I found our about TOTV through the following RE/MAX website:
http://www.lylesellsfla.com/custom2.shtml
One of the other pages was The Villages FAQ's and one of the topic was a comparison of total home costs for financed and cash purchases on both new construction and pre-owned homes for a $200K home and a $250K home. Since we are still in the looking stage (buying is about 18 months away), I cannot speak to the accuracy of Lyle Grants data. On the $200K home, closing costs for a financed new home is $13,651 and pre-owned is $5,515 (excluding the bond). Buying a home for cash, the same closing costs on the same house are $9.661 and 1,275, respectively.
Hopefully, Villagers that have bought new and used either for cash or with a mortgage can validate these numbers.
