Buying a new home when you first need to sell your current one presents a practical problem: the mortgage on the new property often costs more than the one you are still paying off. This financing gap, which is rarely anticipated, is blocking or delaying many property projects in 2026. Understanding how it works before you get started can make all the difference, whether you are buying, selling, or both.
Selling before buying again: the interest rate gap trap
You took out your mortgage a few years ago, at a rate far lower than those available today. When you sell your property, you pay off that advantageous loan. Your new mortgage, however, will be taken out at current rates, which are considerably less favourable.
In practical terms, this means that your monthly payments increase even if you buy a property at the same price. The equity you have built up in your old home does not always offset the higher cost of the new interest rate. This is what leads some homeowners to postpone their plans or lower their budget.
Before putting your property on the market, consider these three scenarios:
- Sell first, rent temporarily, then buy: this option secures your financing because your down payment is available, but it involves an interim move and rental costs
- Buy before selling with a bridging loan: the bank advances part of the price of the new property while you wait to sell the old one, but the total cost of the arrangement (bridging loan interest plus the new mortgage) can be substantial
- Negotiate a long completion period with the buyer of your current property: this gives you more time to find and finance your next home, provided the buyer agrees to the delay
None of these scenarios is right for everyone. The choice depends on your remaining borrowing capacity, the local market and how much time you have. To keep up with market trends and compare local conditions, the property market on Veriscope offers useful insights throughout the year.
Property valuations and sale prices: assess each type of property on its own merits
National trends can obscure the very different realities of selling an apartment versus a house. Notaires de France report that house prices and apartment prices are not changing at the same pace. Sellers who rely on a national average risk overpricing or undervaluing their property.
Why does this distinction matter so much? Because buyers are negotiating more firmly than they were two years ago. Buyers’ renewed bargaining power is prompting sellers to set a realistic price from the outset, or risk seeing their property linger on the market.
Energy ratings and the mix of properties sold
An energy performance certificate (DPE) is no longer just a way to assess the work that may be needed. It is changing the very mix of properties being sold. Notaires de France report a rise in sales of homes rated C and D, while the share of homes rated E is falling. Buyers are avoiding energy-inefficient properties or demanding a substantial discount.
Smaller properties are particularly affected: their energy ratings are less favourable than those of apartments overall. If you are selling an older studio or one-bedroom apartment, the DPE will affect negotiations.
Financing and mortgages: what is changing for buyers
The maximum debt-to-income ratio remains capped at 35% of net income, under a rule set by the High Council for Financial Stability (HCSF). The maximum mortgage term is 25 years (27 years for an off-plan purchase, or VEFA).
These two safeguards remain unchanged, but the recent rise in interest rates is automatically reducing the amount buyers can borrow. At the same income level, households can borrow less than they could in 2022 or 2023. Before viewing any properties, getting an accurate estimate from a mortgage broker or bank is still the first practical step.
Zero-interest loan: check whether you qualify
The PTZ remains an option for first-time buyers. Its eligibility criteria have changed in recent years. Check the rules in force when you apply: eligible areas, income caps and qualifying property types change regularly.
Borrower insurance accounts for a significant share of the total cost of a mortgage. Comparing several policies, including those from external providers, can substantially reduce the cost over the life of the loan.
Getting ready to sell: steps that speed up the transaction
A well-prepared property sells faster and leaves less room for negotiation. Here are the steps that make a difference:
- Prepare the required diagnostic reports (DPE, asbestos, electrical, gas, etc.) before listing the property, not after the first viewing
- Set a realistic price from the outset using recent local comparables, rather than adding an arbitrary percentage to the original purchase price
- Present the property well: declutter, carry out minor cosmetic improvements and use high-quality photos. A bright, tidy home attracts more serious viewings
- Be ready to answer questions about service charges, the condominium association and approved or upcoming works, so you do not lose a serious buyer because you cannot respond promptly
Having a complete file ready when you list the property shortens the time between signing the preliminary agreement and completing the sale at the notary’s office. Buyers with financing in place want to move quickly. Sellers who provide all the documents upfront inspire confidence and reduce the risk of buyers withdrawing.
The notary’s role in securing your plans
The notary is involved at two key stages: when the preliminary sale agreement is signed and when the final deed is executed. In between, they check the property’s legal status (mortgages, easements and planning matters). Consulting a notary before putting your property on the market can help identify potential obstacles before a buyer discovers them.
The 2026 property market rewards careful planning. Buyers who know how much they can really borrow and sellers who set a fair price from the outset are more likely to find a match. Ultimately, the biggest risk is getting started without calculating the true cost of moving from one mortgage to another.
