Debtor Moves In California

Debtor owned a house for 10 years in West Covina, CA. Debtor sells the house and receives $500,000.  Debtor then buys a house in Riverside, CA  and uses the entire $500,000 as a down payment. This gives him $500,000 in equity in the Riverside property.

One (1) year later, Debtor has a car accident and is sued for $100,000 and a judgement is entered against him. 

Debtor now wants to file for bankruptcy in Riverside County.  Is the debtor limited to $189,050 because he only lived in the new house for one (1) year?
