Your calculations are nearly an apples to oranges comparison..You are comparing "best case" of always being able to rent for $10 to the "worst case" of financing a DVC at 14% for 10 years (ouch).
Even so, don't forget to include in the calculation the fact that after the loan is paid off, you now have a valuable asset to either liquidate or use on more vacations for only the MF costs.
With renting you will have nothing but memories, good ones no doubt, but they won't get you a financial return.
