Make sure you have a personal touch after closing. Call your client, meet them at closing, or grab a cup of coffee to congratulate them in person. While gift-giving is very important, make sure to take the opportunity to write them a letter or give mail them a card. Somethings like:Dear (client), Congratulations on the purchase of your new home. I am blessed to have had the opportunity to work together and build a lasting relationship through this transaction. Thank you for that opportunity. I wish the best for you and your family and look forward to continuing to build our relationship over the coming years.
