Rent to Rent Risks:
What Can Go Wrong and How to Manage It

Financial Risks

Void periods exceeding projections — If rooms remain empty longer than your model assumes, your income drops while costs continue. Mitigation: run your deal analysis at 75–80% occupancy, never 95–100%. If the deal only works at high occupancy, do not take it on.

Rising utility costs — Energy prices fluctuate. A deal that worked at 2022 energy prices may not work at 2024 prices. Mitigation: model utility costs conservatively, include a buffer, and review tariffs annually. For more detail, see how VAT applies to rent to rent.

Setup cost overruns — Refurbishment frequently costs more than planned. Mitigation: get 3 contractor quotes, add a 20% contingency to every budget, and never start a refurbishment without a fixed-price agreement where possible.

Locked into an unprofitable contract — If the deal underperforms, you are still obligated to pay the landlord each month. Mitigation: always negotiate a mutual break clause (typically from month 18) as a contractual safety net. For more detail, see how break clauses work in rent to rent.

Legal and Compliance Risks

Operating without proper consent — If your contract does not explicitly permit subletting, or if the landlord’s mortgage prohibits it, your entire operation may be unlawful. Mitigation: always have a solicitor-reviewed Company Let Agreement with explicit subletting permission; always ask the landlord to confirm mortgage consent in writing. For more detail, see how to get consent to sublet.

HMO licensing failures — Operating an unlicensed HMO exposes you to fines of up to £30,000 and an unlimited rent repayment order. Mitigation: check the licensing position with the council before signing every deal; submit your licence application before occupation.

Article 4 breaches — In Article 4 areas, converting a C3 dwelling to C4 HMO use without planning permission is unlawful. Mitigation: verify the planning position with the local authority before committing to any deal in a new area. For more detail, see planning permission requirements.

Operational and Relationship Risks

Landlord sells the property — A landlord who sells mid-contract triggers early termination. Mitigation: include a clause requiring the landlord to give 6 months notice if they intend to sell, and explore whether you could facilitate a sale to a buy-to-let investor who would honour your contract.

Difficult tenants — Bad tenants can cause damage, arrears, and void periods as you go through the eviction process. Mitigation: robust tenant referencing for every occupant; never take on a tenant you have not properly screened.

Contractor failure — An unreliable maintenance contractor can cause tenant complaints, legal notices, and reputational damage. Mitigation: build a network of 2–3 reliable contractors for each trade; never rely on a single point of failure.
