Working with a client, maybe a first time home buyer that was not able to get pre-approved? One option for them may be a credit re-scoring. This is just one of many reasons why I have relationships with local lenders who work with our client to get them approved. Keep in mind, there are no "wrong answers" when getting pre-approved for a loan. If the client can't get approved now, a good local lender can provide guidance of things the client can do (IE improve their FICO score), so that home ownership can be part of their future.
Using credit simulation programs, lenders can predict what effect actions by clients/consumers will have on their credit score. The most common action is paying down or paying off revolving balances that are at or near their limit. The lender can then have the client/consumer pay down the account and provide a screen shot to the lender of the new balance. The lender can then order a rapid re-score through one or more of the credit repositories.
This is most commonly done for clients/consumers (first-time buyers, for example) who are below the minimum threshold for credit scores to be mortgage eligible in an attempt to get them up to the minimum standards. It can also be effective to raise credit scores for consumers who have the minimum credit score but who would receive a lower interest rate and lower mortgage insurance charge with a higher credit score (typical on conventional loans).
This is a free service to the consumer and the lender is not allowed to charge for credit re-scoring. This is good for buyers to know, and also the agents that work with buyer's.
