For private owners renting out flats or commercial units long term in Spain. Not for holiday lets.
Renting out in Spain,
without the paperwork panic.
You don't have to understand the Spanish system. Soycasero does. Fianza, prórroga, IPC, Modelo 210: the app knows which deadline applies to your contract and tells you before it matters, in English.
When the rent is late or something needs doing, it drafts the message for you. In Spanish for your tenant, explained in English for you. You decide whether it goes.
No commitment, no card details. Just your email.

How it works
Three steps. No forms, no spreadsheets.
Nothing new to learn. If you have the paperwork, you can start.
- 1
Upload whatever you have
Contracts, extensions, IDs, payslips, receipts. Whatever sits in a folder or on your phone, in Spanish or not. The app reads it and pulls out the data. No typing.
- 2
Soycasero sorts it out
Each property with its contract, tenant, utilities and dates. The app works out due dates, CPI increases, extensions and deposits under Spanish law (LAU), so you don't have to look any of it up.
- 3
You decide what to send
Late payment, extension due, CPI increase, deposit to return: the app prepares the message and tells you why. You read it, approve or change it, and send by email or WhatsApp.
Mira por dentro
Mira cómo trabaja Soycasero
Sube los papeles, la app organiza, tú decides cuándo enviar al inquilino.
El email del impago, ya escrito
Pasan 5 días sin pago y la app te prepara el texto: correcto, firme y con la LAU detrás. Email o WhatsApp, tú decides cuándo enviarlo. Nunca se manda nada solo.
La actualización de renta, calculada
IPC o IRAV con el tope legal aplicado (Ley 12/2023). Tú confirmas, el inquilino lo recibe. Sin calcular nada a mano.
Te avisa cuando hay que actuar
Fianzas, prórrogas, impagos, IPC: cada plazo aparece como un aviso claro con su botón. Nada que recordar de memoria.
Sube los papeles. Nosotros hacemos el resto
Contratos, DNIs, nóminas, facturas: la IA lee y organiza todo. Tú revisas y confirmas.
Acta de entrega lista para firmar
Lecturas de contadores, llaves, inventario, fotos del estado. Un PDF que sirve como prueba si en el futuro hay dudas.
Y todo también en el móvil
Who it's for
Private owners. Not letting agencies.
You bought a place in Spain
You own a flat on the coast or in the city and rent it out long term. The rules are Spanish, the letters are Spanish, and you are not always in the country. The app keeps track for you.
You're not resident here
Modelo 210 every quarter, no local gestor on call, and deadlines that don't care where you live. Soycasero tells you what is due and when, and prepares what you need.
You look after family property
You handle a flat for your parents or a relative, often from abroad. Rent, contracts, IBI, utilities. It all lands on you, and we help you not miss anything.
What it does for you
Everything you have to watch. Watched.
When the rent is late
If the agreed day passes and no payment is logged, we draft the reminder for your tenant in correct Spanish, with the usual 24 hours' grace. You just press send.
IPC or IRAV
The rent increase index depends on your contract date. The app knows which one applies, warns you a month ahead with the new figure, and respects the legal cap under Ley 12/2023.
Prórroga (extension)
Four months before the contract ends we prepare the notice to your tenant. If there's no reply, we remind you to send the burofax, the recorded letter that counts as proof in Spain.
Email or WhatsApp
Every draft with two buttons: email (leaves a record) or WhatsApp (how people actually talk here). Your call.
Handover record
Meter readings, inventory, photos of the condition. The app builds a PDF that works as evidence if there's a dispute later.
Calendar
Deposit, IBI, end of contract, CPI. One URL and it all shows up in your Apple or Google Calendar with native alerts.
