If you know that you will be moving in 3 to 5 years, you might want to consider refinancing to a 3 or 5 year ARM (adjustable rate mortgage). These loans typically have a much lower rate that a traditional fixed rate loan such as a 30 year fixed, but they do have a fixed rate for the first 3 or 5 years of the loan. This will enable you to benefit from the lower rate, but you won't ever have to worry about the risk of a rate adjustment because you will be selling the home before the fixed-rate period ends.
Both new homebuyers and refinancers can get free access to the credit reports that lenders use by visiting AnnualCreditReport.com, a website created via Congressional mandate. A free report from each of the three consumer reporting agencies -- TransUnion, Experian and Equifax -- is available at no cost every 12 months. Check for errors; if mistakes are found, don't hesitate to dispute any and all inaccurate and derogatory items.
Know your credit score before you begin looking for a loan. If you can, try to remove any blemishes from your credit report before applying for a refinance.
If you have equity built up in your home, and you need cash, you have two choices: get a home equity loan or utilize cash-out refinancing. Each has its pros and cons, so be sure to evaluate your situation carefully prior to making a decision.
