I work for a building materials company now and took their online game from Zero to very engaged in the past few years and it's been really fun.

I am not finding much material online or a book to study from.

I have read a lot of posts on Residential Assisted Living, that I am considering getting involved in, and seems like many of the posts make reference to RAL Academy and noted that there is an online version and in person version . . . wondering if any of you have taken either and if you would recommend one over the other and why.

Joining local meetups and online investor groups can also help you make valuable connections and find the right opportunities.Good luck!

Since you’re interested in learning more about commercial real estate (CRE), consider a mix of reading books, enrolling in online courses focused on real estate investing. 

Start by networking through local meetups, REIA groups, and online communities like BiggerPockets to connect with experienced investors.

Can't find much online....  

If you were going to focus your time on learning something, I'd say getting familiar with a bookkeeping platform (like Quickbooks Online) would be the best bang for your buck.
