UK Shared Equity vs Shared Ownership Compared

Shared equity and shared ownership are different routes to lower-deposit home ownership. The terms are often used interchangeably but the legal and financial structures differ. Understanding which structure applies affects the deposit, the monthly cost, and what happens at sale.

Shared equity

Shared equity provides a loan that funds part of the purchase price. The buyer owns 100% of the property and takes out a conventional mortgage for the rest. The equity loan typically does not require monthly payments for a period (interest may apply after a defined period), and the loan is repaid as a percentage of the property's value at the time of repayment.

Shared ownership

Shared ownership splits the legal interest in the property. The buyer purchases a share (commonly 25% to 75%) and pays rent to a housing association or local authority on the remaining share. The mortgage covers only the owned share. The property is typically leasehold and service charges apply.

Costs compared

Shared equity typically has a smaller upfront cost than buying outright but no rent component. Shared ownership has a smaller mortgage but adds rent and service charge to the monthly cost. Combined monthly costs vary; comparing total monthly outflow (mortgage plus rent plus service charge plus insurance) gives the fairest comparison.

Selling and staircasing

Selling a shared equity property requires repaying the equity loan at the current market percentage. Shared ownership sale typically gives the housing association first refusal and may be constrained by the lease terms. Staircasing (increasing the owned share) is specific to shared ownership; the equivalent in shared equity is repaying part or all of the equity loan.

Shared equity in detail

Shared equity provides a loan that funds part of the purchase price, typically 5% to 40% of the property value. The buyer owns 100% of the property and takes out a conventional mortgage for the rest. The equity loan typically does not require monthly payments for a defined period (5 years in the Help to Buy structure), after which interest begins (1.75% in year 6, rising annually with RPI + 2%).

The equity loan is repaid as a percentage of the property's value at the time of repayment, not the original cash amount. If the original loan was 20% and the property has doubled in value, the repayment is 20% of the new value, which is double the original cash amount. The borrower retains the proportional gain on their 80% share but the government shares in the property appreciation through the equity loan.

Repayment of the equity loan can be made in two ways: full repayment at any time during the term, or repayment of part of the loan in 10% staircasing chunks. Most borrowers repay the full equity loan when they sell the property, refinance to a larger conventional mortgage, or reach the end of the standard mortgage term.

The Help to Buy Equity Loan (England) closed to new applicants in March 2023. Borrowers with existing equity loans continue under the original terms. Wales operates Help to Buy Wales (continuing), with different terms. Scotland operates the Open Market Shared Equity (OMSE) scheme through local authorities. The First Homes scheme (England) operates differently, providing a discount on the open-market price rather than an equity loan.

Shared ownership in detail

Shared ownership splits the legal interest in the property. The buyer purchases a share (commonly 25% to 75%, with the minimum reduced to 10% for new schemes since 2021) and pays rent to a housing association or local authority on the remaining share. The mortgage covers only the owned share. The property is typically leasehold and service charges apply on the full property.

The rent on the unsold share is typically calculated as 2.75% of the unsold share value, payable monthly. Rent rises annually under a formula in the lease (commonly RPI or CPI + 1% for newer leases). Over 10 to 20 years, compounded rent rises can be substantial; the total rent paid often approaches or exceeds the cost of the unowned share at original purchase price.

Staircasing allows the buyer to increase their owned share over time. The new standard lease (from April 2021) allows 1% annual staircasing increments at lower cost than the traditional 10% increments. Each staircasing transaction requires a fresh valuation, legal work, and stamp duty (where applicable). Cost of additional shares is based on current market value at the time of staircasing, not the original purchase price.

Service charges cover building maintenance, insurance, communal areas, and major works. The leaseholder pays the full service charge regardless of the owned share. This can be a substantial annual cost (often GBP 1,000 to GBP 3,000+ depending on the development) that surprises buyers who assume costs are proportional to share owned.

Costs and monthly outgoings compared

Shared equity typically has a smaller upfront cost than buying outright but no rent component. The monthly outgoings are mortgage payment plus standard property costs (council tax, insurance, maintenance). The equity loan does not require monthly payment for the initial period.

