When you require a mortgage for more than 80% of the purchase price of a property, that mortgage must be insured by Canada Mortgage and Housing (CMHC) or GE Mortgage insurance. The premium charged by these company`s decreases as the down payment increases. When you finance your property at 95%, a premium of 3.75% is added to the mortgage. By increasing the down payment to 10% of the purchase price the premium can be reduced to 2.5%. If you can put down 20%, you can avoid any additional insurance fee. Depending on your situation there are ways that you can structure this financing to avoid the CMHC or GE insurance premium.

As mentioned above, when you put a 20% down payment on your purchase you can avoid the CMHC premium. More importantly the larger the down payment, the lower the amount of interest you will pay over the life of your mortgage. It is important to note that it may not be wise to stretch yourself to increase your down payment and end up borrowing on credit cards or a line of credit at a higher rate.
