I found that one of the best things I did for an escrow officer was send her a hand written thankyou card and emailed her Manager thanking her for the great service she provided. The only draw back was, she was up for a promotion and that helped seal the deal so now I rarely get to talk to her.
I've also worked with her manager to help coordinate for me to deliver a pizza party for the entire team (about 10 people) to recognize the officer and the service she and the team provide. I relized the other team members had to cover her, so she could keep my deals together.
By the time of the pizza party I had 2 bankers wanting to help pay for it, my brokerage wanting a piece of the action, and the Company wanting to help pay for it. It turned into a impromptu Title Company appeciation party for the employees. I got to speak and recognize her, and present her with a cheap framed award, and we had a small party in the office.
All told I was out of pocket 25 bucks, that provided pizza, pop, beer, wine and a lot of entertainment in the office. Title Co's are used to entertaining Realtors and loan officers, when the role is reversed, they love it!
