Shared ownership – an impactful solution to the UK’s affordable housing shortage

Gresham House’s managing director of housing, Ben Fry, examines the role of shared ownership in tackling the UK’s lack of affordable homes.

The UK has a well-documented shortage of affordable housing. A structural shortfall in housing supply, combined with long-term demand growth, has meant that for several decades, property prices have grown faster than average incomes.


Today, the average UK home costs nine times average earnings1. When compared to the maximum mortgage availability needed to buy a home, of around only 5x earnings2,  the result is that in more than 93%3 of local authorities across the country, the average earner cannot afford to buy the average home.


To compound the situation, housing associations that have delivered a significant volume of affordable housing over recent decades have seen their development capacity reduce materially, due to the requirement to reinvest in their existing housing stock, allocating c.£35bn to improve fire safety and energy efficiency by 2030.5


This backdrop creates an urgent need for patient investment capital at scale to help deliver affordable homes to the UK. Shared ownership offers a great way to provide these much-needed homes, delivering a tangible social impact while generating a secure, inflation-linked income for investors. What is more, geographically focused investment in shared ownership can help local authorities meet demand for affordable housing in their locality.

What is shared ownership?

Shared ownership is a government-backed part-buy/part-rent solution that offers people on lower and middle incomes, such as young families and key workers, an affordable route onto the property ladder by reducing deposit and income requirements.

How does it work? 

A purchaser acquires an initial (typically 25%) equity share in a house. They then pay government subsidised (i.e. below-market) rent on the remaining share of their home, to a registered provider of social housing, reducing their monthly income requirements. The shared owner has the option to incrementally purchase additional shares in their home at the prevailing open market value, known as “staircasing”.

How does shared ownership improve affordability for residents?6

The part buy/part rent model improves the initial affordability of home ownership in two ways:

  • Reduced deposit, through buying a smaller share in the property.
  • Reduced household income requirements, through subsidised rents at 30% discount to market.

The reduced deposit and income requirements under shared ownership provide an affordable route onto the housing ladder for 7.5 million people7 who would otherwise be unable to own their home.

Increases homeownership eligiblity7

Shared ownership also provides owners with significant longer-term savings. Subsidised rents at a discount to market of c.30% mean a shared owner can expect to save more than £300k over a lifetime compared to remaining in the private rented sector.8


In addition to the lifetime saving, shared owners can expect to build a financial asset of more than £400k as they own an equity stake in their property.8

Shared ownership reduces the financial barrier to homeownership

From an investment point of view, shared ownership lets investors play a part in fulfilling a key societal need by making home ownership more affordable and accessible to people on lower and middle incomes such as young families and key workers who are fundamental to the future of their community.

Investment case 

Shared ownership has the potential to deliver long-term secure, inflation-linked income from ultra long-term leases with individual residents, each of whom are part owners of their homes and thus long-term partners rather than just tenants. Investors in shared ownership benefit from the security of investing at a c.30% discount to open market value, offering protection that improves over time.


With this enhanced security, shared ownership is able to deliver a return that compares favourably with comparable residential housing strategies but with a more attractive risk profile.


In addition to financial returns, investment in shared ownership creates quantifiable social and environmental impact by delivering additional, energy efficient homes that are affordable to people on lower and middle incomes.

Local investment opportunity

As part of our shared ownership investment proposition, Gresham House offers investors the opportunity to establish and deploy locally alongside a commitment to the main UK-wide Fund9. Gresham House has experience of establishing local investment vehicles for LGPS investors dating back to 2019.

Conclusion

We believe shared ownership represents a standout solution to the structural issues affecting the UK’s regional housing markets and should be viewed as a core element in the portfolios of institutional investors looking to combine quantifiable social impact with strong and secure, inflation-linked investment returns.
