Mortgage Underwriting and Qualification — Questions and Answers

Question 1: A borrower has a front-end DTI of 31% and a back-end DTI of 45%. Which conventional loan guideline does this violate?

Front-end limit of 28%
Back-end limit of 43% (Correct answer)
Front-end limit of 33%
Back-end limit of 50%

Correct answer: Back-end limit of 43%

Standard conventional loans typically cap the back-end (total) DTI at 43%, so 45% exceeds this threshold.

Question 2: Which income type requires a two-year self-employment history to be considered stable by most underwriters?

W-2 salary income
Self-employment income (Correct answer)
Pension income
Social Security income

Correct answer: Self-employment income

Underwriters typically require a two-year self-employment history documented by tax returns to verify stability and consistency.

Question 3: What is 'compensating factors' in mortgage underwriting?

Fees charged to offset underwriting costs
Positive attributes that offset a borrower's weak credit profile (Correct answer)
A formula for calculating loan-to-value ratio
Discount points paid to reduce interest rate

Correct answer: Positive attributes that offset a borrower's weak credit profile

Compensating factors are strengths such as large reserves or low DTI that can offset weaknesses like a borderline credit score.

Question 4: A property appraisal comes in $15,000 below the purchase price. What typically happens to the loan amount?

The lender automatically raises the loan to match the purchase price
The loan is based on the appraised value, not the purchase price (Correct answer)
The borrower can ignore the appraisal gap
The seller must reduce the price by law

Correct answer: The loan is based on the appraised value, not the purchase price

Lenders base the loan on the lower of the appraised value or purchase price, so the borrower must cover the gap or renegotiate.

Question 5: Which document is used to verify a borrower's employment and income directly with their employer?

Form 1003
Verification of Employment (VOE) (Correct answer)
Form 4506-C
Closing Disclosure

Correct answer: Verification of Employment (VOE)

A Verification of Employment (VOE) form is sent directly to the employer to confirm job status, tenure, and income.

Question 6: What does 'layered risk' mean in the context of mortgage underwriting?

Multiple insurance policies on one property
Several risk factors present simultaneously on a single loan file (Correct answer)
Stacking discount points on a loan
Having co-borrowers on the application

Correct answer: Several risk factors present simultaneously on a single loan file

Layered risk refers to multiple risk factors — such as low credit score, high LTV, and high DTI — appearing together, increasing the chance of default.

Question 7: A borrower wants to use gift funds for a down payment on a conventional loan. What is typically required?

A signed gift letter and documentation showing the funds were transferred (Correct answer)
Nothing extra — gift funds are always acceptable without documentation
A notarized deed of gift from the donor
The donor must be a blood relative only

Correct answer: A signed gift letter and documentation showing the funds were transferred

Conventional guidelines require a gift letter stating no repayment is expected, plus bank statements or wire records confirming the transfer.

Question 8: Which credit score model is most commonly used by mortgage lenders in the U.S.?

VantageScore 3.0
FICO Score 8
FICO Mortgage Score (Versions 2, 4, 5) (Correct answer)
Experian PLUS Score

Correct answer: FICO Mortgage Score (Versions 2, 4, 5)

Mortgage lenders typically use FICO Score versions 2, 4, and 5 from the three major bureaus, which are mortgage-specific scoring models.

Question 9: What is the minimum credit score generally required for an FHA loan with a 3.5% down payment?

500
580 (Correct answer)
620
640

Correct answer: 580

FHA requires a minimum 580 credit score for the 3.5% down payment option; scores between 500–579 require 10% down.

Question 10: In underwriting, what does 'seasoning' of funds refer to?

The age of the mortgage loan
How long funds have been in the borrower's account (Correct answer)
The interest rate adjustment period
The time since last late payment

Correct answer: How long funds have been in the borrower's account

Seasoning refers to how long assets have been in the borrower's account — typically 60 days — proving they are not borrowed funds.

Question 11: Which of the following is NOT counted in a borrower's monthly debt obligations for DTI calculation?

Student loan payments
Car insurance premiums (Correct answer)
Minimum credit card payments
Auto loan payments

Correct answer: Car insurance premiums

Insurance premiums are not installment or revolving debts, so they are excluded from the back-end DTI calculation.

