What is a bridging loan and how does it work?

The bridge mortgage is a loan designed so that you can acquire a new home without having finished selling the current one. It acts as a financial "bridge" between both operations: for a limited period, the bank finances the purchase of the new house and allows you to live with the current one. debt on the home you still own, usually with softer payment terms while the sale is being made. If you buy a home under construction, it is a good idea to consider the self-promoter mortgage.
It is usual that, in that initial section, the bank offers a grace period In which you pay only interest or a reduced installment. This interval can vary depending on the institution: some institutions handle windows of 6 months to 5 years, others estimate 1 to 2 years as the most common horizon, and you will also find intermediate options from 2 to 5 yearsOnce you sell your old home, you can use the proceeds to pay off the portion of the loan associated with that home and continue with the mortgage on your new home under standard terms.
This product can be structured in two main ways. On the one hand, under a single loan which mortgages the current home and the new one (they are integrated into a single operation, which simplifies management). On the other hand, as two different loans: The mortgage on the old house is maintained and a new one is opened for the house you are buying, adjusting the installments until the sale is completed. In practice, many entities structure this as a extension of the existing loan by incorporating a second guarantee (the home you purchase).
You must consider that, as long as you do not sell, you can bear the simultaneous payment of two mortgages or, at least, of an interest installment bridge-specific. The key is that this solution provides time flexibility and prevents you from missing out on an opportunity by having to wait to sell first.
Payment modalities during the long weekend
During the bridge period you can choose how you prefer to pay, and entities usually offer three types of quotas with different intensity of effort:
- Normal rate: It is the most similar to a traditional mortgage, because you amortize capital and pay interest From the start, it's useful if your financial means allow for a steady effort and you don't want to extend the interest payments too far.
- Reduced rate: the monthly payment is lower than what you would pay when you only have the new mortgage; a large part goes to interest and a limited portion of capitalIt gives you breathing room while you close the sale, at the cost of slower amortization.
- Interest only with no principal: you only pay the interest during the grace period, without reducing the principalThe fee is the lowest, although the bank may set a shorter grace period.
Structure and usual steps
The process usually follows a logical sequence, with three main milestones which should be clear from the beginning:
- Hiring the bridge: The entity analyzes whether you meet the requirements (solvency, stability, property value, etc.). If they approve the operation, the money is allocated to cover between 80% and 100% of the price of the home you buy and, if applicable, to cancel the outstanding debt on your current mortgage.
- Lack and adjustment of quotas: for a period that usually ranges from 6 months to 5 yearsYou pay interest or a reduced installment, during which time you're expected to sell your old home on the market. This is the period that provides you with the key flexibility of the bridge.
- Sale and reorganization: When you sell your first house, the amount obtained is used to pay off the corresponding part of the loan, frees the old house from burdens and you are left only with the mortgage on the new home under ordinary conditions.
Conditions and requirements that banks ask for
For the bridging mortgage to go ahead, financial institutions require a series of minimum conditions related to the value of the homes, your solvency and the viability of the sale:
- Sufficient equity (net worth): The market value of your current home is evaluated and the appraisal of both propertiesThe bank wants to see sufficient margin to comfortably cover the transaction.
- Realistic probability of sale: They analyze whether the house can be sold in a reasonable time in your area (demand, prices, marketing strategy). A well-constructed sales plan adds points.
- Payment capacity and solvency: As with any mortgage, they will ask you for documentation of income, job stability, bank statements and other supporting documents to measure your debt ratioBanks also usually offer specific conditions for young profiles, check the young mortgage.
Regarding financial margins, it is common for entities to establish that the sum of what you finance for the new home (including expenses) plus the outstanding debt of the first mortgage does not exceed 80% of the combined appraisal value of the two homes. With this limit, some banks can practically cover 100% of the purchase price (and expenses) of the new house. You will also see extended total maturity periods, in the range of 30 to 45 years (for example, the 40-year mortgage), depending on the profile and risk policy of each entity.
