Also for buyer’s agent commission you need to understand why buyers wrap it into the purchase price.
Instead of offering a rate, just tell buyers to include it in their offer, and evaluate each offer on its own merits.
HOWEVER - keep in mind almost all of the recently sold comps you are looking at include 2.5-3% buyers agent commission. So if you want to be stubborn about paying it that’s fine, but expect buyers to reduce their offers compared to comps by a similar amount. They’re not stupid.
