Your mortgage company will begin the work of verifying all the information you've provided. This process can take anywhere from one to four weeks, depending on the type of mortgage you choose, whether you're buying a home outside your local community, or a host of other factors.

Within three business days after your application, the mortgage company must give you a good faith estimate of your closing costs. You'll also get a statement that shows your estimated monthly payment, the cost of your finance charges, and other facts about your mortgage.

Stay in touch with your mortgage company to speed up the application process. Some home buyers find the closing process to be one of the most intimidating aspects of buying a home because it's so unfamiliar. If so, ask your mortgage company what to expect at your closing.

Once you receive your approval, and you're waiting to close on the purchase of the home or the refinance of your existing mortgage, don't go on a shopping spree. The mortgage lender may do a final check of your credit report or bank accounts to make sure you're not assuming more debt or spending your cash reserves. There are steps you can take to move quickly if your loan is denied.
