The map they sell at the Mercantile shows the county lines and which villages are in which county. You can get on by mail but someone else will have to tell you how. As to taxes:
2007 Millage rates were:
a. Villages in Lake County: 16.9329 per assessed thousand plus $371 for fire and solid waste.
b. Villages in Sumpter County: 13.5843 per assessed thousand plus $61 for fire. Solid waste is billed separately on the utilities bill.

Note that all villages in Lake Co. are also within the city of Lady Lake and the city has their own tax assessment. One can weigh these slightly higher property taxes in Lake County against having no bond. It is hard to make a general statement about which county is more tax favorable because the price of the home, whether it is your primary residence, and any assessments or fees imposed by the CDD affect the overall cost of home ownership. If you are on a fixed income, you will have to calculate each home separately in order to avoid surprises. The people in the county tax offices seem very helpful and willing to assist.
