In commercial real estate lending, two ratios come up in virtually every financing conversation: loan-to-cost (LTC) and loan-to-value (LTV). Both measure how much a lender is willing to finance relative to some baseline, but that baseline is different in each case, and so is the context in which each metric applies.
Confusing the two is easy, and surprisingly common. Using the wrong framework when approaching a lender, or failing to understand how each metric constrains a loan, can lead to misaligned expectations and avoidable delays. This post explains what each ratio measures, when lenders use them, and how understanding both can help developers structure their financing more effectively.
Loan-to-Cost: The Construction Lender’s Benchmark
Loan-to-cost (LTC) measures the loan amount as a percentage of the total cost to develop a project. The denominator, total project cost, typically includes land acquisition, hard construction costs (labor and materials), and soft costs (architecture, engineering, permits, financing fees, and developer overhead). The formula is simple: LTC = Loan Amount ÷ Total Project Cost.
LTC is the primary ratio construction lenders use when underwriting ground-up development. The reason is practical: a property that doesn’t yet exist can’t be appraised in the traditional sense. Since the completed building has no current value to measure against, lenders anchor the loan to the cost of building it instead.
A project with a total cost of $10 million and a $7.5 million construction loan has an LTC of 75%. Where the ceiling sits depends heavily on the capital source. Banks, still the most rate-competitive construction lenders, generally top out between 55% and 65% LTC in the current environment. Debt funds and other private lenders stretch to 75%, and in select cases 80% to 85%, at meaningfully wider pricing The LTC ceiling effectively defines how much equity the developer must contribute: a lower LTC limit means more equity is required.
One more nuance that surfaces on nearly every deal: what counts as cost. A developer who bought land years ago at $2 million that now appraises at $6 million will push for market-value credit in the cost basis; most lenders will credit actual cost, sometimes with a negotiated bump for entitlement work or hold period. Whether the lender gives credit for that imputed equity can swing the effective LTC, and the cash equity requirement, by millions.
Loan-to-Value: The Permanent Lender’s Starting Point
Loan-to-value (LTV) measures the loan amount as a percentage of the property’s appraised market value. The formula: LTV = Loan Amount ÷ Appraised Value. Unlike LTC, LTV relies on a third-party appraisal to establish the denominator.
LTV is the standard metric for acquisition financing and permanent loans on existing, income-producing properties. When a property is already built, stabilized, and generating cash flow, an appraiser can assess its market value by analyzing comparable sales and income performance. LTV then determines how much of that value a lender will finance.
Most conventional commercial real estate lenders cap permanent loan LTVs between 65% and 75%, though this varies by property type and lender appetite. Agency lenders, Fannie Mae and Freddie Mac, may go slightly higher on qualifying multifamily assets. The LTV constraint protects lenders by ensuring there is a meaningful equity cushion between the loan balance and the property’s value.
How They Interact on a Development Deal
Here’s where the distinction gets practically important: on a construction project, lenders often apply both ratios simultaneously, and the more conservative constraint wins.
Consider a project with a total cost of $15 million and an estimated completed value of $20 million. A lender with a maximum LTC of 75% would allow a loan of up to $11.25 million. The same lender with a maximum LTV of 65% (applied to the as-completed appraised value) would allow up to $13 million. In this case, LTC is the binding constraint: even though the as-completed LTV leaves room for a larger loan, the lender won’t exceed its cost-based limit.
The reverse can also occur. If construction costs are lean relative to projected value, say, a developer is adding significant value through entitlements or design, the LTV ceiling may bite first. Lenders are aware of this and will apply whichever ratio produces the lower loan amount.
| Loan-to-Cost (LTC) | Loan-to-Value (LTV) | |
| Formula | Loan Amount ÷ Total Project Cost | Loan Amount ÷ Appraised Value |
| Best used for | Ground-up development and construction loans | Acquisitions and permanent financing of existing properties |
| Denominator source | Developer’s budget (land + hard + soft costs) | Third-party appraisal |
| Typical max ratio | Banks: 55–65%. Debt funds: up to 80–85% | 65–75% (standard for commercial property) |
| Key risk for lender | Cost overruns inflate denominator, reducing effective coverage | Appraisal may not reflect true market value at time of sale or refi |
Why LTV Gets Complicated During Construction
Applying LTV to a project that doesn’t yet exist requires an appraiser to estimate the property’s value as if it were complete and stabilized, sometimes called an as-completed or as-stabilized appraisal. While useful, this approach introduces a layer of uncertainty that construction lenders treat with appropriate skepticism.
Market conditions can change meaningfully over a two- or three-year construction timeline. Rental rates, cap rates, and comparable sales data can all shift, making the original appraisal less reliable by the time the project delivers. This is precisely why LTC, which anchors to hard budget figures rather than projected market conditions, tends to be the more conservative and reliable tool for construction lenders.
When the project completes and moves to permanent financing, the dynamic reverses. At that stage, the property can be appraised based on actual performance, and LTV becomes the primary driver of the loan amount the permanent lender will offer.
Putting It Together
Understanding the difference between LTC and LTV isn’t just a technical exercise; it’s a practical tool for structuring deals and managing lender conversations. Knowing which constraint is likely to bind on a given project helps developers right-size their equity contributions from the start, avoid surprises during underwriting, and have more productive conversations with both construction and permanent lenders.
As a general rule: think LTC during the construction phase, LTV once the asset is stabilized. And remember that leverage ratios are only half of loan sizing. Lenders ultimately fund to the most conservative of LTC, LTV, DSCR, and debt yield, so the leverage a deal can carry is often set by cash flow, not cost or value.
