Selling your house while keeping your mortgage is an option that appeals to many homeowners, especially when their loan interest rate is attractive. Whether this strategy is possible and worthwhile depends on the type of loan, the clauses in your contract (transferability, portability), and your bank's approval. Before making any decisions, it's essential to understand the legal and financial mechanisms involved (mortgage, early repayment, borrower insurance) and anticipate the consequences for your future plans.
Understanding the Relationship Between Selling a Home and the Mortgage
What Is a Mortgage and How Is It Tied to the Property?
A mortgage loan is financing provided by a bank to purchase a property; it covers a loan amount to be repaid over a set period, with monthly payments and an interest rate.
To secure the loan, the bank typically requires a guarantee: a mortgage, surety, or other security. This guarantee legally links the loan to the property being financed. If you sell the property before repaying the loan in full, the bank can require full repayment of the outstanding balance, including any early repayment penalties (ERP). These penalties are often capped (typically around 3% of the remaining principal) and generally equal to about six months of interest.
In addition, lifting the mortgage requires a notarized deed once the loan is repaid. As a general rule: selling your house or apartment usually means paying off or transferring the mortgage tied to the property.
The Differences Between Standard Loans and Assisted Loans
Not all home loans are equal when it comes to retaining them after a sale. Standard mortgage loans (typical amortizing loans) can, under certain contractual conditions and with the bank’s approval, be transferred to a new property.
However, assisted loans — such as the zero-interest loan (PTZ), regulated home loan (PC), or social home ownership loan (PAS) — are subject to stricter rules. The possibility of transferring these loans is often time-limited (e.g., within the first 6 years after disbursement) and conditional upon meeting the eligibility criteria of the assisted loan for the new property.
If these conditions are not met, the bank will require full repayment of the assisted loan at the time of sale. Therefore, it’s essential to carefully review your contract and verify whether a transferability or portability clause is included, as this determines your flexibility when selling a house or apartment.
Transferring a Mortgage: A Way to Keep Your Low-Interest Loan
Eligibility Requirements for Transferring a Mortgage
Loan transfer allows, under certain conditions, the original mortgage to be attached to a new property so that you can retain the interest rate — and sometimes the borrower insurance. To be eligible, your loan agreement must explicitly include a transferability or portability clause.
Next, the bank must approve the transfer: it will reassess your financial situation (income, debt ratio, disposable income) and confirm that your new project is compatible with the existing loan (amount, remaining term, use as a primary residence).
In the case of assisted loans, additional conditions apply: the new property must meet the eligibility criteria of the PTZ/PAS/PC if the transfer is requested within the permitted time frame.
Lastly, some technical steps are required (mortgage release, application fees, possible reassessment of the insured amount), and your borrower insurance may need to be reviewed.
Advantages and Limitations of Mortgage Transfer
The advantages are immediate: retaining a favorable interest rate in a rising rate environment, saving on fees related to a new mortgage (application fees, sometimes brokerage fees), and avoiding early repayment penalties if the transfer is accepted. Keeping the same borrower insurance may also be possible, offering additional savings.
However, in practice, mortgage transfer is increasingly rare, and banks are more cautious. They may refuse the transfer, impose fees (mortgage release, processing fees), or demand additional guarantees.
Moreover, if your current loan has a high interest rate or terms that don’t match your new project (e.g., different loan amount or property use), the transfer might not be suitable. Lastly, portability and transfer clauses are uncommon in recent contracts, making it crucial to anticipate and negotiate these clauses when taking out a mortgage.
Alternatives to Keeping the Mortgage When Selling
Early Repayment of a Home Loan: Costs and Process
Paying off your mortgage early is the most straightforward solution when transferability is not possible or not relevant. Before deciding, calculate the exact remaining principal and the early repayment penalties (IRAs), which are generally capped at 3% of the outstanding balance or the equivalent of six months of interest.
Add to that the mortgage release fees (notarial act) and any bank processing charges. Practical steps: request an up-to-date amortization schedule from your bank showing the exact payoff amount, accrued interest, and IRAs.
Notify your notary early so that the mortgage release can be planned for the day of sale. On signing day, the sale proceeds are used to repay the loan; the notary pays the bank and registers the mortgage release.
Pros: simplicity and a clean legal end to your debt.
Cons: immediate cost (IRAs + notary fees) and possible loss of a favorable interest rate.
Tip: Compare the total cost of early repayment with the potential savings from keeping your original interest rate. If the penalties are low and you’re avoiding a much higher market rate on a new loan, paying off the mortgage might be your best option.
Loan Buyback and Bridge Loan: What Are the Benefits?
If mortgage transfer is not possible when selling a property, other financing solutions can help you avoid getting stuck between selling and buying.
Loan buyback involves having your current loan taken over by another financial institution, which consolidates your debts or offers a new loan for your next purchase. The new lender repays your old loan and may offer better terms (interest rate, duration, etc.).
