What should you do if you sell your property at a loss?

Updated in July 2026.

Are you selling your house or apartment for less than you originally paid for it? Wondering whether this financial loss could at least provide some form of tax relief? More importantly, how will you repay the outstanding balance of your mortgage if the sale price is not enough to cover the remaining loan?

A property capital loss is a situation many homeowners fear, particularly in areas where property prices have stabilised or declined after several years of growth. Contrary to what many people believe, a capital loss on residential property in France provides no tax relief whatsoever. It is neither deductible nor can it be offset against future capital gains. However, it can have significant financial consequences, especially if there is still a mortgage outstanding.

This article explains what a property capital loss is, the most common reasons why it occurs, how it is treated under French tax rules in 2026, its impact on outstanding mortgage repayments, and the practical strategies available to anticipate, reduce or even avoid it.

Before rushing into a sale—or deciding not to sell for fear of losing money—it is essential to understand your property's true market value and the options available to you. Start with an online property valuation to obtain an initial estimate, then seek professional advice by contacting your local Capifrance property consultant, who can provide a detailed analysis of your local market and recommend the most appropriate solution for your situation.

In summary 

• A property capital loss occurs when the resale price of a property is lower than its purchase price, after taking into account acquisition costs and eligible renovation work.
• In France, a capital loss realised by a private individual on residential property cannot be deducted from taxable income or offset against future capital gains, except in extremely rare circumstances.
• The main practical consequence concerns any outstanding mortgage. If the sale price does not fully repay the remaining loan balance, the seller must personally finance the shortfall.
• The most common causes include purchasing at the peak of the market, falling local property prices, a poor EPC rating, unexpected renovation costs or the need to sell quickly.
• A realistic professional valuation, combined with carefully targeted improvements before listing the property, can often reduce—or even avoid—the resulting loss.
• Several solutions are available when the outstanding mortgage exceeds the expected sale price, including renegotiating the loan with the lender, temporarily renting out the property or seeking support from an experienced property professional.

What is a property capital loss?

Definition and how it is calculated

A property capital loss is simply the opposite of a capital gain.

It represents the negative difference between the property's sale price and its acquisition cost, the latter including purchase costs (such as notary fees and, where applicable, estate agency fees) as well as, under certain conditions, the cost of eligible renovation works.

The calculation is straightforward:

Net selling price minus the adjusted purchase price (including eligible acquisition costs and qualifying works).

• If the result is negative, a capital loss has been made.
• If the result is positive, it is a capital gain, which may be subject to 19% capital gains tax plus 17.2% social contributions, unless an exemption applies (for example, the sale of a main residence or ownership for the qualifying exemption period).

It is important to remember that capital gains on a main residence are already fully exempt from tax in France.

As a result, the issue of a capital loss mainly arises in two situations:

• selling your main residence for less than you paid for it (with no tax implications but a direct financial loss);
• selling a second home or rental investment below its purchase price (again with no tax due, but equally with no possibility of offsetting the loss against other taxable gains).

Why are property capital losses being discussed more frequently in 2026?

After several years of sustained growth across many French cities and coastal areas, the property market has undergone a more noticeable adjustment since 2023–2024, followed by a gradual stabilisation during 2025–2026, depending on the region.

Homeowners who purchased at the height of the market—particularly during 2021 and 2022—are now the most exposed to the risk of selling at a loss.

This risk is especially significant for:

• properties in ageing apartment buildings requiring major energy-efficiency renovations;
• rural or suburban markets that experienced only a temporary surge in demand following the Covid-19 pandemic;
• properties with an EPC rating of F or G, which have become less attractive because of increasingly strict rental restrictions and buyers' concerns about future renovation costs.

The most common causes of a capital loss when selling

Buying at the peak of the property cycle

This is by far the most common structural cause.

A property purchased at a high price during a period of exceptionally low interest rates and strong buyer demand may naturally lose value when the market corrects.

This does not necessarily mean that there is anything wrong with the property itself—it is simply the effect of the property cycle, which is often impossible to predict at the time of purchase.

A declining or stagnant local property market

Not every property market behaves in the same way.

A town that has lost major employers, a rural municipality facing population decline or a neighbourhood whose attractiveness has deteriorated because of shop closures, ageing infrastructure or increasing security concerns may experience price falls that are considerably greater than the national average.

This is why a detailed analysis of the local market—not national statistics—is essential when assessing the risk of a capital loss.

Poor location, unexpected renovation work or a weak EPC rating

A property located on the ground floor, facing north, overlooking a busy road or requiring extensive renovation—such as roof replacement, façade repairs or electrical upgrades—will generally sell at a significant discount compared with similar properties in more favourable conditions.

Likewise, an E, F or G EPC rating can now reduce a property's value by 10% to 20%, depending on the local market, as buyers increasingly factor in both future energy-efficiency renovation costs and the progressive restrictions on renting out poorly performing homes.

A forced or urgent sale

A compulsory job relocation, separation, inheritance settlement or financial difficulties may force a homeowner to sell quickly without waiting for better market conditions or having sufficient time to negotiate.

