I genuinely don't understand the concept of charging your children "rent" to live in their own home. Wouldn't you rather help them by allowing them to save as much money as possible (especially in this current economy) instead of taking money from them which may reduce the amount that they can save each month, resulting in it taking them a bit longer to move out?
I bought my own property on my own aged 25 and would have never been able to achieve this if I wasn't allowed to stay at home rent free and save as much of my salary as I could. Can I just add, I contributed to the household in other ways e.g cooking for the family weekly, cleaning etc.
I totally understand charging your children rent if you are on a lower income and genuinely need the money, but if this is not the case for you, why do you charge your children rent?
