So, this is the bedroom tax letter that One Vision Housing is harassing tenants to sign. Pay particular attention to the declaratiion:
"I confirm that the above information has been fully explained to me and understand that I will be responsible for paying any shortfall in our rent payments. I understand that One Vision Housing can take legal action against me if I fail to pay my rent including any shortfalls as a result of these changes"
One Vision Housing have just opened a can of worms. Do not sign.