This pressure almost always leads to an additional discount, as buyers generally recognise the urgency of the sale and negotiate accordingly.

What are the practical consequences for the seller?

Repaying the outstanding mortgage: the risk of a shortfall

This is by far the most significant consequence of selling a property at a loss.

While a capital loss has no tax implications, it can have an immediate financial impact.

When you sell a property financed by a mortgage, the sale proceeds are used first to repay the outstanding loan balance.

If the net sale price—after deducting any mortgage discharge costs and early repayment charges (ERCs)—is insufficient to repay the remaining capital, the seller must personally fund the difference. Otherwise, the sale cannot be completed before the notary.

No tax relief in return

Unlike shares and other financial investments, where capital losses can generally be offset against capital gains realised during the same tax year or carried forward for up to ten years, French property tax rules provide no equivalent mechanism for privately owned residential property.

A property capital loss:

• does not reduce your taxable income;
• cannot be offset against another property capital gain, even if another property is sold during the same year;
• cannot be carried forward to future tax years;
• does not need to be declared, as it has no tax effect whatsoever.

Worked example: buying for €300,000 and selling for €260,000 in 2026

Let's consider a homeowner who purchased their main residence for €300,000 seven years ago using a 20-year mortgage.

In 2026, the local property market has weakened and a realistic professional valuation places the property's market value at €260,000, taking into account its condition, its E-rated EPC and the general decline in local prices.

Gross capital loss

€300,000 − €260,000 = €40,000

Tax treatment

None.

The capital loss is not taxable, but it does not generate any tax relief either.

Outstanding mortgage balance

Assume that, after seven years of repayments, €210,000 remains outstanding.

Costs associated with the sale

These may include:

• mortgage discharge or guarantee release fees (typically 0.3% to 0.8% of the original loan amount);
• early repayment charges, which are legally capped at the lower of:
  • 3% of the outstanding capital, or
  • six months' interest;
• estate agency fees, where applicable.

Net amount remaining for the seller

€260,000 (sale price)

− €210,000 (remaining mortgage)

− approximately €3,000–€5,000 in additional costs

= a positive remaining balance, but significantly lower than the seller's total investment, including their original deposit, renovation costs and purchase expenses.

In this example, the sale can still proceed without the seller having to contribute additional funds.

However, they lose part of their original investment and recover considerably less than they have spent since purchasing the property.

If, on the other hand, the outstanding mortgage had still been €265,000—perhaps because the property was purchased more recently with only a small deposit—the situation would be very different.

The seller would have to contribute at least €5,000, in addition to the associated sale costs, simply to repay the mortgage and complete the transaction.

The 2026 tax treatment of property capital losses

The general rule: no deduction and no carry-forward

French tax legislation governing capital gains on residential property owned by private individuals is perfectly clear.

A capital loss realised on the sale of a property has no tax effect whatsoever.

It:

• cannot be offset against another property capital gain;
• cannot be deducted from your overall taxable income;
• does not affect your reference taxable income (Revenu Fiscal de Référence – RFR).

There is therefore no requirement to declare the loss on your annual tax return.

This position is confirmed by the official guidance published by the French tax authorities (impots.gouv.fr), which remains the definitive reference on the subject.

This treatment differs fundamentally from the taxation of financial assets, where capital losses on shares, bonds or investment funds may generally be offset against capital gains realised during the same year and carried forward for up to ten years.

No equivalent mechanism exists for privately owned residential property.

A very limited exception

There is one highly specific exception, although it applies only in very unusual professional or investment situations.

Where an entire building has been acquired in successive stages—for example by purchasing individual apartments over time before eventually selling the whole building as a single asset—it may, in certain circumstances, be possible to offset gains and losses arising on the various parts when calculating the overall taxable capital gain.

This mechanism is extremely limited and is not relevant to the vast majority of homeowners, whether selling a main residence, a second home or a conventional rental investment.

Similarly, certain highly specialised tax regimes linked to heritage restoration schemes (such as the Malraux scheme) contain their own specific rules regarding renovation costs and property-related tax deficits.

However, they do not create any general right for private individuals to deduct property capital losses.

If you are unsure whether your own situation falls within one of these exceptional cases, it is advisable to seek advice from a notary or tax adviser before signing the preliminary sales agreement.

What this means in practice

For the overwhelming majority of sellers:

• if you sell your main residence, the question of capital gains or losses is irrelevant because the sale is automatically exempt from capital gains tax;
• if you sell a second home or rental property at a loss, you will pay no tax on the sale, but you will receive no tax relief either;
• the notary, who is responsible for calculating and collecting any capital gains tax due, will simply confirm that no taxable gain exists and therefore no tax is payable.

How to reduce or anticipate a capital loss before selling

Obtain a realistic professional valuation

One of the most common mistakes made by homeowners worried about selling at a loss is overvaluing their property because of emotional attachment or by relying on what they originally paid for it.

This often results in a property remaining on the market for too long before requiring a series of price reductions—usually more damaging than setting a realistic asking price from the outset.

Conversely, undervaluing a property in order to sell quickly unnecessarily increases the financial loss.

