Mortgage Underwriting and Qualification Questions and Answers — Questions and Answers
Question 1: An underwriter is calculating a borrower's front-end debt-to-income ratio (DTI). Which of the following components is exclusively included in this calculation?
- Student loan payments
- The estimated monthly principal, interest, taxes, and insurance (PITI) for the new mortgage (Correct answer)
- Monthly car loan payments
- Minimum monthly credit card payments
Correct answer: The estimated monthly principal, interest, taxes, and insurance (PITI) for the new mortgage
The front-end DTI ratio, also known as the housing ratio, specifically measures how much of a borrower's gross monthly income will be used for housing-related expenses. This includes the principal, interest, taxes, and insurance (PITI) of the proposed mortgage loan. Other recurring debts like car loans, student loans, and credit card payments are included in the back-end DTI ratio, but not the front-end.
Question 2: A borrower is purchasing a home for $400,000. They have a first mortgage of $320,000 and a simultaneous second mortgage (HELOC) for $40,000 to cover part of the down payment. What is the Combined Loan-to-Value (CLTV) ratio?
- 80%
- 90% (Correct answer)
- 85%
- 100%
Correct answer: 90%
The Combined Loan-to-Value (CLTV) ratio is calculated by adding all loan amounts secured by the property and dividing by the property's value. In this scenario, the total loan amount is $320,000 (first mortgage) + $40,000 (second mortgage) = $360,000. To find the CLTV, divide the total loan amount by the home's value: $360,000 / $400,000 = 0.90, or 90%.
Question 3: Which of the following best describes the primary advantage of an Automated Underwriting System (AUS) in the mortgage qualification process?
- It guarantees loan approval for all applicants.
- It provides a detailed analysis of a property's physical condition.
- It replaces the need for a property appraisal.
- It offers a rapid and consistent initial risk assessment based on established guidelines. (Correct answer)
Correct answer: It offers a rapid and consistent initial risk assessment based on established guidelines.
Automated Underwriting Systems (AUS), such as Fannie Mae's Desktop Underwriter (DU) and Freddie Mac's Loan Product Advisor (LPA), are designed to provide lenders with a fast, objective, and consistent evaluation of a loan application's risk. The system uses algorithms to compare the borrower's credit, income, assets, and other data against the lender's or investor's guidelines. It does not guarantee approval, assess the property's condition, or replace the need for an appraisal.
Question 4: For a VA loan, an underwriter determines that a veteran's debt-to-income ratio exceeds the general 41% benchmark. Which of the following could be a significant compensating factor allowing the loan to still be approved?
- Having a high credit score from only one credit bureau.
- A small increase in the proposed housing payment compared to their current rent.
- Sufficient residual income that exceeds the VA's regional requirements. (Correct answer)
- A letter of explanation for a single 30-day late payment two years ago.
Correct answer: Sufficient residual income that exceeds the VA's regional requirements.
While the VA uses a 41% DTI as a guideline, it places significant emphasis on residual income. Residual income is the amount of money left over each month after all major debts and living expenses are paid. If a borrower's residual income is strong and exceeds the VA's minimum requirement for their family size and region (often by 20% or more), it can be used as a strong compensating factor to approve a loan with a DTI over 41%.
Question 5: A lender must downgrade an FHA loan application that received an 'Approve/Eligible' recommendation from the TOTAL Scorecard to a manual underwrite. Which of the following situations would trigger this requirement?
- The borrower is making a 10% down payment.
- The borrower's credit report shows a total of $1,500 in disputed derogatory accounts. (Correct answer)
- The borrower has been at their current job for five years.
- The property is a single-family residence.
Correct answer: The borrower's credit report shows a total of $1,500 in disputed derogatory accounts.
FHA guidelines require a loan to be downgraded to a manual underwrite if the borrower has $1,000 or more collectively in disputed derogatory credit accounts. Even with an automated approval recommendation, this specific circumstance requires a human underwriter to review the file to assess the risk associated with the disputed accounts.
Question 6: A borrower wishes to purchase a home but has only a 10% down payment and wants to avoid paying private mortgage insurance (PMI). Which financing structure would help them achieve this goal?
- A single conventional loan with an 90% LTV.
- An FHA loan.
- An 80-10-10 piggyback loan. (Correct answer)
- A jumbo loan.
Correct answer: An 80-10-10 piggyback loan.
An 80-10-10 piggyback loan is a structure designed specifically for this purpose. It involves a first mortgage for 80% of the purchase price, a second mortgage for 10%, and a 10% down payment from the borrower. Because the first mortgage has an 80% loan-to-value (LTV) ratio, it avoids the requirement for private mortgage insurance (PMI), which is typically required for conventional loans with an LTV above 80%.
