What is the incentive for a bank to refinance a mortgage at a lower rate?
What are you missing? Volume. Bank of America is more than willing to refinance a loan from Wells Fargo as long as the loan is still profitable. There are some caveats with that, though. For one, many land have penalties if they are paid off within two or three years. Additionally, the fact that banks are offering to refinance at great rates doesn't mean that you'll be approved, or that you'll get those rates. If you could post some actual numbers, we could help you see if it's a good deal to refi, and explain exactly where the bank expects it's profit.
