Mortgage financier Fannie Mae is toughening its mortgage application decision-making process effective Monday, June 2, 2008.

The new guidelines will force many Americans to face higher mortgage rates, higher loan fees, or to be shut out from “prime” mortgage rates altogether.

The new “mortgage rules” include the following changes:

1. Higher income levels required for basic approvals
2. Interest only loans are now considered high-risk
3. Condos are now considered high-risk
4. 60-day mortgage lates within 6 months are a major red flag

Not all of the changes are for the worse, though.

In the new guidelines, self-employed borrowers will no longer be viewed as more risky than a W-2 employee. This will help small business owners and commission salespeople get more mortgage approvals than in the past.

Fannie Mae agreed to honor all mortgage approvals granted prior to its changes, so if you’ve been putting off that pre-approval, consider talking to your loan officer before the weekend starts.

Your mortgage approval will be much more lenient today than if you wait until Monday.
