Did you know that you can borrow up to $25,000 from your RRSPs interest-free?
Yes, you read that correctly. Interest-free, as in zero interest.
And you can even take a long time to pay it back. You are borrowing it from yourself after all.
As you are calculating how much you can afford to put down on your home purchase, keep in mind any funds you may be able to draw from your RRSP accounts.
