First time buyer - right to buy - previous credit problems.

Hi all,

I am looking for some advice.

I was declared bankrupt in 2006 and discharged the following year. This is no longer on my credit file.

I have 4 credit cards, all with small balances, which I obtained to help rebuild my credit. Vanquis, Capital One, Aqua and Barclaycard Initial.

I have the right to buy on my flat. As I am in inner London, I will receive £100k discount, bringing the cost of my flat to around £80k.

Can anyone advise me regarding firstly whether I would have any chance of getting a mortgage and realistically how much deposit I would need.

Thanks :)
