depends what you define as comfortable. doable certainly yes. 1400 for rent may be doable but add another 250+ to that for utilities. 800/ month on groceries, you will need a car so unless you can buy one outright figure 250/ month for something decent. $100 a month for gasoline, 100 a month for car insurance, 100 a month (averaged out) for car maintenance. You’re at $3k/ month with all that leaving you $1600/ month after that. Eat out once a week at 50 bucks 1400 bucks left a month
