Consider not allowing your commercial lenders to do home loans. They're not only not reporting the income correctly many times, but they also can really get you beat up on HMDA. We don't take the risk. They whined, but they no longer do them. This keeps your income calculations in line throughout the bank. If you will let them do these, force them to fill out the same income calculation forms your mortgage folks use.
I have been a lender so I understand both their terminology and the stuff we're stuck to. Let me share part of my "you screwed up the revenue code" email I send out once a year as part of my data integrity review (they have to review 100% of all loans for revenues annually)
The criteria for determining Gross Revenue Codes is as follows:
On each Commercial Loan Information Sheet, under the heading CRA GROSS REVENUE CODE: you are asked to choose one of three options. (1) =< $1 million (equal to or less than); (2) > than $1 million (greater than) or (3) Revenue Unknown.
In the first two choices, the information would be found by reviewing line one of the Income Statement (Profit & Loss Statement) or line two of a Federal Income Tax Return. Typical titles are, Gross Revenues, Gross Sales, Total Sales, Gross Income, Total Income, Gross Rents, Total Rents, etc. For CRA purposes, the gross figure on these documents is the figure used to determine the revenue code, which should be either a 1 or a 2 in 99% of the loans processed. There should be no adjustments to these figures. The request is for GROSS revenues, not net.
If you are relying on another repayment source for the debt in question, the GROSS revenues of that repayment source would be used.
As an example: ABC Company, is a subsidiary of BCD Corporation with annual revenues of $1 dollar. Obviously with these revenues we would expect the repayment source for the obligation to be coming from another source, in this case BCD Corporation whose annual revenues are $14 million. In this example, although the loan was to ABC Company whose revenues are below a million, the correct answer would be revenue code 2, above one million, as the repayment source is BCD Corporation.
The third choice (revenue code 3) should be seldom used, but would be proper if a new borrowing entity with only proforma revenue information available was approved for a loan. In this case, as noted previously, if the repayment source is another entity, that entities gross annual revenues would provide the information necessary to determine a revenue code. If the ONLY revenue information used in the credit decision is the proforma, (very rare) revenue code 3 would be appropriate.
