OP said "higher interest rates" relative to historic lows in '20-21.
Your comment does not negate the effect that interest rates have had on affordability. The last time interest rates were this high, home prices were significantly lower than what they are now. Wages have not kept up with inflation.
>SQLite4 was an experimental rewrite of SQLite that was active from 2012 through 2014. All development work on SQLite4 has ended. Lessons learned from SQLite4 have been folded into the main SQLite3 product. SQLite4 was never released. There are no plans to revive it. You should be using SQLite3.
