Shared ownership valuation: other nearby SO properties

Svenena

I'm thinking about selling my shared ownership house, and the first step will be getting an independent valuation. There are other, identical, shared ownership houses on my street, which will obviously be the best comparables for the surveyor to use, but I'm just wondering how a valuer would know what percentage had sold of those houses. Eg, I own 50% of my property, so that's what I'd be selling. If a house on the street had sold 40% or 60% of a property, how would the surveyor know this? Is the percentage sold recorded on the Land Registry?
Similarly, if a neighbour had staircased, is that recorded on the LR differently to a sale? Actually, I don't even know if staircasing transactions are recorded by the LR?

A valuation is of the property. It has nothing to do with ownership. If yours is a 2 bed house he will take into account previous selling prices/worth of other similar 2 bed houses nearby, regardless of how they are owned.

Sure, but if the only properties near me that have sold were shared ownership, would the surveyor know that? Let's say only two properties within five miles of me had sold within the past couple of years, and both were shared ownership and had only sold 25% of their properties, and I was wanting a valuation in order to sell 50% of my property. Would the surveyor know that those previous sales were for a smaller proportion than mine? Because the price that's recorded on the LR is the selling price of the proportion sold, not the overall value of the property.

Any surveyors able to offer an insight on this?

I’ve got experience of this as I previously lived in a shared ownership house and had it valued when I sold it. 
They determine the value of the whole property as mentioned in the other reply. So for example, when I purchased my house originally it was a 40% share. The whole house was valued at 155k and so my 40% share was 62k. When I got it valued 5 years later the valuer looked at general market increases in that 5 years and determined that my whole property was then worth 169k and so the 40% share was determined for the new buyer as 67,600. 
He didn’t look at what other SO property sale prices were in terms of the shared value because it would be impossible for him to know what % of them was owned. Instead he told me he looked at the original purchase price, the general % of house price increases in the area during that time and the full sale prices of comparable properties.

Round here shared ownership houses literally fly out immediately - 
they are so rare on resale 

the surveyor prices the whole house. Dont worry he wont think yours is less because those who paid for a 25% share dont effect the price of the whole. They all know the proper value of the whole house 

So for example everyone knows in this area a two bed goes for around £350k 

thats what the surveyor would value the whole as and someone having a 25% share owns and sells at £87500
someone with 40% sells at £140k for that share 

But the house is always £350k as a whole
