Selling a second home does not follow the same rules as selling a main residence, particularly when it comes to taxation. Any capital gain is generally taxable, although allowances based on the length of ownership and certain specific exemptions may apply.
The market for these properties, often located in tourist areas, is also highly seasonal, which directly influences both the sale price and the time needed to find a buyer.
This article explains the applicable tax rules, the best times to sell depending on the type of property, the appropriate valuation method and the precautions to take when selling remotely.
Key Takeaways
The sale of a second home is subject to capital gains tax, unlike a main residence, which generally benefits from a full exemption.
Progressive allowances based on the length of ownership provide a full exemption from income tax after 22 years and from social security contributions after 30 years.
Certain specific situations may qualify for exemptions, including the first sale of a property other than the main residence under certain conditions, some low-income retirees or disabled people, and compulsory purchases.
Market seasonality varies significantly depending on the destination: mountain, coastal and countryside properties do not have the same optimal sales periods.
A reliable valuation of a second home should be based on relevant local tourist-market comparables and seasonal demand, rather than solely on conventional residential prices per square metre.
Preparing the sale several months before the high season and working with a local professional remains the most effective strategy, particularly when selling remotely.
Second Home vs Main Residence: Fundamentally Different Tax Rules
The Exemption for Main Residences
Under French tax law, capital gains made on the sale of a main residence are fully exempt from capital gains tax, provided the property is the seller's usual and actual home at the time of the sale.
This exemption does not apply to a second home, whether it is a holiday home, a pied-à-terre or an inherited property that you only occupy occasionally.
In practical terms, as soon as the property being sold is not your main place of residence, any capital gain falls within the scope of taxation, which can significantly affect the overall financial outcome of the transaction.
Calculating the Taxable Capital Gain
The capital gain is calculated by subtracting the purchase price—plus acquisition costs and, subject to certain conditions, eligible renovation costs—from the net sale price.
The resulting amount is subject to income tax at 19%, plus social security contributions of 17.2%, giving a combined rate of 36.2% before allowances are applied.
An additional surtax may also apply when the capital gain exceeds €50,000, which can particularly affect high-end second homes or properties located in areas where prices have risen significantly.
Allowances Based on Length of Ownership
The key mechanism governing the taxation of second homes is the progressive allowance based on how long the property has been owned.
For income tax, the capital gain becomes fully exempt after 22 years of ownership. For social security contributions, full exemption is reached after 30 years.
Between these two thresholds, the allowance increases progressively each year according to a statutory scale.
For example, a property owned for around 15 years will already benefit from a significant allowance, whereas a property resold only a few years after purchase will be taxed on almost the entire capital gain.
The length of ownership should therefore be taken into account at an early stage when considering the sale of a second home.
Specific Capital Gains Tax Exemptions
Certain situations may qualify for partial or full exemption even when the property is not the seller's main residence.
This may apply to the first sale of a property other than the main residence, provided the seller does not already own their main residence and reinvests the sale proceeds in the purchase of one within the prescribed timeframe.
People holding certain disability cards or low-income retirees may also qualify for exemptions subject to income requirements.
Finally, a sale resulting from compulsory purchase may also be exempt from the standard taxation rules if the compensation received is reinvested under the required conditions.
These situations are specific and should be checked with a notary or tax advisor before making a decision.
Why Do Owners Decide to Sell Their Second Home?
The reasons for selling a second home often differ from those for selling a main residence. Several motivations are particularly common:
The property is used less frequently: as children grow up and holiday habits change, the family home may eventually be occupied for only a few weeks each year, making its maintenance disproportionate to its actual use.
The cost of maintaining the property remotely: property tax, insurance, frost-protection heating, garden maintenance and roof repairs represent ongoing expenses that can be difficult to manage when the owner lives far away.
Inheritance or division between heirs: second homes are often family properties inherited by several children, and selling can simplify the division of the estate or release cash.
A change in personal circumstances: relocation, divorce, a new investment project or simply a desire to diversify holiday destinations can also lead owners to sell.
In several of these situations, the reasoning is similar to that of owners who decide to sell their house and move to a smaller property once their children have left home—a broader trend affecting both main and second residences.
Market Seasonality: When Should You Sell Depending on the Property?
The second-home market is closely linked to the tourist calendar, setting it apart from the sale of a conventional property in a city centre.
Demand fluctuates significantly depending on the season and destination, directly affecting both the number of potential buyers and their ability to imagine themselves using the property.
Selling a Holiday Home in the Mountains
For a chalet or apartment in a mountain resort, the best time to attract buyers is generally before the winter season, between early autumn and the first weeks of December.
Potential buyers often visit the resort ahead of their own ski holidays and are already thinking about future seasons.
A second attractive window exists in spring, when buyers who have recently enjoyed a ski holiday may consider purchasing a property for the following year while their experience of the area is still fresh.
Selling a Holiday Home by the Sea
For a coastal property, the logic is reversed.
The best period to sell a second home by the sea is often in spring, before the summer high season, when buyers begin planning their future holidays and may want to complete a purchase in time to enjoy the property during the summer.
Putting a property on the market in August may seem logical because there are many visitors in the area, but this leaves little time to complete the transaction before the end of the season.
Many buyers also prefer viewing properties outside the busiest tourist periods.
Second Homes in the Countryside or Towns
Properties located in rural areas or towns with strong heritage appeal tend to experience less pronounced seasonality.
However, spring and early autumn generally remain attractive periods, as the weather and natural light help showcase the property during viewings.
In all cases, a local property professional will be best placed to adapt the sales timetable to the specific dynamics of the area.
Valuing a Second Home: An Approach Adapted to the Tourist Market
Valuing a second home cannot rely solely on the same criteria used for a conventional residential property.
