have you sold your current house? I'm not really understanding your situation. Will you be keeping both houses until your house sells? Is the new house that much more $$ because of the waterfront location?
I think you will be happy in the new house because you can't change location. Over the coming years you can redo the interior to make it more "you"- not every change has to be a catastrophic one that costs tons of $$. Little changes can make a big difference, as I'm sure you know. But if it will be your forever home, I would do it.
We moved from our custom-built 3500 sf house to a 3br/2ba 1500 sf apartment 2 years ago (overseas military move, we live on a base now). It has been great actually. So much more simple and I realize we don't need so much "stuff". We are getting ready to move back to the house this summer and I'm kind of dreading it!
