Nor land.
Believe me, our land has not gone down in price since we bought the place. Its at least tripled in value in eight years.
We bought our house 9 years ago for $55k. It was assessed two years ago at half a million dollars.
Waterfront can also have higher insurance costs especially on the coast. If you can get insurance. Ask people in FLA.
The cost of flood insurance is directly proportional to how high your house is above the floodplain. My flood insurance is less than $200 annually because my home has a crawl space under it that you can stand up in. As far as homeowners insurance, there is always someone willing to sell you insurance. Believe me, from personal experience.
Lots of land is not hard to manage. If one has 10 acres you don't have to have 10 acres of lawn. Our house sits on 4.5 acres and we have the same amount of lawn as our old house in the city that sat on .2 acres.
Since none of my neighbors can see my house/lawn, if I decide I'm too busy to mow or have something more important to do, like go to WDW,

then the lawn don't get mowed. No biggy.
That is harder to do when your houses are all but touching each other and you should care how the neighborhood looks.
I live on an island, and it's not overly populated, and the neighbors aren't exactly close.
LAND!
