Rate discounts and cross-selling: what banks ask for and how to evaluate it
No Spanish bank gives you its best rate for free. They sell it to you. The system works like this: they show you a high base rate (typically 2.5% to 3.5%), then lower it if you buy their insurance, deposit your salary, and sign up for products that pad their margins. Those reductions are called bonificaciones (rate discounts). The products you must hold to get them are called vinculaciones (tied products). The bank's business is not just interest — it is everything they sell you around it.
The most common tied products
These appear in virtually every mortgage offer on the market:
- Payroll domiciliation (nómina): discounts between 0.25% and 0.75% depending on the bank. The only tied product that costs you nothing extra. CaixaBank typically offers 0.35% just for direct deposit; Kutxabank goes up to 0.50%.
- Home insurance: typically 0.10–0.20% discount. The bank's own policy usually costs €40–80/month, significantly more expensive than the open market. The bank profits twice: on the interest and on the premium.
- Life insurance: 0.20–0.35% discount. The most expensive tied product. It can be a single premium (paid once upfront, often €2,000–5,000 per borrower) or annual (roughly €150–300/year per borrower, but the price rises with age). A market-rate life insurance policy is consistently cheaper than the bank's.
- Credit card with minimum spend: usually 0.10% for spending more than €1,200/year on the bank's card.
- Health insurance: 0.10% at some banks, particularly Kutxabank.
- Investment funds or pension plans: some banks including Kutxabank and Cajamar discount 0.10–0.20% for minimum annual contributions.
- Security alarm (Securitas Direct): appears in CaixaBank offers at 0.15%. Multiple users describe it as a straightforward rip-off at roughly €52/month given what it actually delivers.
What people with years of experience on these tied products say
The forum debate is not whether to accept tied products, but how to calculate the real cost of each tied product against the interest saving it generates.
A real example: CaixaBank offered a fixed rate of 2.9% unbonified and 1.9% bonified (a 1-point discount). That discount required payroll domiciliation (0.35%), life insurance (0.35%), home insurance (0.15%) and a security alarm (0.15%). The cost of those products with the bank: approximately €80/month for life insurance and €40/month for home insurance. On a €150,000 mortgage the 1% saving on the interest rate is significant — but twelve years of overpriced insurance substantially erodes that saving.
The recommendation that recurs constantly in the forums: compare the net TIN after removing tied products, not the bonified headline rate. Between two banks offering 2% bonified, the one starting from 2.5% unbonified is better than the one starting from 3%: if you ever lose a tied product — job change, bank raising insurance prices — the penalty is smaller.
The strategy of cancelling insurance after signing
A common practice: take out the tied insurance products to get the bonified rate at signing, then cancel them shortly afterwards.
Spanish law makes this possible. It distinguishes between obligation and bonus: the bank cannot force you to keep an insurance policy indefinitely — it can only stop applying the discount if you cancel it. With Ibercaja's mixed mortgage, for example, the fixed-tranche rate does not change if you cancel the insurance policies — the bonifications only affect the variable tranche.
The cancellation procedure: a registered letter or burofax to the insurer (for Ibercaja, Ibervida for life insurance and Caser for home insurance) with a copy of your ID and a written notice of withdrawal. Multiple experienced users say the right moment is immediately after signing at the notary, once the mandatory reflection period has ended.
Important caveats:
- On purely fixed-rate mortgages, cancelling the insurance may push up your rate for the entire remaining life of the loan.
- If the bank reviews your tied products annually (checking what you hold each 12-month period), cancelling a few months in can spike your rate in the following year.
- Read the FEIN carefully before signing: it must state the unbonified rate, the bonified rate, and exactly which products are required and for how long.
What banks cannot legally do
Banks cannot require you to take out insurance as a condition for granting the mortgage. What they can do is offer a higher rate if you do not. In practice, some bank staff deliberately blur the line between "no insurance means no mortgage" and "no insurance means a higher rate." The difference matters and is regulated.
If a manager tells you that certain products are compulsory, ask to have that stated in writing in the FEIN. If it does not appear there as a contractual obligation, it is not one. Banks trade on your ignorance.
How to evaluate an offer with tied products
The most direct method is to calculate the annual cost of each tied product and compare it to the interest saving it generates:
- If the bank's life insurance costs €800/year and you could get equivalent cover in the market for €300/year, the extra cost is €500/year.
- If that insurance discounts 0.25% on a €200,000 mortgage, the annual interest saving is approximately €500.
- In that case they break even. If the bank's insurance costs more than €500/year extra, the tied product is not worth it.
Run this comparison for each product separately, not as a bundle. Payroll domiciliation almost always makes sense. Home insurance, sometimes. Life insurance through the bank, almost never at normal market conditions.
One final observation from the forums: a low bonified rate that starts from a high base is worse than a slightly higher bonified rate that starts from a low base. Freedom from tied products has a long-term value — 30 years is a long time to be locked into a bank's overpriced insurance.
