Buying Your First (and Second, and Third) Rental Property

[Jennifer Katherine De Loughy]

How do you buy your first rental property? And if you are successfully collecting timely rent on it, enough so you don't need a traditional job outside of being a landlord, how do you buy your second rental property? 

Let's say I want to buy 10 rental properties - one at a time - and I want to be a career landlord/real estate investor. How would I go about doing that without a traditional job? Without income outside of rent?

Any and all resources regarding this information are greatly appreciated.

I am completely new - please be gentle!
