Actually listing agent does have a fiduciary responsibility and good ones know and respect that. Otherwise they get sued.
You may be incurring more risks with a bad buyers agent just like you can avoid risks with a good one.
Like I said this isnt rocket science. I’m sure that any of you who spent a few years of their life doing this and closing several dozen transactions would gain the experience to be very good at this. Someone doing anything in this world for the first time is unlikely to do it well. Its really that simple. The first time you try to rollerskate you usually fall on your butt and dust yourself off. In a real estate transaction it can be very costly to fall on your butt and even more costly to dust yourself off. Thats all. It doesnt matter to me what you do and I hope it goes well for you whatever you decide.
