How Much Should I Charge for Renting One Room in My Condo. Should I Request Half of the Mortgage?

mortgage

I reckon I found the right person to be my roommate, the problem is that I dont know how much to charge her for rent. I dont know how much people pay when renting just one room. I want to tell her to pay half of the mortgage which would be $500.00. Is this too much? Help please!
well i will be living there 2 and utilities are included
