Not being able to buy land in the city because the price is unaffordable and buying it in the countryside, but suddenly the price is good many times over because the government wants to build something, it has something to do with luck.
It could be luck, but it could also be the investor's knowledge, strategy and vision. Real estate is like any other investment, it requires knowledge, experience and especially vision...not just relying on luck. Luck is just one of many factors and it exists in every field, every investment, not just real estate.
Sometimes when we see someone suddenly become rich because they bought real estate or invested in a random coin, we are quick to assume they got lucky. But that's not always true because we are not them, just because we don't see its potential doesn't mean they don't see it either. Each person's abilities and talents are not the same.
