Yes an inspection was done. He did metion the cracks due to settling
but I'm pretty sure settling is much different then sinking. I have a
friend who works for city hall and advised me that there is a whole
file on my house and letters that the seller wrote to the city
indicating this problem and seeking assistance from the city. So the
sellers knew however on all the forms that they had to mention of
problems the house had, they failed to mention any of this. I am so
completely upset.

Thanks for your response!!!

Well, there you go. Now all you have to do is
track down an engineering company that can design,
price, and execute a fix, locate the sellers,
and sue their ass to pay for it. No problem.

(You didn't buy the house "as is", did you?)
