Purely from a financial perspective first -
- Calculate your one time expenses for the move: New house purchase - sale of your old house, the cost of physically moving, etc.
- Calculate your ongoing changing of expenses: New higher property taxes, savings on gas and wear and tear on a car (assuming you drive), savings on public transportation (assuming you train it in), etc.
It sounds like it might be roughly net zero, perhaps slightly in the red. BUT this decision isn't purely a financial decision - how much do you hate commuting and physically being in an office? How much more would you prefer to work at home? Are those desires equal to or more than the amount you'd be in the red? Remember, mustachianism isn't about spending the least amount of money possible, it's about your quality of life. Sometimes your quality of life does increase by spending more/saving less. Would it be worth working 3, 5, 10 more years if you could work from home?
