Stucco has been problematic in the past; I recall a Pulte home that the builder had to remove the original materials and put in a newer stucco material. When was the home built? I would suggest a stucco inspection to make sure that there are not current moisture issues.
I would suggest you have a stucco inspection done. The maintenance is pretty low although stucco can develop cracks that would need professional repair. The maintenance is typically as simple as cleaning to maintain the great look and making sure all of the caulking is in good condition.
