Underwater for me is selling and having to bring money to the table. So, depending on length of loan will determine that so as long as someone holds restricted resorts as long as they have the loan they won’t be underwater.
Assuming people do the 10 year
DVC usually does, but that point, owners can sell.
Now, if you are talking underwater in the sense that they don’t get all the purchase price back? Yes, that is very possible
But it’s why I don’t think anyone should buy DVC, financed or not, assuming a resale value other than 0.
If one does that and figures out at what point it still makes sense against the cash stays one would replaced then what you can sell for down the road is a bonus.
When we bought in 2009 at BLT, we knew at 10 years in, we could sell for $0 and still come out ahead against our yearly trips. We figured we wanted to be in it longer than that so it was a good deal.
Of course, we have since added on, go more often, etc so there is no savings any more..but when or if we ever sell, whatever comes back is more than we expect. Which is $0.
