Right my DS 23 has asked about moving back in, he has despite all my warnings/budgeting help etc managed to run up around 8/9k of debt. I haven't seen the exact amount as yet. This he admits has been done by being stupid, holidays, festivals, nights out, take aways etc etc. His lease runs out in 2 months time, so he wants to come back save and pay his debts off. He's asked me to come up with an amount to charge him, how much do I say? He says he will buy own food, but things like tea, coffee, milk, sauces etc that would be silly. So I know there is the extra 25% council tax will cost me with another adult but how much extra does one person cost in gas/electric? I don't know where to start to even come up with an amount. The other thing I was thinking is do I say an amount, put anything less than it actually costs me into a savings account and when it gets to a decent amount give it him to pay off something? Or is that not getting him to take responsibility for the mess he's made of everything?
I will be sitting down with him to do a proper budget and see what his minimum payments/interest rates are on what. I think from what he's said I may feel like killing him after that!
