When your loan is submitted for underwriting, it goes directly into the hands of an underwriter whose job is to determine your "creditworthiness" or your ability to repay the loan. An underwriter takes into consideration the following aspects when deciding whether or not to approve your loan:
In looking at your ability to repay the loan, your job stability and gross income (in relation to your expenses) are critical. Most income must be verified as having been received for at least two years to be used for qualifying purposes.
The underwriter wants to see your net worth, determined as: the money you have available for a down payment, closing costs, cash reserves (money left over after closing of escrow to cover 2-3 months mortgage payments) and other liquid assets. The underwriter also will want to see the "source of funds" - where the money for the down payment and closing costs is coming from. Don’t move money around (pay off bills, receive a gift, etc.) without first consulting your loan officer about the best way to do it, since it may affect the underwriter’s view of your loan.
The underwriter will be concerned with the amount of debt you have because it affects your qualification and ability to repay the loan. Excessive use of credit may not be looked upon favorably.
Because the property is the lender’s collateral for the loan, the value, marketability and condition of the property are extremely important. The underwriter looks at the appraisal for this information, and generally verifies that the appraisal and the purchase price are in the same ballpark
