Have been corresponding with two Realtors via phone and online. I picked the Agent I like best and wanted to see a house tomorrow. (Our house is under contract, and it’s time to buy a new one.) Told her we wanted to make an offer on a listing she sent us. She acknowledged my email, said she was busy and would call me back. It’s been hours and I haven’t heard from her. I’ve emailed her 3 more times. No response. She’s the one who emailed the listing to me.Would it be improper to switch Realtors mid-stream and have the other one show it to me before it’s sold? We would like to buy it this week, like tomorrow! I haven’t met either Realtor in person yet. Am I obligated to her in any way? ThanksEdited to add: They are in a city several hours away from where we live.
