To determine 'affordability' you will first need to know your taxable income along with the amount of any debt outstanding and the monthly payments. Assuming it is your principal residence you are purchasing, calculate 39% of your income for use toward a mortgage payment, property taxes, and heating costs. If applicable, half of the estimated monthly condominium maintenance fees will also be included in this calculation. Second, calculate 44% of your taxable income and deduct all of your monthly debt payments, including car loans, credit cards, lines of credit payments. The lesser of the first or second calculation will be used to help determine how much of your income may be used towards housing related payments, including your mortgage payment. These calculations are based on lenders' usual guidelines. In addition to considering what the ratios say you can afford, make sure you calculate how much you think you can afford. If the payment amount you are comfortable with is less than 39% of your income you may want to settle for the lower amount rather than stretch yourself financially. Make sure you don't leave yourself house poor. Structure your payments so that you can still afford simple luxuries.

A home inspection is a visual examination of the property to determine the overall condition of the home. In the process, the inspector should be checking all major components (roofs, ceilings, walls, floors, foundations, crawl spaces, attics, retaining walls, etc.) and systems (electrical, heating, plumbing, drainage, exterior weather proofing, etc.). The results of the inspection should be provided to the purchaser in written form, in detail, generally within 24 hours of the inspection. A pre-purchase home inspection can add peace of mind and make a difficult decision much easier. It may indicate that the home needs major structural repairs which can be factored into your buying decision. A home inspection helps remove a number of unknowns and increases the likelihood of a successful purchase.

A conventional mortgage is usually one where the down payment is equal to 20% or more of the purchase price, a loan to value of or less than 80%, and does not normally require mortgage loan insurance.

A minimum down payment of 5% is required to purchase a home, subject to certain maximum price restrictions. In addition to the down payment, you must also be able to show that you can cover the applicable closing costs (i.e. legal fees and disbursements, appraisal fees and a survey certificate, where applicable). Mortgages with less than 20% down must have mortgage loan insurance provided by either CMHC or GE.

Mortgage loan insurance is insurance provided by Canada Mortgage and Housing Corporation (CMHC), a crown corporation, and GE Capital Mortgage Insurance Company, an approved private corporation. This insurance is required by law to insure lenders against default on mortgages with a loan to value ratio greater than 80%. The insurance premiums, ranging from 0.60% to 4.5%, are paid by the borrower and can be added directly onto the mortgage amount. This is not the same as mortgage life insurance.
