Why there is no clean universal average
Auction outcomes vary by asset type, location, pricing strategy, seller motivation, catalogue quality, market conditions, legal complexity, and buyer competition. A tractable flat in a strong rental area behaves differently from awkward land, a mixed-use asset, or a structurally messy house.
Because of that, anyone quoting one simple uplift percentage as a universal answer is usually offering a story, not a dependable underwriting tool.
What actually happens in practice
Some lots sell close to guide because the guide was already realistic and demand was measured. Some sell much higher because the guide was promotional, the lot was easy to understand, or several buyers wanted the same thing. Some fail to sell because reserve was not met or the risk outweighed the upside.
That spread is normal. The useful lesson is not to guess the final price from the guide alone.
Why guide price still matters
Guide price is still useful as a screening field. It helps you sort, compare, and decide which lots deserve your time. It just should not be confused with the number at which the deal will definitely clear.
That is why DistressScope keeps guide price visible on live opportunities, but the buyer still needs to do their own pricing work around the lot.
A safer way to plan your bidding
Treat guide price as a signal and then build your own maximum bid from the full cost stack, the condition, the legal position, and your exit plan. If the lot runs above that number, it was not the right buy for you at that price.
This is one of the simplest disciplines that keeps auction buying from turning into emotional bidding.
