And you want as many opportunities as possible.
But opportunities must be seized! Whether you want to keep your home by getting a loan modification, or you just want to avoid foreclosure for as long as possible so you can save money before giving up your home, you should seize the opportunities available to you by contesting the foreclosure lawsuit against you.