Tourist markets can follow very different pricing patterns from permanent residential markets, meaning several specific factors need to be considered:
Relevant local comparables: prices within a mountain resort or coastal town can vary considerably from one area to another depending on proximity to ski slopes, beaches or the town centre.
Seasonality of demand: a property listed outside the optimal period may take longer to sell, which should be taken into account when setting the pricing strategy.
Holiday rental potential: many second-home buyers also consider potential seasonal rental returns, meaning the property's capacity, proximity to amenities and potential occupancy rate can affect its value.
Condition and specific amenities: good insulation, a heating system suited to intermittent occupation, a ski storage area or a well-positioned terrace can all have a significant impact on the property's value.
To obtain a reliable valuation that takes these factors into account, an online property valuation carried out with the support of a professional familiar with the local market provides a useful starting point before refining the figure through an on-site visit.
Sales Strategy: Prepare Ahead of the High Season
Given the seasonal nature of the market, the best strategy when selling a second home is to prepare the property for sale several months before the period of highest demand.
A property listed too late may miss some of the most motivated buyers—those who are already planning their next season in the area.
Preparing the sale in advance, on the other hand, allows you to benefit from a natural peak in viewings, often concentrated within a few key weeks depending on the destination.
In practical terms, this means preparing the property—surveys, photographs and administrative documents—as soon as the previous season ends, setting a price that reflects the local market from the outset rather than adjusting it after several months without an offer, and advertising it through suitable channels.
Setting the right price from the beginning also avoids the negative effect of a property remaining on the market for too long, which can cause buyers to wonder whether there is an underlying problem.
Selling a Second Home Remotely: Precautions to Take
Many second-home owners do not live close to the property, making some stages of the sale more complicated and requiring additional preparation.
Entrust viewings to a local professional: a locally based advisor can organise viewings, answer specific questions about the neighbourhood or resort and respond quickly to buyer enquiries without waiting for the owner to travel.
Secure access to the property: a key safe, leaving the keys with a trusted third party or using a local agency can avoid time-consuming and expensive journeys.
Prepare surveys and administrative documents in advance: the DPE, mandatory surveys, title deeds and recent energy bills should be gathered beforehand to avoid delaying the preliminary sale agreement once a buyer has been found.
Arrange a notarial power of attorney if travelling to sign the final deed is not possible, allowing a third party or the notary to complete the transaction on your behalf.
Remain available and responsive despite the distance, as an interested buyer will generally expect a quick response and may otherwise turn to another property.
This situation is similar to that faced by owners who need to sell a property remotely following a job relocation, as the logistical challenges are largely the same.
Work with an Optimhome Real Estate Advisor
Selling a second home involves combining specific tax considerations, strong market seasonality and, in some cases, managing the transaction remotely.
Working with a local Optimhome real estate advisor provides access to detailed knowledge of the relevant tourist market, support with viewings and negotiations even when you are not present, and advice on the best time to launch the property onto the market.
With more than 1,800 independent advisors across France, the Optimhome network can provide a local point of contact close to your second home, whether it is in the mountains, on the coast or in the countryside.
This local presence can often make the difference between a property remaining on the market for several months and a transaction completed at the right time and at the right price.
Conclusion
Selling a second home requires a different approach from selling a main residence, both in terms of taxation and the timing of the sale.
Capital gains are generally taxable, with progressive exemptions depending on the length of ownership and certain specific exemptions that should be assessed on a case-by-case basis.
The best time to sell depends heavily on the destination: before winter for mountain properties and before summer for coastal properties.
A reliable valuation should take into account local tourist-market comparables and seasonal demand, rather than relying solely on average residential property prices.
Preparing the sale several months before the high season remains the best way to reach the most motivated buyers.
Selling remotely requires careful organisation and support from a local professional to prevent delays or complications.
Working with an experienced professional remains one of the best ways to secure every stage of the process, from valuation through to completion.
FAQ
Is Capital Gain on a Second Home Always Taxable?
In principle, yes, unless allowances based on the length of ownership or one of the specific statutory exemptions applies, such as the first sale of a property other than the main residence subject to reinvestment conditions.
It is advisable to check your individual circumstances with a notary before selling.
How Long Do You Have to Own a Second Home Before the Capital Gain Is Fully Exempt?
The capital gain is fully exempt from income tax after 22 years of ownership and from social security contributions after 30 years.
Between these thresholds, progressive allowances apply each year according to the statutory scale.
What Is the Best Time to Sell a Second Home by the Sea?
Spring, before the summer high season, is generally the most favourable period because buyers are looking to complete their purchase before summer so they can enjoy the property during the warmer months.
Listing too late, during the height of summer, leaves little time to complete the transaction before the end of the tourist season.
What About a Holiday Home in the Mountains?
The best period is generally before the winter season, between early autumn and the beginning of winter, when potential buyers are planning their upcoming ski holidays.
A second opportunity exists in spring, when buyers may have recently discovered and enjoyed the area during a stay.
How Should You Value a Second Home in a Tourist Area?
The valuation should be based on relevant local comparables specific to the resort or coastal area, while also taking seasonal demand and the property's holiday rental potential into account.
An online property valuation carried out with the support of a local professional can help refine the asking price before the property is listed.
Can You Sell a Second Home Without Travelling to the Property?
Yes, provided the sale is properly organised in advance.
You can entrust viewings to a local advisor, gather all mandatory surveys and administrative documents beforehand, secure access to the property and arrange a notarial power of attorney if you cannot attend the signing in person.
Should You Use a Professional to Sell a Second Home?
It is strongly recommended, particularly if you do not live close to the property or if the sale takes place in a more complex context such as an inheritance.
A real estate advisor can provide local market expertise, identify the right sales window and support the transaction from the initial valuation through to completion.
