There isn't a right or wrong.
If you absolutely think that there is no way you will EVER, EVER, move again in the forseeable future, pay it off.
But if you think you might want a bigger house, a smaller house, and especially a bigger garage.
don't.
AND houses are easy to sell here IF
They are well presented.
Priced right,
Belong to non smokers.
and are perfectly clean.
They are much easier to sell here than anywhere else in this country.
So easy that many people sell them without a realtor.
BUT...if you are a bloom where you are planted person.......THEN
Pay off the bond.
Especially if you are a "youngun".
