I just bought into BCV so let's see if I can get this right.
100 points * $75 per point = $7500 total purchase price
$7500 * .1 = $750 for a 10% downpayment
If you take the $5 per point incentive (where they apply $5 per point toward your downpayment) then $5 * 100 points = $500 that they'll put in for your downpayment.
So $750 (10% down) - $500 (that they put in for you via incentive) = $250 that you have to pay.
I hope this is clear.
