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.
Many people with poor credit history look to take out loans from friends and family. While this may be a fairly good short term solution, it might not be the smartest of long term business moves. What you need to do is refinance your mortgage and lower your payment. The best thing you can do for yourself is to shop around. I'd be willing to bet that some banks will give you a better deal on a mortgage refinancing than you think they would. Find out who's got the best rate to get the best deal on your loan. This might take a little legwork, but it could pay off. Finding that right bank to give you the right deal on your refinancing will be worth the effort.
Weigh the costs carefully of how long you will be staying in your home vs. how much of a savings you will be getting in a refinance. Make sure you include closing costs in your decision.
If you have bad credit, find a lender who is willing to work with you and offer you reasonable loan terms.
