3 Simple Steps to Solve Your Problem:

1. Find a Free Company with a house. Should be easy enough, there are always FCs looking to recruit, even with houses.
2. Join that FC. Again, should be easy enough.
3. Buy an FC room for 300k.

Subsequently, there may be a couple of other steps, both optional and possibly impossible for you:

4. Quit whining. SE screwed up with housing, true, but they've acknowledged their mistakes and apologised for them.
5. Don't get kicked from your new FC. Given your behaviour here, I'm sure it'll be a task of Herculean proportions for you.
