Congrats on paying off those loans! That's got to be a great feeling!
I know that a lot of people get gung-ho when paying off debt, which is great - but I think you should also be focused on building wealth as well. Before you decide to pay down your mortgage, be sure you have the following:
A healthy retirement fund
6-12 months of living expenses in reserve
Have adequate life, disability insurance
Still, after that, I'd investigage other options that will payout at a higher interest rate than paying down your mortgage. I agree that there is something psychologically appealing about owning your own home outright, but you can also get that same sense of security by building up a healthy investment portfolio, which could boost your net worth even more in the long run. Here is a link to where I discussed this yesterday:
Dave Ramsey on paying off mortgage...
For example, would you rather own a $200,000 home outright or have $250,000 in investments? This could be a typical scenario assuming you have a low-interest mortgage and invest in funds that yield a few percentage points more. If you choose the latter option, you can always decide to liquidate and pay off your house if you choose to do so - plus have extra left over as well. I think the second option definitely leaves you with more options, flexibility, and cash.
But that's just my $.02. In the end, each person has to choose whatever option he or she feels most comfortable with. I would just encourage you to carefully consider the math of each option before embarking on paying off your mortgage too soon.
