How It All Started

Working towards Kyle Olson’s Longest Open House began in Fargo, ND, as one agent’s tribute to his father — a powerful reminder that “home” isn’t just a place, it’s where our memories live. What started as a local event has grown into a nationwide movement, catching the attention of the National Association of REALTORS® and inspiring agents across the country to turn their listings into something more: a force for good.

Starting in 2021 the movement is inviting REALTORS® everywhere to take part. By hosting your own Longest Day Open House, you’re not just marketing a home — you’re making a statement, raising awareness, and helping fund the fight to end Alzheimer’s.

The Longest Open House started when Kyle Olson of Fargo ND wanted to find a way to fight Alzheimer’s through Real Estate. His first open house in 2021 was 61 hours of him staring at a wall and has now developed into a multi-state beacon of hope for those fighting with Dementia.  

NO, this is not a let’s see if we can Kill Kyle, but I intend to be at the home all weekend and available for any visitors during the entire time. Feel free to stop in at 3am and see if I am awake! (Bring some coffee). Last Year Kyle stayed up and was LIVE on facebook once every hour through out the event. Watch for the early morning streams for some fun videos!

The Longest Open House in 2024 raised just under $25,000 to fight Alzheimer’s. Kyle Olson set a fourth world record for the Longest Open house at 64 hours.
