Buying a house soon and need some advice on what commission you had with your realtor

Hey everyone, so like the title says, I'm hoping to get a place of my own soon in the Lansing/EL/Okemos/Haslett area, and the main thing I'm trying to figure out is what the typical % (or $ if flat rate) commission was that you had when buying with your buyers agent? Price for the home I'll be shopping around for is around 150-250k if that information is needed. I have a realtor that I really liked, but I just want to make sure I have the info I need before signing to be in a contract with them for the next 3 months
