In Sun City and Sun City West besides Single Family Homes, there are attached homes. We have Patio Homes and Apartment Style Flats and a few others. The most common (and popular) are the Gemini Twin Homes. These are two homes with one common wall. The attached homes belong to individual Home Owners Associations and pay a monthly fee whereas the single family homes rarely have a monthly HOA fee. Those fees cover different things in different HOA's. Usually they cover maintenance of the common areas and outside of the buildings, water, trash pick-up and then sometimes the roof or sewer line to the street. If you're looking at attached homes you should check to make sure they allow pets or if it's an investment make sure the HOA allows units to be rented. Make sure you work with an agent who knows the area, I can help you!
