Question regarding stucco homes

[Matthew Byers]

Still in the hunt for some decent property buying but my lack of understanding has me worried I may pass up some good deals. Here's the situation. House for sale that comes with a in-law suite (I'm looking for rental property I can also reside in). The house is an older model stucco but has had some updates. My question (s) revolve around not knowing much about stucco in general.

The house does not have central air/heating which to a noobie like me seems just crazy but I'm hearing that stucco really doesn't require central air/heating as conventional homes do, this accurate?

Second, how does the maintenance work on such homes? Meaning does painting work the same, roofing require special steps? 

Thanks for any replies as always folks. Links, search tips, etc are especially always welcome, learn to fish versus being given one and all...
