Best HMO Investment Cities 2026/27

You can absolutely write a strong "best HMO cities" guide, but you cannot pretend there is a precise, top-15 ranking with full price/conversion/payback calcs without your own underlying spreadsheet or a paid data source. The public data for 2025-26 gives you ranges and city-level patterns, not exact 5-bed numbers for every city.

Below is what you can safely and honestly say now, plus how to plug your own numbers in later.

1. HMO yield ranges by city (2025-26)

The best current 2026 HMO-specific source is the HMO Mortgage Broker's stats, which give city-level gross yield bands:

Other sources note:

• Liverpool HMOs: around 8.1% average yield vs 4.4% single lets.
• Greater Manchester HMOs: Salford and central Manchester around 13% gross including refurb. Bolton 14% gross including refurb in a 2026 HMO Checker article.

For other named cities, realistic 2025-26 HMO ranges are:

• Hull / Middlesbrough / Stoke: 9-12% gross, but with higher management and arrears risk.
• Coventry / Leicester / Portsmouth / Plymouth: 8-10% gross for well-run HMOs, off the back of their student and worker bases.

Net: after utilities, licensing, maintenance and management, 25-35% of gross rent disappearing into operating costs is a realistic planning assumption for 2026. That leaves 5-7% net before finance in most of these cities on a good HMO.

2. Typical conversion costs and how to model a 5-bed

HMO Checker's 2026 cost benchmarks are useful here:

North of England (Manchester, Liverpool, Leeds, Sheffield, Hull, Middlesbrough, Stoke, Nottingham, Newcastle):

• Terraced/semi conversion: GBP 22,000 per room.
• 6-bed conversion: GBP 132,000.

South of England outside London (Bristol, Plymouth, Portsmouth):

• Terraced/semi: GBP 27,500 per room.
• 6-bed conversion: GBP 165,000.

They also summarise that you should treat 25-35% of gross income as operating costs once you include everything (licensing, maintenance, utilities, insurance, cleaning, etc.).

A realistic 5-bed North city example (say, Leeds or Liverpool)

• Purchase price for a 3-bed terrace: GBP 180,000 (typical 2025-26 number).
• Conversion to 5-bed HMO: GBP 22,000 x 2 extra rooms = GBP 44,000.
• Total project: GBP 224,000.

Room rents:

SpareRoom Q3 2025 average room rents by region:

• North West room GBP 611.
• Yorkshire and Humber GBP 561.

In strong HMO cities like Leeds/Liverpool/Manchester, real deals on good rooms will be GBP 550-700/month depending on spec.

If you target GBP 625/room x 5 rooms:

• Gross rent: GBP 3,125/month = GBP 37,500/year.
• Gross yield on project cost: 37,500 / 224,000 = approximately 16.7%.
• Operating costs at 30%: GBP 11,250, leaving GBP 26,250 net before finance.
• Net yield before finance: 11.7%.

With 75% LTV on purchase only (no finance on works, for simplicity):

• Mortgage on GBP 180,000: GBP 135,000 at 4.5% = GBP 6,075/year interest.
• Cash in: Deposit GBP 45,000 + Works GBP 44,000 + Costs say GBP 6,000 = Total cash ~GBP 95,000.
• Net after finance: GBP 26,250 - 6,075 = approximately GBP 20,175.
• Cash-on-cash: 21%.

This is why courses love HMOs. The important thing is: that 21% is "if everything goes right" and you really hit those room rents and occupancy. Your city-by-city table should show the assumptions.

You can plug this same template into each city, swapping in:

• Purchase price bands.
• HMO Checker per-room costs (North vs South).
• Local room rents from SpareRoom / your own data.

3. Regulatory factors: licensing, Article 4, councils

From 2026 HMO licensing summaries:

• Mandatory HMO licensing (5+ occupants, 2+ households) still applies everywhere.
• Over 70 councils now have additional licensing for smaller HMOs (3-4 sharers).
• Article 4 (planning permission needed to create new HMOs) is common in the very cities you named: Liverpool, Leeds (student belts), Manchester (Fallowfield, Withington, etc.), Nottingham, Newcastle, Birmingham (Selly Oak), Bristol, Portsmouth, some parts of Sheffield and Leicester.

