methodology →St. John has averaged 7.3% annual appreciation over five years and the trend is still live (+3.3% in the last 12 months). When a momentum trade keeps working, the simplest explanation is usually correct: more people want in.
St. John's population is shrinking 0.6% per year. Housing demand has to come from somewhere — if people are leaving, the buyer pool is shrinking faster than the inventory. That eventually shows up in price.
