There is a refinancing myth that says you should not refinance your mortgage unless your interest rate will be at least two points less. This myth is not necessarily true if there are other benefits to the refinance or other reasons behind it.
If you have bad credit, find a lender who is willing to work with you and offer you reasonable loan terms.
You can also save money on your mortgage refinancing by paying "points." This is a fee that effectively lowers the interest rate of your loan. If you plan on staying in your home for a long time, this long-term strategy can be an excellent way to save thousands of dollars.
When refinancing, don't take the first offer that comes around. Instead you should actively compare both interest rates and lenders.
