The truth is to understand mortgages can be a secret worth exploring. Mortgages have changed, but has the changed been for the better. If the change is for the better remains to be seen, but it is important to note that change has occurred. The changes are:
The end of February beginning of March of 2009, the lenders increased the minimum credit score to 620. Lenders increased the minimum credit score to this amount due to changes to the secondary lender market. The lenders viewed this increase in credit score limits as a safeguard to the uncertainty of the secondary lender market. The lenders feared that by the time a loan was ready to close and it was time to sell it to the secondary market that the borrowers could no longer qualify for the longer due to regulatory changes to credit score and lending guidelines.
Incidentally, how lending works is that a front line lender like Chase finances your loan, then sells it to the secondary market, Fannie Mae or Freddie Mac for a portion of what the original loan is so that Chase can have cash available to make the next loan.
