HMO vs Buy to Let: Which Makes More Sense in London Right Now ?
The question comes up constantly: should I buy an HMO or a standard buy-to-let ? The honest answer is that it depends entirely on who is asking. HMOs are not universally superior to standard BTL, and standard BTL is not a lazy default that sophisticated investors should dismiss. Each has a clear use case — and understanding which fits your situation is what matters.
The Numbers Head to Head
| Metric | Standard BTL | HMO (5-6 bed) |
|---|---|---|
| Typical gross yield (London) | 4-5.5% | 8-12% |
| Typical net yield | 2.5-4% | 5.5-8% |
| Income diversification | Single tenancy | 5-6 separate income streams |
| Void impact | Total income loss | Partial income loss only |
| Management complexity | Low-medium | High |
| Regulatory burden | Standard | Significant |
| Tenant turnover | Low | Higher |
| Capital growth | Full market rate | Investment value + market |
When HMO Makes More Sense
- You are willing to engage with the management complexity or pay for specialist management
- You are investing through a limited company where the tax treatment of expenses is more favourable
- You are building a portfolio and need higher yields to service debt and generate retained profit
- You have the capital for a proper refurbishment and compliance costs from the outset
- You are acquiring in outer London or the Home Counties where entry prices are lower but demand is strong
When Standard BTL Makes More Sense
- You are building a pension-replacement asset that requires minimal hands-on management
- You are investing in prime central London where residential capital growth is the primary driver
- You do not have the bandwidth to manage licences, compliance, and higher tenant turnover
- Your exit strategy requires broad buyer appeal — standard BTL properties sell to both investors and owner-occupiers
- You are investing in an Article 4 area where HMO conversion is restricted
The Tax Dimension
Since Section 24 phased in, mortgage interest relief for residential property is restricted for higher-rate taxpayers holding personally. This has significantly compressed standard BTL returns for many investors.
HMOs held in a limited company are unaffected by Section 24 — the company deducts mortgage interest as a business expense in full. For higher-rate taxpayers, this makes the case for limited company HMO investing considerably stronger than personal-name standard BTL.
The Management Question
HMOs generate more management activity than standard BTL by definition — more tenants, more rooms, more maintenance, more compliance. Self-managing an HMO is viable but demanding. Specialist HMO management agents charge 12-18% of gross rent, which must be factored into your net yield calculation from the outset.
