You forgot to add that he or she must have financial intelligence too unless he would run back to the parent's house by the time the rent expires and he can't renew again.When once you have been able to pay your rents, you can actually start living alone. There is nothing like amount. All you need is your house rent and a source of income.
Wow, you are lucky, the rent of your apartment is inclusive of your electric bills and internet. Even if you use the aircon day or evening, the rent remains the same. But I have my own home. I have not experience living alone.After leaving my parents' house, I had to come up with money for rent, a deposit, household items, and other expenses. Initially, I was unsure what amount I needed, but I estimated it to be around $800. Now that I am settled, I do not need to spend as much since I already have everything I need for my apartment. My main expenses now are just food and some bills. The rental cost include electricity, internet, and water.
