I knew numerous people that have a vacation home in Florida due to their parents retiring there and then passing away. They decide to hold onto the house/condo as an investment rather than using it in any way. Given how many people were retiring to Florida, I wonder how many vacation homes there are due to this rather than being the preferred purchasing location for younger generations.
