Exactly!
By putting all of my effort towards becoming debt free, I will have a paid off house and will be able to heavily invest towards retirement. I estimated the difference between that plan and doing the normal 15% retirement savings and normal monthly mortgage payment.
The final difference between the two is approximately $33K less in a retirement fund, but a savings of $75K in mortgage interest. I think that $33K buying security for me in my retirement years is well worth the investment.
