The variable rate is like 3%....try asking for that at one of the big 5 banks and they'd laugh you out the door.

They also have a line of credit (5.75%) available as well -- always handy for repairs, etc.
To get a mortage for rental property you need 15% down, not 5%, which you'd pay if the house was to be your residense. Also, try to live in it for at least 6 months after the purchase (or at least send all your mail there) -- you'll pay less tax if you're living in the house as opposed to renting it or leaving it unoccupied.
My brother-in-law bought a house when he was 20. It was a peice of shit, but he worked on it for 5 years and sold it for a $40,000 profit. So yeah, ou can make a nice chunk of change off a house, but keep in mind that it'll take a few years before you recoup the inital investmet. A safe bet is to get a good house that needs a
little work -- spruce it up, live in for a bit (or rent it), and then sell it 5-10 years down the road.
I'm looking at buying one in the next year myself...
