The economy has put a strain on thousands of households across the nation. In these tough times, many homeowners are struggling in the face of foreclosure. What are the consequences of defaulting on your loan? And what can you do to prevent this loss?

One of the most startling impacts of a foreclosure appears on one's credit report. Your credit score may plummet by 200 to 300 points. In this economic climate, where credit lending standards are already tightened, you may then find it difficult to do everything from buying a car to renting an apartment. What's worse is that the notation of foreclosure stays on your report for up to seven years.

Next, you may owe the lender money. They backed a loan on a home worth X amount. If they sell your home at foreclosure for less than that amount, you may be responsible for the difference. Many states have laws protecting you against this action, but speak with an attorney to find out for what you may be liable.
