Why is land in Hawaii so expensive

If you were offered the B&B on Kauai and you want to know what the B&B generates in the year, then sit down with the current owner and look at his books, if he wants to sell, he has to reveal his cards. Sure, the island is not that overcrowded, but you need guests and it is not exactly easy to get to the island, most of the planes, I think, fly to Honolulu and the Big Island, also internationally.
And if a few wealthy people have settled there, that certainly has no effect on your business.
You have to think realistically, first of all what the B&B costs, plus any taxes, then you have to include a start-up phase, various purchases, and then I would research the reason for you, why does he want to sell it? You should also go to the County Office to see if there are any restrictions or are planned. Perhaps gas should be drilled nearby or an airfield should be built, etc. You can also find out everything on the Internet, you just have to have the address of the B&B or the cell number and the name of the business, then you can in the public record look, everything you want to know, such as the property tax etc. Also look at www.zillow.com there is also the value of the property and the building, but you have to have the exact address, then you can see how it was once bought and whether there are mortgages on it. None of this is a secret in the USA, but anyone can look it up. So I can research in our subdivision what my neighbors have paid for their house, how much tax they pay, etc.
Good places on such a beautiful island are not sold without a reason.
You ask how expensive it really is in Hawaii? Very expensive. So we were often in Hawaii, mostly on Oahu and the Big Island, also looked at real estate and lived in an apartment and did all the shopping on site. In Oahu there is a WalMart and other large stores, but Big Island didn't have this selection, we only found smaller shopping centers, although the island is a lot bigger. But it is also due to the fact that Pearl Harbor is a large Navy base and many Japanese come to Oahu, who then also spend their money heavily in the "luxury mile" in Waikiki. And Pearl Harbor is also a tourist destination because of its sad past.
You write that the real estate is not expensive in Hawaii, then you have to take a closer look at the houses. Hawaii is very humid, and most of the Haeser we looked at were not of the best quality and much more expensive compared to normal states on the mainland. When the houses are still under the greenery, Mildew strikes quite nicely. Many of the houses are built with island wood because the building material has to come from the mainland. So you build with wood, which is also practical, you hardly ever need heating. But due to the high humidity, air conditioning must be provided, otherwise you will get into damp beds in the evening. In the north of the Big Island there is also, when the Pacific has high waves, the salty air comes far into the island, so also into the house. Then it is nice to have the sea so close, but the salt is everywhere. That's why we saw a lot of houses that were very simple, sometimes it was thought that people only use them as holiday homes.
Then Hawaii has another problem, the many homeless people who have somehow got to the island but have run out of money to leave. During our last stay they tried to get the homeless off the islands with paid tickets, but it only partially worked. Entire homeless cities have established themselves, mostly on beautiful beaches.
If you have the necessary change and absolutely want to live on a Pacific island and don't want to run through the mill of US immigration, there are other options in the South Pacific, such as Fiji etc., which also have immigration regulations, but not as strict as they are the USA, but no matter how beautiful an island is, it remains what it is - an island.

In this sense. Greetings. Albacor
