Possible that the property owner died with no relatives, friends or heirs. No one missed him. (No neighbors?)
If so, who has been paying the property tax all these years?
Someone had to own it for these guys to be able to buy it all.
What about the Grand National in the driveway?
What's in the red trailer behind it?
What else is there to find under all the crap in the house?
Some intense Google sleuthing, and then a country records check, might turn up the property owner's name. Not that it matters, except to try and trace the owner history of the car.
