Vertical crack between windows - picture

[climbelon]

I am looking to make an offer on a top floor flat in a 3 storey 1930s house conversion. There is a vertical crack which appears to go from top floor window to 1st floor window, seen over the wall from the alley behind the house (the flat does not include access to the garden). Any advice from the photos? Would a surveyor look from the alley or only at the areas accessible from the house?

There are also cracks in the ceiling of the front room which on their own don't seem like a problem from my Google research, but I have included a picture in case relevant.

Thanks

I literally can't see what you're referring to in either of these pictures OP. Do you have anything clearer??

I can't see any crack either

Thanks for your replies, it posted 2/4. This any clearer?

And ceiling

Do you mean the crack going from the top window to the bottom?

I see what you mean - the quality seems to have reduced. Attached are the same photos zoomed in, hopefully will be clearer.

Could be movement on the property. What is that wall?

It looks like the windows used to be bigger, but they filled in the bottom 18 inches. Would I buy that flat? No. There's no access for remedial work, and that really steep slope would give me concerns about ground movement.

I would be more concerned about buying a house on a cliff edge 🤨

That would have to be a hard no from me also.
Why has it caught your eye? Is it extremely cheap or something?

The crack from the window ledge to the ground could be subsidence, but you'd need a specialist surveyor to confirm that. The cracks in the ceiling could be because of water damage from above.

Whatever caused it, I wouldn't touch it.

Pretty much, affordable in a nice area. Thanks for the feedback, hadn't thought about the implications of the slope!
Landlord who is selling the flat owns the other two so would presumably allow access to the garden for works. If that's what you meant @theboffinsarecoming
The wall is between the garden and the alley.

Is the outside wall south facing? Obviously the render covers whatever, but we had a vertical crack on our old house, going through the cement and brickwork as it went down. Had a structural survey on it and it was confirmed as thermal movement. It never changed in 16 years and I know it didn't come up on our purchaser's survey.

This.

No way would I touch that with a barge pole.

Yes the back is south facing

Is this because of potential subsidence?
