Loan-to-value (LTV) compares your loan to what the property is worth. Loan-to-cost (LTC) compares your loan to what the project costs you. On a purchase of a stabilized building, LTV usually drives the loan size. On construction, a major renovation or a ground-up build, lenders look at both and typically lend against whichever gives the smaller number.
That last point is where borrowers get surprised. A budget that looks well funded on cost can still fall short on value, and the reverse is also true. This guide shows the math, a worked example for each case, and the questions to ask before you sign a term sheet.
TL;DR
- LTV = loan ÷ appraised value. LTC = loan ÷ total project cost. Same loan, two different denominators.
- LTV is the standard yardstick for existing properties. LTC shows up on construction, development and value-add deals.
- On a project, the lender will often size the loan to the lower of its LTC cap and its LTV cap, so the tighter limit sets your loan.
- The percentage matters less than the denominator: ask which appraisal value, which costs and which liens the lender counts.
- Higher leverage raises potential equity returns and widens the downside. Plan reserves for overruns and delays.

What LTV measures
LTV answers one question: how big is the loan relative to the collateral securing it? Federal real estate lending standards define it at origination as the credit extended divided by the value of the property securing or being improved, with senior liens counted. The formula is:
LTV = loan amount ÷ collateral value
A $1,500,000 loan against a building appraised at $2,000,000 is 75% LTV. The value is the lender's appraised figure, not your purchase price and not your own estimate. If the appraisal comes in below the contract price, the loan shrinks to match.
On a project that isn't finished, lenders may quote LTV against the value the property is expected to have once the work is done. You'll hear this called as-completed or after-repair value. Always ask which value is meant, because "as-is" and "as-completed" can differ by a wide margin.
What LTC measures
LTC answers a different question: how much of the total project cost is the lender financing? Massachusetts' commercial real estate training material describes loan-to-cost as a technique used for new construction, with financing based on a percentage of estimated construction cost. The formula:
LTC = loan amount ÷ total project cost
Total cost normally means land or purchase price plus hard costs (labor and materials) plus soft costs such as permits, design and financing costs. Exactly which items count varies by lender, so get the eligible-cost list in writing.
LTC protects the lender against a different risk than LTV does. It forces you to put real equity into the deal, so you share the pain if the budget runs over.
LTC vs. LTV at a glance
| LTV (loan-to-value) | LTC (loan-to-cost) | |
|---|---|---|
| Denominator | Appraised value (as-is or as-completed) | Total project cost |
| Typical use | Purchases and refinances of existing property | Construction, development, heavy rehab |
| Risk it controls | Collateral shortfall if the property is sold | Cost overruns and thin borrower equity |
| Who sets the number | An appraiser | Your budget, checked by the lender |
| Moves when | Market value or income changes | Costs rise or scope changes |
Worked examples: which ratio caps your loan
The caps below are hypothetical, chosen to make the math clear. Real lender limits vary by lender, property type and borrower.
Assume a lender allows up to 80% LTC and up to 75% LTV.
Example 1: cost is the limit
You buy land for $300,000 and budget $700,000 for construction. Total cost is $1,000,000. The appraiser says the finished building will be worth $1,250,000.
- 80% of cost: $800,000
- 75% of value: $937,500
- Loan: $800,000, because the LTC cap is the lower number
- You contribute $200,000 of equity
Example 2: value is the limit
Same $1,000,000 cost, but the appraisal comes in at $1,000,000.
- 80% of cost: $800,000
- 75% of value: $750,000
- Loan: $750,000, because the LTV cap is the lower number
- You contribute $250,000 of equity, $50,000 more than you planned
The project did not change. The appraisal did. That is why borrowers who only calculate LTC are sometimes caught short at closing. Federal supervisory material on SBA 504 lending describes the same trap: financing can look acceptable on cost yet fail the valuation test. If appraised value falls below the combined financing, the lender may require more equity, cut the loan or ask for additional collateral.
What the regulators say about the numbers
You will see percentages quoted everywhere. Here is what the primary sources actually say, and what they don't.
Interagency guidelines set example supervisory LTV limits for banks: 65% for raw land, 75% for land development, 80% for multifamily and other nonresidential construction, 85% for one-to-four-family residential construction and 85% for improved property. These are ceilings for bank policy, not offers. Many lenders set tighter internal limits, and they are not guarantees that you'll get that much.
A separate rule defines a narrow class of qualifying commercial real estate loans. For that category, the stated thresholds include LTV at or below 65% with combined LTV at or below 70%, among other conditions. That is a regulatory definition for a defined category, not a market-wide quote. If you want to understand why 65% shows up so often and how borrowers bring the ratio down, we cover it in why 65% often caps commercial loan LTV.
On the cost side, FDIC guidance for tract development says advances should not exceed actual development or construction costs, and that the borrower should maintain appropriate hard equity. In other words, lenders assess project-cost support and eventual collateral value together. They don't pick one.
Why the denominator matters more than the percentage
Two lenders can both advertise "75% LTV" and fund very different loans. The difference is in what goes into the math.
Federal appraisal guidance notes that collateral value rests on an appraisal, and the calculation can require attention to other collateral, liens, discounts and the loan structure. For a development project, appraisals can reflect deductions for holding and marketing costs, which lowers the value the lender counts.
Before you compare offers, ask each lender:
- Is value as-is or as-completed?
- Which appraisal will be used, and who orders it?
- Are existing liens or other debt included in the ratio?
- Which costs count toward total cost? Are soft costs, interest reserves and contingency eligible?
- Is the loan sized to the lower of LTC and LTV, or to one only?
- Does your own cash, or the land you already own, count toward equity, and at what value?
If appraisal quality is your concern, look at how local details can pull a valuation down. This Virginia guide to avoiding low appraisals covers residential preparation, but it shows how condition and comparable sales affect the number. For commercial properties, our commercial appraisal cost checklist walks through budgeting for the report.
Draws, reporting and the cost of an LTC loan
A high LTC does not mean the lender hands you the money on day one. FDIC guidance describes lenders controlling advances through a borrowing-base certificate: frequent, usually monthly, borrower-prepared reports, eligibility rules, advance rates by collateral type and on-site verification. Budget time and fees for that reporting and for inspections.
For phased projects, the same guidance says LTV should be recalculated when collateral is released or substituted. That can change your borrowing capacity mid-project even though the original commitment stands.

