The 10% minimum down payment on jumbo loans program is becoming increasing popular and gives qualified homebuyers with limited down payment sources an opportunity to purchase higher end homes. The maximum loan size on the 10% minimum down payment on jumbo loans program is capped to a loan size of $750,000.
If your FICO credit score is a 580 or higher, the minimum down payment requirement is just 3.5 percent. If your score is lower, though, the minimum down payment increases to 10 percent of the purchase prices of the home, assuming all other qualifications are met.
