Here are some reasons why it is important for a home buyer to be approved for a mortgage before they buy:

 - Determine your budget: Getting preapproved for a mortgage gives you an idea of how much money you can borrow, targeting your search for a home.

- Save time: Preapproval can save you time by narrowing down your search for homes that are within your budget .

 - Save money: Preapproval can also save you money by helping you avoid homes that are out of your price range .

 - Determine obstacles: Preapproval also determines obstacles like excessive debt or poor credit scores.  When you apply for a mortgage pre-approval, the lender will review your credit score and credit history to determine if you are eligible for a loan .  If you have excessive debt or poor credit scores, it can be an obstacle to getting pre-approved for a mortgage.

 - Make an offer with confidence: A mortgage pre-approval allows you to make an offer with confidence and shows that you’re a serious buyer with the means to purchase a seller’s home .

 - Tour homes with confidence: Many real estate agents won’t even allow homebuyers to tour their listing if the buyers don’t show up with a pre-approval letter from a reputable mortgage lender .
