Are you already a homeowner and have found your next property, but your current home has not yet been sold? This situation can quickly become complicated: should you wait until the sale is completed and risk losing the new property, or is there a way to buy before selling?
A bridging loan in Luxembourg may, depending on your situation and the solutions offered by lenders, help bridge the financial gap between the two transactions.
However, this type of financing needs to be carefully planned. The value of the property you are selling, the outstanding balance on your existing mortgage, the time required to find a buyer and your ability to temporarily cover several financial commitments all need to be considered.
Here is what you need to know before considering a bridging loan in Luxembourg in 2026.
What is a bridging loan?
The principle of a bridging loan is relatively simple.
You own a property that you intend to sell in order to finance part of your next purchase.
The problem is that you have already found your future home before completing the sale of your current property.
In this situation, a lender may consider providing temporary financing based on part of the funds expected from the sale.
Once your previous property has been sold, the proceeds can then be used to repay the bridging finance according to the terms set out in your loan agreement.
It is therefore a temporary financing solution designed to bridge the gap between two property transactions.
Why buy before selling?
In an ideal scenario, you sell your current home, receive the proceeds and then purchase your new property.
In practice, however, the timing of the two transactions rarely matches perfectly.
You may find the ideal house while your current apartment has only just been put on the market.
Waiting could mean losing the opportunity to purchase that property.
On the other hand, buying immediately without having secured the sale of your existing home can make your financial situation significantly more complex.
Bridging finance is designed to address precisely this timing issue.
How does a bridging loan work in Luxembourg?
The exact terms depend on the lender and your financial profile.
The bank will generally assess how much money is likely to become available when your current property is sold.
It may consider factors including:
- the estimated value of your current property;
- the outstanding balance on your existing mortgage;
- the purchase price of the new property;
- your available deposit or savings;
- your income;
- your existing financial commitments;
- the circumstances surrounding the planned sale.
The lender will therefore not simply rely on the price at which you hope to sell your property.
It also needs to assess whether the property can realistically be sold under suitable conditions and within the expected timeframe.
How much can you borrow with a bridging loan?
There is no universal amount.
The financing available will depend in particular on the value of the property you intend to sell and the amount you still owe on it.
Let’s take a simplified example.
You own an apartment valued at €600,000, but you still have €200,000 left to repay on the existing mortgage.
Selling the property for €600,000 does not therefore mean that you will have €600,000 available for your next purchase.
The outstanding mortgage and any costs associated with the transaction must also be taken into account.
The lender may also use a conservative valuation rather than automatically assuming that the property will sell for your desired asking price.
An individual assessment is therefore essential.
How does the bank value your current property?
The value of the property being sold is one of the key elements of the financing process.
An overly optimistic valuation can weaken the entire financial plan.
Imagine that your financing is based on a sale price of €800,000, but market conditions ultimately mean that you can only find a buyer at €720,000.
That difference could have a significant impact on your financing.
It is therefore preferable to work with a realistic estimate of the property’s market value.
Depending on the situation, obtaining several valuations may help provide a more accurate picture of the likely selling price.
What if your property is not yet on the market?
The further your sale has progressed, the easier it becomes to assess the likely conditions of the transaction.
A property that is already on the market, realistically priced and attracting viewings is not in the same position as a property that has not yet been listed.
If you are considering buying before selling, it may therefore be worthwhile to prepare the sale of your current property as early as possible.
This can also give you a clearer idea of how long it may take to find a buyer.
Can you have two mortgages at the same time?
During the transition period, you may temporarily have several financial commitments relating to both properties.
This is one of the main issues that needs to be anticipated.
The lender will need to check that the proposed financing structure remains compatible with your income and overall financial situation.
Depending on the arrangement, you may temporarily need to cover different loan payments, interest charges or other costs.
You should also consider the expenses associated with maintaining two properties, such as:
- insurance;
- service charges;
- energy bills;
- maintenance;
- applicable taxes and fees;
- moving costs.
The cost of this transition period should therefore be included in your overall budget.
What is the main risk of a bridging loan?
The main risk is straightforward: your existing property may not sell under the conditions you originally expected.
It may take longer than anticipated to find a buyer.
You may also need to reduce the asking price.
A bridging loan is a temporary financing solution, so your new property purchase should not be based on an overly optimistic sale scenario.
