On the dues question, don't underestimate that expense... It's generally over 3x what your initial investment is over the life of the contract, perhaps more. Those little dollar differences add up.
Dues are important, and significant, but in a resale case between BLT and AKV, less so. BLT is going(asking) in the low 120s, AKV in the low 90s. Almost 30$ less per point. Difference in Dues is about 1.20 (BLT being cheaper). Dropping the difference down to 24 per point, it would take 20 years for the additional AKV dues to eat up the savings of buying AKV.
(This assumes no ROI on the savings, not Time value of money adjustments, assuming the difference in dues stays the same etc - it is just a basic raw calculation)
So, while dues are important, and do indeed add up, (and can be 2-3X the actual purchase price over the life of a contract; certainly nothing to sneeze at) they are somewhat negated by the large difference in price per point in this particular case. But still, they are something for the OP to consider. (If you were to change AKV to BCV, then dues are MUCH more significant due to the higher price per point of BCV)
From a strictly numbers/real estate view, I do think BLT is a better value.
As a PP pointed out, the difference in the 2 costs over life is about 16K.
things to note are
1. that assumes same contract size; AKV is cheaper point wise.
2. the calculations include no ROI on the money saved today
3. The 16K more that AVK costs over the life of the contract is not an expense that is incurred for about another 20 years; so that is 16K 20 year from now - and spread out over the remaining years.
Based on the above (and including an ROI on the initial savings, and TVM) I think total Cost Of Ownership will be virtually equal. Again in this case due to the large price per point difference. Financially speaking, BLT would blow away something like BCV as the better buy.
