This is not a surprising find....quite common. Mulligan is correct....but while I agree what he said IS the best practice, (i.e., relief cuts, slow curing, etc), this is not done typically in The Villages....thus the common finding of cracks in the grout, etc. That being said, when I do concrete work I always add relief cuts, wet down the slab for days, etc. A builder under time constraints, etc, sadly does not do this.
USUALLY, this is not a problem. If the crack is more open and wide, if it is larger in one area than another, if there is a difference in both sides, (i.e. differential cracking) then it may be a concern.
The fact is if you took up the tile or carpet, etc, you would most likely see shrinkage cracking all over your slab. Sometimes folks repair these but honestly, they are in many slab homes and they are not even known about or problematic.
If the seller filled these cracks as normal maintenance the potential buyer would not even know about it and it would not be an issue.
Basically, if they are hairline cracks, even on both sides, etc, it is usually construed as a cosmetic issue.
