I think typically, you must put down 10 percent on the total pre-reduction price in order to get financing. In other words, the 10 percent downpayment is based on the total cost of $112 per point, without regard to the actual price you pay per point. Accordingly, if you purchased 100 points at $93 per point, your total purchase price would be $9300, but your downpayment would be $1120 (not $930). This makes a bit of a difference in financing.
To finance $8180 on a 10 year loan with the "preferred" rate of 10.75 percent, your payments would be $111.53.
