What Is a Shared Ownership Mortgage?

If you’ve been saving for a home but don’t quite have enough for a full deposit, a Shared Ownership mortgage could be the key to getting started.

This part-buy, part-rent option lets you purchase a share of a property — typically between 25% and 75% — and pay rent on the portion you don’t own. It’s designed to make home buying more accessible, especially for those with limited deposits or lower incomes.

At Mortgage Bridge, we regularly help clients explore Shared Ownership as a practical first step toward full home ownership. Here’s how it works, who it’s for, and what to expect from the process.

How Does a Shared Ownership Mortgage Work?

With a Shared Ownership mortgage, you buy a portion of a property (usually a new-build or resale home from a housing association) and pay rent on the remaining share.

For example:

• You buy 50% of a £200,000 property = £100,000 mortgage.
• You then pay rent on the remaining 50% (£100,000) to the housing association.

Over time, you can choose to buy more shares — a process called “staircasing” — until you own 100% of the property.

💡 You’ll still need a mortgage for the share you’re buying, but the deposit and loan required are smaller than for a full purchase.

Who Can Apply for a Shared Ownership Mortgage?

Shared Ownership is available to:

• First-time buyers
• Previous homeowners who can no longer afford to buy outright
• Existing Shared Ownership owners looking to move
• Those with annual household income typically under £80,000 (or higher in some areas)

You’ll also need to:

• Have a good credit history (or manageable past credit issues)
• Be able to afford the rent and mortgage payments comfortably
• Have a deposit (from 0% to 5% of your share’s value, depending on the lender and scheme)

💡 Some housing associations even accept 0% deposits if the lender allows, so it’s worth checking eligibility early.

How Much Deposit Do You Need for Shared Ownership?

The deposit is based on the share you’re buying, not the full property value.

For example:

• Property price: £250,000
• Buying 40% share = £100,000
• 5% deposit = £5,000

Some Shared Ownership lenders now offer:

• 0% deposits with housing association approval
• 2.5–5% deposits for buyers with limited savings
• Larger deposits for lower monthly payments or improved rates

💡 At Mortgage Bridge, we help clients secure suitable Shared Ownership mortgages even with smaller deposits or previous credit challenges.

What Are the Main Benefits of a Shared Ownership Mortgage?

Shared Ownership can offer a more affordable route onto the property ladder for many first-time buyers and families.

✅ Smaller Deposit Required

You only need a deposit for the share you’re buying, not the total property value.

✅ Lower Monthly Costs

Combined mortgage and rent payments often work out cheaper than renting privately.

✅ Option to “Staircase”

You can increase your ownership share over time as your income grows.

✅ Flexibility to Sell

You can sell your share at any time. The housing association usually has the first opportunity to find a buyer.

What Are the Drawbacks to Consider?

While Shared Ownership can be a great stepping stone, it’s not right for everyone.

⚠️ Rent Still Applies

You’ll still pay rent on the unowned share, so monthly costs can rise if rent increases.

⚠️ Limited Providers

Only certain lenders offer Shared Ownership mortgages — though this is growing each year.

⚠️ Leasehold Properties

Most Shared Ownership homes are leasehold, meaning you may have service charges and lease conditions to manage.

⚠️ Costs When “Staircasing”

Buying additional shares involves valuation and legal fees each time.

💡 A broker can help you weigh up the long-term costs and decide whether this route suits your plans.

How to Apply for a Shared Ownership Mortgage

Here’s a step-by-step overview of how to start the process:

1. Check Eligibility

Review the scheme’s income limits and property requirements with your housing association or broker.

2. Get a Mortgage Agreement in Principle (AIP)

This shows how much you can borrow and gives you a realistic price range to work within.

3. Find a Property and Reserve a Share

Work with your housing association or agent to secure your preferred home.

4. Submit Your Full Application

Your broker will help prepare and submit your mortgage application to the most suitable lender.

5. Complete the Purchase

Once approved, your solicitor and housing association will finalise contracts, and you’ll move into your new home.

Can You Get a Shared Ownership Mortgage with Bad Credit?

Yes — many lenders are open to Shared Ownership applicants with less-than-perfect credit, especially if issues are historic or small in scale.

Specialist lenders can consider applicants with:

• Old missed payments
• Satisfied defaults or CCJs
• Completed IVAs or DMPs
• Limited credit history

💡 We’ve helped many clients with credit challenges secure Shared Ownership mortgages by matching them with flexible lenders.

---

What Happens When You Want to Buy More Shares?

Through staircasing, you can gradually buy additional shares of your property — usually up to 100%.

Each time you purchase more, your rent decreases accordingly.
You’ll need a valuation from a RICS surveyor to determine the property’s current market value.

💡 Some schemes now allow partial staircasing in smaller increments (from 5%) to make the process easier and more affordable.

---

Is Shared Ownership Right for You?

Shared Ownership is ideal if you:

• Have a limited deposit
• Earn a modest income
• Can afford monthly payments but not full property prices
• Want flexibility to buy more over time

It’s less suitable if you:

• Plan to move frequently
• Want a freehold property from the start
• Prefer not to pay rent alongside your mortgage

A conversation with a broker can help you understand whether Shared Ownership aligns with your financial and lifestyle goals.
