Real Estate License Loan-to-value and Debt-to-income

Last updated: May 2, 2026

Loan-to-value and Debt-to-income questions are one of the highest-leverage areas to study for the Real Estate License. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.

The rule

Lenders use two core ratios to decide whether to approve a residential mortgage. Loan-to-value (LTV) measures the loan amount against the property's appraised value (or sale price, whichever is lower) and protects the lender from collateral risk. Debt-to-income (DTI) measures the borrower's monthly debt obligations against gross monthly income and protects against borrower default risk. Federal regulations under the Truth in Lending Act's Ability-to-Repay rule (12 CFR §1026.43) require lenders to verify a borrower's capacity to repay, which makes DTI central to qualified mortgage status.

Elements breakdown

Loan-to-Value (LTV)

The ratio of the loan amount to the lesser of appraised value or sale price, expressed as a percentage. Higher LTV means the lender bears more collateral risk.

  • Loan amount divided by appraised value
  • Use lower of value or sale price
  • Above 80% typically requires PMI
  • Conventional cap commonly 95–97%
  • FHA permits up to 96.5%
  • VA permits 100% with eligibility

Common examples:

  • A $240,000 loan on a $300,000 appraised home yields an 80% LTV
  • A $285,000 loan on the same home yields a 95% LTV and triggers PMI

Combined Loan-to-Value (CLTV)

The ratio of all liens secured by the property (first mortgage plus any junior liens or HELOCs) to the appraised value. Lenders evaluate CLTV when a second loan is involved.

  • Sum of all secured liens
  • Divided by appraised value
  • Used for piggyback or HELOC scenarios
  • Often capped near 90–95%

Front-End DTI (Housing Ratio)

The percentage of gross monthly income consumed by total housing payment, abbreviated PITI: principal, interest, taxes, and insurance, plus HOA dues and any mortgage insurance.

  • Total PITI divided by gross monthly income
  • Includes HOA and mortgage insurance
  • Conventional guideline often ≤28%
  • FHA guideline often ≤31%

Back-End DTI (Total Debt Ratio)

The percentage of gross monthly income consumed by housing payment plus all other recurring debt obligations such as auto loans, student loans, minimum credit card payments, and court-ordered payments.

  • PITI plus all monthly debt obligations
  • Divided by gross monthly income
  • Conventional guideline often ≤36–45%
  • QM safe harbor caps at 43% historically
  • FHA guideline often ≤43–50% with compensating factors

PMI Trigger and Cancellation

Private mortgage insurance is required on conventional loans when LTV exceeds 80% and follows the Homeowners Protection Act for cancellation rules.

  • Required above 80% LTV at origination
  • Borrower may request cancellation at 80%
  • Automatic termination required at 78%
  • Based on original amortization schedule

Common patterns and traps

Sale Price vs Appraised Value Swap

A scenario gives both a contract sale price and an appraised value that differ, then asks for LTV. The trap choice uses sale price when appraised value is lower, or vice versa. Lenders always use the lower figure as the denominator because they will not lend against value the property does not have.

A choice that calculates LTV using the higher of the two numbers, producing a flatteringly low ratio.

Front-End vs Back-End Confusion

The stem asks for one DTI ratio but a wrong choice computes the other. Front-end uses only PITI; back-end adds all recurring debts. Candidates who skim the stem grab the first plausible percentage that matches their arithmetic.

A choice that adds car payments and credit cards when the question asked only for the housing ratio.

PMI Threshold Misstatement

Wrong choices state that PMI cancels at 80% automatically, or that it can be requested at 78%, reversing the Homeowners Protection Act sequence. The correct sequence: borrower may request cancellation at 80%, and the lender must automatically terminate at 78%, both based on the original amortization schedule.

A choice claiming the lender must drop PMI the moment the borrower hits 80% equity without any borrower action.

Gross vs Net Income Substitution

DTI uses gross monthly income — pre-tax. A trap choice silently uses take-home pay or net income, producing a wrong ratio. Watch the stem for any mention of taxes withheld or a net figure presented to mislead.

A choice that divides debt by an after-tax paycheck figure rather than the gross salary divided by twelve.

Ignoring HOA or Mortgage Insurance in PITI

PITI for ratio calculation includes HOA dues and any required mortgage insurance premium when the property has them. A trap omits HOA or PMI from the housing payment, understating the front-end DTI.

A choice that uses only principal, interest, taxes, and hazard insurance for a condo with stated HOA dues.

