People who live in the city will know that it can cost you an arm and a leg for four walls and a roof over your head.
Don't even get us started on the commute to work as some city dwellers will have to catch trains, buses and ferries to make it on time to work.
However, that pales in comparison to a woman who calls herself a 'super commuter'.
Sophia Celentano doesn't have to come into the office of her corporate marketing internship in New Jersey every day, so she opted to live a little outside the city to avoid paying massive rent.

But when we say a 'little' outside the city, we actually mean it's a lot.
It's a casual 700 miles away.
When she has to venture into the office, she catches a flight from South Carolina to New Jersey.
Her day starts at 4am so that she has enough time to get ready and get to the airport for her 6:30am flight.
Sometimes she will catch a 6am flight and it gets her into New Jersey at around 7:30 to 8am and then she will catch an Uber to her work to make it in the doors before 9am.
Then, she has to do all that again but in reverse at the end of the day.
Once her work day finishes at 5pm, she trundles back to the airport to fly to South Carolina and then drives home.
She claims she saves way more money living in her family home than moving her whole life over to the eastern US state for the 10-week internship.
When she adds up the flights, Ubers and unexpected things, she's worked it costs her around $2,250 to be a super commuter.
However, if she was to move to New Jersey then she reckons she would be paying around $4,250.
She told her followers: "I am saving a good amount of money living at home I don't have to pay rent and I don't have to pay money for food."
People online were truly baffled by the revelation and say it would be too much for them.
"That must be so stressful and expensive," said one user.
Another added: "I love this for you but i could never handle the stress of it all."
Others also praised how time efficient she was, with one person saying: "The fact that you fly to another city and get to work by 9 when I live 10 mins away and am always late."
True, you all now have no excuses to be late.