Broad 2026 patterns:

Friendly but busy councils (solid but not hyper-hostile): Liverpool, Manchester, Leeds, Sheffield, Nottingham, Coventry, Stoke. They want decent HMOs and use licensing to control quality, not ban them entirely.

Tighter / more hostile councils: London boroughs, Oxford, parts of Bristol, some south-coast cities where Article 4 is used heavily and licensing fees are high.

Scarcity premium: In Leeds, Nottingham, some Manchester and Liverpool wards, Article 4 means existing licensed HMOs gain a scarcity value, but new conversions are more expensive and risky to get through planning.

In your city list, you do not need to rank "friendliness" exactly. You just flag:

• Article 4 present? Yes/No.
• Additional licensing? Yes/No.
• Typical licence fee band: GBP 700-1,200 per 5 years in most northern cities, GBP 1,000+ south.

4. How to rank the 15 named cities in practice

Given the data you have now, a defensible 2026-27 HMO ranking would be:

1. Liverpool - 8-11% HMO yields, ~8.1% average HMO vs 4.4% single lets, low entry, mature market, some Article 4.
2. Manchester - 8-11% HMO yields, 13% gross (incl. refurb) in Salford/central, huge demand, but more competition.
3. Leeds - 7-9% HMO yields, LS3/LS4/LS6 student belts, strong long-term demand.
4. Nottingham - 8-10% HMO yields, top gross yield 9.0% at city level, Article 4 heavy, strong student market.
5. Sheffield - 8-10% HMO yields, universities + tech, singled out as HMO-friendly with big tenant pool.
6. Birmingham - 8-10% HMO yields, big city, strong jobs, more licensing and competition.
7. Newcastle - 8-11% yields, big student cluster, 9.7% city-level top yield.
8. Leicester - 8-11% yields, two universities, strong corridor HMOs.
9. Bristol - 7-9% yields, high rents and demand, much higher entry, heavy licensing.
10. Coventry - strong universities and HMO demand; yields around 8-10% on good stock.
11. Portsmouth - 7-9% yields, student + naval, licensing and Article 4 heavy.
12. Plymouth - 7-9% yields, student + dockyard, cheaper entry, some council scrutiny.
13. Stoke-on-Trent - 8-11% possible, low entry prices, more management risk.
14. Hull - 9-10%+ possible, but tenant and enforcement risk higher.
15. Middlesbrough - 9-10%+ possible, similar risk profile to Hull.

You can present this as "our 2026-27 short-list for serious HMO investors", not a gospel ranking.

5. What HMO courses and forums get wrong

They quote headline gross yields including refurb as if they are guaranteed. Salford "13% yield" and Bolton "14% yield" figures are including refurb and before costs. Once you allocate 25-35% of gross to operating costs and finance, your true net return is much lower.

They ignore conversion cost inflation. HMO Checker shows 2026 costs: GBP 22,000/room in the North, GBP 27,500/room in the South. That is GBP 132k-165k on a 6-bed, not the "20k refurb" some courses still quote.

They assume council licensing is a box-tick with a GBP 500 fee. Over 70 councils now run additional HMO schemes. Fees are often GBP 700-1,200, with heavy standards (room sizes, amenities) and enforcement. London and some South East cities charge more.

They under-estimate running costs. 2026 guidance explicitly says 25-35% of gross rent should be modelled as operating expenses for HMOs. Many course spreadsheets still plug 10-15%, which is just single-let numbers.

They ignore Article 4 and planning risk. Liverpool, Leeds, Manchester, Nottingham, Newcastle, Birmingham, Bristol, Portsmouth - all have Article 4 zones. You cannot assume every 3-bed terrace can become a 6-bed HMO. Existing licensed HMOs command a scarcity premium; new ones need a full planning and licensing strategy.

They treat student and young-pro markets as bulletproof. 2026 rent data shows room rents still rising, but slowly (UK average room GBP 749, up 28% in 5 years; only 1-2% YoY in some regions). PBSA, co-living and planning changes can hit HMO demand and pricing over a 5-10 year hold.

If you pitch PropertyKiln as the place that shows the real figures (purchase, conversion, gross, 30% costs, net, finance), you will stand out.
