Should I sell or Refi

[BJ Gadway]

Ok so without even knowing I did so, I bought my primary residence a specifically the right time. 3/2.5 with 2 car garage 1600sq/f. Under current market conditions, my home has nearly doubled in value from time of purchase. We are however as a young family outgrowing the residence and looking to upgrade. So my question is "should I sell and use the proceeds to clear some debt, set up emergency funds and have a 20% down payment on new place and then save, plan and structure my relestate investing " or " should i refinance have the around 15% down payment on new home, clear about same amount of debt and same emergency fund, and fix the few minor repairs needed to rent out the home, with an estimated cash flow of $300" Thoughts, recommendations, tips, suggestions, any and all help would be much appreciated. I am new to real estate investing and am excited for what lies ahead.
