You were told that dual agency is legal in Oregon, and if you feel comfortable, you can proceed with the listing agent...........if not, then find a new agent (which apparently you are doing).
It's a pleasure (and rare) to read answers on a thread that don't all shout out: "Call me - call me" with a long sign off listing every phone and fax number they have, and every award they ever received. :)
Kudos and thumbs ups to everyone here!
That listing realtor worked my offer against her own and was working for own self interests. Realty business is still a crooked business, and it's not very well regulated. So, be careful, and don't take anybody's word for anything, and verify everything!
Any agent that works a dual agency transaction from both sides that says they don't feel a bit uncomfortable in this environment isn't being completely honest!
Good luck in your home search!
