Some agents treat it as a tactic. We don't, because it rarely buys real leverage and it invites risk. Once the contractual contingency period lapses, the seller or listing agent can issue a Notice to Perform. That starts a short clock, often around 48 hours depending on your contract, for the buyer to respond before the seller can move to cancel. Sitting on the deadline invites exactly that, so the tactic can backfire. Releasing contingencies proactively does the opposite. You signal good faith and show the other side you're a reasonable party, which matters if you later need the seller's cooperation on a repair or a credit. When a buyer keeps pushing removal to the last possible day, the useful question is why. More often than not you're looking at cold feet rather than strategy, and the cold feet are the real thing to address. A genuinely uncertain buyer needs a direct conversation, and running out the clock just papers over the doubt. So no, we wouldn't lean on last-day removal as a negotiating move.
