Welcome to BP @Account Closed !! So glad to see you taking part in the forums. I visited our nation's capital recently, it's a fantastic town! Very hospitable people. ;)
I don't know if I agree or not that SFR is the best place to start investing...then again, I strongly suggest starting with whatever you're most comfortable with, so if that's SFR then go for it! My only concern is if you have a vacancy in a single family and it's your only property, you have 100% vacancy ie. no rent coming in that month (or two or three depending on the rental market), whereas with multifamily that risk is mitigated across all units.
My first rental was a triplex and I was always very happy with it. It didn't break the bank when I had a tenant leave suddenly (which only happened once), nor did I feel I had to rush into taking the first tenant that came along since nearly all the monthly expenses were covered by the other two units. It's never fun paying out of pocket to carry your investment property!
I'm sure whatever you decide you'll be successful at! As long as you get to know the market well and make sure the numbers work.
The next time I'm in Ottawa let's do a BP meetup!!
