One of the most common questions we hear from new homebuyers is: “How much house can I afford?” It’s a great place to start—and we’re here to help you make sense of it, especially in a market like Sarnia-Lambton, where your dollar can stretch further than in many other regions of Ontario.

1. Get Pre-Approved

A mortgage pre-approval gives you a clear idea of your price range. Lenders (like credit unions and banks) look at your income, debts, credit history and down payment. If you’re not sure where to begin, we can recommend great local mortgage pros, or you can browse our free online business directory here.


2. Know the Full Costs

There’s more to owning a home than just the mortgage. You’ll want to consider property taxes, utilities, home insurance and maintenance. Here's a quick look at estimated monthly costs at three different price points:
