Difference between the sale price and the open market value of a home

The difference between the sale price and the open market value of a home comes up as soon as a notary, a banker or the tax authorities get involved. Both terms describe an amount in euros, but they answer different questions. One describes what your property is worth on the market. The other describes what a buyer actually paid. Understanding that gap saves you from an unpleasant tax surprise and from a starting price set on the wrong basis.

What open market value means

The open market value is the amount a property could reasonably fetch if it were offered for sale on the open market, between a seller and a buyer who are both properly informed, with no particular connection between them and no pressure of time. It is a theoretical value, established on a specific date.

It serves as the reference in a series of situations where no sale takes place, or at least not at market price:

• an inheritance, where the heirs have to declare the value of the property on the date of death;
• a gift of property;
• a division of assets after a divorce or a separation;
• the granting of a mortgage loan, where the bank wants to know the value of its security;
• an expropriation or a dispute between parties.

An open market value is never a figure set in stone. Two experts who visit the same house often arrive at amounts that sit within a few per cent of each other. What matters is the method followed: recent comparable sales in the same neighbourhood, the actual condition of the property, the habitable surface area, the PEB energy performance certificate and the direction of the local market.

What the sale price means

The sale price is far more concrete. It is the amount you and the buyer have agreed on, written down in black and white in the preliminary sales agreement (compromis) and then repeated in the notarial deed. It is no longer an estimate, it is a fact.

That amount carries direct consequences. The registration duties payable by the buyer are in principle calculated on this price. Your estate agent's fees, the settlement with the buyer and the balance that comes to you once your loan has been repaid all follow from it as well.

Be careful not to confuse the sale price with the asking price. The asking price is the one you display in the listing. The sale price is the one that remains after negotiation. Between the two there are sometimes several thousand euros and a few months on the market. An over-ambitious asking price stretches the timeline, wears out the listing and often ends up producing a lower sale price than a realistic launch would have done from the start.

Why the two amounts do not match

In a calm market and with a carefully prepared launch, the sale price comes close to the open market value. In practice, several factors widen the gap.

• Urgency. A seller who has to close within two months accepts an offer below the estimated value more readily.
• The private circle. A sale to a child, a sibling or a tenant is rarely negotiated at market price.
• Competition between candidates. Several simultaneous offers can push the price above the estimate.
• Time elapsed. An estimate carries a date. Between the report and the signature, the market in your municipality may have moved.
• What the viewings reveal. Damp, tired window frames, a disappointing PEB rating: the buyer takes these into account in the offer.

One factor stays genuinely in your hands: the way the sale is run. The visibility of the listing, the quality of the photographs and the handling of the negotiation all weigh on the final amount. Comparing several agencies before you sign a mandate shows you not only different fees, but also different pricing strategies. You can compare up to three estate agents active in your municipality free of charge and weigh up their arguments before choosing.

When open market value becomes a tax issue

As long as you sell normally to a third party, the question stays theoretical: the agreed price is what counts. The open market value becomes a real issue as soon as there is no sale at market price.

In an inheritance, the heirs declare the value of the property. In a gift, the declared value serves as the basis for calculating the duties. Depending on the region where the home is located, it is the regional tax authority or the FPS Finance that checks that declaration.

Both mistakes cost money. A declared value that is too low can be challenged: the authorities then claim additional duties, generally increased by a penalty. A declared value that is too high makes you pay duties on an amount the property will never reach. That is why many families have a written valuation drawn up at the reference date and keep it in the file. Your notary will tell you which form of valuation is accepted in your case, because the procedures differ from one region to another.

How to establish both amounts for your property

The process works in layers, from the broadest to the most precise.

1. Start with a range. A free online valuation positions your home against recent comparable sales. It is a starting point, not a verdict.
2. Have someone come and look. Only a visit takes account of the actual condition, the orientation, the noise, the garden and the work that has been carried out.
3. Set several opinions side by side. Two or three local agents who know the real sales in your neighbourhood are worth more than a single isolated figure.
4. Put it in writing for tax purposes. For an inheritance or a gift, a reasoned expert report or your notary's involvement gives you a defensible basis.

One reflex to avoid: choosing the agent who announces the highest amount. An overvalued starting price is almost always corrected downwards, after weeks have been lost. Look instead at how each agent justifies the figure, with which comparable sales and within what timeframe. Receiving proposals from several agents is free and without obligation, and makes those differences visible straight away.

Frequently asked questions

Is the open market value the same thing as the market value?

In everyday practice, yes. The open market value is the price a home would reach on the open market, between an independent and well-informed buyer and seller. It is simply the term used by notaries, valuers and the tax authorities.

Can the sale price be lower than the open market value?

Yes, and it happens regularly: an urgent sale, a sale to a family member, a property sold as it stands or a local market with little activity. The agreed price remains valid between the parties. If the property goes well below its value to the benefit of a relative, the tax authorities may nevertheless reclassify the transaction. Have your notary check this point before you sign.

Who determines the open market value of a home?

There is no single body. An estate agent estimates it with a sale in mind, a property valuer sets it out in a reasoned report, a bank has it established for a loan, and the tax authorities form their own opinion in the event of an inheritance or a gift. The ingredients are the same, the purpose differs.

Is the open market value linked to the cadastral income?

No. The cadastral income (revenu cadastral) is a theoretical net rental income used to calculate the property tax (precompte immobilier). It does not reflect the current market value of your home and cannot therefore serve as a valuation for a sale.

What to remember

The open market value answers the question "what is this property worth", the sale price answers the question "what did it bring in". The first is an estimate on a given date, useful above all when no actual sale sets the amount. The second is the result of a negotiation, influenced by your timeline, by the condition of the property and by the way the sale was run. One last point: tax rules and valuation procedures differ from region to region and change over time. Always check your own situation with your notary and, for the sales side, with estate agents active in your municipality.
