I refinanced last year for a 0.125% better interest rate, and the bank paid me $1000 to do it. It was the easiest decision I ever made. Basically, there was $5000 in closing costs and the bank paid me $6000 in points. If I paid money I would have gotten a lower rate, but I already had a great rate.

Now, I'm refinancing again, but I'm paying some money. All in all, my net refinancing costs will be around $2000, but I have halved my interest rate almost, and will now be able to pay my home off about 10-15 years earlier (we just bought two years ago).

My broker said it was a standard $3K closing cost if at zero points, but I ended up taking some negative points as a credit towards closing costs.
