How much more yield does an HMO produce vs a single let?

A typical HMO produces 40–70% more gross rent than the same property let as a single dwelling. For example, a 5-bed house let as a single let for £1,400/month generates £16,800/year gross rent. The same property let as an HMO at £550/room generates £33,000/year — nearly double. However, HMO running costs are also substantially higher due to landlord-paid bills, higher management fees, and greater maintenance. The net yield premium over a single let is typically 3–5 percentage points, not the full gross difference.

Q: What is a good HMO yield in the UK?

A good gross HMO yield in the UK is typically 10–14%. Net yield — after running costs including bills, management, maintenance, licensing, and insurance but before mortgage interest — typically sits at 6–9% for a well-run property. The net yield needs to be sufficient to cover mortgage interest and still leave positive cash flow. With HMO BTL mortgage rates at 5–6% in 2025, a net yield of at least 7–8% is generally required to achieve meaningful positive monthly cash flow on a 75% LTV mortgage.

Q: How do I calculate HMO yield?

Gross HMO yield = (Number of rooms × Monthly rent per room × 12) ÷ Purchase price × 100. Net yield = (Annual rent adjusted for voids − All running costs excluding mortgage interest) ÷ Purchase price × 100. Running costs for an HMO typically include landlord-paid utility bills (£400–£700/month for a 5-bed), management fees (12–15% of rent), maintenance (1.5–2% of property value/year), HMO licensing (amortised), and insurance. The net yield is always significantly lower than the gross yield — typically by 4–6 percentage points for a fully managed HMO.

UK HMO yield benchmarks — 2025

The table below shows what gross and net yields to expect from well-located HMOs in major UK cities, based on current market rents and typical purchase prices in each market.

City / area	Typical gross yield	Typical net yield	Avg room rent	Verdict
Glasgow (G51, G31)	12–15%	7–10%	£500–£600	Strongest UK market
Nottingham (NG7)	12–14%	7–9%	£480–£580	Excellent — best English city
Sheffield (S10, S3)	10–13%	6–8.5%	£530–£650	Very strong, good demand
Liverpool (L6, L7)	10–13%	6–8%	£500–£600	Good, improving
Leeds (LS6)	9–12%	5.5–7.5%	£560–£680	Good, higher entry prices
Birmingham (B15, B29)	8–11%	5–7%	£550–£700	Marginal — rising prices
Manchester (M14)	7–10%	4–6%	£600–£750	Marginal for mortgaged investors
London (outer zones)	5–8%	2–5%	£800–£1,200	Cash flow rarely positive

Net yield figures assume full management, landlord-paid bills, and average maintenance. Self-managed HMOs with lower costs can achieve 1–2pp higher net yields. Source: market data and operator benchmarks, mid-2025.

Why gross yield and net yield differ so much for HMOs

The gap between gross and net yield is larger for HMOs than for any other UK property investment type. A well-run 5-bed HMO at 12% gross typically nets 6–8% after costs — a gap of 4–6 percentage points. For single-let properties the gap is typically 1.5–2.5pp. There are three reasons the HMO gap is so much wider:

Landlord-paid bills. HMO tenants pay room rent inclusive of bills. The landlord pays all utility costs — gas, electricity, water, council tax, and broadband. On a 5-bed property in 2025, this typically runs £450–£650/month, directly reducing net yield.
Higher management fees. HMO management requires more active involvement than single-let management — regular inspections, more frequent tenant turnover, licensing compliance checks. Specialist HMO agents typically charge 12–15% of rent, versus 8–10% for single-let management.
Higher maintenance. With more tenants sharing fewer communal spaces, wear and tear on kitchens, bathrooms, hallways, and shared equipment is significantly higher. Budget 1.5–2% of property value per year rather than the 1–1.5% that applies to single-let properties.

What is a good HMO yield in the UK?

A good gross HMO yield is 10–14%. Net yield after running costs (bills, management, maintenance, licensing, insurance) typically sits at 6–9% for a well-run property. With HMO BTL mortgage rates at 5–6% in 2025, you need a net yield of at least 7–8% to achieve meaningful positive monthly cash flow on a 75% LTV mortgage. Use the calculator above to see what the numbers look like for any specific deal.

How much more yield does an HMO produce than a single let?

A typical HMO produces 40–70% more gross rent than the same property let as a single dwelling. However, HMO running costs are also substantially higher — particularly landlord-paid bills and management. The net yield premium over a single let is typically 3–5 percentage points, not the full gross difference. The calculator's side-by-side comparison shows both figures for the same property.

How do I calculate HMO yield?

Gross HMO yield = (Rooms × Monthly rent × 12) ÷ Purchase price × 100

Net HMO yield = (Annual rent adjusted for voids − All running costs excl. mortgage) ÷ Purchase price × 100

Running costs for a 5-bed HMO typically include: bills (£5,500–£7,800/year), management (12–15% of rent), maintenance (£3,500–£5,500/year), licensing (£200–£300/year amortised), and insurance (£750–£1,400/year).

Does occupancy rate matter as much for HMOs as single lets?

Yes — and in a different way. An HMO with 5 rooms doesn't go void all at once. When one tenant leaves, the other four rooms continue generating income. This makes HMO income more resilient to voids than a single let (where the entire rent stops when the tenant leaves). However, high turnover in student HMOs means void costs are still significant — budget for at least 1–1.5 months void per room per year in your occupancy rate assumption, giving 88–94% effective occupancy on a well-managed property.
