Minimum down payment is 10%, which can include the point incentive discount (currently at $6.25 a point). So for 160 points you'd need to put down an additional $664 to meet the 10% requirement (160 X $104 = $16,640 X 10% = $1,664 -- 160 X $6.25 = $1,000 -- $1,664 - 1,000 = $664)
Financing is currently 10.75% for preferred automatic deduction (FICO about 740+) and 14.XX% for regular automatic deduction. Each rate is increased by 1% if you choose to pay via check monthly.