Benefits: possibility of getting a lower overall interest rate, extending the loan term to reduce monthly payments, or consolidating several loans into one.
Drawbacks: fees for processing, new guarantees, and possibly early repayment penalties that must be included in your calculations.
Tip: Shop around or use a mortgage broker to optimize your new loan offer.
Bridge loan: a temporary financing solution for buying a new property before selling the current one. The bank advances part of the appraised value of your existing property (usually 60–80%) to finance the new purchase.
There are two types:
Simple bridge loan: if no additional financing is needed.
Bridge loan with conventional mortgage: if you need to borrow more for the new home.
Some banks also offer grace periods, allowing you to delay interest payments.
Pros: immediate cash flow, no need to repay your existing loan right away.
Cons: higher interest rates, need for a realistic valuation of the property being sold, and risk if the sale is delayed.
Practical tip: simulate all three scenarios — transfer, buyback, and bridge loan — with your broker or advisor. Compare total costs, monthly payments, and risks, and choose the solution that minimizes the overall financial impact on your project.
Practical Questions to Ask Your Bank Before Selling and Keeping Your Mortgage
Verify the Transferability and Portability Clauses in the Loan Contract
Before listing your property for sale, carefully review your mortgage contract and ask your bank these key questions:
Does my contract include a transferability or portability clause?
If so, what are the specific conditions (main residence only, minimum transferable amount, time limits since the loan was issued, associated fees)?
If not, would the bank consider an exceptional transfer?
Request a written response from your bank outlining the financial terms and fees (application fees, mortgage release costs, guarantee updates).
Prepare your financial documents: bank statements, payslips, tax returns, property valuation, and new purchase project details.
The bank will re-evaluate your solvency and the profile of the new property.
If possible, obtain a written pre-approval, including key dates (transfer deadline, time allowed between sale and purchase).
Adapting Borrower Insurance to a New Project
Borrower insurance is often linked to the initial mortgage and may be affected by a loan transfer or buyback.
Key questions to ask your bank or insurer:
Can I keep the same insurance if I transfer my loan?
Does my current coverage apply to the new property, my age, or financial profile?
Will there be a surcharge if the insured amount changes?
If you're considering a loan buyback, compare external insurance offers (through a delegation of insurance) to reduce your total cost.
If you want to keep the existing insurance, request an update of the information (new property address, insured capital amount) and written confirmation that your coverage remains valid.
If the insurance is denied, ask for justifications (age, health status, loan terms), and explore alternatives.
Also, be aware of deadlines and procedures: cancelling or transferring an insurance policy may require formal steps and notice periods.
? Final tip: compare banks and insurers, work with a mortgage or insurance broker to optimize rates and guarantees, and always ask for detailed simulations to clearly understand the impact on your monthly payments and budget.
Why and When Keeping Your Mortgage After Selling Makes Sense
Financial and Strategic Advantages
Keeping your mortgage can be a smart move if your current loan conditions are significantly better than current market rates.
Holding on to a low interest rate can result in substantial savings over the remaining loan term — even a 0.5% difference may mean thousands of euros saved.
Other key advantages:
Budget stability: by keeping the same repayment schedule and possibly the same borrower insurance, you avoid a sudden increase in monthly payments that could affect your financial flexibility.
Cost savings: if the transfer is accepted, you avoid early repayment penalties and fees linked to setting up a new loan.
Faster project execution: in a competitive real estate market, keeping your existing loan can simplify financing and make it easier to transition between properties.
Investment strategy: for rental investments or second homes, retaining a low-rate mortgage can improve your net return.
To decide wisely, compare the total cost of all options (transfer vs early repayment + new loan), including penalties, mortgage release fees, application fees, new insurance cost, and rate differences.
Ask for a clear numerical simulation to see the full financial picture.
The Risks and When Loan Transfer Is Not Advisable
Keeping your mortgage isn’t always the best solution. Several situations may justify not transferring your existing loan:
High original interest rate: If your current loan has a higher rate than market offers, maintaining it might cost you more overall.
Project incompatibility: A major change — like buying a much more expensive property or changing its intended use — may make the transfer impossible or require additional guarantees.
Bank refusal or strict conditions: The bank might decline the transfer or only allow it with hefty fees or a renegotiation of guarantees.
Disproportionate additional costs: If release fees, application costs, guarantees, or insurance surcharges offset the benefits of the low rate, the transfer may not be worthwhile.
? Another risk: relying on a verbal agreement. Always request a written, itemized confirmation of the transfer terms (amount, fees, timeline).
Lastly, if your project requires flexibility (e.g. mandatory prior sale, uncertain timing), you may be better off choosing alternatives like a bridge loan or credit buyback rather than counting on a transfer that may not happen.
