When you move house there's always a bit of toing and froing over what's going to be left behind. But while you may spend hours drawing up delicate agreements and arguing over whether the garden shed is really worth £500, a study has revealed that we overlook other things entirely. So when you move in, you could be for quite a shock.
In some cases, the movers leave a gift for the new occupants. The study, by London removals firm Kiwi Movers, found that seven out of ten people will leave a present - and that the most popular option by far is wine, followed by chocolates and flowers, meals for the first night, essentials and houseplants.
Those moving into a new home in Surrey are most likely to receive a gift, and those in Birmingham are least likely. And the average price of the gift is a very generous £22.
Some people don't stop at a gift. Some 60% leave useful takeaway menus and bus timetables, 51% leave paint, spare wallpaper or tools, and 48% do a deep clean of the property when they leave.
However, not all the surprises left by the mover are so pleasant. Some 23% left behind rubbish, 8% moved without bothering to clean at all, and one respondent even admitted to taking every single lightbulb with him.
Rightmove ran a competition for unusual moving stories in 2013, and heard from one woman who moved into a property to find that absolutely everything had been taken - including the doorbell.
The National Association of Estate Agents said items are often left behind too. Some of the most common are the contents of the loft, phone chargers, and pets - which are taken but return on their own.
Other things left behind are decidedly weird. The Kiwi Movers study said one woman in London had been replacing the tiles in the kitchen when she found a copy of the Paris Hilton sex tape had been hidden there by a former occupant.
A man in Glasgow found a pair of glasses in the freezer, and a London author found an antique dentist's chair - which he sold on eBay for £700. Another couple found £300 stuffed behind the bathroom radiator when cleaning their new house in Manchester.
The Rightmove competition unearthed the story of a woman who moved in, and spent a night listening to a terrifying scratching sound in her bedroom. The following day the previous occupants arrived to say that their daughter's hamster had escaped during the move, and was probably hiding in the bedroom.
Another woman rented a property without viewing it. The landlord said he wouldn't be storing anything there - just the things hanging on the walls. She arrived to discover 87 clocks.
Meanwhile, a study by TV Licencing in October listed unusual objects left behind, including an undertaker's trestle, a potty, and personalised egg cups.
