About
GrinnMcKee Realty Group #SistersInBusiness
GrinnMckee Realty Group has helped clients buy and sell in Collin, Rockwall, Kaufman, Hunt, Van Zandt, Dallas, Denton, Johnson, Navarro and Tarrant counties. We are sisters, wives, mothers, hard workers, and love to serve our church and community. We love building new relationships while helping new friends find their next home.
We have lived in this area for over 60 years combined. AND we love what we do. As your listing agent, I will work to find exactly a qualified buyer in the shortest amount of time with the highest return possible for you. We will take over the marketing-print, social, the offer, the negotiations, all the paperwork, and of course moral support. Selling can sometimes be stressful and we want to help you have the best and most stress free experience possible. We both know, having your property on the market the LEAST amount of time is a goal, however, we want to follow your lead and hear what YOUR GOALS are! As you buyer's agent, we will SEEK to understand your wants, needs, and a legitimate timeline. We will negotiate on your behalf to get the best deal and will work behind the scenes to make the transaction as smooth as possible. You get TWO for the price of one and you will be treated like family!

GrinnMcKee Reviews
Every client relationship starts with listening. Here's what working with Heidi looks like, in their clients' own words.
Heidi worked so SO hard to find us the perfect house and we thought we knew better and came in with a few listings then finally we listened to her and she showed us the house we wound up buying. Then she worked it hard to get the deal done too. She absolutely knows the region and the area and my advice would be just straight up listen to her, she’s probably right about the house she’s showing you.
