They use an isolation membrane under tile in all the new houses today. They did not do that 15 years ago...
If it was mine, or if I wanted it to be mine, I would plan on re tiling that area (I would want new color and style, not match 15 year old tile) and put a isolation membrane down so the crack does not come back thru the new tile.

I agree with your comments, my initial response was for the inspection to determine the extent of any possible damage, but I completely agree with your comments about new tile and an isolation membrane. You are correct about matching 15 year old tile, and I did not even think about the old grout...
