Shared Ownership is a government-backed scheme where you buy a share of a property (typically 10–75%) and pay rent on the rest. It's designed to help people who can't afford to buy outright, and it has a lower deposit requirement than a conventional purchase. But it comes with significant complexities that buyers often discover after moving in.
How Shared Ownership Works
- •Buy 10–75% of the property
- •Pay rent on the unowned share (typically 2.75% of its value per year)
- •Smaller deposit required: 5–10% of your share
- •Staircase to 100% ownership over time
The Pros
- •Lower deposit threshold — get on the ladder sooner
- •Monthly costs (mortgage on share + rent) often lower than full market rent
- •Build equity through staircasing
- •Government-backed — new builds typically well-maintained
- •Useful for high-value areas where outright buying is impossible
The Cons (Often Underexplained)
- •Rent increases: rent is typically reviewed annually at RPI+0.5% — can increase faster than income
- •Service charges: leasehold buildings have service charges (£150–£500+/month) with limited accountability
- •Ground rent: some older shared ownership leases have onerous ground rent provisions
- •Staircasing costs: each tranche purchase has legal fees and new mortgage costs
- •Difficult to sell: selling a shared ownership property is more complex than conventional; housing association has right of first refusal
- •Maintenance obligations: you typically pay full maintenance costs even on shares you don't own
Is It Right for You?
Can I sell a Shared Ownership property at any price?+
You can sell at any time, but the housing association typically has a nominated period (4–8 weeks) to find a buyer at the assessed market value first. If they can't find one, you can sell on the open market — but only your share.
What happens if property values fall in Shared Ownership?+
You own a share of the property, so a 10% fall in value reduces the value of your share proportionally. The rent you pay on the unowned share may not reduce. This means negative equity is possible on the mortgage for your share.
