What is the process in buying a home?

I want to buy a new home for my family. I need a home good we have five in our family. I have a 14 year old boy, 9 year old girl, and 3 year old boy. My wife loves to cook so she needs a big space in the kitchen. I want a pool in the back yard. I also want a big space for my three cars. As of now, I am living with my old house that I inherited from my mom. The space is not enough for us so I want a new home. How do I begin the process of buying a home here in Charlotte, NC? What is the process in buying a home? What should be the first step?
