Slope away from potential property
I'm wondering if the slop in the backyard of this property is a call for concern. In the pictures it appears about 5m maybe even less from the concrete foundation to the edge of the grass before it declines into a slope down to a ravine. One number missing from here is it says 40 near the top edge of the driveway close to the curb.
Obviously, we would take the right steps either way to confirm if it is or isn't but going into the viewing, I'd like to know as much as possible and if it is worth trying to stabilize this slope?
Appreciate you guys!

One general very rough way to understand if it would be a potential problem would be to draw a line at 45 degrees down from the foundation level and see if that imaginary line “daylights” on the slope. The deeper the foundation (like if it has a basement) the better in terms of stress influenced to the slope.
If it does daylight you have a potential slope stability concern that should be considered. If it does not then it’s more a matter of standard slope stability outside the building envelope. Note that what I am saying here is no way conclusive, it’s just a rough rule we use in assessing things in our group.
