Refinancing

Interest rates are crazy low so I'm thinking about refinancing.  Unfortunately, my loan-to-value is pretty high so I don't have much equity.  I don't think closing costs would be more than the equity I do have and I have an FHA loan which has a streamlined refinancing option.  I think I might be able to save roughly $200 a month which isn't anything to sneeze at given I live paycheck to paycheck.
