Constructor - Cheat

If you are getting too many black marks from the council, get a level two house, and make the tenants 'the punks.' After a
while they should start to complain about a hedge and will give you black marks if you do not drastically decrease their rent.
Drastically decrease their rent, and you will receive some white marks. Then put it up again and repeat this until you have no
black marks left. Then either replace them, agree to their demands or make them have children. P.S. if you continue to do this,
you will receive many white marks which can be exchanged for cash. (100 marks for 10,000.)
