Why Identical Hammer Prices Can Cost Very Different Amounts

How to Read an Auction's Fee Structure Before You Bid
Every auction publishes its fee structure before bidding opens — most bidders just never read it. Here's exactly where to look, the four numbers that matter, and a worked comparison of two very different terms sheets at the same hammer price.
