The add reads "$1,000+ per month". My assumption here is that depending upon your lifestyle, you may have expenses that aren't being covered. These expenses can be anything. (Alcohol, subscriptions, any costs you incur at your school, fun things you choose to do on your day off, clothing, etc...) But the basics are covered. As stated previously, this is not a great deal. This is not something I personally would ever consider taking, nor is it something I would offer to a potential employee. However, this does not meet the choosing beggar standards either. I've seen posts on here asking people to babysit for $20/week. Usually the live-in nanny positions posted on here are akin to "you only owe me $800/month for living here if you babysit my kids for free 40hrs/week." This is a low-end but semi-reasonable offer.
