Being a referral-only agent?

[John Guy]

Hello!

I'm 26 years old and live in southern Maine. I have been managing STR and LT rental properties for about 4 years and have a portfolio of about 67 properties. It is my W2. This summer, I decided taking the 55hr sales agent course would be the next step to continue learning about the ins-and-outs of real estate and be able to take advantage of the leads that come across my desk.

But I am at a cross-roads here. The brokerage offers both a sales agent company and a referral company, and I can hang my license at either one. With the crazy rentals workload, I'm worried I won't be able to be successful in sales while maintaining the quality of care I strive for with the rentals. I have a great network in southern Maine for both buyers and sellers. 

My question is this: Does anyone have experience with referral agents, and if so - what advice/suggestions do you have to make it a successful route?
