This is a very interesting topic, very broad and over reaching. I'll chim in with a few points. It's kinda like saying, hey I want to be rich, how do I do that? But then not having a quantitative goal to actually define what rich is. Like others have said, do you want to quit your job? Well that is easy... replace your current monthly income with rental cash flow or with profits from a big flip. If you earn 100k in your day job, that's a bit more difficult than replacing a 40k a year job. Do you want financial freedom? Well that's different for everyone, you may want a 13000sqft house with an infinity pool, and a garage full of Lamborghinis. I feel like I have financial freedom, and I dont have any of that stuff. But I can go snowboarding with my friends on a Wednesday, or spend a month in Barbados if I wanted to. So is freedom having 2 million in the bank. Or 10 million. You may be looking for generational wealth building, so you can leave your kids something. Or pay for their schooling, or a house for them.
So there are so many opportunities in real estate investing, and different ways to get there. Everyone's situation and experience is different. It's hard work, and a little bit of luck, I'd say. You just have to find what works for you. Good luck.
Oh, I also grew up in Mississauga, but I now live in Scarborough
