I get asked this question quite often so here is the answer and I might add it is the same for a freehold property as well as a condo.
Answer: With the changes from CMHC, the minimum amount of your downpayment depends very much on your employment situation and the purpose of the purchase. If you are self-employed you will be required to put down a minimum of 10%. If you are purchasing the property for the sole purpose of renting out the property and not living in it at all, you will need a minimum of 20%. If you are fully employed, not self-employed, and plan to live in the property as your principle residence you will need a minimum of 5% down payment.
If you have questions regarding any part of the home sale or purchase just drop me a line.
