HMO Yields in London 2026: Where to Buy and What to Expect
The HMO yield premium over conventional buy-to-let remains compelling in 2026, but it is not uniform across London. Entry prices, local demand profiles, and licensing costs vary significantly by borough — and understanding those differences is what separates investors who build genuinely profitable portfolios from those who learn expensive lessons.
These figures are drawn from market data and transactions we have handled or advised on through London Property Brokerage Limited. They represent realistic ranges, not best-case projections.
Gross vs Net Yield — The HMO Reality
HMO gross yields are genuinely higher than standard BTL. But the cost structure is also higher, and failing to account for it leads to disappointment.
| Cost Item | Standard BTL | HMO |
|---|---|---|
| Management fee | 8-10% | 12-18% |
| Licensing | — | £100-£300 p.a. amortised |
| Bills (included) | — | £150-£400 p.a. per room |
| Maintenance | 1-1.5% of value | 2-3% of value |
| Void rate | 3-5% | 5-10% (per room) |
| Insurance | Standard | +30-50% premium |
After these costs, a property yielding 10% gross typically nets 6.5-8%. Still substantially above conventional BTL, but the gap narrows considerably from the headline figure.

Yield Calculation: A Worked Example
6-bed HMO, Slough SL1:
- Purchase price: £440,000
- Refurbishment to HMO standard: £35,000
- Total invested: £475,000
- Room rents: 6 rooms at £750/month = £54,000 p.a. gross
- Gross yield on total invested: 11.4%
- Management (15%): £8,100
- Bills estimate: £7,200
- Maintenance: £9,500
- Insurance, licence, misc: £2,800
- Total costs: £27,600
- Net income: £26,400
- Net yield: 5.6%
That 5.6% net yield on a property with capital growth potential and portfolio scalability remains an attractive proposition — particularly when compared to a standard BTL net yield of 2.5-3.5% on a similar capital outlay in the same area.
The real value of HMO is not just the yield premium — it is the diversification of rental income. Six rooms means six revenue streams. One void does not stop your mortgage being paid.
Financing in 2026
HMO mortgage rates remain elevated relative to pre-2022 levels but have stabilised. Key features of the 2026 HMO finance market:
- Most lenders require 25-30% deposit for standard HMOs; up to 35% for larger or unusual properties
- Stress testing at 125-145% of the monthly interest payment from rental income
- Limited company (SPV) purchasing has become dominant for new HMO acquisitions due to mortgage interest relief
- Some specialist lenders will lend on property value post-refurbishment (bridging then refinance)
- First-time HMO buyers may face restrictions — some lenders require 1-2 years' landlord experience
