Renting vs buying on the coast: the honest maths.
If you are Irish and renting on the Costa del Sol, you have probably had the conversation already. The lease renewal lands, the number has gone up again, and someone says what everyone is thinking: we should just buy something.
Sometimes that instinct is right. Sometimes it is the rent talking. Here is how to tell the difference.
The honest case for staying a renter
Rent is not dead money. Rent buys flexibility, and flexibility has real value when your plans are genuinely unsettled. If you are not sure the coast is permanent, if your work situation could pull you home, if you have been here less than a year and have not yet lived through an August or a February in your town, keep renting. A wrong purchase costs far more than a year of rent, because buying and selling in Spain carries roughly 9 to 10% in costs on the way in and more on the way out. Property here rewards people who stay put.
The case for buying, which gets stronger the longer you stay
Now the other side. Every year you rent, you hand over twelve payments that build nothing, while carrying the risk that the landlord sells, moves back in, or puts the rent up again. Coastal rents have risen hard in recent years and long-term rental stock keeps shrinking as owners switch to holiday lets. Renters feel that squeeze annually. Owners do not.
And as a resident, the buying side is tilted in your favour in ways it was not when you first arrived. Spanish banks typically lend residents up to 80% rather than the 60 to 70% offered to non-residents. Your NIE, padrón and bank account already exist. And you can house-hunt slowly, in person, in every season, which is a luxury no buyer flying in from Dublin ever gets. The full list is in our guide to buying as an Irish resident.
A worked comparison
Take a two-bed renting at €1,400 a month. That is €16,800 a year. Buying its equivalent at €280,000 with a resident mortgage at 80% means finding roughly €56,000 of deposit plus about €26,000 in purchase costs. Call it €82,000 down, and the mortgage repayment on the remaining €224,000 will, at current rates, typically land in the same territory as the rent or below it. Run your own numbers in the cost calculator with real asking prices from your own street.
The question is not whether the monthly figures match. It is whether you will stay long enough for the up-front costs to earn their keep. The rough rule: under three years, renting usually wins. Past five, buying usually has. In between, it depends on you, and anyone who gives you a harder answer than that is selling something.
The trap to avoid
Do not buy the apartment you are renting just because it is familiar and the landlord offers. Familiar is not the same as right. Compare it against the whole market first, the same way you would compare any property, because the discount for skipping that step is usually imaginary.
