Can't Afford Down Payments? Need Advice

[Brandon White]

Hello! My name is Brandon, i'm from Canada and i'm new to real estate investing. 

As I do more and more research on people who have acquired multiple investment properties in a reasonable amount of time I have to wonder how did they manage to afford all those down payments? A non owner-occupied property must have at least 20% down which can be 30k or a lot more.

I have heard of HELOC's but you don't know if the property is going to appreciate in 1-2 years and if it does, by how much?

Any advice or tips on how in the future I can afford multiple down payments would be appreciated very much.

Thanks
