@dazza_73 Follow this OP.
And if at all possible and you don't mind, RM 500 for your aunt's room might be an alternative. Having a family member close by can be beneficial in many aspects (Safety, Help, etc)
@meesh1070 Might be a bit mean but tell them you will start supporting them more financially only if they start spending responsibly. For example they track their day expenses and show it to you.
Also if you're the only child and if they are willing, have them transfer the house in your name...
