How to team up or get a loan for a rental property

[Randall Re II]

I'm currently oveseas right now and don't have a w-2. I have time on my hands to research markets and find rental properties that would work for long term and airbnb. The issue I am running into is with no w-2, can't get a loan. What's the best way that I see so many people scale to several properties with no to low w-2 wages for loans? The money is the only thing slowing me down. I currently have 1 long-term rental that I'm doing pretty good on.
