When refinancing, don't take the first offer that comes around. Instead you should actively compare both interest rates and lenders.
Be Prepared. You'll probably be asked for more information and documentation after you submit your application, but before your loan is approved be prepared to document your income and assets. Answer any questions and fax documentation to your loan representative as soon as possible.
If you are making payments on a long term loan, say, 30 year mortgage for the past 10 to 20 years, then refinancing to another 30 year loan will not be a good option as it may increase your overall payment.
When lenders offer a "no-cost" loan, they may include a prepayment penalty to discourage you from refinancing within the first few years of the loan. Ask the lender offering a no-cost loan to explain all the fees and penalties before you agree to these terms.
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.
