thanks for the reply

The houses I've looked at are quite old, maybe from the 60s / 70s, and from what I've read cracks are inevitable with older properties, but I guess I just wanted to make sure I'm not going to have major issues down the track.

Would people generally avoid properties with larger cracks all together, or does it really depend on the building inspection? 

or on the contrary, have people bought houses with cracks and it hasn't caused any significant issues?
