Do you take over the developer's mortgage by subrogación, or redeem it?
Almost every Spanish developer finances the project through a bank. That mortgage is divided across the individual units — and at handover the buyer faces a choice that is often presented as a foregone conclusion.

In short
Am I bound to the developer's bank?
The developer has a loan for the project. At handover the buyer may take over the share attributable to their unit.
Taking over the developer's mortgage is an option, not a condition
No. You may choose any Spanish bank freely. Subrogación is an option, not a condition of the purchase.
Subrogación saves some costs — the sums decide
Partly — certain costs of creating a new mortgage fall away. Whether that outweighs a possible disadvantage in the terms can only be calculated case by case.
Do I have to take over the developer's mortgage?
No. Almost every Spanish developer funds a project through a bank and divides that mortgage across the individual units at completion. At handover you may take on the share attributed to your unit — the subrogación — or bring your own financing. There is no obligation to take it over, however it may be presented during the sales conversation. Taking it over saves part of the notary and registry costs and is quicker; in exchange you inherit a rate, a term and conditions the developer negotiated for itself, not for you. Your own mortgage involves more formalities but is negotiable — and for non-residents it is the normal route anyway, since the customary ceiling sits at around 70 per cent of the tasación and the developer's structure rarely fits that frame. Run both options through the numbers before you go to the notary, not while you are sitting there.
The developer loan and its division
Spanish banks have a dedicated model for residential development: a mortgage-secured loan to the developer that funds construction and sometimes the land purchase. Before handover the developer divides the building into individual units by notarial deed (división horizontal), and bank and developer allocate liability across those units.
At the transfer of ownership the buyer can then decide: take over the mortgage share attributable to their unit (subrogate) — or redeem it and bring their own financing.
You are not bound
Subrogación is readily presented as the simple, fast route: no fresh valuation, less paperwork, the date holds. Often that is even true. What gets lost: there is no obligation to take it. The buyer may approach any Spanish bank.
Whether taking over is advantageous depends on the terms of the developer's loan — and those were negotiated for the developer, not for you. Remaining term, rate fixing, early-repayment rights, tied products: all of that must be checked before signing out of convenience.
The comparison is the actual work — and precisely where a broker who knows both sides earns their keep.
Which route when
- Consider subrogación where the date is tight, a valuation would take extra work, or the developer loan's terms are objectively good.
- Your own bank where your credit profile is stronger than the developer loan assumes, where you need a different term, or where products you do not want are tied to the takeover.
- Always check: non-residents face tighter lending limits than residents in practice — sometimes that alone answers the question.
