Scaling business so quick-NYC edition

[Michael Charles]

So I have seen some pretty good threads about "how do you scale your business so quickly"  see link https://www.biggerpockets.com/forums/311/topics/12...

and some other threads as well and they have been greatly informative. My question is for anyone that has scaled quickly in NYC. How they did it and any advice. I know real estate is not a get rich quick scheme, but I am interested to here stories about how people have succeeded in higher price point markets starting from scratch. I live in Queens now, and have been starting to look again into possibly house hacking into a multi family to start out. I thought about out of state investing in cheaper areas but I would like to stay in the 5 boroughs. It just seems hard to fathom scaling fairly quickly in such expensive markets. I have heard stories of people doing this and I would love to hear some feedback. Thanks!
