Why the asking price is not your cash plan.
The asking price is a starting point for negotiation, not a list of everything you will pay. Setting aside only a deposit and “a little extra” can leave you discovering later that taxes, deed fees and borrowing costs need more room than expected.
That difference becomes real when an apartment or townhouse in Antwerp catches your eye. You want to know not only whether you can buy it, but what will remain for an inspection, moving or initial work. A buffer belongs in your decision from the start, not just on the final bill.
Consider two questions together: what does the home appear to be worth, and what will the purchase cost altogether? A lower offer helps with both, but does not remove the extra costs.
What usually goes into the total?
Think in layers, rather than one surprise bill. You can then see which amounts are fixed, which move with the purchase price and which you still need to investigate.
- Price. The amount you agree with the seller. It need not match the asking price.
- Property transfer tax. The tax on the purchase. These simplified Flemish examples compare 2% and 12%; your circumstances determine whether that comparison applies to you.
- Notary. Professional and deed fees. Use the official calculators to explore them further.
- Mortgage. The costs of your borrowing and the associated deed or security. Your bank and notary can explain your situation.
- Buffer. Room for a valuation, inspection, moving and minor work in the first few months.
The layers are not equally large. At a higher tax rate, property transfer tax can make a substantial difference. Your buffer is a personal choice: decide what you want to cover without immediately borrowing again.

Change the purchase price and compare the rates. Adjust the example notary fees, mortgage costs and buffer, or uncheck them to see their effect. Save your scenario in this browser to return to it later. Unchecking a cost removes it from the example, not from an actual purchase.
2% or 12%: where buyers get caught out.
A reduced rate can seem like a detail in the small print until you see the difference in euros. Eligibility depends on factors including your property ownership, the form of purchase and your registration at the address. A blog can offer direction, but not legal certainty.
Unsure? Calculate both scenarios. If your plan only seems affordable at the lower rate, discuss the conditions early. Do not wait until you sign the purchase agreement.
This short check helps you recognise the main conditions. Ask your notary to confirm how they apply to each buyer.
Another property, several buyers or an unusual purchase? Exceptions may apply. This check does not determine your rate.

Example: €350,000 in Antwerp.
Take a round purchase price of €350,000. At 2%, the example gives €7,000 in property transfer tax. At 12%, that is €42,000 before any other costs. The difference alone is €35,000.
| Cost layer | At 2% | At 12% |
|---|---|---|
| Purchase price | €350,000 | €350,000 |
| Property transfer tax | €7,000 | €42,000 |
| Other example costs* | €18,000 | €18,000 |
| Total example budget | €375,000 | €410,000 |
* €4,500 for notary and deed fees, €3,500 for mortgage costs and a €10,000 buffer. These are not calculated professional fees. Reductions, a different taxable base and special regimes are not included.
The point is visibility. A home can look affordable when you only consider the asking price. Adding the extra costs and your preferred buffer may change your personal ceiling. Bring that insight to your offer, rather than waiting for your bank appointment.
What Neighbour does here—and its limits.
This article puts a cost picture alongside your thinking about an offer. The Antwerp examples help you recognise the amounts; links to official sources help you calculate further.
Neighbour does not replace a notary or bank adviser. The example does not know your loan or check your documents. Discuss purchase and borrowing costs with your notary. Sources: notaris.be

A few more questions.
Is the Immoweb asking price my total cost?
No. Property transfer tax, notary and borrowing costs, and a buffer sit alongside the agreed purchase price. Your loan also affects how much of your own money you need.
When can I use the 2% rate?
Only if you meet the legal conditions. Check the official source beside the checklist and ask your notary to confirm how it applies to you.
Does this page replace the notary’s calculator?
No. This article shows how the costs fit together. Use the calculators at notaris.be for a more detailed calculation.