Before committing, consider questions such as:
- Is my expected sale price realistic?
- How long are comparable properties taking to sell?
- What happens if I have to lower the price?
- Can I financially manage a longer transition period?
- What is the term of the bridging finance?
These scenarios should be considered before signing.
Is it safer to sell before buying?
In many situations, selling before buying can make the financing process simpler.
You know exactly how much capital is available for your next purchase.
You also avoid uncertainty about how long it will take to sell your existing property.
However, this strategy creates another potential issue: you may need temporary accommodation between the two transactions.
You may also sell your current home before finding a new property that genuinely meets your requirements.
There is therefore no single strategy that is suitable for every homeowner.
Bridging loan or selling first: how should you decide?
The right approach depends mainly on your personal circumstances and the property market.
Buying before selling may be worth considering if you have found a property that closely matches your requirements and your existing home is likely to sell under reasonable conditions.
Selling first may be a more cautious approach when the value of your property is uncertain or when your finances would make it difficult to manage an extended transition period.
Your level of savings also matters.
The larger your financial reserve, the better positioned you may be to deal with unexpected developments between the two transactions.
What happens if your property sells for less than expected?
This is one of the scenarios you should consider before committing to your next purchase.
Suppose your financing plan is based on selling your existing property for €700,000.
If you eventually have to accept an offer of €650,000, your original plan is suddenly €50,000 short.
That difference must either be financed in another way or covered using your savings.
Before committing to your new property, it may therefore be useful to consider several scenarios:
- a sale at the expected price;
- a sale slightly below the expected price;
- a sale significantly below the expected price;
- a sale taking longer than anticipated.
Ideally, your overall project should remain financially manageable under several different scenarios.
Can you use your savings alongside a bridging loan?
Yes. Depending on the financing structure, your savings can form part of the overall financial plan.
However, as with a conventional property purchase, using all your available savings is not necessarily the best option.
Keeping a financial reserve may be particularly important when buying and selling at the same time.
You may need funds to cover:
- two properties during the transition period;
- moving costs;
- renovation work;
- a lower-than-expected sale price;
- unexpected expenses.
Your contribution should therefore be considered as part of the overall financing strategy.
What happens to your existing mortgage after the sale?
If there is still a mortgage attached to the property being sold, the way it is handled will depend on your loan agreement and the structure of the transaction.
The outstanding balance must be taken into account when calculating how much money will actually remain available after the sale.
You should therefore never automatically assume that:
sale price of your existing property = funds available for your new property.
The actual calculation is more complex.
Before buying, make sure you have a clear picture of the amount still outstanding and any conditions that apply to your existing mortgage.
Can you keep your existing property and rent it out?
Some homeowners eventually decide not to sell their current property and instead rent it out.
This fundamentally changes the nature of the project.
Rather than a conventional buy-and-sell transaction, you now need to consider a financial situation involving two properties.
Potential rental income, the outstanding mortgage, ongoing costs and the new mortgage payment will all need to be assessed.
The fact that a property can potentially be rented does not automatically mean that a lender will treat the full expected rental income as available income.
The financing therefore needs to be reassessed.
When should you start preparing the financing?
As early as possible.
Do not wait until you have committed to purchasing the new property and received an offer on your existing home before thinking about the financing.
Ideally, before seriously searching for your next property, you should already know:
- the realistic value of your current property;
- the outstanding mortgage balance;
- your available savings;
- your borrowing capacity;
- your budget for the next property;
- the different financing options available during the transition.
This will help you determine whether buying before selling is realistic for your situation.
Why use a mortgage broker for a buy-and-sell project?
A project involving both the sale of an existing property and the financing of a new one involves more variables than a standard first-time purchase.
Two transactions need to be coordinated even though their timelines can change.
A mortgage broker can analyse your financial situation, your existing mortgage, the value of the property you intend to sell and the amount required for your next purchase.
Prêt Immo can then review different financing solutions and compare proposals according to your project.
The objective is to build a financing structure that does not depend solely on the most favourable scenario.
Are you planning to buy before selling your current property?
Before committing to your next purchase, have the entire transaction assessed.
The value of your current property, your outstanding mortgage, your savings, your income and the purchase price of your future home should all be considered together.
