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.
You can ask for a copy of your settlement cost papers (the HUD-1 form) one day in advance of your loan closing. This will give you a chance to review the documents and verify the terms.
Homeowners who want to refinance but can't because they owe more on their home than their home is worth (also known as "upside down") should focus their time and energy on making more money. Adding a part-time job or starting a side business will bring extra income into the household, income that can be used to make extra payments a mortgage.
If you have bad credit, find a lender who is willing to work with you and offer you reasonable loan terms.
