House is now 14% paid for

Somara picked up the mail for me to get to our meeting with the new potential D&D player. The great news was my overdue Seagate rebate for $50 but the other one was a milestone on our house. 
 
We are at the 14% paid in full mark on the mortgage. Another six percentage points and we can still Wells Fargo to go screw themselves on the escrow they manage to raise every year. 
 
I know this is trivial to many of you, but this is my first house. I want to see if I can get closer to the very-little-interest point.
