Stucco is not always made the same. However, it is a mix of plaster and cement. Sometimes pigment will be added to the mix and sometimes it will be painted later on. You should clean it as needed and should check the paint annually to see if it is peeling or cracking. Stucco will expand and contract in due to the temperature, sometimes creating minor hairline cracks in the stucco. You can fix these cracks with certain caulk or other flexible crack sealers to fill the gap. Brick and vinyl also need to be maintained in other ways. Don't let the stucco scare you away! Some other things you can do is speak to some contractors. Also, be sure to have your future home inspected. The inspector will be able to tell you how much work will need to be done to the exterior of the house as well as any other issues on the rest of the property. Good luck!
Stucco is an excellent material and very durable. Florida, a very hurricaine prone area, uses it on just about every house/structure that is built. Stucco is a cementuous finish that troweled on over lathe or to a base coat like cement block. Because it is made of cement it will withstand much more abuse than many other materials. It does need maintenance however and how often it needs to be painted depends on who you talk to. The answer to that questions is more a product of the paint used than the material it is applied to. Cheap paint means that you will need to paint more often, but that maintenance has little to do with subsurface beneath the paint. I hope that helps.