SBA 504 and other structured deals
SBA programs change how the ratios look. In a 504 transaction, the bank's first mortgage and the Certified Development Company (CDC) portion sit together. The OCC states that the bank's exposure can potentially exceed an applicable supervisory LTV limit because of the program structure and CDC takeout commitments, and that any exception must be tracked and reported. That is specific to SBA 504 and is not a sign that every SBA loan allows high leverage.
Two practical takeaways. First, ask how both the bank loan and the CDC portion are measured against value. Second, expect an appraisal: SBA requires a state-licensed or certified appraiser for loans over $500,000 secured by commercial real property (notice dated 2019, so confirm current rules with your lender). Buyers using SBA money for an acquisition should also read about the 10% equity injection and business acquisition financing.
Leverage cuts both ways
A higher LTV or LTC means you put in less cash. That can lift your return on equity, and it can sink it. MIT's real estate finance course uses an example of a $10 million property with $6 million of debt, or 60% LTV and $4 million of equity. In that illustration, equity total returns range from -14.5% to 40.5%, against -1% to 21% for the unlevered property. It is a 2006 teaching example, not a forecast, but the lesson holds.
The question to ask is not which ratio is higher. It is whether the property's cash flow and your reserves can survive cost overruns, delays, vacancies or a lower valuation. For a plain-language view of how borrowers think about downside on short-term real estate debt, this hard money lending guide is a useful second read.
Lenders also don't treat any single ratio as a pass or fail. The OCC's commercial real estate handbook treats LTV as one part of broader underwriting, alongside repayment capacity, borrower strength, project feasibility, collateral quality and construction controls. A deal with strong cash flow can win better terms than the same ratio on a weaker one. Debt service coverage matters too, which is why our guide to interest-only commercial loans and commercial mortgage rates belong in the same research session.
How to lower the equity you need to bring
- Raise the denominator honestly. For LTV, strengthen the appraisal package: rent rolls, leases, comparable sales, a clear scope of improvements.
- Tighten the budget. For LTC, a realistic budget with a contingency line is easier to finance than an optimistic one the lender must haircut.
- Add collateral. Other assets can reduce the exposure the lender counts. See what small businesses can pledge as collateral.
- Use owned land as equity. Many lenders credit land you already own, but at which value, cost or appraisal, is a question for each one.
- Compare lender types. Banks, SBA lenders and private lenders set different caps. Comparing several real offers shows you the spread.
Our perspective: ask for the lower number first
In our work with owners and investors, the most common mistake is planning around the higher of the two ratios. A borrower sees an 85% LTC quote, assumes they need 15% equity, and then learns the appraisal supports a lower LTV. We would rather you plan on the tighter limit from the start and treat anything above it as a bonus.
We built Formosity Funding around that idea. You can pre-qualify with no credit impact, see real offers from a nationwide lender network, and have a funding specialist walk you through how each lender is sizing the loan. Lenders pay us when a loan closes, so we only do well when the deal fits you and funds. That's a reason to put the structure on the table early: the cost basis, the value assumption and the equity you'll bring.

FAQ
Are LTC and LTV the same thing?
No. Both compare a loan to something, but LTV divides by appraised value and LTC divides by total project cost. They only match when value equals cost. On construction and value-add deals they usually differ, and lenders often use both.
What does 80% LTC mean?
The lender will finance up to 80% of total project cost, and you fund the other 20%. On a $1,000,000 project that is $800,000 of debt and $200,000 of equity. The loan can still be smaller if an LTV cap produces a lower figure.
Which is better for the borrower, LTC or LTV?
Neither is better by itself. The better one is whichever produces the larger loan on your deal, but lenders typically apply the tighter of the two. Compare the actual loan amount and equity required from each offer.
Do LTC and LTV apply to SBA loans?
Yes, in different ways. SBA lenders appraise commercial real estate, and 504 structures combine a bank loan with a CDC portion, so ask how both are measured against value and cost. Terms depend on the program and lender, so confirm the details before you commit.
