If I were to stop making payments and have my house foreclosed on, can the current mortgage company effect my credit score?

Recently, Fair Isaac, which developed FICO scores, pulled back the curtain a bit, revealing some estimates of point-score declines following mortgage delinquency problems.

Here are the average hit your credit will take:

30 days late: 40 - 110 points

90 days late: 70 - 135 points

Foreclosure, short sale or deed-in-lieu: 85 - 160

Bankruptcy: 130 - 240

To come to these figures, Fair Isaac created two hypothetical consumers, one who starts out with a fair-to-middling score of 680 and the other with a very good one of 780. (FICO scores range from 300 to 850.)

The hypothetical person with the 780 FICO has 10 credit accounts versus six for the 580, plus a longer credit history, lower utilization of total credit limit and no missed payments on any account. The other consumer has two slightly damaged accounts. Neither have any accounts in collection or adverse public records.

See the chart above to see how each scenario affected each borrower.

Notice that for both borrowers a single one-time black mark results in steep drops, but it is when they fall further behind that things get really harsh, according to Craig Watts, a spokesman for Fair Isaac.

"The lending industry tends to regard an account differently when it has become 90 or more days late," he said, "The likelihood that consumers will resume paying their overdue obligations drops off significantly after the delinquencies have reached 90 days."

One reason credit companies were so closed-mouthed is that they often can't definitively state how much each delinquencies will affect scores because there are too many variables.

Answer: Yes, your credit score will suffer.
