Guide to Co‑Ownership in Northern Ireland

Co‑Ownership in Northern Ireland:
a practical guide for first‑time buyers

Co‑Ownership is Northern Ireland’s shared ownership route where you buy the share of a home you can afford (often with a mortgage) and pay rent on the remaining share owned by Co‑Ownership. It can be a realistic way to get on the property ladder if buying outright isn’t currently affordable, but it’s important to understand the limits, costs and steps before you apply.

Co‑Ownership NI: key facts at
a glance

Property price cap: there’s a maximum property value limit for Co‑Ownership purchases (currently shown as £210,000 on NI Direct).
Starting share: you can usually start by buying 50% up to 90% of the property price (based on affordability).
Buying out: you can increase your share later in 5% chunks (often called “buying out”).
Rent: you pay rent on the share Co‑Ownership owns, and it’s reviewed annually.
Fees: NI Direct states there’s a £100 application fee and, if successful, a £575 fee covering the property survey and some legal fees.

What is Co‑Ownership in Northern Ireland?

If you want to buy a home but can’t afford to buy without help, Co‑Ownership may be an option. NI Direct describes it as buying a share of the property and renting the rest from Co‑Ownership, a registered housing association.

The Northern Ireland Housing Executive summarises it simply: you buy the share you can afford now, Co‑Ownership covers the rest, you pay the mortgage on your share and pay Co‑Ownership rent on theirs — and you can increase your share over time if you choose.

How does Co‑Ownership work?

Think of Co‑Ownership as a “split” home purchase:

You buy a share of the property (commonly 50%–90%), typically using a mortgage.
Co‑Ownership buys the remaining share.
You then have two regular housing costs:
- Mortgage payment on your share
- Rent on Co‑Ownership’s share (reviewed yearly)
Over time, you may be able to increase your ownership in stages (often 5% at a time) until you own more — potentially all — of the property.

What homes can you buy with Co‑Ownership?

According to the Housing Executive, you can choose a new build or existing property anywhere in Northern Ireland, as long as it’s within the scheme’s maximum property price limit (noted as £210,000 on the page).

Co‑Ownership also decides whether a property is suitable for buying through the scheme (NI Direct notes that there are conditions a property needs to meet).

Who is Co‑Ownership for?

NI Direct frames eligibility around two key ideas:

You need to show you can afford the payments involved in buying a property.
You need to show you don’t have an alternative, unassisted route into home ownership.

The Housing Executive also notes that while the majority of Co‑Owners are first‑time buyers, people who have owned a house before can also apply in some cases.

Do you need a deposit for Co‑Ownership?

NI Direct states Co‑Ownership doesn’t ask for a property deposit, but your mortgage lender might — which is a really important distinction.

In practice, that means your deposit requirement (if any) is driven by:

the lender’s criteria,
your credit and affordability,
the property and loan size.

If you want to get a quick feel for repayments before you go deeper, you can use the Mortgage Calculator.

What other costs are involved?

Even though Co‑Ownership can reduce the size of the mortgage you need, it is still home ownership — and NI Direct explicitly lists common owner‑occupier costs you’ll be responsible for, such as:

insurance
rates
service charges
maintenance and repairs

It’s worth building these into your monthly budget before you commit.

Also, depending on the purchase price and your circumstances, Stamp Duty Land Tax may be relevant for buyers in England and Northern Ireland (rules vary). If you want a quick estimate, use the Stamp Duty Calculator.

Co‑Ownership fees: what to expect (as a starting point)

NI Direct sets out two fees during the process:

You apply online and must pay a £100 application fee (and NI Direct states it isn’t refundable).
If successful, NI Direct says you pay a £575 fee for the property survey and some of your legal fees.

Always check the latest scheme documentation and confirm costs before you proceed, because fees and requirements can change.

Step‑by‑step: how to apply for Co‑Ownership (simple version)

1. Get clear on affordability

Before you apply, work out what you can comfortably afford each month, allowing for:

mortgage + rent,
bills, rates, insurance,
and a buffer for life (car costs, childcare, etc).

2. Understand your mortgage options for your share

You’ll typically need a mortgage for your portion of the home, so a lender will assess income, outgoings and affordability — just as they would for a standard purchase.

If you’d like specialist guidance tailored to your situation, start with First-Time Buyer Mortgages.

3. Apply to Co‑Ownership

NI Direct states the application is made online and includes the £100 application fee.

4. Choose a suitable property (within the cap)

The Housing Executive notes the property needs to be within the maximum property price and that Co‑Ownership will look at suitability.

5. If approved, progress survey + legal work

NI Direct describes the £575 fee at this stage for survey and some legal fees.

6. Complete and move in

Once approved, mortgage arranged and legal work completed, you move in — with a mortgage on your share and rent on the remainder.

Co‑Ownership vs FairShare: what’s the difference?

Northern Ireland also has FairShare, another shared ownership route.

FairShare describes itself as a shared ownership scheme where homebuyers buy a share of a new‑build property (and pay rent on the rest). FairShare’s eligibility page also includes criteria such as not owning a home in the UK or abroad, and (typically) buying a new‑build property with a full purchase price not normally exceeding £160,000 (per the scheme’s wording).

A simple way to think about it:

Co‑Ownership: new build or existing homes (within the cap) across NI.
FairShare: focuses on new‑build properties (and outlines specific qualifying criteria).

Both can be helpful — the “right” choice depends on availability, eligibility, your budget, and how you want your home ownership journey to look.

Common pitfalls (and how to avoid them)

Underestimating monthly costs

Mortgage + rent is only part of the picture. NI Direct is clear you’ll still be responsible for ongoing ownership costs like insurance, rates and repairs.

Leaving mortgage prep too late

Because your lender may still want a deposit and will assess affordability, it’s wise to prepare early and have documents ready.

Not planning your “buying out” strategy

You don’t have to increase your share immediately — but if full ownership is your long‑term plan, it’s worth mapping out what would need to change (income, savings, childcare costs) to make that realistic.
