How concerning is this issue?(See Pics)

[Joshua Meyers]

Found a pretty solid deal today and the seller seems motivated. The only problem I've found with the property is this crack/shift. There are no cracks in the walls and all the windows, doors, floors, etc. seem to all be level and close normally. How serious is this issue and can it be repaired? The house is approx 70 yrs old. I know it's hard to judge from pictures alone but I'm just looking for some general opinions. Thanks for the help guys!

a couple of things stand out to me .

Bottom picture : It looks like Slab walls under the Blocks has cracks and shifted . This would cause the Block joints to seperate and shift . also at top of blocks the Sill looks rotted and worn out 

middle picture : shows more Footing damage and Block seperation . Not sure on the Black pipe sticking out Not a dryer vent Possibly at one time Vent for a wood stove ?

top picture : looks like the continuation of the side 

guessing this caused by water and frost . also guessing there is just a crawl space and no full basement underneath ? If that is the case you are going to have to find either a structural engineer or a Foundation company that jacks up slabs and walls replacing the cracked blocks . If that is the case someone will have to have access to underneath the house to verify and foundation and check the sills 

realisticlly it ain't going to get any better . Might be a $3,000.00 job or a $20,000.00 job . What is the gutter situation on the house ? Not sure what part of PA. you are in but you want to make sure any Footings / new walls are at least 4 feet into the ground .
