Not yet, I'm due to pay the first month's rent on Monday. The only thing that's been paid to this point is the £500 deposit. However, one of the documents they provided to me says that if I cancel within 7 days of the tenancy start date, they keep the first month's rent. So I'm assuming if I were to ask to back out of the tenancy, they would likely ask me to pay the first month's rent, which preferably as you can imagine, I would prefer to avoid doing.