An online property valuation provides a useful starting point, but it should always be followed by an on-site appraisal and a detailed analysis of the local market carried out by a property professional.

Only this type of assessment can properly take into account factors such as the property's orientation, condition, renovation work, co-ownership arrangements, EPC rating, surrounding environment and the prices actually achieved by comparable local sales.

Focus on improvements that genuinely add value

Not all renovation work delivers the same return on investment.

Before putting your property on the market, it is generally more worthwhile to focus your budget on:

• energy-efficiency improvements, such as insulation or replacing an outdated heating system, to improve the EPC rating—often the factor with the greatest influence on today's negotiations;
• cost-effective cosmetic improvements, including repainting, replacing worn flooring and enhancing natural light, all of which significantly improve buyers' first impressions;
• upgrading visible rooms, such as bathrooms and kitchens, rather than undertaking major structural work, which is rarely fully reflected in the selling price.

A detailed assessment carried out with the support of a local property consultant helps avoid spending money on improvements that are unlikely to increase the property's market value.

Choose the right time and the right selling strategy

Timing has a direct influence on the risk of selling at a loss.

A property launched onto the market at the right price, with high-quality presentation from the outset, generally sells more quickly and for a better price than one that remains unsold for months before undergoing repeated price reductions.

It is also advisable to:

• monitor local price trends before deciding on your asking price;
• avoid selling, where possible, during periods of sharply rising mortgage rates, which reduce buyers' purchasing power;
• work with a property professional capable of negotiating effectively and identifying genuinely qualified buyers.

What if your outstanding mortgage exceeds the sale price?

Renegotiate your mortgage or speak to your lender

If your property's estimated market value suggests that the sale price may not cover the outstanding mortgage, your first step should be to contact your lender before putting the property on the market.

Several options may be available, including:

• renegotiating or refinancing the mortgage to reduce monthly repayments and gain more time before selling;
• requesting a temporary repayment arrangement if an immediate sale is not essential;
• confirming the exact amount of any early repayment charges, which may sometimes be reduced—or even waived—depending on the terms of the mortgage agreement, particularly following certain life events or professional relocation.

Consider renting the property temporarily instead of selling at a loss

If your financial situation allows, temporarily renting out the property may be a sensible alternative to accepting an immediate loss.

This strategy can:

• give the local property market time to recover;
• allow rental income to continue contributing towards mortgage repayments, reducing the owner's financial burden;
• avoid a rushed sale that would almost inevitably result in a larger discount.

However, this option also requires careful planning.

You should first consider the tax and administrative implications of becoming a landlord, ensure that the property's EPC rating allows it to be legally rented, and verify that neither your mortgage conditions nor your mortgage insurance prevent the property from being let.

Mortgage refinancing and other financial strategies

In certain circumstances, debt consolidation or a refinancing arrangement combining several loans into a single mortgage may allow the sale to be postponed until market conditions become more favourable.

Similarly, negotiating a repayment holiday or revised repayment schedule with your lender may reduce the pressure to sell immediately.

A mortgage broker or wealth management adviser can help assess these financial solutions alongside the property's market outlook.

FAQ

Is a property capital loss taxable in France ?

No. A capital loss realised by a private individual when selling residential property is not subject to tax, because only capital gains are taxable.

No gain simply means that no capital gains tax is payable.

Can I deduct a property capital loss from my other taxable income?

No.

Unlike capital losses on financial investments, a property capital loss cannot be deducted from your overall taxable income or offset against other taxable income.

It is completely tax neutral.

Can I offset a property capital loss against a gain made on another property?

Generally, no.

Private individuals cannot offset one property's capital loss against another property's capital gain, except in the very limited case of the sale of an entire building acquired in successive stages—a situation that applies only to a very small number of investors.

What happens if my sale price is lower than my outstanding mortgage?

You will need to pay the difference—known as the shortfall—from your own funds before the sale can be completed before the notary.

It is therefore essential to ask your lender for an exact statement of the outstanding mortgage balance and any early repayment charges before deciding on your asking price.

How can I find out whether my property is likely to be sold at a loss?

The best approach is to begin with an online property valuation, followed by a detailed appraisal carried out by a local property professional who can compare your property with genuinely comparable sales in your area.

Should I sell at a loss or wait for market conditions to improve?

That depends entirely on your personal and financial circumstances.

If you are not under pressure to sell immediately and your finances allow, waiting for the market to stabilise—or renting the property temporarily—may prove to be the better solution.

However, a well-negotiated sale today is often preferable to a rushed sale carried out under financial pressure, which usually results in an even greater loss.

Can the Energy Performance Certificate (EPC) increase the risk of selling at a loss?

Yes.

Properties with an E, F or G EPC rating often suffer significant discounts because buyers take into account both the cost of future energy-efficiency improvements and the progressive restrictions affecting the rental of lower-performing properties.

Can a property consultant help reduce my capital loss?

Yes.

An experienced property consultant understands local market values, knows which improvements provide the greatest return before selling and has the negotiation expertise needed to minimise price reductions.

They can also help you discuss mortgage repayment options with your lender and develop the most appropriate selling strategy for your circumstances.