Shared ownership has a smaller mortgage (only on the owned share) but adds rent and service charge to the monthly cost. Combined monthly costs typically exceed equivalent conventional mortgage in the early years (because the rent component is substantial) but can reduce over time as the borrower staircases to a larger owned share.

A worked example: a GBP 300,000 property bought 50/50 under shared ownership requires a GBP 150,000 mortgage (perhaps GBP 750 to GBP 900 per month) plus rent of around GBP 344 per month (2.75% of GBP 150,000 unsold share / 12) plus service charge of perhaps GBP 200 per month. Total monthly cost around GBP 1,294 to GBP 1,444. Buying the same property outright with a 10% deposit requires a GBP 270,000 mortgage at perhaps GBP 1,400 to GBP 1,600 per month plus no rent or service charge (for freehold). Monthly costs are similar but the structures and equity ownership differ materially.

Comparing total monthly outflow (mortgage plus rent plus service charge plus insurance) gives the fairest cost comparison between schemes. The choice often depends on the deposit available (shared ownership requires less) and the household's appetite for the leasehold structure (shared ownership is typically leasehold; equity loan can be freehold).

Selling and resale considerations

Selling a shared equity property requires repaying the equity loan at the current market percentage. The buyer of the property takes a standard conventional mortgage; the equity loan does not transfer. The seller's net proceeds are the sale price minus the equity loan repayment minus the conventional mortgage outstanding.

Shared ownership sale typically gives the housing association first refusal (a pre-emption period, often 8 weeks). The housing association may find a buyer from their waiting list; if not, the open-market sale proceeds (subject to the lease terms). The pre-emption period can extend the time to sale.

The buyer pool for shared ownership resale is constrained to those meeting the scheme's eligibility criteria (income caps, first-time buyer status in some cases). This can make resale slower than equivalent open-market properties. In falling markets, the constrained buyer pool can amplify price falls.

Staircasing to 100% before sale (where affordable) removes the constrained buyer pool and allows standard open-market resale. The cost of staircasing in a rising market needs to be weighed against the potential benefit of unconstrained resale.

Which suits which buyer

Shared equity tends to suit first-time buyers with sufficient income to support a near-full mortgage but insufficient deposit to access a competitive standard mortgage. The equity loan boosts the deposit, accessing lower-LTV mortgage rates. The trade-off is sharing future appreciation with the government through the equity loan.

Shared ownership tends to suit first-time buyers with modest deposit and income who could not afford a full mortgage on the property. The smaller share means smaller mortgage, lower deposit, and lower mortgage payment. The trade-off is the rent on the unsold share, the leasehold structure, and the staircasing complexity.

First Homes (England) suits first-time buyers in areas where qualifying properties are available. The 30% discount is locked into the property (preserved on resale) and applies on the purchase price. The buyer gets a smaller mortgage on a discounted property; the discount cannot be 'banked' as equity gain because resale price is also discounted.

For buyers with stronger financial positions, standard open-market purchase is typically preferable because none of the schemes' constraints apply. The deposit requirement and ongoing affordability determine whether open-market is accessible. Brokers can advise on which route fits a specific borrower's profile.

Comparing total monthly cost across structures

A worked comparison clarifies the trade-offs. Consider a GBP 300,000 new-build property: option A is shared equity with the buyer taking 60% (GBP 180,000 mortgage at 5%, GBP 120,000 equity loan); option B is shared ownership at 50/50 (GBP 150,000 mortgage at 5%, rent on the GBP 150,000 unsold share); option C is conventional purchase at 90% LTV (GBP 270,000 mortgage at 5%, GBP 30,000 deposit).

Option A monthly costs: GBP 180,000 mortgage at 5% over 25 years = approximately GBP 1,053 per month. Equity loan typically has no monthly payments for the first 5 years; interest starts in year 6 at 1.75% rising annually. Total monthly housing cost in early years: around GBP 1,053.

