When you do a cash-out refinance you are leveraging the equity in your home in order to receive a lump sum of cash at closing. Many individuals and families use this type of loan if they want to remodel their home, or they have kids that are attending college soon. Veterans and other military personnel can now take advantage of a 100% cashout refinance thanks to the Veterans Benefits Improvement Act of 2008.
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.
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.
Pull your credit report from the bureaus and review it for any negative items (late pays, collections etc) and inaccurate detail. Try to dispute negative items and remove them from the report. If required pay off any unpaid debt. Otherwise, you won't get a low rate and may not even qualify. Of course there are lenders in the subprime market who may offer you a bad credit refinance loan, but it's better to avoid them as they'll possible charge higher rates and fees.
