Wow! Dirt is worth more in many real estate sales than structures.
Dirt is a good way to look at it. Back when we were tourists, we looked at a number of houses, just to get an idea of costs, locations, etc. One of our earliest houses, we read something about 6000 SF for only (I forget - but sounded really cheap.) When we got there, it was a beautiful house, great view, BUT no way was it 6000 SF. The realtor said, no, no, no, that's the land. Sure enough, around the house was a strip of grass abut 3 feet wide plus a side walk. The house and just a bit of landscaping pretty much took up the 6000 SF of land.
Yeah, we had some friends (he was a specialist doctor of some kind.) He lived in Portlock which is a ritzy suburb of Honolulu. They had a very nice house with all the trimmings (pool, panels, granite counters, all stainless appliances, etc.) While we were sitting on the lanai, he pointed to a house across the street. He said "That just sold for 1.1 mil. It's a tear down." (This was 12 years ago, so 1.1 was still a chunk of change for a tear down.) I looked at the house and I couldn't see any flaws. Good roof, nice windows, well maintained, etc. SO, it was just that someone wanted that prime spot for a really nice house.
I never saw the final result as the doc and wife gave up on Hawaii and moved to (IIRC) Hilton Head.
It's nice to have enough money to buy a tear down, but I'm just fine with still loving our condo.
