Shared ownership gets talked about a lot and understood a little. It sits somewhere between renting and buying, and the details matter far more than the headline. This guide covers who it suits, how the money works, and what to check before you commit.
What shared ownership actually is
With shared ownership, you buy a percentage of a home with a mortgage and pay rent to a housing provider on the share you do not own. You hold a lease, so the home is leasehold, and over time you can buy more of it.
The attraction is a smaller deposit and a smaller mortgage than buying outright. The catch is that you are paying three things at once: your mortgage, rent on the rest, and usually a service charge.
What has changed
Under the newer model, official government guidance sets the minimum initial share at 10%, down from 25% under the older standard model. This applies to homes funded through the current affordable homes programmes. Homes sold under earlier models keep the terms they were sold with, so always check which version of the lease you are being offered.
Buying additional shares, known as staircasing, has also become more flexible. The minimum staircasing purchase is now 5%, down from 10%, and in the first 15 years you can also buy small extra 1% shares each year. Unused 1% options cannot be rolled over to later years, so it is worth planning rather than assuming you can catch up later.
Who it suits
Shared ownership tends to work best for people who:
- Cannot raise a large enough deposit for the whole home
- Have a steady income that comfortably covers the mortgage, rent and charges together
- Plan to stay for several years rather than a few months
- Are not already owners (eligibility rules apply, and providers assess each applicant)

The monthly costs to work out first
Before you fall for the floor plan, build a proper budget. A shared ownership home usually involves:
- Mortgage payment: on the share you own, from a lender that accepts shared ownership
- Rent: on the share you do not own, typically set as a percentage of that share's value, and it can rise over time under the terms of your lease
- Service charge: for building maintenance, insurance and communal areas, and you pay this on the whole building cost, not just your share
- Ground rent: where your lease includes one, so check the ground rent terms
- Buildings insurance and utilities: the usual household bills
Ask the provider for a full breakdown in writing, including how and when the rent and service charge can increase. A mortgage in principle will also tell you early on how much a lender is prepared to offer.
Repairs: who pays for what
Shared owners are generally responsible for repairs and maintenance of the home, even though they own only part of it. The newer model adds a period of repair support for early years, where the housing provider helps with certain essential repairs. The precise scope, limits and length of that support are set out in your lease, so read that section closely and ask your solicitor to explain it in plain English.
Furry friends and other lease surprises
Leases can contain restrictions that catch people out, such as rules on pets, subletting and alterations. If you have a dog, cat or a plan to rent out a spare room, ask before you reserve. Better a slightly awkward question now than an unhappy surprise later.
Selling a shared ownership home
When you sell, the process is a little different from a standard sale. The housing provider usually has a period to nominate a buyer first, and if they do not find one, you can market the home more widely. If you own a larger share, you are selling a larger slice of the sale price. A conveyancer experienced in shared ownership is worth their fee, and our step by step conveyancing guide shows what to expect either way.
Questions to ask before you reserve
- Which version of the shared ownership lease is this?
- What is the initial rent, and how is it reviewed?
- What are the service charge, ground rent and any other fees, and how have they changed over recent years?
- What are my repair responsibilities and what support applies in the early years?
- What are the staircasing rules, and are there any fees?
- What are the rules on selling, subletting and pets?
The practical takeaway
Shared ownership can be a genuine route onto the ladder, especially with the lower minimum share, but only if the full monthly cost works for you with some room to spare. Run the numbers on mortgage, rent and charges together, read the lease with a specialist solicitor, and check what you can buy and sell later.
