Can My Agent Still Get a Commission If I Saw It At Open House?

[Lee Rutty]

Apologies if this is answered somewhere but if so I can't find it.

If I view a property with the listing agent, does that prevent my agent getting a commission on the sale?

I'm pretty new to this so I want to have an agent represent me in negotiations and the offer. There's an agent we are talking to and want to start a relationship with. When we told her that we're interested in a property that we had viewed (at an open house), she stated that if we'd already seen it with the listing agent she wouldn't get a commission if we did an offer through her. It's probably the property we're most interested in but I don't want to deal directly with the listing agent.

She is the expert and why would she cut herself out of a deal? But it just doesn't seem logical to me, so looking for advice.

I'm in Maine if state laws differ.

Thanks!
