From NORML:

Sale or Cultivation
2 oz or less gift class B misdemeanor 3 months and/or fine $500
24 g sale class A misdemeanor 1 year and/or fine $1,000
25 g to 4 oz (first felony) class E felony 1 - 4 years


...so the question is, cut and dried, is it under 25 grams? If so you lookin at a misdemeanor and a 500 dollar fine. If it's more, you could be charged with a felony.

Either way, they won't take you parent's house. There are Supreme Court cases against property seizures that are "grossly out of proportion to the offence", so any good lawyer could prevent that.
