I live in California. My mother has owned a house for 5 years. A few years ago, before the market started to dip, she took out a second to pay off credit card bills. Last year, she bought my brother a condo in another city. Now, she can't afford both mortgages and owes more than the house is worth. She's considering letting her house go into foreclosure and just moving in with my brother.
Will a foreclosure on her house affect my brother's condo? Her co-worker told her that the bank can sue her and/or put a lien on my brother's condo. Is that true?
