> Moving your family every 2-4 years sounds awful.
It's life for a lot of people.
Here in the UK, many renter families have no choice but to do that their whole life, with the added indignity that they don't decide when it's time to move, the landlord decides at short notice (either by unaffordable rent hikes or no-reason evictions (which are often for renovation rhen hikes too)).
Sometimes they don't know which area they will be moving to, when that happens, because they will be unable to stay in a familiar area as local rents rise collectively and what they can afford gets progressively worse, until one day they can't find anywhere local at all within the notice period.
So sometimes the children have to move schools as well at short notice.
I think stability is the main reason first time buyers want to buy in the UK, and that option is closed to many.
By now, we have an increasing number of people approaching retirement who are still involuntarily renting, and it's the leading edge of a very large demographic wave of people in that position. I worry about those because rents are getting to be higher than their entire pension will be, and government housing support is insufficient to make up the difference.
