A foreclosure will negatively impact a homeowner's ability to obtain future mortgages more severely than a short sale. A foreclosure will mean a homeowner cannot get a Fannie Mae loan for 5 years, will lower their credit score up to 300 points for over 3 years, and will remain on their credit report for 10 years. It can also impact security clearances and employment. A successful short sale allows for Fannie Mae loans after 2 years, lowers credit scores only 50 points for up to 18 months, is not reported on credit reports, and does not impact security clearances or employment.
