Should I try to refi 10 yr int only arm on a rental house with rate now of 7.25%? - what libor rate is my arm tied to

I do not want to waste time, unless you think I can save money on my monthly payments. I make $ 130K per year, with 60K of unsecured debt and a credit score of 700 Would it be advisable to observe a refi?
I looked into this for my living room, which has an arm Libor to 5.15% and not find a place to save $ too.
