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.
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.
Be Inquisitive. It's your responsibility to make sure that you understand the terms of your loan. Ask questions and listen carefully to the answers. Don't sign your loan documents until you are satisfied with the information and confident that you have made the right decision.
