Interest rate and monthly payments for mortgage in Texas

Hello,

My fiancé and I have had our house for over a year and the house was sold for 246k. The outstanding principal is 194,670.13 with a monthly payment of $2,276.85. The interest rate is 7.5000%!

We clearly want to refinance as soon as possible, what interest rate would we need to obtain for the refinance, do you worth it in the long run and are they currently available?
