New investors in multi-family

[Pretty Khare]

Is there a good way for rookies to get to 10+ doors in a couple of years Without house hacking and without putting in hundreds of thousands of dollars in down payment? I feel like the requirement to put 25% down on multi families limits the amount of deals you can do. 

Would be great to hear from people who were in my shoes a couple of years ago how they were able to scale from 0 to 10+ doors quickly. Thanks
