Marking too early costs you other interested buyers if the first one falls through; marking too late risks two buyers showing up for the same item. The right moment is a specific point in the conversation, not a fixed time delay.
The rule: mark pending at genuine commitment, not at interest
Reading the conversation
| Buyer's message | Genuine commitment? | Action |
|---|---|---|
| "Is this still available?" | No — this is initial interest, nothing scheduled | Keep listed as available |
| "I might come by this weekend" | No — no specific time, non-binding | Keep listed as available |
| "I can be there tomorrow at 5pm, I'll take it" | Yes — specific time and clear intent to buy | Mark pending now |
| "Can you hold it, I'm not sure when I can come" | No — a hold request without a scheduled time isn't a commitment | Politely decline to hold indefinitely; keep available or ask for a specific window |
Handling other interested buyers once it's pending
A polite, honest response to a second interested buyer once an item is pending — "I have someone scheduled for pickup, I'll let you know right away if that falls through" — keeps that buyer as a warm backup without overcommitting the item to two people. This is exactly the situation the no-shows article's "message other recent inquirers" step is built for.
