Let me see if I understand what you have: You have a crack on the South end of the home and then you have a corresponding crack on the North end of the as well?

Normally if you find a crack on opposing ends or sides of a home, the foundation had failed. It could be from heaving of the soil or displacement of the soil. Either way it is not normal.

I would not recommend or specify any repairs.

I would simply defer to an SE due to the conditions found. In my wording I would say something along the lines like this "Due to the wall and foundation cracks that I found, a structural engineer who specializes in residential foundations should take a look at the structure. If any repairs are deemed necessary the SE will be able to design those repairs."
