Loan-to-Cost vs. Loan-to-Value
Executive Summary
Key Takeaways
- ✓ LTC sizes debt against total development cost; LTV sizes debt against the completed asset's appraised value, and the two metrics apply at different points in a development's life.
- ✓ LTC is the operative sizing metric during construction, when no stabilised asset value yet exists to size debt against.
- ✓ LTV becomes the operative sizing metric once the asset completes and is valued, typically on a term investment facility replacing the development facility.
- ✓ A given nominal leverage percentage can represent materially different actual risk depending on whether it is measured against cost (which can understate a well-located asset's eventual value) or against value (which can be volatile relative to the fixed cost actually incurred).
- ✓ Both metrics are frequently used together across a project's life, LTC governing the construction facility, LTV (or a coverage ratio) governing the term facility that follows it.
Overview¶
Loan-to-cost (LTC) and loan-to-value (LTV) are the two primary metrics lenders use to size real estate debt, distinguished by what the debt is measured against — see Loan-to-Cost Ratio for the full definition.
LTC expresses debt as a percentage of total development cost.
LTV expresses debt as a percentage of the asset's appraised market value.
Side-by-Side Comparison¶
| Dimension | Loan-to-Cost (LTC) | Loan-to-Value (LTV) |
|---|---|---|
| Denominator | Total development cost incurred | Appraised market value of the asset |
| Applicable stage | Construction / development phase | Post-completion / stabilised phase |
| Data requirement | Directly measurable as cost is incurred | Requires an independent valuation or appraisal |
| Typical facility | Development / construction facility | Term investment facility |
| Relationship to project outturn | Fixed to actual cost, independent of eventual value | Reflects eventual value, which can diverge materially from cost |
Decision Framework¶
LTC is the only metric reliably available during construction, since no stabilised, appraisable asset value yet exists, and should govern the development facility's sizing throughout that phase.
LTV (or a coverage-ratio-based metric) becomes the relevant sizing basis once the asset completes and stabilises, typically at the point a term investment facility replaces the development facility, and should govern that subsequent facility — see Build-to-Rent Model Structure for how this transition should be represented in the model.
Advantages¶
LTC advantages: directly measurable throughout construction with no dependency on a forward-looking valuation, and directly controls the equity requirement relative to actual spend.
LTV advantages: reflects the asset's actual realized value once complete, which can differ materially from its cost, giving a lender a value-based, rather than purely cost-based, view of collateral coverage.
Limitations¶
LTC limitations: says nothing about whether the completed asset will actually be worth more or less than its cost, so a conservative LTC does not guarantee a conservative eventual LTV.
LTV limitations: unavailable during construction (no stabilised value yet exists) and dependent on valuation assumptions and market conditions that can shift between initial appraisal and eventual disposal or refinancing.
Common Misconceptions¶
"A conservative LTC guarantees a conservative LTV." Not necessarily — a well-located or well-executed development can complete at a value materially above its cost, or underperform its projected value, meaning the two metrics can diverge in either direction once the asset is actually valued.
"LTV can replace LTC as the sizing metric during construction." No appraisable value exists before the asset nears completion, so LTC remains the only reliably measurable sizing basis throughout the construction phase itself.

Frequently Asked Questions
What is the core difference between LTC and LTV?
LTC expresses debt as a percentage of total development cost incurred to build the asset. LTV expresses debt as a percentage of the asset's appraised market value. The two use different denominators and are typically applied at different stages of a development's life.
Why is LTC used during construction rather than LTV?
Because no stabilised, appraisable asset value yet exists during construction, so cost, a figure that can be measured directly as it is incurred, is the operative and only reliably measurable basis for sizing debt at that stage.
When does LTV become the relevant metric?
Once the asset completes and can be independently valued, typically at the point a term investment facility replaces the development facility, reflecting the now-existing asset value and income stream rather than the fixed historical cost of construction.
Can a low LTC and a high LTV coexist on the same project?
Yes. A well-located or well-executed development can complete at a value materially above its cost, meaning a conservative LTC during construction can correspond to a comparatively higher LTV once the completed value is realized, and vice versa for a scheme that underperforms its projected value.
Should a lender rely on LTC or LTV alone?
Neither in isolation is generally sufficient. LTC is the only metric available during construction and constrains construction-phase risk; LTV (or a coverage ratio) becomes relevant once the asset stabilises and should govern the term facility that follows, so both metrics are typically applied together across the project's life rather than one replacing the other outright.

Loan-to-Cost Ratio
Loan-to-cost ratio (LTC) expresses senior debt as a percentage of total development cost, the primary sizing metric lenders apply to construction and development finance, where no stabilised income yet exists to size debt against a coverage ratio. It is distinct from loan-to-value (LTV), which sizes debt against completed asset value, and a development facility is typically governed by both metrics at different points in the project life.
Development Appraisal Model Structure
A development appraisal model differs structurally from a standing-asset model because it builds value forward from land and construction cost, through a phased sales or leasing velocity schedule, to a gross development value, with a residual land value calculated as an output rather than assumed as an input. This guide sets out the module architecture — assumptions, GDV build, cost and drawdown schedule, finance, and residual land value or returns output — that makes such a model auditable across the development lifecycle from feasibility through to completion.
Build-to-Rent Model Structure
A build-to-rent model spans two structurally distinct phases within one project — a development appraisal phase through practical completion, and a stabilised income-producing asset phase from lease-up onward — joined by an explicit transition point rather than a single continuous structure. This guide sets out how the lease-up curve should be modelled, how the transition to a term investment facility should be represented, and how the two phases hand off to each other.
Yield on Cost
Yield on cost expresses a development's projected stabilised net operating income as a percentage of its total development cost, a capital-efficiency metric distinct from market (exit) yield, which is measured against market value rather than cost. The spread between yield on cost and market exit yield is a standard development-viability test, since a positive spread indicates the completed asset's value should exceed its cost.
