Why are agent's turning me away?

[Account Closed]

I just closed on a SFH rental in an area I'm familiar with. I closed the deal myself. For more propeties I've contacted three agents from different Brokerages and all three have given me the "thanks but no thanks" routine. I am a very self-aware person and I really don't think I have come on hard in any of the inquiries. In a nutshell, they contact me after my initial inquiry and they're all excited, asking me what I'm looking for and at what price. And when I tell them I am looking for a 3br 2ba rental home, they boogey. I've bought and sold two homes on my own without the use of an agent. This is the first time I'll be trying to use one. I guess I'm experiencing the sentiment I often see -- that agents are averse to investors. Any thoughts?
