Minimum family income to start real estate investment ?

[Bhavik Gorajiya]

Beginner question: I see lot of people making money in real estate investing. My personal interest is in rental property investment. how much minimum income needed to start real estate investing in British Columbia, Vancouver or Alberta, Calgary region. with current affordability I can only purchase one 2 bed condo. with current rental market its not possible to generate +ve cash flow with even 20% Downpayment. curious how people are making money or is this just real estate scam to sell properties?
