The present that I think people have appreciated the most when they move into a new house or a new condo they have just purchased is a basket of food, a really nice lunch that comes to the door of their new home, the day of the move. People who buy a house and have to move are so exhausted that day, the stress is so great, that any attention they get will not be forgotten. They will remember how that pizza or this basket arrived at their door with their real estate agent card in it. "Bienvenu dans votre nouvelle maison" Or " Bienvenu dans votre nouvel appartement de la part de votre agent Immobilier". Remember that memory works at its best in time of stress and the day of the move is certainly stressful. Therefore, you , as an agent , get the best chance to be remembered. And you have done your good deed for the day!
