For mortgage professionals "closing the deal" means sitting at the closing table of a real estate financial transaction.  My assumption is that your question is "how do you attract and 'keep' your potential clients?" Just as every transaction is different, so too are the people who utilize my services.  I hope my professionalism, experience, knowledge, communications skills, and most importantly, referrals from previously satisfied homeowners and realtors are sufficient to gain the necessary trust to utilize my services.
