The issue with financing for me, and why I think it's to be avoided where possible, is the impact of finance charges on the total cost of
DVC. People tend to look at financed DVC purchases in one of two (bad) ways:
1.They say "My DVC contract cost $15000," and never look at the additional money paid out in finance charges. A $15K loan, paid over 10 years, at 9%, is saddling you with around $8K in interest. So, if you finance the whole thing and take the full 10 years to pay it off, your DVC purchase cost you $23000, not $15000.
2. Nowadays, many sellers of financed products, from car dealers to timeshare salesman, present the deal as "X dollars per month". The buyer says "wow, I can afford that!" and never considers what they're really paying (see above).
At some point, the finance charges can drive the cost high enough that it's no longer the good value the buyer first thought it was.
