Ideal gifts for a realtor

My boyfriend and I are selling and buying through the same realtor. We have been working with her for about 4-5 months. We will be officially done with everything at the end of the year and she goes above and beyond her job title as far as lending us things to help clean and fix, and also goes above and beyond for nearly everything. She's really nice!

We were things flowers and a gift card for coffee, but what else should I add!?
