Mortgage Underwriting Guidelines & DTI - (@Bill Gulley)
In another thread, @Bill Gulley and I had a brief discussion on underwriting guidelines. Rather than take that thread off topic, I created this one to hopefully further the discussion. The main contention was whether a lender will consider excessive availability of revolving credit (large open credit card limits) as a negative in calculating your ability to pay or DTI.

@Bill Gulley, I hope you'll take some time to discuss this as it is of great interest to me and you seem knowledgeable in this area. To clarify, I underwrite loans and sell insurance. I don't underwrite for an insurance company.
I researched the Fannie Mae guidelines a bit since I have no experience with this type of entity. I did find a list of guidelines at: https://www.fanniemae.com/content/guide/selling/b3... titled: B3-6-02: Debt-to-Income Ratios (09/29/2015)

There is a specific section addressing this topic:
___
Calculating Total Monthly ObligationThe total monthly obligation is the sum of the following:
- the monthly housing expense of the borrower's principal residence (or the qualifying payment amount if the subject mortgage loan is secured by the borrower's principal residence (see B3-6-03, Monthly Housing Expense));
- the qualifying payment amount if the subject mortgage loan is secured by a second home or investment property (see B3-6-04, Qualifying Payment Requirements);
- monthly payments on installment debts and other mortgage debts that extend beyond ten months;
- monthly payments on installment debts and other mortgage debts that extend ten months or less if the payments significantly affect the borrower

If you have a credit card that has a zero balance and the credit limit is 10,000 or whatever this will not affect your DTI.
DTI is based on payments not your debt.
Fannie Mae used to make you close your c.c. account if it was being paid off through the loan. They recently changed this and now the account doesn't need to be paid off.
Example on DTI
Mr. Jones makes 10,000 a month gross and is a wage earner. He has the following debts:
Capital one card: Balance $10,756 Payment $202
Ford Motor Credit: Balance $33,987 Payment $309
H.E.L.O.C.: Balance $90,000 Total that can be drawn $100,000 (in this case the UW will calculate the payment based on $100,000) PAYMENT 400
New First Mortgage: $200,000 Payment $1500 (Including taxes and insurance)
Total DEBT: 344, 743 Total PAYMENTS: 2,411
In this case the DTI will be 5.11/24.11 now during the refinance you don't want to use any c.c's because it could affect your DU/LP findings. This is why good loan officers tell you not to buy, co sign or use any credit cards and if you can avoid using any reserves.
Just as a side not I think DTI ( debt to income ratio ) should be changed to PTI ( payments to income ratio)
I hope this helps and I speak about this briefly in my interview on the Joe Fairless Show earlier this year. The link is on my profile.
Have a great day.
