When investing in rental property in Edgware, one decision landlords might make is whether to let a property as a single let or operate it as a House in Multiple Occupation (HMO).

‘Might make’ is an operable term here; sometimes, there is a limit to the number of HMO properties in a given area, which may make the decision for you.

If not, though – if the choice, as they say, is yours – which option is best?

Both options can be profitable, but they come with different levels of involvement, regulation, and risk.

Understanding the differences will help you choose the strategy that suits your goals, finances, and appetite for management.

What Is a Single Let?

A single let is rented by one household – such as a couple, family, or even an individual – under a single tenancy agreement.

Typical characteristics:

One rent payment per month.
Lower management intensity.
Often longer tenancies and greater stability.
Simpler regulatory and safety requirements compared with HMOs.

Single lets are often favoured by landlords seeking more predictable day-to-day management.

What is an HMO?

An HMO (House in Multiple Occupation) is a property rented to three or more people forming more than one household who share facilities such as a kitchen, bathroom, or toilet.

Common examples include:

Student houses.
Professional house shares.

HMOs are more tightly regulated than standard single lets and usually require specific HMO licences from the local council, in our case Barnet Council, depending on the size of the property and local schemes.

Rental Income and Yield

HMOs often generate higher gross rental income because each room is rented separately, creating multiple income streams from one property. This structure can significantly boost yield compared with letting the same property as a single let.

Single lets usually produce lower gross income but come with fewer operating costs and less day-to-day management.

When comparing strategies, it is important to look at net yield and cash flow after costs. The asking rent of an HMO will often include utilities, TV licences and internet, and cleaners.

Management and Time Commitment

Single lets are in many ways easier to manage, with one household, fewer tenancy changes, and less wear and tear on communal areas. Communication and admin are simpler because you deal with a single tenancy and a single set of occupiers.
HMOs require more involvement: more frequent room turnovers, higher maintenance of shared spaces, and more day-to-day communication with multiple tenants.

Because of the workload and regulatory complexity, many HMO landlords choose professional management rather than self-managing.

Licensing and Legal Requirements

HMOs in Edgware, as part of the London Borough of Barnet, come with stricter regulations than standard single lets – although, with the introduction of licensing on normal single let properties, this gulf is narrowing to some extent.

Depending on the size and location of the property, this can include:

Mandatory HMO licensing for larger HMOs that meet national criteria (for example, five or more occupiers forming two or more households, sharing facilities).
Additional or selective licensing where local councils extend licensing to smaller HMOs or specific areas, meaning even three-bed house shares can need a licence.
Higher safety and amenity standards, such as fire doors, interlinked smoke/heat alarms, emergency lighting or signage where required, minimum room sizes, and defined ratios of kitchens and bathrooms to occupants.
Regular inspections and ongoing management standards, with penalties if licence conditions or HMO management regulations are breached.

Single lets do not require the same level of licensing. However, landlords must still comply with core legal obligations, such as gas and electrical safety checks, EPC requirements, deposit protection, and relevant tenancy law and local licensing schemes.

Risk and Stability

Single lets often attract longer-term tenants, such as families or settled professionals, which can mean more consistent income and fewer changeovers. However, when the property is empty, your rental income usually drops to zero until a new tenant moves in.
HMOs may experience higher turnover and require more tenant management, but rental risk is spread across multiple occupiers. If one room is empty, income from the remaining rooms can still cover a substantial share of your costs.

Neither model is automatically “safer” – HMOs are more complex but can yield better, whereas single lets are more straightforward but rely on a single household to pay the rent.

Which Strategy Is Right for You?

A single let may suit you if:

You want a lower-maintenance or lower-management investment.
You prefer longer-term tenants and a more straightforward void/re-let process.
You are new to being a landlord or have limited time for day-to-day involvement.

An HMO may suit you if:

You are comfortable with more hands-on management or plan to use a specialist managing agent.
You are aiming for higher gross and net yields and can fund the additional setup and compliance costs.
You understand (or are willing to learn) the HMO licensing and management rules in your local area.

There is no universally “better” option – the right choice depends on your goals, resources, risk tolerance and the demand in your target area.

Speaking to a knowledgeable local letting agent or HMO specialist can help you assess which route is most suitable for your property and strategy.

Frequently Asked Questions about HMO vs Single Let

What qualifies as an HMO in Edgware?
A property is generally treated as an HMO if it is occupied by three or more people who are not all from a single household and who share facilities such as a kitchen, bathroom or toilet. Detailed statutory definitions and exemptions apply, so always check the rules for your specific situation.

Do all HMOs need a licence?
Many do, but not all. Larger HMOs are subject to mandatory licensing, and many councils also extend licensing to smaller HMOs or certain streets/areas through additional or selective schemes. Always check current requirements with your local authority before you start letting.

Are HMOs more profitable than single lets?
They can be. HMOs often deliver higher gross yields and stronger cash flow, but this usually comes with higher setup costs, ongoing expenses, more frequent voids, and more management and compliance. Your actual profit will depend on local demand, your financing, costs and how well the property is run.

Can I convert a single let into an HMO?
Possibly, but you may need planning consent (for example, where Article 4 directions restrict HMO use), one or more HMO licences, and property alterations to meet space, fire and amenity standards. Always check planning policy and licensing rules before starting works.

Are HMOs riskier than single lets?
HMOs are more complex and more highly regulated, but risk is spread across multiple tenants rather than relying on a single household. Single lets are simpler and often more stable in terms of occupancy, but void periods mean a complete loss of rent while the property is empty.
