Working with Realtors

[Ashlee Andrews]

Hello community! New investor here. I am looking for my first investment property and I have seen a few with a realtor who happens to be a good friend of mine. I reached out to another realtor because she owns 20 rental properties and her knowledge and experience is what I need especially at the beginning. She agreed to help me along the way and said she will set up properties to walk through. While I was waiting on her to respond to my email (2 weeks ago), my realtor/friend contacted me about a duplex, set up a showing and I put in an offer. I told the investor/realtor about my offer and she became offended and stopped responding to me. I was open with her from the start that I have seen 3 properties already so she knew I was working with someone. My question is; is it frowned upon to work with more than one realtor or is this normal behavior in the real estate world?
