Rent to rent, usually shortened to R2R, is a strategy where you rent a property from its owner and then let it out to others, keeping the difference between what you pay the owner and what you collect. You do not own the building, and you often put down little or no deposit of your own, which is why it is marketed as a low-capital way into property. It is also one of the easiest strategies to get wrong, because the consents and licences that make it legal are the parts most often skipped. Here is how it actually works.
What rent to rent is
The idea is simple. You take on a property, you improve how it earns, and you keep the margin. Most R2R deals do this in one of two ways. Either you rent a family house and let it room by room as a house in multiple occupation (HMO), so five rooms at, say, £550 each bring in far more than a single family tenancy would. Or you run it as serviced accommodation, letting it night by night to short-stay guests through booking platforms.
Both routes rely on the same bet: that you can generate more income from the property than the fixed amount you have agreed to pay the owner, and that the gap covers your costs and leaves a profit. The owner gets a hands-off, reliable rent. You take on the work, the risk and the reward.
The two common structures
There are two contract structures you will meet, and the difference between them matters a great deal.
A company let or commercial lease
Here you (usually through a limited company) are the tenant on a lease, and the lease permits you to sublet. The owner rents to your company, your company rents to the occupiers. You are running a subletting business, and the responsibilities of a landlord towards those occupiers sit with you.
A guaranteed-rent management agreement
Here you do not take a lease. You manage the property on the owner's behalf and guarantee them a fixed monthly rent whether or not the rooms are full. This looks like a letting-agent arrangement, but a poorly drafted "management agreement" that gives you exclusive control of the property can in law be a lease in disguise. Getting the contract wrong is one of the most common R2R traps, so both sides should have the agreement checked by a solicitor rather than relying on a template found online.
Is rent to rent legal?
Yes, rent to rent is legal when it is done properly. It becomes non-compliant, and sometimes a criminal offence, when the consents and rules that should sit underneath it are missing. Several things all have to line up.
The owner needs their mortgage lender's consent. Most buy-to-let mortgages only permit a standard tenancy with the occupier in direct occupation, not subletting or a company let, so an R2R deal can breach the mortgage terms unless the lender agrees. The owner also needs consent from the freeholder or under the terms of the lease if the property is leasehold, as many leases restrict subletting and short lets.
As the operator, you must hold the HMO licence in your own name or your company's name, and you must meet the standards that come with it. The government's guidance on the HMO licence sets out who needs one and what is expected. On top of that come the ordinary duties that apply to anyone letting a home: gas safety, electrical safety, fire precautions, deposit protection and keeping the property in repair, all covered in the government's overview of renting out a property.
Planning can also bite. In an area covered by an Article 4 direction, converting a family home into an HMO, or using it for short lets, can require planning permission that it would not need elsewhere. Skip any one of these and the deal can be legal on paper but unlawful in practice.
HMO licensing
Because so many R2R deals are HMOs, licensing sits at the centre of the strategy. Mandatory HMO licensing applies to any property let to five or more people who form two or more separate households and share facilities such as a kitchen or bathroom. Some councils go further with additional or selective licensing that catches smaller shared houses, so you have to check the rules for the specific local authority.
As the operator running the letting, you are the person who applies for and holds the licence, and you are responsible for meeting its conditions on room sizes, amenities and safety. Operating an HMO that should be licensed but is not is a criminal offence, and it exposes you to a rent repayment order, which can require you to pay back up to twelve months of rent. If you are sizing up an HMO deal, the HMO calculator helps you model the room income against the rent you would owe the owner.
What the Renters' Rights Act 2025 changes
The Renters' Rights Act 2025 reshapes the private rented sector, and its main provisions come into force from 1 May 2026. It matters for R2R in a few specific ways. The government's Renters' Rights Act overview is the primary reference for the detail.
First, the reforms end the old system of fixed terms and no-fault notices, so there is no longer an automatic right to vacant possession simply because an R2R agreement has reached its end date. If an occupier does not leave, the owner may find responsibility for regaining possession lands back with them once the arrangement between owner and operator ends.
Second, owner-landlords face greater liability where an operator breaches obligations, which makes the choice of a competent, properly insured operator more important than ever. Third, rent repayment orders continue to apply to offences such as running an unlicensed HMO. The Act sits alongside the wider abolition of Section 21, which we cover in what replaced Section 21, and the Section 8 notice period checker can help you work out the correct notice for a possession ground.
The margins are thinner than they look
The headline of R2R is the spread between the rent you pay and the rent you collect, but that spread is not your profit. Out of it come the bills you now cover (council tax, gas, electricity, water, broadband), void periods when rooms sit empty, cleaning and management, the cost of furnishing the property, the licence fee and ongoing safety certificates. A deal that looks like it clears £900 a month can quietly fall to a fraction of that once every cost is in.
Model it line by line before you commit, and stress-test it against a couple of empty rooms rather than a full house. If you are comparing R2R against buying and refinancing, the BRRR calculator lets you put the numbers side by side.
Is rent to rent for you?
Rent to rent rewards people who treat it as an operating business, not a passive investment. You need the temperament for tenant management, the diligence to get every consent and licence in place, and the honesty to walk away from a deal whose margin does not survive a realistic cost model. Done properly, with the right contract and the owner's lender and freeholder on board, it is a legitimate way to build income without owning the property. Done casually, it is a fast route to an unlicensed-HMO prosecution and a rent repayment order. The strategy is only as sound as the paperwork underneath it.
