What is an HMO?
A House in Multiple Occupation (HMO) is a property rented out by at least 3 people who are not from one 'household' (e.g., a family) but share facilities like the bathroom and kitchen. HMOs can deliver significantly higher yields than traditional buy-to-let properties because you're renting by the room rather than the entire property.
Typical HMO Yields
- • 8-15% gross yield (vs 4-6% BTL)
- • £200-500+ cashflow per room/month
- • Higher demand in university towns
Key Considerations
- • Licensing requirements (mandatory or additional)
- • Higher management intensity
- • Fire safety regulations
Types of HMO
Shared house for 3-4 unrelated tenants. May not require mandatory licensing but check your local council.
- ✓ Lower entry point
- ✓ Easier to manage
- ✓ Less regulation
Properties with 5+ tenants over 3+ storeys require mandatory licensing throughout England.
- ✓ Higher yields
- ✓ Scale economies
- ⚠ Mandatory licence required
Purpose-built or converted properties targeting students near universities. High demand, predictable cycles.
- ✓ Guaranteed demand near unis
- ✓ Parents often act as guarantors
- ⚠ Seasonal void periods
HMO Licensing & Compliance
Mandatory Licensing
Since October 2018, mandatory HMO licensing applies to properties with:
- 5 or more tenants from 2+ households
- Sharing facilities (kitchen, bathroom)
- Any number of storeys (previously 3+)
Fire Safety Requirements
- Fire doors on all rooms and kitchens
- Interlinked smoke/heat alarms
- Emergency lighting in corridors
- Fire blankets in kitchens
- Clear escape routes
Pro Tip: Always check with your local council for additional licensing schemes. Many councils operate "Additional" or "Selective" licensing that may cover smaller HMOs or specific areas.

- Gross Monthly: £2,750 (5 rooms)
- Annual Gross: £33,000
