Shared Ownership Mortgage Advice

Shared Ownership Mortgages

Shared ownership allows you to purchase a share of a property — typically between 25% and 75% — and pay subsidised rent on the remainder to the housing association. You take out a mortgage on the share you buy, not the full property value. This reduces both the deposit required and the monthly mortgage payment, making homeownership accessible on incomes and savings that the open market forecloses.

How the Shared Ownership Mortgage Works

On a shared ownership purchase of a 320,000 property at a 50% share, the mortgage is on 160,000 — not 320,000. A 10% deposit on your share is 16,000. The mortgage payment on 144,000 at 4.5% over 25 years is approximately 800 per month. You also pay subsidised rent on the unsold 50% share, typically 2.75% per year of the unsold share value — around 366 per month on a 160,000 unsold share. Total housing cost: approximately 1,166 per month, versus approximately 1,400 to 1,600 per month to rent the same property outright.

The mortgage on a shared ownership property is specialist by definition: standard residential mortgages do not cover shared ownership. Lenders on the shared ownership panel understand the lease structure, the staircasing provisions and the specific requirements of housing association ownership. We identify lenders who offer the most competitive rates on shared ownership mortgages specifically.

Staircasing — Buying More Shares

Shared ownership allows you to buy additional shares over time — a process called staircasing. Typical minimum staircase purchase: 10% of the full property value. Each staircase purchase requires a new mortgage to cover the additional share, or remortgage of the existing one to release capital. Once you own 100% you own the freehold outright and the subsidised rent ends. We advise on the staircasing mortgage alongside the initial purchase mortgage, modelling the financial position at each staircase step.

Shared Ownership Example	25% Share	50% Share	75% Share
Property value	£320,000	£320,000	£320,000
Your share	£80,000	£160,000	£240,000
Deposit (10% of share)	£8,000	£16,000	£24,000
Monthly mortgage (4.5%, 25yr)	£400	£800	£1,200
Monthly rent on unsold share	£550	£367	£183
Total monthly housing cost	£950	£1,167	£1,383

Shared Ownership Eligibility

The government’s shared ownership scheme is available to first-time buyers, previous homeowners who cannot afford to buy on the open market, and people who have a long-term disability. The income threshold is typically 80,000 per year (or 90,000 in London). The property must be a new build from an approved housing association, or an existing shared ownership property being resold. We confirm eligibility and scheme compatibility before any application is made.

Hampshire and Surrey Shared Ownership Availability

Shared ownership properties are available across our coverage area from housing associations including Sovereign, Vivid Housing, A2 Dominion and Radian. Active developments include properties in Basingstoke, Farnborough, Aldershot, Fleet and the new Manydown Garden Town development. We maintain awareness of available shared ownership stock and can advise on the mortgage for any specific development or resale property.

Getting the Right Mortgage for Shared Ownership

Shared ownership mortgage rates are slightly higher than standard residential rates because the leasehold structure and housing association involvement require specialist lenders. The difference is typically 0.2% to 0.5% above equivalent standard residential rates. The reduction in deposit and monthly commitment more than compensates for this in the vast majority of shared ownership cases. We compare all available shared ownership mortgage products and confirm the best available rate for your specific share size, income and property before any application.

Shared Ownership vs Open Market — The Financial Comparison

For buyers whose income supports shared ownership but not a full open market purchase at the target location, the comparison is direct: shared ownership now versus open market in 3 to 5 years after further saving. The cost of delayed ownership — rent paid while saving — often exceeds the cost of the shared ownership premium in the medium term. A buyer renting a 3-bed Fleet property at 1,600 per month for 3 years pays 57,600 in rent while saving the additional deposit needed for the open market. Shared ownership of the same property type at a 50% share at 1,167 per month total housing cost produces 14,868 less outgoing over the same 3 years, while building equity through mortgage repayment.

The Resale Process for Shared Ownership

When you sell a shared ownership property, the housing association has a nomination period — typically 8 weeks — during which they can find a buyer for your share. If they find a buyer, the sale price is set by an independent RICS valuation. If they cannot find a buyer within the nomination period, you can sell on the open market. This process is straightforward but requires understanding before purchase. We explain the resale implications of the specific housing association’s lease as part of the advice process.

Common Questions

Client Reviews

What Our Clients Say

★★★★★

"Shared ownership was the only route to homeownership that worked for our income. Localnest found us a rate we couldn't have got from the housing association's recommended lender and the whole process was straightforward."

Emma and Liam T. · Basingstoke, Hampshire

"I didn't realise shared ownership applied to resale properties as well as new builds. Localnest explained the options, found the mortgage and coordinated with the housing association throughout. No broker fee, as promised."

Nadia F. · Farnborough, Hampshire

"Staircasing from 50% to 75% with Localnest was simple — one call, one application, completed in 6 weeks. The same process I'd expected to be complicated was handled without any drama."

Rob M. · Fleet, Hampshire
