Shared Ownership vs Buying Outright: Which Suits First-Time Buyers?

Understanding Your Two Main Routes to Homeownership

As a first-time buyer looking at new build homes, you have two primary routes onto the property ladder: buying outright (with a standard mortgage covering the full property value) or shared ownership (where you buy a share of the property and pay rent on the remainder). Both have their merits, and the right choice depends entirely on your financial situation, location, and long-term goals.

Shared ownership was specifically designed to help people who can’t afford to buy a home outright on the open market. It’s delivered through housing associations and is widely available on new build developments across England. If you’ve been looking at new build homes and feeling priced out, shared ownership could be the key that unlocks the door to homeownership. For a broader overview of the buying journey, see our complete guide to buying a new build home in the UK.

Buying outright with a standard mortgage is the traditional route and gives you full ownership from day one. You’ll need a larger deposit and higher income, but you won’t pay rent on any portion of the property and you’ll have complete freedom over your home. Understanding the new build buying process step by step will help you navigate either route.

How Shared Ownership Works in Detail

Shared ownership allows you to purchase a share of a property – typically between 25% and 75% – and pay a subsidised rent on the remaining share to a housing association. You take out a mortgage on your share and pay rent on the rest, making your monthly outgoings lower than if you were buying the whole property.

Eligibility Criteria

To qualify for shared ownership in England, you must meet the following criteria:

• Your household income must be £80,000 or less per year (or £90,000 or less in London)
• You must be a first-time buyer, or a previous homeowner who can no longer afford to buy, or an existing shared owner looking to move
• You must be unable to afford to buy a suitable home on the open market in your area
• You must not have any outstanding credit issues that would prevent you from getting a mortgage
• You must be able to demonstrate you can afford the ongoing costs (mortgage, rent, and service charges)

The New Model Shared Ownership (from 2021)

The government introduced the “New Model” shared ownership in April 2021, which includes several improvements for buyers:

• Initial share from 25%: You can buy as little as a 25% share (previously some schemes required higher)
• Staircasing in 1% increments: For the first 15 years, you can increase your share by as little as 1% at a time (up to 15% total in 1% increments), making it easier to gradually build ownership
• 10-year repair responsibility: The housing association is responsible for the cost of essential repairs for the first 10 years, up to a value of £500 per repair (capped at £1,500 per year)
• Longer initial lease terms: New shared ownership properties now come with a 990-year lease as standard

These improvements make shared ownership significantly more buyer-friendly than earlier versions of the scheme. For a deeper dive into shared ownership specifically for new builds, see our comprehensive shared ownership new build guide.

Understanding Rent on the Unsold Share

The rent you pay on the portion you don’t own is typically set at 2.75% of the value of the unsold share per year. This is usually below market rent, making it more affordable than renting privately. However, be aware that the rent can increase annually, usually in line with RPI (Retail Prices Index) plus up to 0.5%. Over many years, these increases can add up, which is why many shared owners aim to staircase to higher ownership levels or full ownership over time.

Monthly Cost Comparison at Different Share Levels

One of the most important factors in your decision is the monthly cost. The table below compares the typical monthly outgoings for shared ownership at different share levels against buying outright, based on a £250,000 new build property. These figures use a mortgage rate of 5% over 25 years and a shared ownership rent rate of 2.75% on the unsold share.

Important notes: These figures are illustrative and based on a £250,000 property with a 5% mortgage rate. Your actual costs will depend on the specific property price, mortgage rate, rent rate set by the housing association, and service charge. Always get a personalised affordability assessment before committing.

The Deposit Advantage

Perhaps the most striking difference is the deposit requirement. At a 25% share, you only need a £6,250 deposit compared to £25,000 for buying outright – that’s £18,750 less to save. This can cut years off your savings timeline, especially if you’re combining it with a Lifetime ISA. For more strategies on building your deposit, read our guide to saving for a new build deposit.

What About a £350,000 Property?

For those looking at higher-priced new builds, the numbers scale accordingly. Here’s how a £350,000 property compares:

Staircasing: Building Towards Full Ownership

One of the key advantages of shared ownership is the ability to staircase – gradually buying additional shares of your property over time until you eventually own it outright. Understanding how staircasing works is essential for making an informed decision.

How Staircasing Works

When you want to increase your ownership share, you apply to the housing association and have the property independently valued at current market rates. You then purchase additional shares at the current market value (which may be higher or lower than the original purchase price, depending on how the market has moved).

Under the New Model shared ownership (from 2021), you can staircase in 1% increments for the first 15 years (up to a total of 15% additional ownership through 1% steps). After that, or if you want to buy larger chunks, the minimum purchase is typically 5% or 10% depending on the housing association. You can staircase up to 100% ownership, at which point you own the property outright and no longer pay rent.

Costs of Staircasing

Each staircasing transaction involves costs including:

• Valuation fee: £200–£500 for an independent property valuation
• Solicitor fees: £500–£1,500 for the legal work
• Mortgage arrangement fees: If you need to remortgage to fund the additional share
• Stamp duty: May apply if you’re staircasing to 80% or above and the property value exceeds the relevant threshold. Our guide to stamp duty on new build homes explains the details

These costs mean that very small staircasing steps (1%) may not be cost-effective once you factor in fees. Many shared owners wait until they can afford to staircase by 10% or more to make the transaction costs worthwhile.

