Rental Income portfolio building

[Philip Katz]

Most success stories here are from people who buy properties that need some work, unlocking value. I'm curious, are there any people here who manage to build a portfolio WITHOUT any rehab work at all? I'm in that spot because I have no skills or time for any kind of rehab work. 

But when I look around for rental property, I have a credit-limited amount I can borrow - which is great for my first rental property. But that's it. How do I grow from there if I can't borrow anymore? 

I'm very eager to follow success stories of others like me - people passively managing real-estate portfolios.
