If you’re thinking about applying for a home mortgage later this spring, here’s some important news: Beginning June 1, your lender is likely to order a second full credit screening immediately before closing.

The last-minute credit report will be designed to find out whether you’ve obtained — or even shopped for — new debt between the date of your loan application and the closing.
