Specializing in one type of property to sell

[Chris Lynch]

I am a licensed agent in Rhode Island. I have been working in the rental business ( Finding renters for landlords) Now I plan to start selling property's and obtaining listings. It seems like many agents will take anything that comes there way. 

I would like to specialize in multifamily property. Make that the main focus of my business. Mainly because I enjoy investments and I can understand investors because I have the mindset of an investor. I would also love helping people achieve their financial goals through Real estate.

A couple agents have told me this is a bad business plan and to sell anything and everything you can. I do not think this is the right approach. My goal is to bring value to people and In my mind one way to do that is to specialize and become an expert in a particular niche. I would love feedback.
