
