I found this thread very informative, and can see that this is a very personal decision which takes a lot of individual factors into consideration.
At this point in my life, a vacation house is not under consideration. I am still working six/ seven days a week, and the time I get for vacation, I would like to use to visit my baby granddaughter. (That means more to me than anything else.)
When we retire, DH wants to spend time driving around the country.
So, after a bit of rest, a long overseas visit to my in laws, and one or more visits to baby granddaughter, we will be traveling around the country.) He has dreamed of this for a long time . . .
We anticipate moving to a lower cost of living area. Having to look for another full time home will take priority.
Our retirement budget is still up in the air (yes, I have been saving but our expenses will change) and I will have to get used to living without a paycheck.
Not sure I want the responsibility of a vacation home.
Now, after the dust settles, who knows, we could fall in love with a home down South and decide to snow bird. Never say never.
