Auction budget worksheet
Write down your own auction ceiling and an optional buffer before bidding. See the arithmetic clearly and connect it to your wider purchase costs.
This worksheet subtracts a percentage buffer from a ceiling you choose. It does not assess affordability, suggest a bid or value the property.
Auction walk-away
Decide it before auction day, tell whoever comes with you, and don't move it on the day.
Want a licensed buyers agent on this?
They can inspect, appraise, negotiate and bid for you — the things a research tool can't do.