Option B monthly costs: GBP 150,000 mortgage at 5% over 25 years = approximately GBP 877 per month. Rent on the GBP 150,000 unsold share at 2.75% = GBP 4,125 per year or GBP 344 per month. Service charge on the leasehold property typically GBP 100 to GBP 300 per month; assume GBP 200. Total monthly housing cost: GBP 877 + GBP 344 + GBP 200 = GBP 1,421.

Option C monthly costs: GBP 270,000 mortgage at 5% over 25 years = approximately GBP 1,579 per month. No rent or shared ownership charges; for leasehold properties (such as new-build flats), service charge applies. Total monthly housing cost: GBP 1,579 plus any service charge.

The comparison shows that shared equity (option A) has the lowest monthly cost in the early years; shared ownership (option B) has middle cost with the rent and service charge components; conventional purchase (option C) has the highest mortgage payment but no rent.

Long-term implications differ. Shared equity requires equity loan repayment at the current property value percentage; if the property appreciates, the repayment cash amount grows. Shared ownership requires staircasing to reach full ownership; staircasing at current market value can be expensive in rising markets. Conventional purchase requires no further action beyond the standard mortgage.

Practical resale considerations for both structures

Selling a shared equity property requires repaying the equity loan at the current market percentage. If the property has appreciated, the equity loan repayment is larger in cash terms than the original loan; the borrower retains the proportional gain on their owned share.

Selling shared ownership typically gives the housing association first refusal (a pre-emption period, often 8 weeks). The housing association may find a buyer from their waiting list. If no buyer is found within the pre-emption period, open-market sale (subject to lease terms) proceeds.

Both structures can take longer to sell than equivalent open-market properties because of the specific buyer pool and additional process requirements. For sellers planning move timing, allowing for the additional sale complexity is sensible.

Frequently asked questions

Which is cheaper monthly?

It depends on the specific deal, property value, and the share owned. Shared ownership tends to have a smaller mortgage but adds rent and service charge; shared equity tends to have a larger mortgage but no rent. Total monthly cost can be similar; the structures differ in long-term outcome. Staircasing in shared ownership and equity loan repayment in shared equity both involve future cash outflows that need to be planned for.

Can either be used with a Lifetime ISA?

Yes, subject to the Lifetime ISA price cap (GBP 450,000 across the UK) and the scheme rules. The 25% LISA bonus can contribute to the deposit. For dedicated first-home saving, the LISA is valuable regardless of whether shared equity or shared ownership is ultimately used. Coordination requires the conveyancing solicitor to know about the LISA because the funds typically need to be released by the LISA provider directly to the conveyancer.

What happens if the property price falls?

In shared equity, the equity loan repayment percentage stays the same but the cash amount falls with the value. The borrower carries the loss on their owned share. In shared ownership, the unsold share value also falls; staircasing then costs less. Both structures can leave the borrower in negative equity (mortgage exceeds owned share value), constraining ability to remortgage or sell.

Are both schemes available across the UK?

Shared ownership is widely available across the UK with regional variations. Shared equity schemes vary by nation: England's Help to Buy Equity Loan closed in 2023; Wales' Help to Buy Wales continues; Scotland's OMSE operates through local authorities; Northern Ireland's Co-Ownership Housing is similar to shared ownership. Check the current scheme available in the specific area.

Is the rent on shared ownership reviewed annually?

Typically yes, under a formula set out in the lease. The base is usually a percentage of the unsold share value (commonly 2.75%). Older leases often use RPI for annual rent reviews; newer leases (from April 2021) commonly use CPI + 1% as the upgrade formula. The lease specifies the exact mechanism and any cap on annual increases.

Can shared equity and shared ownership be combined?

Not directly. They are alternative schemes and typically cannot be combined on a single property. A buyer chooses one route at purchase. Some schemes have been called 'shared equity' loosely but use a shared ownership structure; reading the specific scheme documentation confirms which structure applies.

How does inheritance affect shared ownership and shared equity properties?

Both can be inherited as part of the estate. Shared ownership leases pass under the will and the inheritor takes over the lease (typically subject to the housing association's right to require the share to be sold within a defined period). Shared equity loans remain attached to the property; the inheritor takes over the property subject to the equity loan obligation. Specialist legal advice on inheritance of these property types is often valuable.
