Using multiple buying Real Estate agents in one City

[Bonifacio Capuyan]

Hi All, I am a super newbie to the forums. I currently own my primary residence and have two SFRs in the Midwest both are rehabs (one is rented and one is in the process of rehab). 

My question is, what is the etiquette of using multiple real estate agents in one town? Is it best to stick with one? Or can I use as many as I want. The reason I'm asking is because I don't want to ruffle any feathers or upset or hurt anyone's feelings. Any advice?
