Refinancing my STRs at 2.5% 30 year fixed!

[Collin Hays]

So I have mortgages on all of my properties, 30 year fixed with interest rates in the mid 5s. A credit union here is offering to refinance them for as low as 2.5%.  That saves me $1000 a month from now on, and I think at that rate I'll just go 30 years.  Why would I be in any rush to pay off a loan at 2.5%?   

I am in disbelief right now.
