Should I buy a property with mice problem and likely mold in the basement?

[Sima Meh]

I have a ratified contract for a property. Among other things, the inspection showed signs of pest (mice) inside the attic space. (Tunnel holes in insulation and droppings). Also, the insulation in attic was noted as inadequate at the time of inspection. I guess the mice have chewed the insulation.

Additionally, the drywall at basement detected moisture. The repair work will likely involve the removal of drywall in order to
perform repairs. The extent of damage cannot be realized until the drywall is removed. The inspection also pointed out that the fungi growth should be checked once drywall is removed.

I am concerned about mice infestation and likely damage to electrical wires and wood because of that. There is no way to detect these damages unless something major comes up later. I am also concerned about possible mold in the basement.

What should I do? Ask the seller for repairs or walk away. Are these major problems?
