There is no such limit on the number of times you can go for home refinance loans. Most lenders prefer that you have no late payment for the past 12 months before you switch over to a new loan.
Give yourself plenty of time to close. With most refinancings, your file is turned over to a closing or title company, which dictates the closing details. Like the lenders themselves, these firms are swamped when interest rates are low. Moreover, appraisers get backed up and can be difficult to schedule. So don't expect the closing to happen as quickly as anyone promises.
Ask for the reissue rate on your title work. If you've taken a mortgage within the past two years, or are using the same lender, you might be granted this option, which can save you as much as 70 percent on your title work. An editor at this magazine didn't know about this potential savings when he refinanced his mortgage; fortunately his lawyer did. The savings more than covered the attorney's fees. However, if it's been several years since you took out a home loan, or if you're using a new lender, you'll likely have to pay for a new title.
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.
