It wouldn’t have been a main road when the steps were built though.
as said, I think with what looks like a gate once there at rhe back between the two houses and shared septic. This was adult kid lived next door to parent (s), parent has passed away, adult kid just kept it and is now selling very reluctantly .
Adult kid still there and has all the creepy signs and even postbox on gate so the postie doesn’t come in, adult kid has let it become delapidated.
I don’t think it will sell , because the agents disclaimer about not accepting offers tells us this sale is about much more than just money .