Question 12: What triggers an automated underwriting system (AUS) to require manual underwriting?

A borrower with a perfect credit score
A 'Refer' or 'Caution' finding from the AUS (Correct answer)
A conventional loan application
A salaried W-2 borrower

Correct answer: A 'Refer' or 'Caution' finding from the AUS

When AUS returns a 'Refer' (Fannie Mae) or 'Caution' (Freddie Mac) finding, the file must be manually reviewed by an underwriter.

Question 13: A borrower earns $6,000/month and pays $1,800/month toward all debts including the proposed mortgage. What is their back-end DTI?

25%
30% (Correct answer)
35%
40%

Correct answer: 30%

$1,800 ÷ $6,000 = 0.30, or 30% back-end DTI.

Question 14: What is the purpose of the 4506-C form in the mortgage underwriting process?

To order a property appraisal
To authorize the IRS to release tax transcripts to the lender (Correct answer)
To verify the borrower's employment
To request a credit report

Correct answer: To authorize the IRS to release tax transcripts to the lender

Form 4506-C allows the lender to obtain tax return transcripts directly from the IRS to verify the borrower's reported income.

Question 15: A borrower has two mortgage late payments in the past 12 months. How does this typically affect FHA loan eligibility?

No impact — FHA ignores recent lates
It may result in a downgrade to manual underwriting or denial (Correct answer)
It automatically disqualifies the borrower permanently
It only affects the interest rate, not eligibility

Correct answer: It may result in a downgrade to manual underwriting or denial

Recent mortgage lates are a significant red flag; FHA guidelines may require manual underwriting and increase scrutiny or result in denial.

Question 16: What is the standard waiting period after a Chapter 7 bankruptcy before a borrower can qualify for a conventional loan?

1 year
2 years
4 years (Correct answer)
7 years

Correct answer: 4 years

Fannie Mae and Freddie Mac require a 4-year waiting period after Chapter 7 bankruptcy discharge before conventional loan eligibility.

Question 17: Which of the following best describes 'reserves' in mortgage underwriting?

The lender's capital set aside for loan losses
Assets remaining after closing that could cover future mortgage payments (Correct answer)
The escrow account balance
The appraisal contingency fund

Correct answer: Assets remaining after closing that could cover future mortgage payments

Reserves are liquid assets remaining after the down payment and closing costs that demonstrate the borrower's ability to weather financial disruptions.

Question 18: What is a 'non-arm's length transaction' and why do underwriters scrutinize it?

A sale between strangers with no prior relationship
A sale between related parties or those with a personal connection that could affect the price (Correct answer)
A loan without a co-borrower
A transaction with no seller concessions

Correct answer: A sale between related parties or those with a personal connection that could affect the price

Non-arm's length transactions (e.g., family sales) may have inflated or deflated prices, so underwriters apply extra scrutiny to ensure fair market value.

Question 19: For a VA loan, what replaces the traditional PMI requirement?

A VA Funding Fee paid upfront or financed (Correct answer)
Monthly MIP like FHA
A separate VA insurance premium
There is no cost — VA loans have no insurance requirement

Correct answer: A VA Funding Fee paid upfront or financed

VA loans charge a one-time VA Funding Fee (which can be financed) instead of ongoing monthly mortgage insurance.

Question 20: What does a 'conditional approval' mean in the underwriting process?

The loan is fully approved and ready to close
The loan is approved pending receipt of specific additional documents or clarifications (Correct answer)
The loan is denied but can be appealed
The borrower must find a new property

Correct answer: The loan is approved pending receipt of specific additional documents or clarifications

A conditional approval means the underwriter approves the loan in principle but requires certain conditions — like updated pay stubs or a letter of explanation — before final clearance.

Question 21: A self-employed borrower shows $120,000 gross income on their business return but takes $40,000 in deductions. What income does the underwriter typically use?

$120,000 — gross business revenue
$80,000 — net after business deductions (Correct answer)
$40,000 — only the deduction amount
$160,000 — gross plus add-backs

Correct answer: $80,000 — net after business deductions

Underwriters generally use net income from Schedule C after deductions, though some non-cash deductions like depreciation may be added back.
