If you do not plan on staying in the house very long, refinancing may not be in your best interests.
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.
Close inactive credit card accounts to improve your credit score, making you eligible for lower interest rate loans. You will need to notify the credit card companies in writing that you wish the accounts closed on your request. Next, check your credit report after 30 days to be sure closed accounts include the comment "Closed at Customer's Request." You want future lenders to know it was your request and not bad credit that closed your accounts. Also, take the time to check for any mistakes in your credit report that could negatively impact your credit score.
Be Proactive. Your loan representative should keep in contact with you even if there isn't any action on your loan. But do your part to keep the lines of communication open as well. If you don't hear from your loan representative for a few days, pick up the phone and ask for an update. The old adage that the squeaky wheel gets the grease definitely applies in this situation.
