This program is offered by the BC Government to help first time home buyers by helping you with an interest free loan to help with your downpayment. While it's still up to you to save the minumum 5% downpayment required for your mortgage, the Government will match your downpayment up to an additional 5% (home purchase price must be $750,000 or less). This loan is interest and payment free for the first 5 years, after which you can either repay the loan, or enter into monthly payments. It's a great way to get access to some low cost money to help you get started as a home owner!
