I left Danville about 12 years to work for the Del Webb communities in Northern California. Sun City Roseville was the first non-desert community built by Del Webb and was started in 1994 and sold out in 2000. There are 3100 homes with a golf course and all the phenomenal clubs and interest groups, as well as fitness, tennis, restaurant and everything you have come to expect from a Del Webb.
Sun City Lincoln Hills is approximately 6 miles away in the town of Lincoln and we started selling homes in that community from mid 99 to 2006. This community is 7000 homes and has 100,000 square feet in clubhouse amenities, as well as tennis, bocce, baseball diamond and a golf course. Are you a golfer? The costs are different in each Sun City since Roseville owns their golf course and Lincoln is open to the public with special rates for homeowners.
The third option is also in Roseville and it is a smaller non-golf course community which has about 900 homes and is a fairly new concept for Del Webb. It is called "The Club". The Club opened in 2005 and is still selling new homes, so you could qualify for the State Stimulus Credit (if the funds are available) if you purchase a brand new home.
A good plan would be to have a tour of each community to see where you feel most comfortable. The best part of all three is that you are close to medical facilities, shopping, theatres and restaurants with all three communities. I have worked in all three communities and would be happy to answer any questions you may have.
