The
score (numerical representation of your credit profile) is not affected. Address is reported as part of your id information (id info is not in the formula for the score).
It is normal procedure for a lender to ask for a previous address if one stays at a current address for less than 2 years (when one finances an automobile). It is an important factor that lenders take into consideration, no doubt.
When one recently moved into the country and credit report shows 3 addresses (if one chooses to report temporary addresses with a bank) instead of 1 in the past 6 months, I do see how it changes anything in the eyes of a creditor.
My point - it is important to start accruing your residential stability, however it should not get in the way of more practical settling decisions.
My knowledge might be outdated though, cause it's been a while.
But my score is up to date:
Creditkarma is a great service (being free), however as I read their articles and suggestions I found some of them misleading (in some instances purposefully).
