1. Exploding smoke detector

This story of a smoke detector turned out to be more of a smoke-effector, shares Jeff Miller, co-founder of US-based AE Home Group.
The previous owners of the house had moved out only one day earlier, but had not turned off their electricity or the air conditioning, recalls Miller.
In fact, the air conditioning was set to high, which at first seemed like a good thing, because the day of their inspection happened to be the hottest and most humid day of the summer.
Then, they started to smell smoke.
“Rushing down to the basement we found that condensation caused the smoke detector to short out.”
In fact, the smoke detector was now on fire.
“Ironically, the smoke detector almost burned that house down,” says Miller.
2. Fifi's final resting place

Jamie Green, of US-based WIN Home Inspection, was making his way on all-fours through a crawl space of a 70-year-old house.
“Crawl spaces are generally pretty spooky because you never know what you’re going to find,” Green tells Reader’s Digest.
Green stumbled on something strange as his hand touched down on something both bony and furry.
Turns out, it was a stiff cat skeleton with fur still intact.
Unfortunately, the home sellers now had an answer for what had happened to their missing feline friend who they’d believed had “run off” years earlier.
3. Pet cemetery

An old and rather dilapidated property was being sold as part of the estate of the deceased homeowners. Kris Lippi, a realtor with US-based Get Listed Realty, had buyers lined up who were really excited, although they knew they were going to have to do a lot of work to get the house into decent shape, so it wasn’t surprising when they learned that the home inspection turned up “a bunch of patched holes in the concrete floor in the basement – probably about seven or eight of them,” Lippi recalls.
Since the inspector couldn’t figure out any explanation for them, he noted in the inspection documents, “inconclusive concern requiring further investigation.”
Seeing the notation on the inspection documents, the adult children of the deceased homeowners cleared up the mystery.
Turns out: it was a pet cemetery. Every pet the family ever had was now dead and gone and buried beneath the house.
The adult children didn’t think there was anything weird about this at all. In fact, they asked that the buyers agree to never disturb the home’s makeshift pet burial ground.
Needless to say, the buyers were totally creeped out and cancelled the contract.
