An 80 m² flat in Mollet is valued at €196,200. Rented at €721 a month, that generates €8,652 a year — so buying equals 22.7 years of rent.

It's the mirror image of yield: the more years, the more expensive buying is relative to renting. It doesn't include mortgage interest, purchase taxes, or renovation costs, all of which push the figure higher.

As a reference point, Spain's national average has historically moved between 15 and 25 years depending on the cycle.

Mollet is the 8th most expensive of the twelve municipalities in the area, and the 11th most expensive to rent. Where those two rankings don't match is where the opportunities tend to sit.

An 80 m² flat in Santa Perpètua de Mogoda is valued at €198,000, and its average rent is €745 a month — €8,940 a year. That works out to a gross yield of 4.5%.

Gross means before anything else: council tax (IBI), community fees, insurance, one-off building charges, income tax on the rent, and any months the flat sits empty. Net yield lands well below that.

It's the 8th most of the twelve municipalities in the area. Worth distrusting the shortcut of always going for the highest yield: high yield tends to travel with low prices, and low prices with weaker rental demand and higher turnover.

The figure is for comparing municipalities against each other, not for deciding on a purchase. A specific flat can yield well above or well below its city's average.

An 80 m² flat is valued at €202,100 in Granollers and €193,700 in Sabadell. The gap doesn't reach 5%.

Where they do split is on yield: Granollers returns 0.5 points less a year (4.9% versus 5.4%).

On rent, Granollers signs at €826 a month and Sabadell at €869: a €43 gap across 931 deposit-lodged contracts between the two.

Comparing towns is useful for orientation, not for pricing. Within a single town, the gap between neighbourhoods is usually bigger than the one between these two.

An 80 m² flat in Barcelona is valued at €374,000. Rented at €1,137 a month, that generates €13,644 a year — so buying equals 27.4 years of rent.

It's the mirror image of yield: the more years, the more expensive buying is relative to renting. It doesn't include mortgage interest, purchase taxes, or renovation costs, all of which push the figure higher.

As a reference point, Spain's national average has historically moved between 15 and 25 years depending on the cycle.

Barcelona is the 2nd most expensive of the twelve municipalities in the area, and the 2nd most expensive to rent. Where those two rankings don't match is where the opportunities tend to sit.
