Mortgage brokers in Spain: iAhorro, Trioteca, Gibobs, Bayteca and others
Banks run two pricing channels: branch and intermediary. The intermediary channel is cheaper. A mortgage broker gives you access to that second channel — conditions the branch manager can't offer you even if they wanted to. The best-known in Spain — iAhorro, Trioteca, Gibobs, Bayteca — are free for you: they charge the bank you end up signing with.
How they work and why they can get you better terms than walking into a branch
Large brokers have volume agreements with banks. That means they access lower rates, fewer bundled products, or both. This isn't theory. A user who worked in banking confirmed it: "I checked Caixa and Cajasur in person, then went through a broker — prices much better and far fewer conditions. I don't understand it, but that's what I found."
A Caixabank manager put it more plainly: to get good conditions without heavy bonus obligations, you have to go through an online broker. Walk into a branch and they'll load you up with conditions; through the intermediary channel, they won't. Same bank, two prices. The branch charges more because it can.
The bank pays the broker's commission — it's usually detailed in the FEIN (binding offer document). For iAhorro, the typical commission is around EUR 500 from the bank. In one Gibobs case, the user saw in their FEIN that Caixabank paid Gibobs EUR 800 for their deal. You pay nothing.
The main brokers and what to expect
iAhorro is one of the most widely known and works with a large number of banks. Initial response is generally fast. The most common complaint: after delivering the initial offers, follow-up tends to be passive. Some users describe the assigned manager as disengaged once the offers are on the table.
Gibobs gets consistently better reviews for personalised attention throughout the process. Multiple users cite it as the broker that stays most involved. It works with Caixabank among others and has achieved rates of 2.2% with payslip domiciliation only, when the same bank was asking for 2.7% with full conditions in-branch.
Trioteca gets mixed reviews: some describe it as giving the most thorough advice and staying close, others report days of silence. One user summarises it well: "Trioteca was slightly more involved than the rest, but brokers are only the first step — you still manage the counteroffers yourself with the bank manager they assign you."
Bayteca offers a free option if your profile qualifies and a paid premium service for more complex operations. It's well regarded in specialist online mortgage communities and has managers with strong follow-through. It's registered and authorised by the Banco de Espana.
Idealista (their mortgage service) gets consistently the worst reviews: "slow", "useless", "they put you in touch and then completely forget about you."
The expediente problem: read this before you do anything
This has real consequences, and banks count on you not knowing about it.
When a broker sends your details to a bank, the bank opens a case (expediente) in your name. If you then try to go to that bank yourself, they'll tell you there's already an open case and they can't give you a separate offer.
The same applies in reverse: if you already walked into a branch and the manager opened a case, the broker can no longer work that bank for you.
The practical advice that comes up repeatedly in forums: always start with a broker, don't go to branches first. Cancelling a broker's expediente is straightforward; getting a branch manager to close theirs is harder because it's not in their interest to let you go.
If you already have an open case at a bank, request a formal written cancellation before the broker can act there.
Can you use multiple brokers at once?
Yes, with one condition: make sure they don't send your data to the same bank. Each broker has agreements with different lenders, so you can split the field — one broker for some banks, another for the ones the first doesn't cover. Several users do exactly this, dividing banks between iAhorro and Gibobs, for example, and confirming upfront which banks each will contact.
Free brokers vs. paid brokers
Free brokers (iAhorro, Trioteca, Gibobs, Bayteca's free tier) only get paid if you sign, and the bank pays them. Their limitation is that they work primarily with standard profiles: if you need more than 90% financing, have an atypical employment situation, or the deal is complicated, they may decline to take you on.
Paid brokers — several operate in private online mortgage communities — can handle harder cases: self-employed borrowers, 100% financing, self-build projects, investment properties. Fees typically range from EUR 1,500 to EUR 5,000 depending on the deal.
What a broker can't do
A broker isn't magic. If your profile isn't attractive to a bank, the broker doesn't change that reality. As one person with banking experience put it: "The power a client has to negotiate depends on their profile. A broker has the same power as that client. If the bank doesn't want to move, the broker can't do anything — it all depends on which bank manager you get and how much effort they want to put in."
A good broker saves you time, gives you access to volume-rate conditions you wouldn't get at a branch, and advises you on what to ask for. A bad one just passes your data to the banks and waits to see if any of them bite so they can collect their commission.
