The way to think about this sub is like an extremely conservative aunt or uncle. The sub is never going to be comfortable with anyone paying anything more than 1/3rd of their salary for rent. And in your case it's like 50 percent to 93 percent of your take home salary.

That being said, I've known folks pay higher than 1/3rd and do okay for many years. So it's really upto you. If you reliably get commissions of at least 2500 each month, i think its not unreasonable.
