Guaranteed Rent (Rent to Rent): What It Is and Why It Benefits the Owner

"Getting paid every month even if the flat is empty" sounds too good to be true. But that is exactly what the guaranteed rent model — also known as rent to rent — offers. Let us explain how it really works, with no small print.
What guaranteed rent is
A management company rents your whole flat under a long-term contract and pays you a fixed rent every month. In return, that company sublets the flat (usually by rooms) and keeps the difference, taking on the management and the occupancy risk.
Put simply: you sign with a solvent company, not a private tenant, and you get paid come rain or shine.
What the contract looks like
It is a lease between you (the owner) and the management company, with express authorisation to sublet. It usually includes:
- A fixed, guaranteed monthly rent.
- An agreed term (typically 3–5 years).
- The company takes care of ordinary maintenance and of returning the flat in good condition.
What you do and do not collect
You collect a fixed, predictable rent, all 12 months, whether the flat is full or empty. You do not collect the theoretical maximum you would get managing it by rooms yourself, because that "extra" is precisely what pays for the company's work and risk. It is the fair trade-off: you swap your income ceiling for zero management and zero risk of non-payment.
The advantages for you
- Guaranteed income even when rooms are empty.
- Zero arrears: your counterpart is a company, not a private individual.
- Zero management: forget about tenants, bills, breakdowns and cleanings.
- Property upkeep: it is looked after and handed back in good condition.
- Tax and legal peace of mind: a single, clear contract.
The risks (and how they are mitigated)
No model is magic. What matters is who you sign with:
- The company's solvency: check its track record and the flats it manages.
- Hand-back condition: make sure the contract details the inventory and conditions.
- Controlled subletting: that the company selects tenants well.
With a serious company, these points are covered by contract.
Which owner does it make sense for?
Guaranteed rent fits especially well if:
- You live far from the flat or have no time to manage it.
- You want stable, predictable income for your finances.
- You worry about arrears or squatting.
- You prefer peace of mind over squeezing out the last euro.
In short
Guaranteed rent is not for someone who wants the absolute maximum at the cost of managing everything. It is for the owner who values sleeping easy and getting paid a fixed amount. If that is your priority, it is probably the best model out there today.
