Reference Field Card Breakdown for Every LTV Line Data Point
Use the below field card to map every component of a standard LTV underwriting line, regardless of which loan origination software your lender uses. The card applies to conventional, FHA, VA, and USDA residential loan files, as well as home equity loan and line of credit underwriting sheets from most national and regional lenders. Field order may shift slightly between platforms, but all core data points will appear in close proximity to the LTV line label, even when formatting is condensed for print.
| Field Position on LTV Line | Standard Label | Expected Data Format | Common Misread Trigger |
|---|---|---|---|
| Leftmost alphanumeric string | Condition ID | Alphanumeric code (e.g., COND-047-LTV), no attached dollar value | Readers often skip this code to pull numbers first, leading to matching LTV calculations to the wrong loan product on files with multiple liens or loan splits |
| First numeric percentage | Stated calculated primary LTV | 2-decimal percentage (e.g., 78.25%), rounded to the nearest 0.01% | Readers sometimes confuse this with combined LTV when multiple percentage figures are stacked on a single line |
| Second numeric percentage (if present) | Stated CLTV | 2-decimal percentage, inclusive of all subordinate liens on the collateral | Readers often treat this as primary LTV when verifying PMI removal eligibility, leading to incorrect threshold checks |
| First dollar figure adjacent to percentage values | Base eligible loan amount | Whole dollar value, aligned with figures on the most recent official loan disclosure | Readers sometimes add financed closing costs or upfront fees to this figure when recalculating, creating false mismatches |
| Second dollar figure adjacent to percentage values | Eligible collateral valuation amount | Whole dollar value, tied to a specific approved valuation source | Readers often use the highest available property value when cross-checking, rather than the source-specific value required for the calculation |
| Trailing free-text string | Required clearance action | Unstructured text outlining what must be submitted to sign off on the LTV line | Readers sometimes skip trailing text that specifies a required valuation update or lien check, leading to incomplete submissions |
Illustrative example: A line reading “COND-047-LTV 80.00% 95.00% $320,000 $400,000 Confirm no subordinate liens not disclosed on initial application” maps to a $320,000 primary loan, $60,000 subordinate HELOC, $400,000 collateral value, 80% primary LTV, and 95% CLTV, with a required action to verify no additional undisclosed debt secured by the property.
Embedded Value Labels That Signal Which Collateral Figure Drives Listed LTV
Not all LTV calculations use the same collateral base number, and short 2-3 character labels printed directly next to the collateral valuation figure tell you exactly which source the underwriter used to generate the listed LTV. The most common labels are: “APP” for appraised value from a state-licensed residential appraiser, used for most rate-term refinances and conventional purchase loans requiring a full appraisal; “PP” for contracted purchase price, used for purchase loans where the appraised value comes in higher than the contract price, as conforming loan rules require LTV to be calculated on the lower of the two values; “BPO” for broker price opinion, used for some home equity lines of credit and loss mitigation underwriting rather than a full appraisal; “AVM” for automated valuation model, used for preliminary pre-underwriting LTV checks and some low-LTV streamlined refinance products; and “ASR” for county tax assessed value, which almost never drives primary LTV calculations but may appear on adjacent property tax escrow lines mislabeled as LTV conditions.
If no label appears next to the collateral value figure, do not default to the most recent valuation in your file. For example, a lender may use a 6-month-old AVM for a preliminary LTV check even if a newer, higher appraised value is already in the file, because the AVM is the approved valuation source for that specific pre-clearance step. Using the wrong collateral figure can lead you to incorrectly assume the underwriter made a math error, when in fact the calculation is tied to a required source per investor rules.
Never Guess List Items for Ambiguous LTV Line Condition Text
When LTV line text is vague or missing key labels, never make assumptions to speed up clearance, as these are the most common triggers for repeated condition rejections and closing delays. Use this mandatory do-not-guess checklist for all ambiguous lines:
- [ ] Do not guess which lien position the listed LTV applies to if the line does not explicitly label primary vs. subordinate lien status: a 100% LTV line for a second mortgage carries vastly different requirements than 100% LTV on a first mortgage.
- [ ] Do not guess that a whole-number rounded LTV (e.g., 80%) is a final calculated figure; rounded values almost always indicate a preliminary placeholder that will be updated once final collateral value is confirmed.
