Yes, technically, you can be. Some Realtors try to be part time, but it’s difficult to do so, both for yourself financially and in what you are able to offer your clients. I checked my profit and loss sheet last year, and I spent $5,000 on my license, fees, MLS access, etc. If you only sell a few homes each year, have to save 1/3 of that for taxes, AND spend $5,000 just to maintain your Realtor status, it’s probably not worth it to you.
When I started out in real estate, it was more for a hobby than anything else and I thought I’d be part time. As I became better acquainted with what it took to do real estate, I realized that in order to best serve my clients when asking them to trust me with their most expensive purchase, I needed to be as active and informed about the market as humanly possible. This meant being a full time Realtor. I made that decision early on and haven’t looked back since.
While I wouldn’t recommend being a part time Realtor, if you ever have a question and maybe think being a real estate agent is for you, I am very willing to answer any questions you might have and help you on your way.
