You gave new bank $15000
Your new bank gives you $2000. Your old escrow is $10,000,
assuming "我的新旧贷款的escrow 基本不变." the refi cost is 15000-10000-2000 = 3000.
montly payment reduced by $30, so that takes 100 month to break even.
100 months = 8 years+
Who the FXCK are you doing this for !?? Are you a retard? are you wasting my time so that you can BREAK EVEN in 8 years? Who the fuXk is making money in this deal?
The frigging loan agent!
Sorry for my language, but you are the not that bright.
