So, just got off the phone with a lender. My options are:
A. I can get a 4.75 rate for $2,300. Savings of $60 a month. Break even is 38 months.
B. I can get a 4.00 rate for $2,300 switching to a 15 year from 30. Savings of $115 a month. Break even is 20 months. Actual increase in monthly payment is about $400, which I can handle with no problem.
C. Just go to Vegas.
