Just like the cure for high prices is high prices and the cure for low prices is low prices, the way to ruin the best place to live is to tell everybody about it. Boise was rated #1 place to live in all those magazine articles of the 90's and early 2000's and the cows have come home to roost.
Prices of real estate have skyrocketed, I think Boise had the highest rate of real estate price increase in the nation. Wages have never kept pace with the cost of living, particularly real estate, and as I understand it folks are actually starting to leave because they can't afford to buy a house or rent an apartment here.
For a while very recently houses were being snapped up at asking price or even higher in 2-4 hours of listing it. My friend's mother-in-law died and they sold her house here 2 hours after listing it. Now I'm seeing nice houses sitting with for sale signs for days or weeks, quite possibly for the same reason lots of nice firearms remain unsold. Folks want and expect top top top dollar and when they see what other people are asking for "similar sales in the area" they just keep adding more to their asking price.
But out of state developers keep developing and the city and county commissars, uh, commissioners are totally in their pockets. 8-10 story apartment buildings are being approved in what were and still are single family residential neighborhoods. South of town the housing developments are going up as fast as they can bulldoze a piece of farmland and move the dozers to the next chunk of land.
The bright side is I'll be dead before it hits Portland, Seattle or Denver status. Maybe.
