From the website, it looks like the requirement is before beginning, not before acceptance. I’ll have to think about it - in my case it’d just be a micro class. I placed out of introductory micro via AP, but that was a long time ago.
You should check out the MIPP program. It's for more experienced professionals like you and it's only one year. With the MAIR, you'd be paying for an extra year of tuition (ouch) and you'd be in class with people who are much younger, although I'm not sure if this matters to you. The average age of a SAIS MAIR student is 25-26.
If your heart is really set on the MAIR, getting there is pretty straightforward: take micro and macroeconomics and get A's in both. If you don't have a statistics course on your undergrad transcript, do that too and get an A. If you got a good grade in your undergrad calculus course, that should suffice. I don't think there is any need to take econometrics, as it's not a requirement of the SAIS core and you can avoid it when you get to SAIS if it doesn't align with your interests.
