If you're like most buyers, a home is the most expensive purchase you'll ever make, and you will likely need some form of financing. Knowing how home cost relates to mortgage payments can be a great asset when looking at homes.
I would be happy to refer you to some very good mortgage contacts that I have used extensively in the Ottawa area, or to help you in any other way I can to secure the best possible rate for your home purchase.
Also, the Ottawa Real Estate Board has a Mortgage Calculator. This calculator is a great reference and helps you to determine what your mortgage payments will be based on purchase price, down payment, interest rate and mortgage term.
