Your credit rating could be going up. Fair Isaac's, the company that calculates FICO credit scores, is changing the rules on what can and can't impact your number.

During the recession, a lot of people with good credit took some hits, so credit experts said this is a game-changer for millions of people and for lenders.

If you have medical debts or paid off collections on your credit, your credit score could jump around 25 points this fall.

"I think it could mean a difference between you qualifying for a loan and not qualifying for a loan," said Steve Stelzman, with The Mortgage Company in Allentown.

While bad medical debt is a major issue for many people, Stelzman said the FICO changes will make it easier for people with a few mistakes on their credit to get better loans. It will also help lenders better assess risk.

Alan Jennings, with Community Action Committee of the Lehigh Valley, said the FICO change is good for the economy, for families and for neighborhoods, but he said more needs to be done to keep another sub-prime lending crisis from happening.

"One of the fears that we have is that the financial institutions that do both kinds of lending would steer people to the more expensive lending. Typically, if you have less of a credit score, the cost of the loan is greater," said Jennings.

Jennings said anyone considering applying for a mortgage should get home-buying counseling beforehand, so they know what they are getting themselves into and what they need to do to make prudent financial decisions.

CACLV has several seminars of this kind each year.

While the changes are set to take effect this fall, it could be a while before they show up on your report.
