but property is still very affordable in many other parts of the country
"Affordable"
Yes, to those who can "Afford" them.
Let's say person A lived at home with parents, parents who could afford to charge little bond / rent etc, they studied at Uni, went abroad and worked for decent money, met someone that did similar, pooled their resources and bought a house.
Now, just try to imagine person B that didn't have that life, didn't have those parents, didn't meet that partner, couldn't go to uni or couldn't work abroad. I know it's hard to imagine that maybe person B couldn't buy a house and is having to rent.
It's all relative, OPs life isn't every one's life. Everyone's life is different and they all have different routes. Sitting with wide eyed wonder and questioning why other people with different experiences, different opportunities, different childhoods etc didn't do the same as you is stupid, illogical and a waste of time.
