The brief answer is the Quechee (Quechee Lakes) community is heavily slanted towards a second home purchaser. There are no problems with flooding and the condos are insurable. The annual dues structure in the community along with the real estate market crash of a few years ago has created a lowering of housing values and a growing stock of inventory.
Depending on what a purchasers goals are (will they use the QLLA facilities or not) will determine if the development is a wise investment. If you want to talk more or tag me an email feel free. I have been selling real estate in the Upper Valley (VT/NH) and started in Quechee Lakes almost 30 years ago.