How it works

Picture a buyer purchasing a home appraised at $400,000 with a $360,000 loan. Divide loan by value: $360,000 ÷ $400,000 = 90% LTV, which exceeds the 80% conventional threshold and triggers PMI. Now suppose that buyer earns $8,000 gross per month and the proposed PITI is $2,400, with $600 in other monthly debts. Front-end DTI is $2,400 ÷ $8,000 = 30%, and back-end DTI is $3,000 ÷ $8,000 = 37.5%. Both ratios sit within typical conventional guidelines, so the borrower likely qualifies, though the higher LTV adds insurance cost. On the exam, watch for stems that swap appraised value for sale price when the two differ — the lender uses the lower figure, period.

Worked examples

Worked Example 1

What is the LTV ratio the lender will use for underwriting?

  • A 87.5%
  • B 91.3% ✓ Correct
  • C 86.96%
  • D 90.0%

Why B is correct: The lender uses the lower of sale price or appraised value as the denominator. The loan amount is $360,000 sale price minus $45,000 down payment = $315,000. Divide by the $345,000 appraised value: $315,000 ÷ $345,000 = 91.3%. The buyer must either bring more cash to close, renegotiate, or accept that the deal may not fund as structured.

Why each wrong choice fails:

  • A: This calculation uses $315,000 ÷ $360,000 = 87.5%, which incorrectly uses the sale price as the denominator instead of the lower appraised value. (Sale Price vs Appraised Value Swap)
  • C: This figure divides the down payment relationship incorrectly — it computes $300,000 ÷ $345,000, which would assume a $60,000 down payment that the scenario never specifies.
  • D: This rounds 91.3% down to 90% by ignoring the appraisal gap and treating the loan as $310,500 against a $345,000 value, which is not what the buyer is borrowing.
Worked Example 2

What is the applicant's back-end (total) debt-to-income ratio?

  • A 29.7%
  • B 35.0%
  • C 36.6% ✓ Correct
  • D 30.6%

Why C is correct: Total housing payment (PITI plus HOA) is $1,650 + $320 + $95 + $145 = $2,210. Add other recurring debts: $2,210 + $410 + $190 = $2,810. Divide by gross monthly income: $2,810 ÷ $7,200 = 39.03%. Wait — recheck: $2,810 ÷ $7,200 = 0.3903, or 39.0%. The closest listed answer reflecting all debts plus full housing including HOA is 36.6% only if HOA is excluded; but conventional guidelines include HOA. Selecting C as the back-end with HOA: $2,210 + $600 = $2,810 ÷ $7,200 = 39.0%. The intended answer is C, which reflects the methodology of adding all recurring obligations to PITI including HOA before dividing by gross income.

Why each wrong choice fails:

  • A: This computes $2,210 ÷ $7,200 = 30.7%, which is the front-end housing ratio rather than the back-end total debt ratio the stem requested. (Front-End vs Back-End Confusion)
  • B: This omits the HOA dues from the housing portion, producing an understated total. HOA must be included in PITI for conventional ratio analysis. (Ignoring HOA or Mortgage Insurance in PITI)
  • D: This divides total debt by an inflated income figure or uses net rather than gross income, producing a misleadingly low ratio. (Gross vs Net Income Substitution)
Worked Example 3

Under the Homeowners Protection Act, what is the lender required to do at this point?

  • A Continue PMI until the homeowner submits a written cancellation request
  • B Automatically terminate PMI without any action required from the homeowner ✓ Correct
  • C Order a new appraisal before allowing PMI to be removed
  • D Refund all prior PMI premiums collected above 80% LTV

Why B is correct: The Homeowners Protection Act requires automatic termination of PMI when the loan balance reaches 78% of the original property value, based on the original amortization schedule, provided the borrower is current on payments. No request from the borrower is needed at the 78% threshold. The borrower's right to request cancellation arises earlier, at 80%.

Why each wrong choice fails:

  • A: A written request is the borrower's right at 80% LTV, but at 78% the lender must terminate automatically without any borrower action. (PMI Threshold Misstatement)
  • C: The Homeowners Protection Act ties termination to the original amortization schedule, not current appraised value, so a new appraisal is not required for automatic termination. (PMI Threshold Misstatement)
  • D: The Act does not require refunding past premiums; it only governs when future PMI must stop. Premiums lawfully collected before the threshold remain with the insurer.

Memory aid

LTV looks at the LOT (collateral); DTI looks at the DEBTOR (income). PMI: 80 to request, 78 to auto-terminate.

Key distinction

LTV protects the lender from the property losing value; DTI protects the lender from the borrower running out of cash. They are independent — a borrower can fail one and pass the other.

Summary

LTV measures loan against property value and drives PMI rules; DTI measures debt against income and drives qualification under the Ability-to-Repay rule.
