Real estate license and out of state investing

[Eangelic San Agustin]

I currently live in Washington state and I plan on living here for about 5 more years. I do want to invest in out of state properties as I would get more ROI. I'm thinking about getting my real estate license in Washington. Main reason for that being so I can accumulate at least 2 more properties under my belt, granted that the price is right. Does access to MLS just include the state that I'm licensed in or all the states in the country? What 2 states/cities would you recommend looking into for out of state investments?
