Shared Ownership mortgages in London: what to know
Shared ownership lets you buy a share of a property, typically between 10% and 75%, and pay rent to a housing association on the remainder. You need a mortgage only on the share you are buying, so the deposit is far smaller than for an outright purchase. It is a common route into ownership in London for buyers priced out of the open market, but the leasehold terms and the cost of increasing your share deserve close attention.
- Your deposit is calculated on the share you buy, not the full property value, which is what makes the entry cost so much lower.
- You pay rent on the share you do not own, plus usually a service charge — so compare the total monthly cost against renting, not just the mortgage payment.
- Increasing your share is called staircasing. Each step involves a valuation and legal costs, and you buy at the current market value rather than the original price.
- Shared ownership properties are leasehold, and most are harder to resell than open-market homes because the buyer pool is smaller and often restricted.
What matters locally in London
The capital is really dozens of separate markets. Zone 1 and the prime central boroughs are dominated by flats and cash-heavy buyers; the inner ring — Hackney, Peckham, Walthamstow, Brixton — mixes Victorian terraces with converted flats and heavy first-time-buyer demand; the outer boroughs from Croydon and Bromley to Barnet and Bexley are where family houses and school catchments drive moves. Ex-local-authority flats are everywhere and are perfectly mortgageable, but a minority of lenders restrict them by block height, balcony access or the percentage of privately owned flats in the block. New-build towers along the river and in regeneration zones bring their own issues: service charges that affect affordability, and cladding and building-safety documentation that a lender will want to see before offering.
- Shared ownership and other part-buy routes. London has more shared-ownership stock than anywhere else in the UK, and only a subset of lenders offer mortgages on it, with their own rules on maximum share and rent-plus-mortgage affordability.
- Buy-to-let stress tests. London rental yields are compressed relative to prices, so buy-to-let purchases here frequently fail a lender's interest coverage test even when the property lets easily.
England
Buying here follows the England and Wales process: you pay Stamp Duty Land Tax on the purchase, with a surcharge on second homes and buy-to-let, and neither side is committed until contracts are exchanged. Most flats are leasehold, so the length of the lease, the ground rent and service charge, and any outstanding cladding or fire-safety paperwork all affect which lenders will accept the property as security. A broker will usually ask about the tenure before anything else when you are buying a flat.
How much Stamp Duty will I pay in London?
Purchases in London are subject to Stamp Duty Land Tax, which is charged in bands on the price you pay. First-time buyers get relief up to a set price, and there is a surcharge if you are buying an additional property such as a second home or a buy-to-let. Because the thresholds are changed at Budgets, check the current bands on GOV.UK, or ask your broker or conveyancer to confirm the figure for your purchase before you commit to a deposit.
Questions worth asking a shared ownership broker
- How much deposit do I need for shared ownership in London?
- Typically 5% to 10% of the share you are buying, not of the full property value. On a 25% share of a £250,000 property, a 10% deposit is £6,250 rather than £25,000.
- Can I buy more of my home later?
- Yes, through staircasing. You buy additional shares at the prevailing market value, so if prices have risen, the extra shares cost more. Some newer leases allow smaller 1% annual increments.
- Who is eligible for shared ownership?
- Generally households under an income cap, who cannot afford to buy outright locally. Some schemes give priority to existing social tenants, key workers or people with a local connection.
- Do all lenders offer shared ownership mortgages?
- No — it is a smaller specialist market, and lenders have specific requirements about lease length and the housing association's terms. This is one area where a broker familiar with the products genuinely narrows the search.
