Shared Ownership Scheme in 2021:  Shared Ownership reduced the amount a buyer needed to purchase at the outset. However, a smaller mortgage did not automatically mean lower total housing costs.

For mortgage advisers, the important calculation included more than the deposit. It combined the mortgage payment, rent, service charge and obligations contained within the lease.

That distinction shaped whether a Shared Ownership purchase remained affordable after completion.

At a Glance

• Buyers purchased a share of a leasehold home and paid rent on the remaining share.
• The deposit was normally calculated against the share being purchased.
• Mortgage affordability still had to include rent and other property charges.
• The new 2021 model introduced different terms for qualifying properties.
• Older Shared Ownership leases could operate under different rules.
• Advisers needed to examine both lender criteria and the individual lease.

What Was the Shared Ownership Scheme?

The Shared Ownership Scheme allowed an eligible buyer to purchase part of a property while renting the remaining share from a housing provider.

The buyer normally used a residential mortgage for the share being purchased. They then made separate rent payments to the provider.

For example, someone buying a 25% share of a £240,000 property would purchase equity worth £60,000. Their mortgage and deposit would usually relate to that £60,000 share.

However, their monthly commitment would also include rent on the remaining 75%.

Shared Ownership properties were leasehold homes. Therefore, the lease remained central to the mortgage, legal and affordability assessment.

Advisers supporting residential cases could refer to the wider Residential Mortgage Guide for related purchase considerations.

What Changed Under the 2021 Shared Ownership Model?

During 2021, the Government began introducing a revised Shared Ownership model for qualifying homes.

The reforms included the potential to:

• Purchase an initial share from 10%.
• Buy additional shares in increments of 5% or more.
• Purchase a further 1% each year for up to 15 years.
• Receive limited repair support during an initial ten-year period.
• Use leases with longer minimum terms for qualifying new homes.

These conditions did not automatically apply to every Shared Ownership property.

Homes provided under earlier programmes could retain older lease terms. Consequently, an adviser could not rely on the scheme name alone. The property’s key information documents and lease had to confirm which model applied.

How Was Shared Ownership Affordability Assessed?

A Shared Ownership mortgage application required two connected assessments.

First, the housing provider assessed whether the applicant met its eligibility and affordability rules.

Second, the mortgage lender assessed whether the borrower could maintain the loan alongside their other commitments.

The calculation could include:

• Monthly mortgage payments.
• Rent on the unowned share.
• Service charges.
• Ground rent where applicable.
• Buildings insurance arrangements.
• Existing credit commitments.
• Childcare and household expenditure.
• Expected changes to rent or service charges.

A reduced mortgage balance could help the initial calculation. However, rent and service charges could materially change the final monthly cost.

The Mortgage Costs Guide provides further information about expenses that may arise during a property purchase.

Why Did the Lease Matter?

The lease established the legal relationship between the buyer and housing provider.

It could determine:

• How rent was reviewed.
• Which service charges were payable.
• Who was responsible for repairs.
• Whether alterations required consent.
• How further shares could be purchased.
• Whether ownership could reach 100%.
• What happened when the property was sold.
• Whether subletting was permitted.

Two properties described as Shared Ownership could therefore carry different obligations.

A lender might also require the lease to contain particular mortgage protection provisions. The conveyancer was responsible for reviewing the legal terms, while the adviser assessed whether the proposed mortgage met the lender’s criteria.

What Was Staircasing?

Staircasing allowed the buyer to purchase additional shares in the property.

The cost of a new share normally depended on the property’s value when that share was purchased. If the property value increased, the price of the additional share could also rise.

Standard staircasing could involve:

• A property valuation.
• Legal fees.
• Mortgage arrangement costs.
• Housing provider administration.
• Possible tax considerations.

The revised 2021 model introduced smaller staircasing options for qualifying leases. However, advisers still needed to check the actual lease rather than assuming those terms were available.

What Should Mortgage Advisers Have Checked?

Before recommending a Shared Ownership mortgage, an adviser needed to establish:

1. Which Shared Ownership model applied

   The adviser needed the property information and lease details.

2. The share being purchased

   The lender could set minimum or maximum share requirements.

3. The complete monthly commitment

   Mortgage payments could not be assessed separately from rent and service charges.

4. The buyer’s available deposit

   The deposit was normally based on the share being purchased, but lender rules varied.

5. The provider’s affordability assessment

   Housing-provider approval did not guarantee mortgage approval.

6. Future ownership plans

   The buyer’s intention to staircase, move or sell could affect product suitability.

7. The property and lease acceptability

   The lender still needed to accept the property, valuation and lease conditions.

The mortgage application process explains how underwriting, valuation and legal work can affect a residential case.

How Could a Mortgage Adviser Help?

Shared Ownership sat between mortgage lending, affordable housing rules and leasehold ownership.

An adviser could help the applicant understand:

• Which lenders considered Shared Ownership.
• How each lender treated rent and service charges.
• The evidence required for income and deposit.
• Whether the selected share met lender criteria.
• How the initial mortgage might affect later staircasing.
• Which questions should be referred to the solicitor or housing provider.

Why Shared Ownership Knowledge Mattered to a Mortgage Network

A specialist product was not defined only by its interest rate.

Shared Ownership required the adviser to connect lender policy, housing-provider rules, property documentation and long-term affordability.

Connect Network supports advisers across residential and specialist mortgage cases. Its adviser services can help AR firms understand available placement and support routes.

Good advice begins by calculating what the buyer must sustain, not simply what they can initially purchase.

Shared Ownership Scheme FAQs

Was Shared Ownership only for first-time buyers?

No. It could also be available to some previous homeowners who could not afford a suitable property on the open market and met the applicable eligibility rules.

Was the deposit based on the full property value?

It was normally calculated against the share being purchased. Individual lender criteria still applied.

Did every 2021 property allow a 10% initial share?

No. The revised model applied to qualifying properties. Older Shared Ownership homes could remain subject to earlier lease terms.

Could a buyer eventually own the whole property?

Many leases allowed staircasing to 100%. However, some properties or protected areas could restrict the maximum share.

Was Shared Ownership always cheaper than buying outright?

It could reduce the initial mortgage and deposit. The complete comparison also needed to include rent, service charges, legal costs and future lease-related expenses.

Could a Shared Ownership property be rented out?

Most leases restricted subletting unless the housing provider gave permission. The buyer needed to check the lease before proceeding.
