I just started reading "The book on rental property investing"  2nd up is a book named "Rich Dad Poor Dad" .

With traditional lending you have a couple options.1. 2 mortgages a traditional 20% down mortgage with a second mortgage to cover the 10% extra you need. 

According to Rich Dad Poor Dad, I received a mixed message.

Am I limited to more traditional bank financing until I start an LLC?

I took out a traditional 30yr mortgage with 20% down.

No issue, but why not just get a traditional mortgage? 

The term “advertising,” for purposes of this rule, in addition to traditional print, radio, and television advertising, also includes, but is not limited to, sources of communication available to the public such as signs, flyers, letterheads, e-mail signatures, websites, social media communications, and video or audio recordings transmitted through internet or broadcast streaming.

In terms of the books, start with "Miracle Morning" and "Think and Grow Rich". 

If you haven't already read a book about investing maybe rich dad poor dad etc.

The financing is also easier (traditional home loan, no need for construction loan, etc.).
