Should I not build my credit score up?

[Christopher Lugo]

Should I listen to Dave Ramsey's rule and not build my credit up. I want to start investing into Real Estate at a young age, Im only 20 right now and don't know if I should start to build my credit up. Dave Ramsey says that you can purchase a property with a zero credit score and still get a mortgage. Any tips or suggestions for someone starting at a young age would be an amazing help. Im located in northern New Jersey so any local investors that would like to help me get on the right track would be much appreciated. Thank you.
