I would say have her pay the cable bill and the electric/gas bill (don't do food, IMO it always gets messy b/c it ends up costing a lot more), no reason she gets  to live completely free... remember, you're still on the hook for maintenance for both homes, and stuff will come up! 

On the other hand, neighborhoods with no HOA sometimes can get really unorganized, messy and lack pool and playground, etc..
