Can you give brief run down on a couple of things?
What interest rate are you being quoted?
What is your credit score?
What is your current balance and what are you trying do; cash out or rate and term refi?
What is the estimated value of your home?
What type of mortgage do you have right now, FHA, VA, USDA or conventional?
Without knowing a few things, it's impossible to determine if you're getting a great deal.
