Multifamily housing is a type of housing where more than one housing unit is contained within the same building. Houses in Multiple Occupations (HMOs) are similar, in that multiple, separate tenants live in the same building and share at least a toilet, bathroom, or kitchen. The most common form of multifamily housing is the apartment block, which can hold anywhere from two or three to several hundred apartments. Prices for flats and apartments tend to be lower than houses and they can represent a good investment to landlords and property owners.

3. There Was a 43% Increase in Investment in Multifamily Housing in the First Half Of 2022.


Multifamily housing is a type of housing where multiple housing units or premises are contained within the same building. The units can be stacked vertically or lined up horizontally. Common examples include blocks of flats and apartment buildings. With house prices rising so sharply, more people are turning to multifamily housing as an affordable means of renting, which also means that investment has increased.

The first half of 2022 saw a record H1, with a 43% increase in investment in this kind of housing, although this does come against the first half of 2021 which included some lockdowns and remaining Covid restrictions.

More multifamily housing is being built. 150,000 units are considered to be in the planning stage, under construction, or have been completed. This does not include those properties that have been completed and already have tenants but is an indication of more multifamily housing investment.

London is the most popular area for multifamily housing units.

6. The Number of Houses of Multiple Occupancy in the UK Dropped By 3% In 2021.


Houses of Multiple Occupancy (HMO) can be considered another form of multifamily unit. For a development to be considered an HMO it must have three or more separate tenants, making up at least two households, and the tenants must share at least a bathroom, kitchen, or toilet.

In some cases, HMO tenants can share all of these rooms and just have separate living and sleeping areas. New restrictions and regulations were placed on HMOs in 2018, and analysts believe that these, which aim to increase living space and living conditions for tenants, have led to a drop in the number of HMO units. In 2021, there was a 3% drop in HMO unit numbers.

7. There Are Now Just Over 55,000 Houses in Multiple Occupancy Across England.

(Buy Association)

Following the decline in numbers in 2021, there are believed to be approximately 55,000 HMO units now across England. This doesn’t take into account figures for Scotland, Wales, or Northern Ireland.

8. Total HMO Stock Is Worth Approximately £11.2 Billion.

(Buy Association)

Although the number of HMOs has dropped, the stock of this type of housing still holds a lot of value. Considering all HMO units in England, this segment of the housing market is believed to be worth £11.2 billion, which equates to more than £200,000 per individual unit.

9. 21% Of Dwellings in the UK Are Flats.

(Statista 2)

Multifamily housing is considered a good investment opportunity for landlords and investment groups. Having multiple tenants means minimizing exposure to tenancy voids. A total of 4.4 million people rent property in the UK, meaning that multifamily housing owners have a lot of potential tenants to target.

11. 60% Of Private Rented Properties in the UK Are Houses.

(Knight Frank)

The housing market can be broken down into owner-occupied buildings, social housing, and privately rented housing. To become a social housing landlord, it is necessary to register. Private landlords also need to register, but the process is simpler, and there are considered to be more investment opportunities in the private rental market. Although 60% of the private rental market is made up of houses, this leaves 40% of property stock that includes flats and apartments.

A one-bedroom flat has an average rental value of £758 per month in London and £614 per month outside the capital.

13. A Quarter of UK Residents Have to Spend More Than 40% Of Their Disposable Income on Rent.
