'Seems a bit extreme rnting to get evicted so we could qualify for housing association or housing benefit.'
And that's not automatic.
You have to go through your council's process unti they come up with a decision as to whether you are or aren't intentionally homeless or threatened homeless.
This can take almost all your 2 months notice period, whilst you ring and ring and write and write and wait for their decision whilst the clock ticks down.
And if you think all social housing/HA housing is somewhere you'd actually want to live, guess again!
Oh, yeah, you'll have plenty of points, and they'll offer you first a squat or former squat in dire condition whilst you languish in temporary housing or B&Bs with your family, spending all day on the street or in your car because you have to be out of the B&B during the day.
Then when you say no you'll have a fight on your hands, because the council will come back and say they have fulfilled their legal obligation to you by offering you that shitty shite housing, so they're no longer obliged.
Because newsflash: all the best social/council housing has tenants in it or has been bought.
I wouldn't recommend this or wish it on all but my worst enemies.
You're very lucky.
