I've used buyers agents (1 traditional, 1 Redfin) when I've bought homes since they are being paid from the Seller's Fees and in most states I believe they are legally bound to act in your best interest. I've had a new construction seller try to convince me to not get an agent and would give a discount instead but felt that the risk wasn't worth it especially since most buyers agents I've engaged with have been open…
Anything else and they have too much of an incentive to produce an inspection report that will result in a quickly closed sale.
