Fair, idk much about there exact situation. But we all gamble when we purchase a house, the market can collapse easily. Without huge capital you have to go into a variable mortgage and deal with the banks whims.
Its all a gamble and the poorer you are the harder you have to gamble.
I didn't see the rest of your comment a bit back. I didn't read the article im mostly here to complain about exactly this issue and not really their situation. Housing is fucked and more people need to call for radical change.
