How bad is this drainage on house we purchasing?

bbbuyer

It’s north east facing back and the drain itself is shaded most of the time.

It has green mossy bits, cracked and looks wet.
it takes kitchen, bathroom and kitchen roof wastewater and rainwater

That someone has poked a length of flexible pipe through the wall might suggest you are going to find a whole host of bodges problems with the property.

Generally drains/gulleys like that are best done away with because they cause nothing but problems - either getting blocked and/or smelling, or contributing to the adjacent wall getting damp.

Don't expect the vendor to knock a huge amount off the agreed/asking price though, it isn't critically important to deal with it, and the cost shouldn't be massive.

At least the general mess around the drain shows the vendor hasn't gone out of their way to spruce things up; you're seeing the place like it is.

The gully's the sort of thing I's still expect to see on 1930s properties, especially ones that haven't had much expended on them over the decades. Not much more can be read into it than that.
