Rentero
Spanish lease law, applied
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Four free engines read your contract against the Tenancies Act: the real end dates, the ceiling on an increase, the deposit rules and the rent cap.
Rentero applies the Spanish Urban Tenancies Act to the contracts you actually signed, and then keeps the books.
Every rent tracker records what you charged. Rentero starts a step earlier: it reads your contract against Act 29/1994, works out the dates and limits the law imposes whatever the paper says, and cites the article behind each answer. That part is free, on every property, with no subscription.
FOUR THINGS THE LAW DECIDES, NOT YOUR CONTRACT
1 · The end date is not the one you wrote (arts. 9, 10 and 11)
A twelve-month tenancy does not end in twelve months. It extends year by year up to five — seven if the landlord is a company — then up to three more unless someone gives notice in time. Rentero shows all four: what you agreed, the statutory minimum, the longest possible end, and the day you must notify by. That day goes in your calendar, because missing it extends the tenancy for you.
2 · The increase has a ceiling your contract does not mention (art. 18)
Since 2022 the cap has changed three times: the Competitiveness Guarantee Index, itself capped at 2%, from 31 March 2022 to the end of 2023; a flat 3% through 2024; and the reference index the INE publishes from 2025. Rentero picks the rule in force on your anniversary, applies the lower of that cap and your agreed index, and reminds you the new rent is only payable from the month after the tenant gets the notice in writing.
3 · The deposit is fixed by statute, not by agreement (art. 36)
One month's rent for a home, two for any other use. Extra guarantees capped at two months more. Frozen for the first five or seven years. And one month after the keys come back, whatever you still hold owes the tenant statutory interest — counted here day by day.
4 · A declared stressed area caps a new contract (arts. 17.6 and 17.7)
No more than the previous tenant paid once updated, plus ten per cent in four listed cases and no others. If you are a large holder under art. 3.k) of Act 12/2023, the ceiling is the official reference index instead.
THE AUDIT
One tap reads every contract and sorts what it finds into what is wrong, what needs a decision, and what is worth knowing. Each finding names its article, drops its deadline into your calendar, and quotes in full the passage of the Act it came from — so you read the law inside the app instead of taking our word for it.
WHAT RENTERO WILL NOT PRETEND TO KNOW
Whether your street is in a declared stressed area, and what the reference system gives for your flat, are published area by area and change, so Rentero asks and links to the government system. It is not a lawyer and gives no advice: it applies the text and shows you the text.
AND THE LEDGER, TOO
• Rent month by month, where a partial transfer is never shown as settled
• Expenses by category, with the receipt photographed and attached
• Real yield, and the year's deductible expenses by concept
• OCR scanning, inspections, inventories and letters
• Every figure shows its formula and its inputs on the same screen
No account, no server, no analytics, no ads, and it works with no signal.
FREE, AND PREMIUM
The four legal engines, the audit and the sources are free on every property and will stay that way. One property and the basic ledger are free too. Premium unlocks your whole portfolio and the heavier tools: tax report, yield comparison, estimated value, scanning and bank import.
Rentero Premium is an auto-renewable subscription: US$19.99 per month or US$149.99 per year in the United States, and the equivalent in your currency elsewhere, shown before you confirm. Payment is charged to your Apple Account on confirmation. It renews unless you cancel at least 24 hours before the period ends; cancel any time in your Apple Account settings.
Rentero is not a law firm or a tax adviser and files nothing on your behalf.
