It's probably a personal choice between two things:
1. Not being able to save a lump sum for purchase and/ or not willing to forgoe the usuage until savings can be made
2. Not wanting to pay more.
I would say if you absolutely cannot or do not want to wait for whatever reason....then go ahead and finance
If you are an existing member, or not completely dedicated to the
DVC idea.....i would wait and attempt to purchase cash
You do pay more on the financing....that's a pretty common basic economic fact that tends to be pushed aside with "it doesn't cost that much more" kinda comments...
It doesn't matter how much more it costs....the fact is you are paying more for the same product. There's no way to interpret this any other way....if you finance....you are paying a higher price for the points. And over the whole life of the contract....including current, upcoming, and past vacations....
With something a timeshare.....which is in no way anything close to a necessity....it is prudent to make every attempt to not take out a loan or finance....
just my opinion
