Wanting to Build a Custom Home

Hello Reddit! My husband and I are strongly considering building our own home— lately I’ve made my whole world about putting together a vision, and I made a REALLY rough floor plan.

  1. How do I realistically get this process started? Should I acquire land first then builder after? Or am I missing anything critical?

  2. Could I show my INCREDIBLY rough floor plan mock up I drew and get opinions on whether or not this is even a realistic option

Thanks all!
