Understanding the data
Valuation, minimum bid and award: three different figures
Understand auction price labels and compare properties without confusing a valuation with a market price.

A valuation is a published reference
The valuation shown on a listing comes from the information available to this service. It is not a market estimate we have calculated today or a promise of what you could recover by selling the property.
When comparing listings, check whether you are looking at a valuation, a minimum bid or an award result. The label matters as much as the number.
The minimum bid is not a purchase price
The minimum bid is the amount identified as such in the auction data. It does not mean you can acquire the property for that amount. Participation rules and the result depend on the notice and proceeding.
If no minimum bid is published, a card may show the valuation with its own label. In the comparator, the bid appears as “No minimum bid” or “Not available”, and the difference and price per square metre appear as “Not available”.
A percentage against valuation does not prove a saving
If a listing shows a €100,000 minimum bid and a €150,000 valuation, the mathematical difference is about −33.3%. This comparison relates only those two figures.
It does not include charges, costs, condition, local liquidity or the amount ultimately awarded. That is why the site calls the column “Difference between minimum bid and value”, rather than presenting it as a return. Our guide to charges and occupied properties explains what to review before bidding.
Build a consistent comparison
The free comparator uses the same definitions in every column. You can view up to four homes, their area and the minimum bid per square metre when both figures exist.
That ratio is not a sale price per square metre either. It is a way to organise your notes and identify which listings need a closer review. Export the CSV if you need to extend the analysis outside the site.
Check the result in the official source
For completed BOE auctions, the listing shows the highest bid or that there were no bids, as published by the BOE. The highest bid is not the award price: the award may not be approved or the asset may be awarded to the creditor. The site does not infer the result from the minimum bid or from an assumption.
Keeping published data separate from recorded changes lets you review an auction’s history without confusing it with an open opportunity. Completed auctions are collected in the history.
