Your home county can determine your eligibility to file Chapter 7 bankruptcy. If you are a high income household--a single person making more than $61,000 or a family of four making more than $110,000--you have to show your income eligibility according to the bankruptcy means test formula. That formula allows much higher rents for people in Loudoun and Fairfax than in Prince William. About $400 more a month for a single person; $500 for a family of four. What does that mean?
