Not sure if this is the right place to ask.
There's this abandoned residential property (house) that's been empty/derelict for as long as I've known it (20 years) so perhaps for much longer. A mate and I have been chewing over going halves in land+building for a while and this property has always been on the back of my mind.
It's in an expensive area so it could be entirely a pipe dream alas I'm keen to at least sus out the asking price. Checked high and low and can't find the property listed anywhere, nor any historical records of transfer for that matter.
The house seems to belong to an elderly couple judging by a metric tonne of old photos (1990s), so they could have passed away by now for all I know.
What route can I go down to get an asking price, or what's the process for something like this?
