HMO vs Single Let: Which Makes More Sense?

When you're investing in a London property, one of the biggest decisions is: do you rent it out as a whole flat (single let), or convert it into an HMO (House in Multiple Occupation) and rent room by room? Both have pros and cons.

What Is an HMO?

An HMO is a property rented out to three or more people who are not from the same household — e.g. professionals sharing a house. Each tenant rents their own bedroom, and they share the kitchen, bathroom and living areas.

Single Let: Simpler, Lower Risk

Renting the whole property to one tenant (or one family) is straightforward. One contract, one rent payment, one set of relationships. Void periods are a bigger risk — if your tenant leaves, you lose all your income until you find a new one. But management is simpler and compliance requirements are lighter.

HMO: Higher Yield, More Work

Renting room by room typically delivers 20-40% higher gross yield than a single let. Instead of one tenant paying £2,500 pcm, you might have 4 tenants each paying £700 = £2,800 pcm. But there's a catch: HMOs have strict licensing requirements, more safety regulations, and much more management work.

Which Is Right for You?

Choose single let if: you want a hands-off investment, you own a flat (not a house), or you're a new landlord. Choose HMO if: you own a multi-bedroom house in a high-demand area, you're prepared for the extra compliance work, and you want maximum yield.

Conclusion

There's no one-size-fits-all answer. The right choice depends on your property, your budget, and how much time you want to spend on management. Talk to Winsor — we can help you calculate which option makes more sense for your specific property.
