What is mortgage subrogation?

Generally, mortgage subrogation involves improving certain details of a mortgage loan. This is done to introduce modifications to it, regarding the debtor, or even the creditor entity (bank).

In this sense, the Royal Spanish Academy (RAE) defines subrogate as to substitute or put someone or something in place of another person or thing. Thus, in credit terms, subrogating allows the mortgage loan holder or the bank itself to make certain adjustments to the loan. This is done without having to pay off the existing debt and open a new one.

It is a process that can be advantageous at certain points in the loan, especially if the holder finds more beneficial conditions in the market. It can also be advantageous when the implicit responsibility in the matter is transferred to a third party.

How many types of subrogations are there?

The mortgage subrogation implies for the debtor or the creditor of a mortgage loan the possibility of being substituted or replaced. This can be done by another debtor or banking entity, giving rise to two ways of doing it, which we will address immediately.

Debtor mortgage subrogation

This involves changing the holder of the credit in question, and represents the most common way if the property is mortgaged. In such a case, the bank is authorized to accept or reject the new debtor. Therefore, it will first conduct a risk assessment similar to what it would perform for granting a loan.

This way, the existing commitment can be assumed without incurring new tax payments. However, the inherent costs of the process must be paid.

Creditor mortgage subrogation

This act involves transferring the mortgage from one banking entity to a new one, and it often provides improvements for the credit holder. This applies to their loan terms, and the best part is that they could do so without having to pay it off or formalize a new one.

This way, one can benefit from a modification in the operation's conditions and the amortization period, without incurring tax payments. However, it also requires paying certain associated costs.

How does it work?

The financial act known as mortgage subrogation follows a series of steps that allow the holder to redirect the agreement to another financial entity. It can also facilitate transferring the mortgage to a new buyer. To explain it, we provide details below regarding the aforementioned scenarios.

How to subrogate a mortgage? Step by step

The points to address for managing a mortgage subrogation, we will discuss next.

Track offers to compare available options

It's very important to compare the mortgages available in the banking market to identify the most beneficial plan for you. Today there are online comparison tools for these to facilitate your analysis, considering factors such as interest rates, fees, and repayment period.

Notify the bank

The financial institution holding your mortgage must be notified of your intention or desire to remortgage. This is when the bank will assess whether to present a counteroffer to retain you as a client.

Evaluate existing offers

After receiving the counteroffer, the homeowner can compare the different options. Once this is done, they simply need to choose the one that best suits them, considering financial conditions such as additional associated costs.

Formalize the remortgage

Once a decision has been made, the intention is simply formalized through the required public deed. Additionally, the costs inherent to the act must be paid, both at the notary and the corresponding registry.

What are the requirements?

For a bank to approve the mortgage remortgage you're seeking, there are some requirements the homeowner must meet, such as:

  • Economic stability. The applicant must have a stable financial transaction history and no other outstanding debts. To improve the chances of success, it is essential to have an indefinite employment contract.
  • Good payment record. Another crucial aspect for this purpose is having punctually paid the mortgage installments for at least 2 years.
  • Amortization percentage. Generally, the outstanding capital to be amortized must be equal to or less than 80% of the property's value.

By meeting each and every one of these requirements, you will undoubtedly have a greater chance of achieving the desired remortgage.

How long does it take to complete a mortgage subrogation?

Having a mortgage subrogation could take between 1 and 3 months. It all depends on the flexibility of the financial institution and your speed in gathering the required documents.

Transaction costs

Regarding the associated costs, these include:

  • Notary and registration fees. These are unavoidable expenses, as the new mortgage must be formally registered.
  • Management fees. There are instances where some banking entities require the involvement of an administrative agent in carrying out the procedures.
  • Subrogation fee. For fixed-rate mortgages, this typically involves 0.5% for the first 5 years, and 0.25% thereafter. For variable-rate mortgages, the maximum is 0.25% during the first 3 years, and 0.15% up to the 5th year.

As you can see, there are several considerations to take into account regarding the costs of the process.

Who pays the costs?

Generally, the debtor must bear the associated costs, although the destination financial institution might cover some of these to attract clients.

Benefits of mortgage subrogation

Choosing to obtain a mortgage subrogation could offer you numerous advantages, benefiting both the original and the new holder. In summary, these could include the following.

Advantages for the Debtor

When a type of mortgage subrogation by the debtor occurs, savings are made as a result of the act, by avoiding the need to take on a new loan. This way, it avoids certain expenses, such as those involved in a new transaction, and also some taxes like the IAJD.

Advantages for the Creditor

This scenario implies improvements in interest payments because they are reduced, meaning there was a change in the mortgage. This could involve switching from fixed to variable or vice versa. Additionally, it allows the current Euribor to change to use the IRPH as a reference. Furthermore, it involves extending amortization periods, eliminating clauses, ties, and waiving cancellation fees.

As you can see, this type of action could lead to improved financing conditions, avoiding cancellation fees, and also provides credit flexibility. All these factors, together or separately, will ultimately benefit you as long as you use this financial resource appropriately.
