Any resources to learn about debt-free investing?

[Kate Johnson]

New member here.  I'm a military spouse and currently a stay at home mom, but we are interested in  learning about real estate investing. I'm of the "I hate debt" persuasion.  Are there any real estate books or experts (with websites, blogs, etc) that talk about investing in real estate by using only cash?  I know there is no shortage of info about using debt to your advantage in real estate transactions.  I'm interested in other opinions.  

I'd appreciate any info y'all have.
