Does that mean you think my loan proposition is fair, or is not fair? If you think it is fair, then by all means use your analysis to make your decision. If you think it isn't fair, then at least hear me out.
To be honest, the most helpful thing to do would be to edit the work that I've done and share it, but I realize that sometimes it's just easier to talk about it rather than fix it.
That's reasonable. Another poster already gave what I think is the easiest approach to correct the error: just use the current dues figure, multiplied by N years, rather than increase them by inflation. That way, you treat both the purchase price and the dues in present-value dollars.
Using this technique with your assumptions, the resorts from most to least expensive, are:
VBR: $16,613 + $1,520 * 35 = $69,813
AKV: $25,631 + $1,247 * 35 = $69,276
BWV: $22,372 + $1,310 * 35 = $68,222
BCV: $24,065 + $1,250 * 35 = $67,815
VWL: $22,343 + $1,277 * 35 = $67,038
HHI: $18,784 + $1,345 * 35 = $65,859
OKW: $20,210 + $1,188 * 35 = $61,790
SSR: $21,676 + $1,112 * 35 = $60,596
That's a different order than you come up with, which was:
VBR, AKV, BWV, HHI, BCV, VWL, OKW, SSR
Now, you could argue that dues might increase faster (or slower) than inflation, and so dues should play a larger (or smaller) role in the total cost of ownership. And, I'd be fine with that. You could also argue that you might expect a higher (or lower) rate of return if you'd used the purchase price for something else. Again, I'm okay with that. But if you treat the purchase price only in present-year dollars, and the dues in then-current dollars, you are making a mistake.
