If the credit is stellar.....
$417K in first lien position(conforming loan and conforming rates) and the rest in second lien position(a little higher rate). The "blended rate" will likely be better that a jumbo loan rate.
Everyone is different..... And this is for to notch credit....
But on deals like this.... You really need to apply and let your loan officer run the numbers and see if you can get the second lien.
