Is this for you?

Two kinds of people
who need this operating system

Casas Creating Cashflow was built from ten years of managing Spanish property for foreign landlords. It is for the people who own the properties — and for the professionals who manage them.

Property owners

  • You own one or more properties in Spain
  • You live abroad or spend most of your time outside Spain
  • You self-manage and feel like you’re always one problem away from chaos
  • You want a system, not more improvisation
  • You’re tired of relying entirely on a manager you can’t verify

Property managers

  • You manage properties for others in Spain
  • Most of your process lives in your head — not on paper
  • You want to professionalise and scale without burning out
  • You’re interested in building a documented, repeatable system
  • You want to serve foreign landlords with more confidence

What you already know

The five things
nobody warned you about

Managing property in Spain is not complicated. Until it is. After eleven years on the ground in Madrid, here is what I see again and again:

1

You don’t do inspection reports.

So what? A crack in the shower screen. “It was already there,” says the tenant. You deduct it from the deposit. Fair enough. Until the burofax arrives. Prove it. You have nothing in writing. And you have to pay back the deposit. And pay the shower screen.

2

When was your rental contract last checked?

Rental rules in Spain have changed in recent years. A contract nobody has looked at since is probably out of date.

3

An index and a gut feeling.

Your long-term contracts follow an index. Your seasonal rentals follow your gut.

4

You are the system.

Everything runs through you: your phone, your experience, your contacts. It works. As long as you are there. Get sick or go away for a month, and everyone loses track. Because nobody else knows how it works.

5

A good impression.

You liked them at the viewing. They had a their payslips. Nobody called their previous landlord. Six months later, the first missed payment.

The programme

Nine modules.
One complete operating system.

Each module runs for two weeks. You receive the knowledge, complete the practical assignments, and apply it directly to your property. Every module includes a live Q&A and a dedicated Custom GPT to help you implement without getting stuck.

M0

Kickoff

Orientation, onboarding, and setting up your personal Casas Operating System. You will know exactly what you have, what’s missing, and where to start.

M1 Hat for the role Firefighter

Role: Firefighter — Crisis Management

How to handle the unexpected without losing money or control. From urgent repairs to legal disputes and sudden tenant problems.

M2 Hat for the role Negotiator

Role: Negotiator — Negotiation & Tenant Selection

A structured selection process and a negotiation framework. Stop choosing on gut feeling and start choosing with criteria that reduce your risk.

M3 Hat for the role Mediator

Role: Mediator — Conflict resolution

How to handle disagreements with tenants, neighbours and the community of owners before they escalate. Difficult conversations handled calmly, agreements in writing and fewer burofaxes.

M4 Hat for the role Lawyer

Role: Lawyer — Contracts & Legal Compliance

Spanish rental regulations, your contractual obligations, the clauses that protect you and what recent changes mean for you.

M5 Hat for the role Process Designer

Role: Process Designer — Building Your System

The complete inspection system: before, during and after the tenancy, with cleaning and maintenance checklists. What to document and how, so you and your tenant are on the same page.

M6 Hat for the role Inspector

Role: Inspector — Inspections That Protect You both

The complete inspection system: before, during and after the tenancy, with cleaning and maintenance checklists. What to document and how, so you and your tenant are on the same page.

M7 Hat for the role Business Manager

Role: Business Manager — Performance of the property

Your property, seen as a business. You grow your rental income, control costs and keep it in good condition, without empty months. The result: better returns, fewer problems and tenants who stay.

M8 Hat for the role Administrator

Role: Administrator — Running the Backend

All the paperwork, organised behind the scenes. Supplier contacts, invoicing and payment follow-up, archived contracts and documents, incident logs, home insurance and inspection reports. Everything in order, and easy to find.

Included

Two bonuses.
Both immediately useful.

These are not extras added to make the offer look larger. Both were built because they fill a specific gap that the modules alone cannot close.

Value 47 €

First Aid Maintenance for Tenants

The troubleshooting guide that helps your tenant before they call you. So you don’t get a message for every dripping tap. Fewer interruptions. More peace of mind.

Value 97 €

Furniture as Chess Pieces

The furnishing checklist for rental apartments in Spain. What to buy, what to skip, and where to place it so your apartment rents faster. Every piece with a purpose.

Your guide

Ten years in Madrid.
Starting with nothing written down.

I am Lilian Hermans. Dutch lawyer, Madrid resident for nearly twenty years, founder of Quilantro.

For ten years I managed property for foreign landlords in Spain. I knew exactly what to do, how to handle every situation, and when to escalate. None of it was written down. It lived entirely in my head.

When I hired my first employee in November 2024, I realised that was not a system. That was a single point of failure.

Casas Creating Cashflow is what I built to change that — first for myself, then for the owners and managers I work with. Not a course. A complete operating system for property in Spain.

From Quilantro clients

Ten years of
actual results.

The testimonials below come from Quilantro clients — property owners whose properties Lilian manages directly as a done-for-you service. They are not CCC participants. They are people who paid Quilantro to run the system for them.

CCC teaches you to run that same system yourself. Same knowledge. Same approach. Your own property, your own control.

Quilantro helps me navigate the real estate market from abroad without me having any sleepless nights.

A client from Denmark

Making contact with Lilian to manage our property is the best decision we’ve made so far about our property.

Clients from Australia

I can confidently say that I am completely relaxed knowing that my apartment is being well looked after.

Questions

What you might
want to know first.

Is English the language of the programme?

Yes. All modules, Q&A sessions, and written materials are in English. This makes the programme accessible to international property owners and managers regardless of their Spanish or Dutch language level.

Do I need to be based in Spain?

No. The programme is specifically designed for people who manage Spanish property without being physically present full time. The entire operating system works remotely.

What if I already have a property manager?

Then this is still for you. Understanding the system your manager should be following is the only way to verify they are actually doing their job. Many owners discover gaps only after something goes wrong.

Is this a course or a live programme?

Both. You receive structured module content and assignments, but the programme runs live with a fixed start date and live Q&A sessions. You are not working through pre-recorded videos in isolation — you are building your operating system in real time.

What happens after 1 January 2027? Will the price change?

Yes. The Founding Member rate of 247 € applies to this round only. Round two will be priced at the regular rate of 997 €. There are 5 places in this round and no exceptions once they are filled.

I have a question not answered here.

Send it to info@quilantro.com. I answer personally and usually within one working day.

Ready
