Buying a Property at Auction in Belgium: Benefits, Pitfalls and the Full Process

Buying a property at auction: opportunity or risk?

Buying a property at auction sounds exciting: lower prices, fast completion, sometimes unique opportunities. Yet many prospective buyers hesitate - is it too risky? What should you watch out for? And who actually organises these auctions?

In 2025, the auction route genuinely offers advantages for those willing to prepare carefully and run the numbers. This guide explains clearly how auctions work in Belgium, where the pitfalls lie, and when auctions are truly worth considering.

Types of auction in Belgium: two main categories

In Belgium, there are two types of property auction:​

1. Voluntary public sale (notarial auctions)

These are auctions where a willing seller - through their notary - chooses to put their property up for public sale. Why?

• Faster sale
• Broader reach of potential buyers
• Sometimes a higher price thanks to competition​

Procedure:​

• The notary publishes an announcement with details (location, date, starting price)
• One or more viewing days in advance (usually)
• Auction day: bidders compete openly against each other
• The highest bidder wins (binding offer)
• Payment and transfer of ownership handled by the notary

The starting price is based on a valuation; it can often be set low to generate interest.​

2. Forced sale by execution

These are auctions where a debtor loses their property because they cannot repay their debts. Usually a bank initiates the process based on its mortgage rights.​

Why are these riskier?

• The property is sold as-is, without any guarantees
• A tenant may still be occupying the property; you may have to wait before taking possession
• Legal complications can arise (easements, historic charges)
• Far less viewing time than with voluntary auctions

That said, prices are on average lower than the regular market, especially when the debtor wants to avoid racking up excessive costs.​

Advantages of buying a property at auction

1. Potentially lower price

At forced sales, the price is sometimes 20-40% below market value because:

• The debtor has no negotiating power
• The seller wants to wrap things up quickly (to limit costs)
• Competition among bidders can be fierce, but it starts low​

For voluntary auctions the advantage is smaller; you are simply competing with other interested parties at a public session.​

2. A faster process

• No lengthy negotiations
• No - or very limited - suspensive conditions
• Payment and transfer within weeks​

3. Greater certainty for the seller

For the owner - in the case of a voluntary auction - the advantage is that on auction day it is immediately clear who is buying and at what price: no more risk of the deal falling through.​

4. Transparency

The auction procedure is standardised and legally clear; everyone plays by the same rules.​

Risks and pitfalls: what to watch out for

1. Limited or no viewing

Especially at forced sales, prospective buyers may have little or no access to the interior of the property. You are effectively buying "blind", which could mean:

• Serious hidden defects (rotten window frames, damp damage, outdated systems)
• A worse state of maintenance than you expected
• High renovation costs that were not in your budget​

What you can do:

• Ask the notary for exterior photos or a short video
• Hire a surveyor or structural expert who can inspect the property from outside
• Ask neighbours about the condition of the property​

2. No suspensive conditions (as a rule)

At auctions, the bid is immediately binding. No reservation for:

• Mortgage financing (you must pay, even if your loan falls through)
• Soil certificate (contamination)
• Town-planning regularisation

This makes auctions high-risk: you are buying almost entirely "as-is".​

Solution:

• Make sure BEFOREHAND that your financing is in place (no reservation needed)
• Have all required certificates checked in advance​

3. A tenant may remain in place

At forced sales, the debtor may still have tenants. Those tenants have rights, and you cannot simply evict them.​

• You inherit the tenancy arrangements of the previous owner
• Maintenance obligations continue to apply
• Any rent arrears may become your problem​

Make sure you have a clear picture:

• Ask the notary which lease agreements are in place
• What is the profile of the tenants? Do they pay on time?
• How much time is left on the leases?

4. No standard guarantees or protections

In a normal sale, the seller provides certain guarantees (no major defects, agreed condition of the property). At auctions, these disappear almost entirely.​

• The previous owner is under no obligation to deal with major defects
• No guarantee on the durability of the roof, windows or installations
• You are entirely dependent on your own inspection beforehand​

5. Legal complications

Forced sales can come with legal baggage:

• Easements (for example, your access path runs across someone else's land)
• Municipal enforcement notices (unsafe, derelict)
• Tax charges on the property (unpaid local taxes, water bills)
• These charges pass to you as the new owner​

Practical steps: how to bid at an auction

Step 1: Find the auction

Notarial and forced-sale auctions are published on:

• Notary websites (notaire.be, local offices)
• Vastgoedveiling.nl, openbareverkoop.nl, bog-auctions.com
• Local newspapers (Saturday supplements)
• Bailiff websites​

Step 2: Gather information

• Read the auction listing carefully (date, location, starting price, special features)
• Check what viewing slots are available​
• Ask the notary for all relevant documents: energy performance certificate (EPC), asbestos certificate, town-planning information, lease agreements

Step 3: Inspect or arrange an inspection

• Visit the property yourself if possible (external inspection)
• Ask the notary for interior photos or documents about the property's condition
• Consider hiring an independent surveyor​

Step 4: Arrange your financing

• This is crucial: are you CERTAIN you have your credit in place? Because at an auction you can no longer say "my loan was refused"​
• Go to your bank or a mortgage broker and ask for a letter of credit or written commitment - not just an indicative figure​
• Make sure you already have the deposit amount available (the notary usually requires this upfront)​

Step 5: Bid

• On auction day, you attend the notary's office (or bid online for certain auctions)
• The notary opens the bidding at the starting price
• Bidders raise the price step by step (often in increments of €1,000 or €5,000, depending on the notary)
• Your most recent bid is binding​

Step 6: Pay

• You usually have to pay within a set period - for example 6 weeks​
• Payment is made to the notary, who then arranges the transfer of ownership
• If you fail to pay, the notary can instruct a bailiff to pursue you​

Is it worth it? How to work out the numbers

Buying a property at auction makes sense if:

• Your financing is already fully arranged (no risk of refusal)
• You have a budget for unexpected renovations (keep a buffer!)
• The starting price is realistically low relative to market value​
• You want speed and want to avoid lengthy negotiations​

Not worth it if:

• Your financing is not yet guaranteed
• You have no buffer for surprises
• You are afraid of bidding too high on pure emotion​

A realistic estimate:

• Auction starting price: €150,000
• You expect to go up to: €180,000
• Subsequent renovation costs: +€20,000
• Total: €200,000 vs. €220,000 for an equivalent property on the regular market
• Advantage: €20,000, minus the increased risk​

Warning: watch out for auction fever

Many buyers get caught up in "auction fever" and bid higher than is sensible, simply because there is competition. That is why:

• Decide BEFOREHAND on your absolute maximum price
• Do not forget to factor in future renovation costs
• If you go over your limit, ask yourself: why?
• Am I panicking, or is this realistic?

Conclusion: auctions can be smart - with proper preparation

Buying a property at auction in Belgium in 2025 offers real advantages - speed, transparency, potentially lower prices - but it demands thorough preparation:

• Your financing must already be in place
• Inspecting the property is essential
• Your budget must include an extra buffer for surprises
• A legal check by the notary is not optional

With those precautions in place, buying at auction can be a smart move in your property-buying strategy.

Before you register for an auction, make sure your financing is definitively confirmed. Use a loan simulator to establish your budget, and request a free valuation of the property if you are unsure about its market value.

That way, buying at auction becomes not a gamble, but a well-considered opportunity.
