What are the main disadvantages of buying a Shared Ownership property?

Even if you are eligible for Shared Ownership, not all lenders offer mortgages for Shared Ownership homes.

Once moved in, you won’t be able to make any major changes or improvements unless it’s stated you can in the lease and you have permission from the landlord.
If you decide to sell before owning 100% of a Shared Ownership home, the housing association has the right to find you the buyer. And even once you own 100% of it, you may have to give the housing association first refusal when you come to sell.
