The home you linked to is a newly constructed home that just went under contract. Wentworth Hall is a new subdivision by Lennar Homes, in Summerville, SC. Each of the homesites will be slightly different. While a picture is worth a thousand words, there's really nothing like seeing the homesite first-hand, and walking through the design center with your Realtor(R) to select the finishes you want.
Regarding the property taxes, that is going to vary according to what the final cost of the home is, whether or not it is your primary residence, and whether or not you are eligible for the homestead exemption for homeowners age 65 or older. Assuming that the final cost of the home is about $300,000, and it is your primary residence, the taxes will be about $1600 per year.
I'll be glad to answer any other questions you may have about this home, or help you search for another home in the Summerville area.
