While I did pay one mortgage down by 60+%, I still plan on maintaining mortgages and will start the refinance process right after New Year. I agree that rates right now don't lend themselves to carrying mortgages, but I'm sure enough that in 5-10 years things will be different and the 2.5% mortgages will essentially be free money. Of course, if you read back through my history making financial prognostications you'll see that following my advice can lead to less than happy endings. But I feel pretty confident about this. YMMV.
