This is a lot of hassle and commitment when you only plan on visit every other year. DVC is a lot of money upfront and it’s not an easy system to use or plan.
There are lots of other options, like renting a week at Bonnet Creek on Redweek, that will be cheaper and get you a kitchen.
Right now, you can only borrow 50%, which makes attenuated planning like this even more difficult. As 2020 showed, they can change the rules under you and you can’t even pull of what you want to do. If I were visiting every other year, I would rent DVC points or another timeshare system.
The boardwalk 1BR is a sweet spot on the
point charts, and I would argue renting boardwalk points for a 1Br at 11 months is a better mathematical plan than buying either contract.
