thank you, I know this is a lot of information, but they actually don't pay any rent or mortgage payments on our home. They inherited it through family, and really only pay utilities on the house as their parents pay property taxes and home owners insurance. I was trying to take that into consideration when determining how much of my own support I provide, and believe I meet the threshold of over 50%. I'll try talking with my parents about it to save the headache of amendments, and will refer to the IRS publication overviewing the rules for claiming a dependent. thanks again!
