What is a bridge loan?

A bridge loan is a temporary loan that allows a borrower to finance the purchase of a new home before selling their current property. The purpose of a bridge loan is to bridge the financial gap that arises between the purchase of the new home and the sale of the old one.

In this way, this financing acts as a “bridge” between the two transactions, thereby preventing the client from missing out on potential real estate opportunities that arise in this market due to a lack of funds.

Key features 

Short-term financing

A bridge loan typically lasts between 6 months and 2 years, although some banks may allow extensions, provided certain requirements are met.

Mortgage guarantee

Both the new home and the current home can be used as collateral for a bridge loan.

Grace period

In many cases, with a bridge loan, you only pay interest at the beginning.

Limited amount

Generally, a bridge loan covers between 60% and 80% of the purchase price of the new property.

Higher interest rates

Since this is a short-term loan, it typically has a higher nominal interest rate than a traditional mortgage.

You might be interested in: fixed-rate, adjustable-rate, or hybrid mortgages.

Advantages 

Buy without waiting to sell

The main advantage of a bridge loan is that it allows you to avoid missing out on real estate opportunities due to a lack of funds to make a purchase because you haven't yet sold your previous property.

Flexible payment options

Some financial institutions allow you to pay interest only at the beginning of a bridge loan.

Flexible payment terms

If the sale of the property the customer already owns takes longer than expected, some banks may offer extensions on the bridge loan.

You avoid having to rent

A bridge loan can prevent you from having to move into temporary rental housing while you wait to sell your home.

How does it work?

Funding Methods

A traditional bridge loan works by having the bank lend money to the customer to purchase a new home, using the customer’s existing home as collateral.

On the other hand, a cross-collateralized bridge loan works in such a way that the bank uses both properties—the new one and the one the customer already owns—as collateral for the loan.

Payment methods 

The repayment method can be interest-only, with interest paid during the grace period—for example, during the first 12 months—or it can be a lump-sum repayment, which is made when the old home is sold, using those proceeds to pay off the loan in full at once.

What happens if the old house isn't sold in time?

There may be several options if the old house isn't sold in time to pay off the bridge loan.

The first option is to extend the mortgage term; several banks offer the option of granting an extension, provided certain conditions are met.

Another option is to refinance; if you’re unable to sell, you can convert the bridge loan into a traditional mortgage by agreeing to new terms with the lending bank.

Finally, in the worst-case scenario, foreclosure may occur, in which the bank has the right to demand full payment of the mortgage or to seize the property to cover the debt. However, this rarely happens, as there are opportunities beforehand to discuss the matter, negotiate, and reach a mutual agreement with the bank.

Who is it intended for?

A bridge loan is an ideal solution for families looking to buy a home because they need to move due to factors such as work or a lack of space. It is also useful for investors who purchase a new property before selling their current one, and for people who have found a good real estate opportunity they don’t want to miss, so they don’t want to wait to sell their current property before buying it.

What are the requirements to apply?

The requirements for a bridge loan include having a favorable appraisal for both properties—the current one and the new one—having a stable income that allows you to temporarily manage two mortgages, having a good credit history (with no delinquencies on your credit report), having sufficient equity (which generally means having paid off at least 30% of the current mortgage), and having a purchase agreement for the new home.

Which institutions will offer it in 2026?

In Spain, there are several banks that offer bridge loans, although their terms vary.

Unicaja Banco offers financing of up to 70% of the value of the new home, with a maximum term of 24 months.

Bankinter allows for grace periods (during which only interest is paid) and requires a bank guarantee or additional collateral.

BBVA offers a refinancing option in the event that the sale is delayed, but requires a high credit rating.

CaixaBank offers greater flexibility in repayment terms, allowing for terms of up to 36 months in exceptional cases, and requires a mandatory professional appraisal of both properties.

Disadvantages of a bridge loan

Higher financial costs

The interest rates on this type of mortgage are higher than those on a standard mortgage.

Risk of not selling in time

If the market is in a slow sales period, you could end up stuck with two active mortgages.

Additional fees

Some banks may charge additional fees for, for example, setting up a bridge loan, paying it off early, or extending the loan term.

Requirement for additional guarantees

In some cases, financial guarantees or specific life insurance policies may be required to qualify for a bridge loan.

How can you tell if a bridge loan is the best option for you?

A bridge loan is ideal for you if you’re certain you’ll soon sell your current home or property, or if you’ve found a once-in-a-lifetime real estate opportunity. It’s also a good idea to have savings set aside to cover unexpected expenses before taking out this loan.

However, a bridge loan may not be the best option for you if the market is stagnant and you realize it might be difficult to sell your home, or if you can’t afford to make two mortgage payments at the same time, or if you’re someone who prefers to avoid taking financial risks.

Frequently Asked Questions (FAQs)

Can I apply for a bridge loan if I still have a balance on my first mortgage?

Yes, but the bank will assess your ability to pay and the equity in your current home.

What is the interest rate on a bridge loan?

The interest rate on a bridge loan is usually higher than that of a traditional mortgage, ranging from 3% to 6% APR.

Can a bridge loan be paid off early?

This depends on each bank and its terms; some allow early repayment with a fee of 1% to 2%.

Can I apply for a bridge loan if I'm self-employed?

Yes, but you'll need additional documentation to prove your financial stability, such as balance sheets, VAT returns, etc.

What is the difference between a bridge loan and a conventional mortgage? 

The term—since a bridge loan is short-term (1 to 2 years) and a traditional mortgage is long-term (20 to 30 years)—the interest rates—where a bridge loan is more expensive—and the collateral—since a bridge loan typically requires more collateral.
