Being Pre-qualified and why
Sellers have a very different view of a Real Estate transaction then do Buyers. A seller wants to know that the potential buyer walking through his or her home is, at the least, capable of getting financing to purchase his home. 

A buyer in most cases can get pre-approved over the phone in just minutes. Most lenders will send a letter to the buyer stating that he or she has been pre-approved. This letter submitted with the offer can make the difference of having an offer accepted or not accepted. 

Getting pre-approved by a lender starts with gathering information such as income and long term debts. With that information, the lender can estimate the maximum house price a buyer should be considering. It is important that a buyer know how much they can afford in order to look at homes in the correct price range.
