How to get approval for multiple mortgages

[Lewis Janetos]

I am seeing a lot of people on BP with more than four mortgages at a time. My question is, how do you get approval for so many mortgages so quickly? My realtor previously told me that it takes two years to be able to count rental income on a property. If you are partnering with other investors, how am I seeing young people in the 20s and 30s with multiple properties at that point? I thought that just because you come up with the down payment doesn't mean you'll be approved because your income hasn't changed yet. Could someone please explain how they made this work and include some information around timelines?
