Selling a rented flat in Zaragoza

Zaragoza rents hit a record €12.30/m2 in August. What the law says if you sell a flat with a tenant: first refusal, the lease and who buys it.

Renting a flat in Zaragoza has never been more expensive: according to idealista, the city ended August at €12.30 per square metre per month, 11.1% up on a year earlier and the highest figure in its series. If you own a rented flat and want to sell, you can do so with the tenant in place: the lease survives the sale, the buyer becomes the new landlord and, unless the contract says otherwise, the tenant has the right to buy it first at the same price.

Update (November 2026): since 8 October, Royal Decree-Law 29/2026 has been in force: the tenant can no longer waive the right of first refusal in the lease, and the right applies even if the flat is sold together with other properties. We explain it in this article. Before selling a rented flat, check the current rules with a lawyer or notary.

Rents in Zaragoza in September 2026

The latest figures all point the same way:

idealista (August): Zaragoza city stands at €12.30/m² a month, up 11.1% year on year and a record for the series, as reported by HoyAragón, which notes that renting now costs almost 50% more than five years ago. The Spanish average in idealista's report is €15.10/m², up 5.8%.
Fotocasa (August): rents in Aragón average €12.35/m², 11.4% higher than a year ago and 1.9% up on July, according to its index as covered by Aragón Digital. That makes Aragón the region with the third-highest annual rise, compared with 2.4% for Spain as a whole in Fotocasa's release.

Bear in mind these are advertised prices on property portals, not signed rents, and each portal has its own method. Even so, the picture is clear: demand for rentals in Zaragoza is strong and supply is tight.

Is Zaragoza a "stressed" rental area?

No. Spain's Housing Law lets regions declare "stressed" areas where rents can be capped, but the decision lies with each regional government. Aragón's government said in 2024 that it would not apply those rent controls, as El Español reported, and in 2026 towns such as Aínsa were still asking for the designation without success (Última Hora / Europa Press). So there is currently no stressed-area rent cap in Zaragoza, although the political debate continues.

Selling a tenanted flat: the legal basics

The key law is the Urban Leases Act (LAU). In short:

The sale does not end the lease. The buyer steps into your shoes as landlord (article 14) and must honour the tenancy, at least for the statutory minimum of five years (seven if the landlord is a company). Whether it binds the buyer beyond that depends on the contract and on whether it is registered at the Land Registry.
Right of first refusal (tanteo). Before selling, you must formally notify the tenant of your decision to sell, the price and the terms. They have 30 calendar days to buy on those same terms (article 25).
Right of redemption (retracto). If the tenant was not notified, or the flat was finally sold for less or on better terms than those notified, the tenant can step into the purchase within 30 calendar days of the buyer notifying them of the deed. The sale cannot be registered unless these notices are proven.
When these rights do not apply. If the tenant expressly waived them in the contract (article 25.8), you only have to give at least 30 days' notice of your intention to sell before completion. They also do not apply when the flat is sold together with all the landlord's other homes and premises in the same building.

Check your contract and speak to a lawyer or notary before marketing the flat: a mistake in the notices can delay the sale or even unwind it.

Investor or owner-occupier?

With a tenant in place, your natural buyer is an investor, who will look at the rent and the yield. According to idealista, the average gross rental yield in Spain fell to 6.5% in the second quarter of 2026, from 7.2% a year earlier, because sale prices are rising faster than rents (Europa Press via Infobae). Investors do that maths and usually offer less than someone buying a home to live in.

To reach owner-occupiers, who make up most of the demand, you will normally need to sell the flat empty. The usual routes are to wait until the lease ends, giving notice of non-renewal within the period the LAU sets, or to agree an early exit with the tenant in writing, sometimes with compensation. It is also worth offering the flat to the tenant first: they are often the most motivated buyer.

Sell now or keep renting?

With rents at record levels, holding on may look like the obvious choice. Weigh up:

Your real net return after council tax (IBI), community fees, insurance, repairs, empty periods and tax.
Your plans: if you need cash, for example when siblings share an inheritance or in a divorce, extending a tenancy can complicate the split.
Today's sale price: Zaragoza house prices are also high, and an empty, well-presented flat usually sells on better terms.

There is no single answer. The sensible step is to compare, with real numbers, what you would get selling today, empty or tenanted, against what the rental leaves you each year.
