My question involves bankruptcy in the state of: CA

I am living in a home that was my Investment property in 2006 - 2008. My question is if I move out now, and file BK 13 from a property I am renting will I be able to cram down my mortgages to the current value of the property.

I have filed taxes reporting this property as an investment in 2007 & partially in 2008.

Could an issue arrise since I temporarily moved in to the property? It is far too small for my family. We only have 725 sqft for a family of 3. The mortgages taken out in 2006 were under Full Doc Investment Guidelines.

I appreciate your response.
