Houses in Multiple Occupation (HMO’s) present a great opportunity for landlords because properties of this type commonly offer a higher than average rental yield compared with standard buy to lets.

HMO’s can require more work to maintain, so familiarise yourself with your responsibilities and ensure you are prepared to undertake the work involved before you invest.

Why HMO property may offer higher rental yields

When you buy an HMO property, the rental income from multiple rooms (as opposed to renting the property out as a single dwelling) often results in higher income and therefore is more profitable than renting the property to a single family unit.

Below is an example of how higher rental yield can be achieved by letting a property as an HMO.

A landlord owns a three-bedroom house. The landlord could rent the property to one family unit for £700pm.

However, if the landlord rented out each of the 3 bedrooms to different people, with a monthly rent of £350 per room per month (assuming this is realistic for the property), this would mean a total of £1,050 from three individuals and an increase in overall rental income of £450 each month on the property.

It may also be possible to convert reception rooms into bedrooms (which a family may not choose to do) and therefore increase the potential rental income even further.

What qualifies as an HMO property?

An HMO is a house or flat, let to 3 or more unrelated people, that share facilities such as a bathroom or kitchen. If you require a standard buy to let mortgage click here.

What is a Multi-Unit Block?

We can also source mortgages for multi-unit blocks. These are classified as anything from a semi-detached house split into two self-contained flats or a new purpose built block of 20 self-contained flats on one freehold title.

Do I need an HMO licence?

You must have a licence if you’re renting out a large HMO. Your property is defined as a large HMO if all of the following apply:

  • It is rented to 5 or more people who form more than 1 household
  • It is at least 3 storeys high
  • Tenants share toilet, bathroom or kitchen facilities.

Even if your property is smaller and rented to fewer people, you may still need a licence depending on the area the property is located in.

If unsure, check with your local council.

Applying for an HMO licence

The UK government's website offers a postcode-based search in order to identify which council issues licences for your property, and where you can access further information regarding HMO's and their licensing:

Failure to apply for a licence when one is required can carry a fine of up to £20,000 plus costs.

It is worth noting that:

  • You will need a separate licence for each HMO you run
  • Councils may have long timeframes (months) for processing a licence, so plan ahead
  • There are conditions associated with an HMO licence, including (but not limited to):
    • The property must have adequate space and facilities for the residing tenants
    • The manager of the HMO (you or the agent) must be ‘fit and proper’ e.g. no criminal record or breaches of landlord laws or codes of practice
    • Gas certificates must be updated annually and sent to the licensing council
    • Smoke alarms must be installed and maintained
    • Safety certificates for all electrical appliances must be available on request
    • If you fail to meet the conditions on a licence without a reasonable excuse you are committing a criminal offence and could face a fine of up to £5,000.

What differentiates HMO mortgages from standard buy-to-lets?

There are a couple of differences between standard buy-to-let and HMO mortgages, most notably in availability, product rates, and lender fees.

As HMO’s have multiple occupants, they are deemed a higher risk to loan money against than a normal buy-to-let. This is because HMO tenants tend to have a more transitional and/or seasonal (e.g. students) lifestyle, which can mean higher levels of tenant turnover and voids, should one or more of the tenants move out without immediately being replaced.

A single family unit in a standard buy-to-let will tend to be more settled with longer-term plans to reside in the property. 

Secondly, due to the aforementioned risk with lending to an HMO and the specialist nature of the mortgage, the lender’s fees are often higher on HMO-specific products.
