How do I become an Interior Designer as a Realtor?

[Fallon Morris]

Hello, 

I currently have my real estate license and I'm also about to be done with a fix and flip I've been working on. Throughout the process of this fix and flip I've realized I really enjoy doing the Interior Design part of real estate, not just the decorating part. I have been looking into Interior Design and I've noticed you can go to college and get a degree for it, and they also have an online certificate program. I would still keep my license as a Realtor, but I was wondering if anyone knew the best route to take? I'm not sure if I would HAVE to be "certified" or have a degree for it but I'm definitely trying to avoid the years of college if at all possible. Does anyone know how I could start or get my foot in the door as an entry-level designer or design assistant with no degree/little experience? Any and all advice is appreciated, thank you!
