The "pay the bond off" or not decision is mostly a personal one, kinda like whether or not to have a mortgage (if that is a viable scenario for the homeowner). A financial case can be made to paying the bond off but as has been stated by some, the tendency is for many people to just overlook the amount of the bond associated with buying a home in TV. So that adds to the complexity of what to do.
Bottom line to us has been to do whatever makes us sleep better at night!
