Buyer guide
What is shared ownership and is it worth it?
Shared ownership lets you buy a share of a home and pay rent on the rest. It lowers the deposit and the income you need to get in, which genuinely helps some buyers onto the ladder. It also carries costs and constraints that are easy to underestimate, so it is worth understanding the whole picture before you commit.
How it works
You buy a share of a property, typically between 25 and 75 percent, with a mortgage and a deposit calculated on that share alone. A housing association or other provider owns the remaining share, and you pay rent to them on the part you do not own. Your monthly outgoings therefore combine three things: a mortgage on your share, rent on the unowned share, and a service charge. Because the deposit is worked out on the share rather than the full value, the cash needed to get in is smaller, which is the main appeal of the scheme.
Staircasing, and the trap
Staircasing means buying further shares over time, ideally working your way up to 100 percent ownership. The catch is that each additional share is priced at its market value at the moment you buy it, so if the property has risen in value, staircasing costs progressively more rather than staying at the price you first paid. Each step also brings a valuation fee, legal costs, and sometimes a mortgage change. The plan to staircase to full ownership is perfectly reasonable, but rising prices and repeated fees can make it slower and more expensive than buyers assume at the start.
The real monthly cost
Add the mortgage, the rent on the unowned share, and the service charge together to see the true monthly figure, rather than looking at the mortgage alone. Rent on the provider's share is often set at up to around 2.75 percent of that share's value per year and usually rises each year under the lease terms. Because you are effectively paying both rent and a mortgage at the same time, the combined monthly cost is not always lower than renting outright, or than a mortgage on a small full-ownership home, so compare the totals carefully before deciding.
Most schemes are leasehold
Shared ownership homes are almost always leasehold, which means everything covered in buying leasehold applies here too: the lease length, the service charges, and the relationship with a managing agent and freeholder. On many schemes, particularly older ones, you can also be responsible for all repairs and maintenance to your home even though you do not yet own all of it. Read the lease and the repair obligations closely, because the split between what you pay for and what the provider covers is not always what new buyers expect.
Selling can be harder
When you come to sell a shared ownership home, the provider often has a fixed period in which to find a buyer first, before you can market it more widely. The pool of buyers is also smaller, because they generally have to qualify for the scheme on income and other grounds. Together these can make selling slower and less flexible than an ordinary home. This is not in itself a reason to avoid shared ownership, but it is a reason to go in expecting less freedom to sell quickly than full ownership would give you.
Stamp duty choices
Stamp duty on shared ownership is more involved than on a standard purchase, and you usually have a choice. You can elect to pay stamp duty on the full market value of the property up front, even though you are only buying a share, or you can pay in stages as you staircase, starting with the duty on your initial share. Each route has trade-offs depending on the price and how much you expect to staircase, so it is worth getting advice and running the numbers before you decide which election suits you.
When it makes sense
Shared ownership can work well when it is the realistic route into a home you would otherwise be priced out of, when you plan to stay put for several years, and when you have understood the combined monthly cost and the constraints on selling. It makes much less sense if you could instead stretch to a small full-ownership home, or if you expect to move again soon and would be hit by the selling restrictions. Run the full numbers, including rent, service charge, and stamp duty, before treating it as the cheaper option.
