One thing I want to mention is that these books and podcasts serve for more than just a knowledge base, they give you the nerve to jump over that phycological fear barrier, which In my opinion keeps more people out of the game than lack of knowledge or skill.

Someone who has handyman skills and who could do rehab/handyman work, a little project management and GC type work as well under my general supervision.

I knew nothing but I got to the point that I now have serious remodeling skills.

Something to keep in mind as a skilled and hungry real estate investor is that patience is also an important trait.

I like RE because I can fix stuff with my hands, but if an RE investor doesn’t bring a special set of skills to the table such as being able to source discounted properties, force appreciation through sweat equity, consistently making deals like the one you described in your other post, etc., they may be better off focusing on their day job and loading up on dividend stocks. $500/month cash flow and $70k profit on a single subject to deal is not the norm. 

Even skilled workers will become scarcer. 

When it comes to the skilled trades (plumbing, HVAC, electrical), I’ve got my bases covered.

But to be honest with you, If you do not learn some construction skills, your progress will be a lot slower!

They are both completely different, require different skill sets and education, require different time commitments, etc. 

That skilled is used in every aspect of real estate investing ... if you plan on scaling ... 50 properties or more.
