Earlier quoted context omitted.
Most employers provision ~100sq/ft per employee. In SF real estate goes for $50-$70 per sq/ft per month. Obviously there’s negotiating that happens. You could do a lot of travel with a 5-7k budget per month. There are a ton of variables- agree more analysis is needed.
Office rentals are quoted at dollars per square foot per year so divide that number by 12 and you realize it's not that large after all.
But yes, you're right that typical high rise office space in the bay is around $50-80/sf/year or $4.50-7/sf/mo. Or $450-700/mo per employee at 100 sf per employee.
