Multiple Realtors - offensive?

[Ashley Shearer]

Hello - my husband and I are closing on our first house this Friday (duplex, house hacking). We plan to buy many more houses over the years and build this business. We're using a realtor who has been very helpful and has taught us a lot throughout this process. The only problem is I feel like we don't "fit" with him. He is not as aggressive as we would like, and he's also a little disorganized. I keep thinking, "we are building a business, we need a solid team" and I just feel like he is not the right fit for our team. 

My question is - how do you quit your realtor when he's already expecting us to use him for the next house? We would still like to keep in contact with him for potential future deals as a part of our network, but would be more interested in using another realtor for the next one. Wouldn't that offend him?

Another question - many people on here talk about using multiple realtors or having realtor contacts who can offer deals before they even go to market. How do people do this without offending their other/first realtor? I'm not a realtor, but I'd think if my clients went with someone else for another deal, I'd be offended. Then we would worry that our realtor might not be trying to get us the best deal. 

Would appreciate any advice from the other side!
