If you're able to run the business from a home office without distractions then I would just stay at home instead of spending the rent money for office space.
But if you're distracted while working from home office or would feel better and more productive then an office space could be worth it.
Personally for me unless I had other employees then I would continue to work out of a dedicated home office to save money.
You can also write your home office on your tax deductions when you file your income tax so that can be another added benefit.
