10% down wont be feasible since you'll hit CMHC insurance... with today's rates the way they are still good at least until november. Its going up around then... if you get a variable close most banks are offering P+0.40 and P+ 0.60 for open variable. P= prime rate set at 2.25%. as for affordability or purchasing as a rental property make sure when you do apply for the mortgage just apply as a second home purchase rather than rental propery cos the LTV (loan to value) for rentals is 50% for most banks where as for second home can be same as your regular mortgage at 80% depending on how much money you make. good luck with your purchase
