The value is similar but the mountain home is just 1250sf and our city home is 1850. And fortunately we bought it when we were just 42 and had the physical energy to do all that work. It's interesting the worry/fear part. We were for the first 5 years as well. We've grown comfortable with that. We do have 3 nearby neighbors who live their full time and keep "an eye out" and have our # if we need to get up there quickly which is sweet.
And I totally understand NOT wanting to own 2 homes. DH is a homebody. He will travel with me if I ask, but he'd be OK if we never went anywhere. So we have the cabin, and I do part of my traveling without him. I do some travel for work and for continued education so I tack on tourist days to those trips and get my travel fix
