Yes, via a company purchase of the property from yourself, but it triggers SDLT (including surcharges), capital gains tax, and legal costs. Many landlords use incorporation relief or s.162 incorporation only in specific circumstances — take tax advice first. Lenders treat it as a new purchase or remortgage into the company. The transfer must stack up on overall tax and fees; it is not automatically cheaper than retaining personal ownership.
Limited company HMO mortgages typically require a minimum deposit of 25-30% of the property value, meaning the maximum loan-to-value available is 70-75%. While this mirrors the requirement for personal HMO mortgages, there are some differences in practice. Newly incorporated companies with no trading history or no track record of holding property will generally be required to provide a 30-35% deposit, as lenders view a brand-new SPV as higher risk than an established company. Experienced property investors who have been borrowing through a limited company structure for several years, and whose company demonstrates strong rental income, may access 75% LTV (25% deposit) from a wider range of lenders. The deposit must come from legitimate business funds — either equity already in the company from previous transactions, or a director's loan injection from personal funds. Gifted deposits are generally not accepted for limited company purchases, and lenders will require a clear audit trail of where the deposit originated. As an illustration: purchasing an HMO worth £400,000 through a limited company at 75% LTV would require a £100,000 deposit and a £300,000 mortgage. At 70% LTV, the deposit rises to £120,000. It is also worth noting that Stamp Duty Land Tax (SDLT) is payable at the higher 3% surcharge rate on top of standard rates for company purchases in England, which adds a further significant upfront cost — on a £400,000 purchase this surcharge alone would be approximately £12,000. Budget for this alongside the deposit when assessing total funds required.
Limited company HMO mortgage rates are typically 0.5-1.5% per annum higher than equivalent personal HMO mortgages. This premium reflects the additional risk and administrative complexity for lenders when lending to a corporate entity: the company structure adds a layer of separation between the lender and the underlying asset, personal creditworthiness assessments are more complex, and the legal processes involved in enforcement in the event of a default are more involved. As a practical illustration: if a personal HMO mortgage for an equivalent property is available at 5.5% on a five-year fix, a limited company mortgage for the same property and LTV might be available at 6.0-6.5%. On a £300,000 mortgage, that 0.5% premium adds £125 per month (£1,500 per year) in additional interest costs; a 1% premium adds £250 per month (£3,000 per year). This cost differential is a key consideration in the personal-versus-company ownership decision: for a higher-rate taxpayer, the tax savings from operating through a limited company (via full mortgage interest deductibility against corporation tax) can significantly outweigh the higher mortgage rate premium. However, for a basic rate taxpayer with a small portfolio, the rate premium may wipe out any tax advantage. The number of lenders active in the limited company HMO space has grown considerably since 2017, increasing competition and narrowing the rate gap compared to a few years ago. A specialist broker will be able to run a side-by-side comparison of personal versus limited company rates from current live products, which is the most reliable way to quantify the actual cost difference for your specific situation.
Lenders typically want a UK-registered Ltd/SPV, directors with acceptable credit, demonstrable rental income on the HMO, valid licensing, and LTV up to 75% (sometimes 80% for strong cases). New SPVs are accepted by many specialists without trading history if directors have landlord experience. Personal guarantees are common. Properties must meet minimum room sizes and HMO standards; some lenders cap number of rooms or require experienced management.
A commercial HMO mortgage is for properties classified as commercial, typically larger HMOs or those with specific property types. These mortgages have higher rates and stricter criteria than residential HMO mortgages.
Commercial HMO finance uses commercial underwriting — valuers assess business use, floor area, and commercial comparables as well as room rents. Loan terms can run to 20–25 years on some products, and fees are higher. Planning use class (C4 sui generis or mixed) matters more than on standard residential HMOs. Lenders may require evidence of commercial conversion feasibility and higher deposits (often 30–35%).
Deposits are typically 30–35% for commercial-class HMO properties (65–70% LTV), higher than standard residential HMOs. Strong rental contracts and experienced sponsors may access 70% LTV in niche cases. On a £800,000 commercial conversion target, expect £240,000–£280,000 equity plus fees. Lenders price in void risk, conversion cost overrun, and commercial valuation uncertainty.
Commercial HMO rates often sit around 5.5%–8% depending on LTV, location, and whether the asset is income-producing or conversion-led. They are usually 0.5–1.5% above standard HMO products because of valuation complexity and smaller lender panel. Fixed periods of 2–5 years are available from specialist banks and non-bank lenders. Always compare all-in cost including arrangement fees and valuation charges.
Yes, if planning permission and building regulations allow change of use to HMO (often sui generis C4 or mixed use). Offices, shops, and other commercial classes may need prior approval or full planning. The mortgage must be a commercial or specialist conversion product — standard residential HMO lenders may decline pre-conversion. Factor in longer void periods during works and higher build costs than a simple refurbishment.
You need a viable conversion or existing HMO business plan, acceptable credit, relevant experience (or a strong project team), planning route identified, and sufficient equity. Lenders cap LTV on purchase and on GDV separately on development-style deals. Minimum room sizes and fire standards still apply post-conversion. Corporate borrowers need acceptable company structure and often personal guarantees.
You usually need planning permission for change of use from commercial to HMO (sui generis C4), unless permitted development rights apply in your area (check the local plan — many cities restrict PD for HMO). Article 4 directions can remove PD rights entirely. You will also need building regulations approval for fire safety, means of escape, and amenity standards. Pre-application advice from the council is worthwhile before purchasing.
Planning can take 8–13 weeks if a full application is required; building works often run 3–6 months depending on scale. Total project timeline from purchase to licensed letting is commonly 6–12 months. Bridging finance is frequently used for the purchase and works phase, then refinance onto a term HMO mortgage once licensed and let. Build contingency time into your bridge term.
Costs vary widely: planning and professional fees £5,000–£15,000; build costs £800–£1,500 per sq m for moderate conversions; fire safety and compliance £10,000–£40,000+. On a 300 sq m former office, a £250,000–£400,000 build budget is not unusual before furnishings. Include SDLT, legal fees, and finance costs. A detailed schedule of works and QS report helps lenders and investors benchmark spend.
Some commercial or refurbishment products allow purchase plus works in one facility, typically via staged drawdowns up to 65–70% of total costs or GDV. Pure commercial term loans on day one usually fund only the existing asset, not future works — you may need bridging or development finance first. Your broker can structure purchase bridge → works tranches → exit refinance to minimise duplicate fees.
A portfolio HMO mortgage is designed for landlords with multiple HMO properties, offering more flexible terms. These mortgages typically have lower rates and higher borrowing limits for experienced investors.
