We're not crying, you're crying! It's the final season of Fixer Upper, and although Chip and Joanna Gaines are known for telling heartwarming stories, the Copp family's episode may have just slid into the top spot. The HGTV couple teamed up with former football quarterback Tim Tebow to transform a run-down Waco, TX house into an Americans With Disabilities Act-compliant home for Melissa and Jody Copp and their two sons, Calan, 9, and Lawson, 5 — who both use wheelchairs.

Shortly before their episode aired, Chip took to Instagram to let the show's fans know he and Joanna had set up a fundraiser with the specific goal of paying off the Copps’ mortgage. Shortly after the episode aired, Chip announced that the fundraiser was a big success: The Copp family is now mortgage-free!

"Y'all.. we did it!" Chip wrote in an Instagram post on Feb. 2. "The Copp family's mortgage has been paid in full. Thanks for teaming up with us to get this thing finished! Their lives are forever changed because of your generosity."

The family reached out to the show through the Gaines' charity, Magnolia Foundation — who then partnered with Tim's charity — because making the entire house wheelchair-accessible required more money and expertise than the Copps had. According to Joanna, the boys' condition is an "extremely rare genetic condition that affects the mitochondria in the body." In addition to being life-threatening, it "hinders their ability to stand and walk on their own, causing them to rely on wheelchairs for their mobility."

When Jody and Melissa got word the fundraiser met its goal, the two were overcome with emotion. Jody explained to Waco's KWTX, "We’re so excited [and] at the same time, we’re just still trying to breathe it all in. As far as the house, just being able to move in and what it’s provided the boys, the accessibility, it's just been amazing."

Melissa even coined a new word for their experience: "Dreality," or the sensation of trying to pinch yourself awake only to realize you aren't dreaming. "Don’t ever give up on your dreams," she wrote on Facebook. "So grateful for the prayers and support along this journey to get us to this amazing home that allows our boys to continue their adventurous life on wheels!!! We cannot say enough about Chip and Joanna and the Magnolia Homes crew, Tim Tebow, and all that support his amazing Tim Tebow Foundation, Make-A-Wish, and all that made this Wish possible. We keep rollin because of each and every one of you!"
