How does shared ownership work?

[nextsteps29]

For example, if a property has a 33% share rate at 50K, and I was able to purchase this outright, would I just be paying the rest as agreed rent on the property until it was paid off and I then received full ownership?

Would I still need credit checks etc? My credit history isn't great at all, but I do have a small chunk of capital to purchase a shared ownership outright.

Keen to get onto the ladder somehow. Thank you!

Yes you would pay rent to council/HA (whoever is the shared owner) then have the option to buy the remaining 66ish % if you never want to you don’t have to but will never own the property and always pay them rent.
Remember that as a shared owner (even if your share is minimal/smaller in %) you will be responsible for ALL maintenance costs of the property unless your shared owner agrees to an ‘initial repair period’ also maintenance costs if there are communal areas/grounds upkeep.
so in effect the sooner you buy all the shares (100%) you won’t benefit apart from having a roof over your head … it’s a good way to get on the property ladder but not as cheap and easy as most think.
You will always need credit checks for buying property but it may be easier if you are a cash buyer?

No. You would buy a percentage (and they would expect you to buy the highest % you can afford, including with a mortgage not just whatever cash savings you have) and then you would pay rent on the percentage you don't own.

You will never own the property outright unless you later buy the remaining %. And the cost of that is based on the value of the property at the time you buy more if it, not the original value. So if the property increases in value, it will cost more to buy the remaining part.

Also, if you do buy an extra % in future (called staircasing) you have to pay for the property to be valued and conveyancing costs. You can't just say, here's £20k, please transfer an extra % to me.

So, as I understand the rent you pay to the council/HA does not go towards you paying off the property? It's simply a fee for being in that property. And if you want to purchase the remaining to have full ownership you would need to either get a mortgage OR simply pay it off in cash as you go along?

Sorry for all the questions, just trying to really understand it.

@nextsteps29 correct your rent will never be paying off any remaining balance. it is purely an income to the shared owner… as long as you don’t own the entire 100% you will always have your pay rent to the other shared owner but the rent can increase along with inflation rates and as @zzplec said above if you do buy an extra % in future (called staircasing) you have to pay for the property to be valued and conveyancing again each time you buy part ….so the sooner you get the extra funds to cover the remaining % less fees involved

You really need to do your research, especially as (from what I can gather) the initial full cost is inflated compared to similar properties, and usually you are buying new (new home ‘premium’).
Here’s a couple of tales of woe.

So you do get a roof over your head, however you have all the disadvantages of ownership, all the disadvantages of being a tenant, and all the disadvantages of leasehold.

Have a look on Reddit in their r/ukhousing and r/ukpersonalfinance forums.

It's not just SO properties where service charges have escalated sharply. It's a feature of older leasehold properties in general.

The SO model has improved in relation to lease length and how repairing works: https://www.sharetobuy.com/shared-ownership/introducing-the-new-shared-ownership-model/

And, actually, you don't have all the disadvantages of being a tenant, the one big thing which can't happen is being turfed out with two months' notice. (There are ways you can forfeit the lease, but they're few and far between!)

Ultimately, you need to do your research and decide if it's right for you. If it's the only way you can afford to buy, then potentially a good choice. (You do have to buy the maximum you can afford, so if you can afford more than the 33%, you'll have to do that.)

Yes, as pp said, you pay mortgage on the percentage you've bought, in this case 33%, and because you don't own the other 67% you pay the Housing Association rent, as they do own it. If you can buy the 33% outright, it might be worth seeing if you can buy more initially, through a mortgage. The more you own, the less rent you pay.
Make sure that the property allows you to buy 100% if you wish and doesn't have a cap, for example, at 80% ownership. That way you can staircase as the years go on, finally, if you want, owning 100%, which would mean that you would own it (albeit paying mortgage on it) and the Housing Association wouldn't own anything.
The Housing Association does checks on you, including checking that you don't earn too much. And your mortgage lender will do the normal checks.
Over the years, the rent can go up, but that would depend on their share.
It does have it's downsides, but I think it is a good way to get on the housing ladder.

I have lived in shared ownership for 20 years the only down side for me is that the house value is 4 x when it was purchased so I will never be able to buy anymore shares so will never own it completely so will be still paying the rent when retired. Even though the value of the owned part has gone up I still wouldn't be able to buy anywhere elsewhere as prices are so high or get a mortgage as I am near retirement age.
