27, no net worth, considering commercial RE as a career.
There was a post on /r/personalfinance a few days ago that got taken down, and it was very intriguing to me - this guy used small properties ($500K - $1M), in cities with populations less than 300K, had about 12 of them, and was getting about 30% return on them using NNN leases.

I would love to hear from you folks about how I would start a career in this business. I'm aware that the "cost of entry" is high - I would need to have at least $100K as a 20% down payment on a $500K property - but what other advice could you give me about how to get started?

Thanks everyone. :)
