But you still haven't explained how you are going to have the property in your name - I don't think you'll be able to as it's your friends right to buy, not yours.
You may have to 'loan' him the money to buy the property in his name and then have the deeds transferred (although I don't even know if this would be possible but I think I remember reading something about time scales). That's a huge risk though - what if something happened to him whilst the property was in his name?
I'm surprised that this all appears to be easy for you. There should be no way possible for you to buy a property from the council in these circumstances. Affordable houses to rent are much harder to come by these days and 'first time buyers' are mortgaging at levels higher than ever before. I understand it's a good opportunity for you and I suspect most people would jump at the same chance. However, I think there should be much stricter rules to prevent this from happening. Personally, if I knew you I would be telling the council of your plan - so beware of who knows about this.....I'm just a normal person who really just wants a quiet life - so If this can annoy me a little it is going to seriously p155 most people off.
