Hello everyone. Shared ownership tenant here. This is what I know about the scheme. I hope this is helpful for you all :)
Firstly, shared ownership is not ownership. All you are buying is an assured tenancy for the duration of the lease. This means that if you get into eight weeks arrears with either your rent or your service charge, the housing association can and will take you to court. The law gives the courts no choice but to allow a repossession order - the HA will take the entire flat back, and will not give you back the money you paid for your share, much less the value of the share at the point the repossession takes place.
Secondly, rent and ground rent will go up as per the terms of your lease, and any changes in the law around rent do not usually apply to shared ownership properties. Housing Associations can charge pretty much what they want.
Thirdly - service charge is mandated under the terms of the lease, but the level of service is not. You will not be given a service level agreement. This means that you will have to pay service charge which can frequently escalate rapidly for little or no apparent reason, but the service you get in return is likely to be variable at best, and non-existent at worst. It is routine for housing associations to be lax about repairs and maintenance of their properties, and their complaints procedures often fail to resolve tenant issues satisfactorily. So, if tenants wish to complain they have to take legal action for breach of lease. If you take legal action, there is no mechanism by which any judgement you may win can be enforced, and it is possible that the HA can add their legal costs to your service charge going forward. Service charge in residential buildings is entirely unregulated, in both housing associations and in the private sector.
Points Four and Five - Staircasing and lease extensions.
Every time you staircase you have to go through the same process and you did when you bought your first share. You must pay your own legal fees, and, as far as I know, those of the housing association too.
You buy a share at the current market rate, and unless you staircase to 100% you still just have an assured tenancy.
Lease Extensions. Shared Ownership flats usually come with a relatively short lease, 99 or 125 years. Once a lease gets below 80 years, most lenders will not give a mortgage on it. So, if you want to retain the value of your shared ownership investment, you will need to extend the lease. Shared Ownership lease extensions are not subject to statutory lease extension in the same way that private residential leases are. So, you will have to negotiate with the HA, and rely on their good will in terms of the clauses they include. You must pay their legal fees and yours. The marriage value (ie the amount you must pay on top of legal fees for a lease extension) is determined by the length of the remaining lease - the shorter it gets, the higher the cost. It can be up to £20k or more once your lease gets close to 80 years.
And then we get to housing associations themselves. They are not charities, whatever they may say. They are "registered societies" - which means that they are regulated by the FCA, not the Charities Commission. The FCA does absolutely nothing in terms of regulating housing associations. There is also the Regulator for Social Housing, which is a government quango that regulates housing associations, and this is necessary because of the amount of public money they receive. The government sets out the terms under which the RSH operates, and they, literally, can do nothing unless and until there is a direct risk to life. For everything else, the RSH is very hands-off. The Housing Ombudsman will investigate complaints if you have exhausted the HA's own complaints procedure, and have also written to your MP. However, HAs will shut down a complaint without ever investigating whether they have addressed it, so oftentimes a complaint against a HA ends up going full Kafka without anything getting resolved. All of this means that Housing Associations are, pretty much without exception, awful organisations. If you put [name of any housing association +review] into google, you will see what I mean. There may be good ones, but they are generally few and far between.
I hope this information is clear but please feel free to come back to me if you have any questions, and I'll try and answer them as best I can :)
