Just to chime in with my own real estate agent story. I'm in the process of selling my house (FSBO, no realtors). It's in a "hot" neighborhood, best elementary school in the city, been there for 9 years and never seen a house sit for longer than a month on the market in this neighborhood.
Couple shows up to the house one day, saw the For Sale signs up the street, ask if they can take a look around, we give them a tour. They said "oh we love it, we're definitely interested, let's look at a couple more but we'll probably be back in touch with you." Never once did they mention anything about them having a realtor.
Next day I get a call from a realtor who is representing this couple and she asks if I'll cut her in 3% commission on my house. I said no, I wasn't willing to give up any % to a buyer's agent at this time. She says "but they have a contract with me, I have to represent them and this is how I make my money. If you don't give me a commission % then I don't get paid. So you're also saying that you're not willing to entertain a potential buyer?". I said "I'm well aware of how commission works. If you have a contract with the buyer that prevents them from buying from me directly, then you're preventing them from the potential buy, not me. If you want 3% or whatever amount for your cut, talk to your buyer and tell them to cover it".
She calls me back later and says "ok they agreed to cover my fees out of their own pocket, and they want to make an offer". I said ok. They submit the offer at 10 pm on Thursday, with an offer expiration date of 3 pm Friday. So I get 17 hours to respond to an offer, huh, that's how we're going to play this? I call their realtor the next morning (Friday) and tell her "I would like to counter but I simply don't have time to draft a proper counter in this short amount of time so I'm verbally rejecting the offer. You're free to submit another offer, but it needs to be closer to X price, with X closing date, X closing cost split and you need to give me at least 2 full business days to respond to it".
That night (still Friday) I get a second offer at 10 pm again, that expires at noon on Monday. ? I honestly wanted to tell this realtor and this couple to go take a hike with their BS, but I didn't. Ended up drafting a proper counteroffer over that weekend and submitted it to her by noon Monday, and it got accepted the next day. Home inspection was done, appraisal was done, everything done. We're on track to meet and do the closing in 5 days. And their realtor still has not seen the house at all. It boggles my mind why this couple would agree to buy the house, plus pay whatever their realtor is asking, when they are the ones that found the house, the were shown the house by us (not their realtor), and the realtor herself has not even laid eyes on the house.
