When it comes to real estate, most of us envision tidy suburban homes, sleek city apartments, or perhaps a cozy cottage in the countryside. But for the daring (or perhaps the slightly eccentric) property investors, the world of real estate has offered some truly bizarre, unexpected, and downright strange opportunities. From underwater hotels to castles turned Airbnb rentals, the property market is full of surprises—some so odd, they’re almost unbelievable. Follow on as we embark on a journey through the most eccentric property investments in history!
1. Underwater Hotels: Sleeping with the Fish
Imagine falling asleep to the gentle glow of marine life swimming outside your window—sounds like a dream, right? Well, underwater hotels are a real thing, and they’re as strange and wonderful as they sound. The Utter Inn in Sweden is one of the earliest examples—a floating house submerged just below the surface, giving guests a unique “sleep with the fishes” experience.
2. Castles Turned Airbnb Havens: Fairy Tale Stays for Modern Tourists
Who hasn’t dreamed of living like royalty? Some entrepreneurs have turned that dream into reality by transforming historic castles into luxury Airbnb rentals. Take Ballynahinch Castle in Ireland, for example—a 17th-century fortress now offering guests a chance to stay in a real castle, complete with turrets, ancient stone walls, and a ghost or two, according to local legend.
In Scotland, the Glamis Castle – historic home of the Queen Mother – has been converted into a boutique hotel and Airbnb, where visitors can indulge in medieval charm, complete with suits of armor and secret passageways.
Why invest? These properties attract a steady stream of tourists craving a one-of-a-kind experience. Plus, castles tend to appreciate over time, especially when they come with a spooky story or two. Just remember, maintaining a castle isn’t for the faint of heart—or wallet.
3. The House with a History (and a Haunted Past)
Speaking of spooky, some properties come with baggage—literally. The Amityville Horror House is perhaps the most famous haunted house in America, notorious for its gruesome history and supposed paranormal activity, which of course led to the best-selling book and movie franchise. Unfortunately, much to the thrill-seekers and ghost-hunters dismay, the house is a private residence and is not available as an AirBnB or for public tours.
Similarly, The Screaming House in New Orleans, known for its eerie wails and ghostly sightings, has attracted paranormal tourists and adventurous investors willing to cash in on its spooky reputation. Another private residence and not open to the public, several ghost tours have it as a stop, but to only view from the outside.
Why invest? Haunted properties sell—if you’re brave enough to handle the spooky stories and occasional ghostly visitor. They often command premium prices from thrill-seeking tourists or paranormal enthusiasts.
4. The House with a Very Funny History: The “Hobbit” House
Not all bizarre properties are dark or underwater—some are just plain quirky. And a prime example of this is the well known Hobbit House, just up the road from me in Matamata, New Zealand. Designed to look like a hobbit’s burrow from “The Lord of the Rings”, this eco-friendly home has become a popular Airbnb rental and tourist attraction.
In South Africa, there’s a house shaped like a giant shoe, aptly named the “Shoe House”. Reminiscent of the popular nursery rhyme about the lady who lived in a shoe, Ron Van Zyl built the Shoe House in 1990 for his wife. It is a three story building and now houses a museum to display Van Zyl’s other work, such as wood and rock carvings..
These whimsical homes attract media attention and curious visitors willing to pay a premium for a stay in something truly out of the ordinary.
Why invest? Quirky homes often go viral on social media, bringing in free publicity and high occupancy rates. Plus, their uniqueness provides a competitive edge in the property market.
5. Underground Bunkers and Doomsday Shelters
In an era of geopolitical tensions and climate anxieties, underground bunkers and survivalist properties have become surprisingly popular. These hidden fortresses, often built deep underground or into mountainsides, promise safety from everything from nuclear war to natural disasters.
In the US, Mount Weather is a government bunker, but private investors have also gotten in on the action, transforming old missile silos into luxury underground homes.
Why invest? While not everyone’s cup of tea, these properties appeal to those who value security above all else—and they can appreciate in value as fears of global instability rise.
Embrace the Unexpected in Property Investment
As you can see, the world of property investment isn’t just about buying and selling traditional homes. It’s a playground for the bold, the creative, and the downright eccentric. Whether you’re interested in underwater hotels, fairy-tale castles, haunted houses, or even private islands, there’s an opportunity out there for everyone willing to think outside the box.
What’s the lesson here? Diversify your portfolio and don’t shy away from the quirky. Sometimes, the strangest properties turn into the most lucrative investments—if you’re brave enough to take the plunge.
