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.
It is feasible to go for a refinance when you have built up at least 10% equity in your home (For Fannie Mae owned mortgages, the value is 5%). It is also possible for you to choose the option if your equity is less than 5%, but you may have to pay a certain amount of cash in order to make up for the difference in equity.
If you are planning to stay in your home for several years, then you can save money by paying points for lower interest rates. You pay up front fees to ensure you have lower interest payments over the course of your loan. Remember, this only works if you keep your mortgage for several months.
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.
