From my rough calculations (20% off rack with 3% annual increase in hotel price), break-even point if we stay in the "cheap moderates" (Caribbean Beach/Coronado when it's just the 4 of us and Ft. Wilderness Cabins with 6) is like 18/20 years...I didn't get that far. But if I swap out Ft. Wilderness Cabins for a Jr. Suite at the Coronado, break-even is more like 10-12 years. Does that seem about right?
I'm not sure which dates you used exactly or how many points. I poked around a bit to try to find an available reservation for a Junior suite at Coronado. The only one I could find was a King suite October, which $3802 after taxes. For a 1 bedroom standard at AKV in October x 1 week would be 181 points.
So with the following assumptions:
1. AKV
2. 181 points per year (to cover a 1 bedroom standard villa at AKV in October for 1 week)
3. $85 per point purchase price
4. $645 closing costs
5. 3% increase in both rental rates and DVC MFs per year
6. $3802 - 20% = $3041 per year cash price Coronado Jr. Suite
Breakeven is year 8 (DVC $26,630 vs Hotel $27,042).
If you include lost interest at 4%, you get
Breakeven year 10: DVC $29,695 + lost interest $3688 = $33,383 vs Hotel $34,862)
Again, long term by the end of the contract, lost interest is above $92,000 IN FAVOR of DVC ownership, for the reasons I described previously.
This may or may not be exactly what you got. It depends on what dates you use, etc. But in general, the cost of a junior suite at Coronado Springs appears to cost more than renting DVC points for a 1 bedroom standard at AKV, so it should be shorter than whatever number you got when comparing DVC ownership to
DVC rental.
Edit to add:
If you buy a 200 point contract (since it's usually good to have a few extra points if you can) and keep the cash price the same, break even becomes year 10 without interest, year 12 including lost interest.