- [ ] Do not guess that financed mortgage insurance premiums or upfront guarantee fees are excluded from the loan amount used for LTV: some conventional and government loan programs include these financed charges in LTV calculations, while others exclude them.
- [ ] Do not guess that LTV for a construction-to-perm loan uses the finished home value; some interim draw checks use as-is lot value for LTV calculations.
- [ ] Do not guess that a recent home purchase price is the valid collateral value for a cash-out refinance within 12 months of purchase; most lenders require a new appraisal and may use the lower of purchase price or new appraisal per delayed financing rules.
- [ ] Do not guess that LTV thresholds for automatic PMI removal match the initial loan LTV; federal PMI rules use the original property value unless a new appraisal is formally approved per investor requirements.
- [ ] Do not guess that a listed LTV on a conditional approval applies to the final loan amount if you have requested a principal reduction after initial underwriting; LTV lines are not auto-updated for post-submission loan changes.
Any ambiguous line item that falls on this list requires written clarification from the assigned underwriter before you submit supporting documents.
File Validation Steps to Confirm Stated LTV Matches Source Documentation
Once you have mapped the LTV line fields and identified the required collateral source, complete these sequential validation steps to confirm the listed LTV is accurate before preparing clearance materials. First, pull the exact, fully executed source document for the labeled valuation: for “APP” labels, pull the full appraisal with the appraiser’s license number, signature, and effective date; for “PP” labels, pull the fully executed purchase contract with all buyer, seller, and agent signatures; for “BPO” or “AVM” labels, pull the dated valuation report generated directly from the lender’s approved vendor portal, rather than a third-party estimate you pulled independently. Second, pull the most recent loan amount figure from the official loan estimate or closing disclosure, separating line items for financed closing costs, upfront guarantee fees, or mortgage insurance premiums unless the relevant loan program guidelines explicitly state those charges are included in LTV calculations. Third, run the core LTV calculation to two decimal places: (eligible loan principal for LTV / eligible collateral value) * 100. Fourth, pull the current title report schedule of liens to list all open mortgages, HELOCs, judgment liens, or tax liens secured by the property, to cross-check any listed CLTV figure. Fifth, compare your calculated LTV and CLTV directly to the figures listed on the underwriting condition line, noting any gaps larger than 0.01%.
Illustrative example: If the condition line lists 78.00% LTV and your manual calculation returns 78.32%, the figures do not match, and you will need to trace the source of the gap (e.g., an unapplied principal reduction, an outdated collateral value, or an included subordinate lien you missed) before submitting clearance documents. If the discrepancy is 0.25% or larger, do not submit documentation until you resolve the gap, as differences of that size often cross key thresholds for mortgage insurance removal, loan pricing adjustments, or program eligibility. FinanceFortifyHub’s free LTV input tracking worksheet can help you log each source and calculation step to reduce arithmetic errors, but always cross-check your inputs against the lender’s published investor guidelines for your specific loan product.
Condition Clearance Documentation Required to Finalize LTV Line Sign-Off
Underwriters require full, traceable documentation to sign off on an LTV condition, so prepare the following standardized packet to avoid repeated requests for additional information. First, include a one-page written reconciliation sheet that lists every input used for your LTV check: source of collateral value, document ID for that valuation, exact loan principal figure used, document ID for the loan amount source, list of all subordinate liens included in CLTV with their current payoff amounts and source documents, and your final calculated LTV/CLTV to two decimal places. Second, attach full unredacted copies of all source documents cited on the reconciliation sheet; partial page submissions will be rejected, as underwriters must confirm document authenticity and eligibility, not just the numeric inputs for LTV. For example, submitting only the value page of an appraisal will not be accepted, because underwriters must confirm the appraisal meets all property eligibility requirements, not just the number used for LTV. If submitting updated valuation information to correct a listed LTV, include a short cover note that clearly states the updated value, source document, and corrected LTV calculation, so the underwriter does not have to search attachments for relevant updates. If the condition asks for confirmation of no new liens, include both an updated title report run within 10 days of submission and a signed borrower attestation that no new credit accounts secured by the property have been opened since initial application, as title reports can have a short lag in recording new liens.
Pull your most recent underwriting condition sheet right now and highlight every LTV line to cross-reference against the field card and do-not-guess list before gathering any supporting clearance documents.
