The mum-of two who has been battling invasive cervical cancer, tweeted the picture of daughters Zoe (12) and Hayley (7) celebrating the move earlier today.
She also pointed out the poignancy of the date as she explained that the occasion also marked the anniversary of her mum's death.
“Not only was yesterday eight years since my mum passed away, but it is the day that we closed the deal and got the keys to our new home,” she tweeted.
“The girls are just (a) little bit excited…no matter what the future, this is a golden memory for them.”
The 32-year-old, who was diagnosed with invasive cervical cancer four years ago, recently returned home from Mexico, where she received four weeks of intensive treatment.
The Co Longford woman, who had been given the drug Pembro in a bid to prolong her life, revealed that results from a recent scan indicated that her cancer was stable.
“I have good news,” she said in a video on Instagram.
“My cancer is still stable which is just absolutely amazing to think that it's still under control. I’m so grateful.”
She also thanked those who had wished her luck before the treatment got underway.
“It’s AMAZING how much healthier I feel months on,” she wrote. “I am so grateful to still be alive and feeling the way that I do.”
Speaking on RTÉ’s Late Late Show before she headed off to Mexico, Ms Bennett had said: “I’m trying to have backup plans for treatment to try and stay alive. I’m trying to go way into finding everything.
"I plan to try and stay here for as long as I can, absolutely. I’m not delusional but I’m hopeful.”
Her trip to Mexico for treatment became a reality after a major fundraising campaign received massive support nationwide.
On her return she revealed her amazement at how much better she was feeling recently and shared a clip from an interview she did at a time when she was struggling to accept her prognosis.
Speaking with the What's Your Why podcast before she travelled abroad, an emotional Bennet shared that had made peace with dying but could not make peace with leaving her daughters.
“I’ve made peace with the fact that I’m going to have to die. I haven’t made complete peace with the fact I’m going to have to die soon,” she said.
“I can’t make peace with the fact that I’ll have to leave the girls. It’s something I just can’t do.”
She added: “I’m sure all mammies want to support everyone until the end, but knowing that you more than likely don’t have the chance to get to an older age, it’s really really tough.
“It's something that doesn’t sit with me at all.”