Another relevant aspect: there are entities that, if you sell your house and pay off the debt In its whole within the agreed period, no fees apply for this amortization. It is advisable to confirm this in writing in the binding offer and review any Opening commission or partial reimbursement that may exist outside of that assumption.
Advantages and disadvantages of a bridge mortgage
Like any financial solution, the bridge has very positive aspects and also risks that must be carefully evaluated. Here are its main pros:
- Flexibility to move from home: allows you to buy without waiting to sell, ensuring a good opportunity when it appears and avoiding chain operations against the clock.
- Simpler procedures: By covering purchase and sale in a single financing scheme, you reduce the complexity of coordinate deeds and deadlines.
- Light fee at the start: thanks to the lack or the reduced rate, the monthly effort It's more bearable while you find a buyer.
- Opportunity to take advantage of offers: If a home appears that is a 100% perfect fit for you, the bridge helps you not to let it slip away due to lack of temporal synchrony.
And these would be the cons to consider before signing:
- Double potential charge: Until you sell, you may be facing two mortgages or at least an additional interest installment, which requires good liquidity planning.
- Risk of not selling on time: If the market cools down or the price is not well adjusted, it may take longer than expected, lengthening the financial pressure.
- Accrued interest: When you pay only interest, the principal does not go down and the total cost of financing may be higher than if you paid off the capital from the beginning.
Risks, scenarios and practical recommendations
Before you jump in, it's crucial to analyze the market where you'll be selling your house: demand in the area, recent comparable sales, time to market, and trading margins. The clearer you are about your starting price and strategy, more controlled there will be a risk of lengthening the bridge.
Also consider a safety cushion to cover several months of payments if the sale is delayed. Savings that cover between 6 and 12 installments can make the difference between a comfortable transition and a tense situation. It also considers alternative scenarios such as the possibility of rent temporarily housing if offers do not arrive at the expected pace.
Negotiate with the bank the interest rate, the length of the grace period and any relevant commission. Request quotes from several entities and compare them homogeneously: TIN, APR, recurring costs, linked insurance and amortization conditionsGood small print is just as important as good typeface.
If your creditworthiness profile allows it, try to make the grace period the one that best fits the estimated sale time in your area (in some cases, 1–2 years are enough(In others, it may be more prudent to sign for 2–5 years). Adjusting the length of the bridge to the reality of the local market greatly reduces the risk.
Practical example with simple numbers
Let's say your current home is valued at 150.000 € and you still have €75.000 to pay. The house you want to buy costs, including expenses, 200.000 €The total financing you would need to complete both transactions would be €275.000 (€75.000 remaining on your current mortgage + €200.000 from the new purchase).
Now, the bank will review the joint appraisal of both homes. If the combined value is €350.000, the 80% limit would set a maximum of €280.000. Since €275.000 is below that threshold, the technical reserve would be viable, and the entity could finance 100% of the price of the new home (and even its expenses), always complying with the internal policy and your solvency profile.
During the bridge, you could choose to only pay interest, or a reduced fee. As soon as you sell the old home, you pay off the corresponding portion, free up the mortgage and convert the scheme into a standard mortgage on the new home, with a monthly payment. normalized and stable.
Associated costs and pricing policies for related services

That is, the final fee It may depend on the final price signed at the notary's office.
If you opt for comprehensive management services with guaranteed rent (for example, while you wait an offer to purchase), the rate that will be applied will be the one that is finally linked to the rental income achievedAlways confirm in writing how these fees are calculated, when they accrue, and under what circumstances they may vary.
How to choose an entity and help tools
To find the best bridging mortgage, compare proposals from several entities: grace periods, maximum percentage on the joint appraisal, interest rates, fees, and the possibility of financing expenses. Some banks publish buying guides and offer simulators so you can anticipate payments in different scenarios; some entities, such as Caja Rural del Sur, have informative materials and mortgage simulators useful for making basic numbers before sitting down to negotiate.
