Credit Score

Foreclosure - May be lowered anywhere from 250-300 points.

short sale - late payments will show and after the sale mortgage will be reported as paid or negotiated for less than full.  This will lower the score as little as 50 - 100 points if all other payments are being paid on time. 

Credit History

Foreclosure will remain as a public record on a person's credit history for 10 years or more.

Short sale - is not reported on a credit history.  There is no specific reporting item for "short sale".  the loan is typically reported "paid in full, settled".
