But a property expert has warned that the classic new home announcements can be dangerous, as it puts yourself and the property at risk.
In a TikTok video that has racked up over 1 million views, Kyle Mattison who is known as 'That Property Guy', advised new home owners to be mindful before clicking that 'post' button as there are computer programmes that allow you to recreate the keys simply with a photo.
The 29-year-old said: "Normally, people who buy their first homes would put a close-up picture of their keys and share the news on social media.
"What they don't know is that this needs to keep under wraps. It's possible that people can take the picture and use a computer programme to replicate the keys.
"It's not common, but it can happen. I've seen a lot of people recently getting their keys to their new homes so I thought I'd help them to stop doing it, really."
Kyle, who is based in Portsmouth said although sharing the exciting news can be seen as harmless, people tend to overlook the fact that such information is considered private.
"People who left their comments on my video said if people want to get to their house, they are going to do it anyway.
"But there's a level that you sort of toe the line somewhere and the key is probably part of the line,” he said.