The Strategic Approach to Staircasing

The optimal staircasing strategy depends on property values and mortgage rates at the time. Here are the key considerations:

1. Property value appreciation: If your property has increased significantly in value, buying additional shares costs more. Some owners choose to staircase early while prices are lower
2. Mortgage rate environment: When mortgage rates are low, it may be cheaper to borrow more and staircase up. When rates are high, the combined cost of mortgage plus rent may be acceptable
3. Rent reduction: Each time you staircase, your rent decreases because the unsold share is smaller. This can free up money for further staircasing
4. Reaching 100%: Once you own 100%, you no longer pay rent to the housing association, your monthly costs may decrease significantly, and you have full ownership rights

Pros and Cons: A Direct Comparison

To help you weigh up both options, here’s a comprehensive comparison of the advantages and disadvantages of each route. Consider which factors matter most to your personal situation.

Which Option Is Better for Your Circumstances?

There’s no universally “better” option – the right choice depends on your individual circumstances. Here’s a guide to help you decide.

Shared Ownership May Be Better If:

• You have a smaller deposit saved (under £15,000) and want to get on the ladder sooner
• Your income is below £80,000 (£90,000 in London) and you’re priced out of the open market in your area
• You want to stop renting and start building some equity, even if it’s not on the full property value
• You’re happy to live in a specific development rather than having unlimited choice
• You see it as a stepping stone and plan to staircase to full ownership over time
• You’re currently paying rent that’s comparable to or higher than shared ownership costs
• You’re looking at an area where even with a Lifetime ISA and maximum savings, outright purchase is years away

Buying Outright May Be Better If:

• You have a sufficient deposit (ideally 10%+) for the properties you’re considering
• Your income comfortably supports a mortgage on the full property price
• You want maximum choice over location, development, and property type
• You prefer to build equity on the full value of the property from day one
• You want complete control over your home without housing association involvement
• You’re thinking long-term and want to avoid the ongoing cost of rent on an unsold share
• You may want to make significant modifications or improvements to your home

The “Wait and Save” vs “Get on the Ladder Now” Debate

One of the biggest dilemmas first-time buyers face is whether to use shared ownership to get on the ladder now, or wait longer to save a bigger deposit for outright purchase. Consider these factors:

1. Property price growth: If prices are rising in your area, waiting could mean the goal posts move further away. Getting on the ladder via shared ownership means you benefit from any future price increases on your share
2. Rent vs mortgage: Every month you spend renting privately is money going to your landlord with no return. Even with shared ownership, you’re building equity on your owned share. For a detailed comparison, see our renting vs buying analysis
3. Life stage: If you need stability now (starting a family, settling in an area), shared ownership can provide that sooner. If you’re flexible and happy renting for a few more years, outright purchase may be worth the wait
4. Career trajectory: If your income is likely to increase significantly in the next few years, waiting to buy outright might make sense. If it’s stable, shared ownership gets you started now

No matter which route you choose, improving your credit score beforehand will help you secure the best possible mortgage deal.

Frequently Asked Questions

Can I use a Lifetime ISA with shared ownership?

Yes, absolutely. You can use your Lifetime ISA funds (including the 25% government bonus) towards the deposit on a shared ownership property, provided the full market value of the property is £450,000 or less. Since the deposit required for shared ownership is much smaller, your LISA savings may cover the entire deposit. For example, a 10% deposit on a 25% share of a £250,000 property is just £6,250 – achievable with around 18 months of LISA savings and bonus.

What happens to my shared ownership home if I want to move?

When you want to sell a shared ownership property, the housing association typically has the right of first refusal for a set period (usually 8–12 weeks). During this time, they may find a nominated buyer (another shared ownership applicant). If they don’t find a buyer within this period, you can sell on the open market. If you’ve staircased to 100% ownership, you can sell freely without housing association involvement. The sales process is slightly longer than a standard sale, so factor this into your plans.

Is shared ownership only available on new build homes?

No, shared ownership is available on both new build properties and resale shared ownership homes (where a previous shared owner is selling their share). However, the majority of shared ownership stock in the UK is new build, as housing associations partner with developers to include shared ownership units in new developments. Resale shared ownership properties can offer good value and are worth considering alongside new builds.

Can I rent out a shared ownership property?

Generally, no. Shared ownership properties are intended to be your main residence, and most housing associations do not allow sub-letting without prior written consent. In exceptional circumstances (such as temporary work relocation), some housing associations may grant permission for a limited period. If you think you might need to move temporarily in the future, discuss this with the housing association before purchasing.

What are the income limits for shared ownership in 2025?

The current household income cap for shared ownership in England is £80,000 per year, or £90,000 per year in London. This applies to the combined income of all people who will be named on the mortgage. These limits are reviewed periodically by the government. If your income is above these thresholds, you would need to explore other routes onto the property ladder such as buying outright with available developer incentives.

Making Your Decision: Next Steps

Both shared ownership and buying outright are valid, well-trodden paths to homeownership for first-time buyers. Shared ownership offers an accessible entry point with a smaller deposit and lower income requirement, making it ideal for those who want to stop renting and start building equity sooner. Buying outright gives you full ownership, maximum flexibility, and no ongoing rent – but requires more savings and a higher income.

Whichever route you choose, the key steps are the same: start saving your deposit as early as possible, work on building a strong credit score, and research the developments and areas that interest you. If shared ownership appeals, contact local housing associations to register your interest and attend open days at shared ownership developments. If you’re aiming to buy outright, maximise your Lifetime ISA and explore mortgage options well in advance.

Remember, there’s no wrong answer here – both routes lead to the same destination: your very own new build home. The best choice is the one that gets you there in a way that works for your finances and your life.
