HOW THE MAX BID WORKS
Start from the after-repair value and apply your discount — that is the ceiling. Then subtract everything the deal will cost you before it pays: rehab plus a contingency, closing and title, holding costs while you own it, and the minimum profit that makes the risk worth it. What is left is the most you can bid. Write it down before the auction starts and never bid a dollar past it — the number does not change because the room got excited.
