Three Metrics, Three Perspectives
When lenders evaluate a construction or investment property loan, they rarely look at just one leverage ratio. Most deals are sized using a combination of LTC, LTV, and LTARV. Each metric answers a different question about the deal's risk profile, and the most conservative result typically governs the maximum loan amount.
What is LTC (Loan-to-Cost)?
Total Project Cost = Land Acquisition + Construction or Renovation Budget + Soft Costs
LTC measures how much of the total project cost the lender is financing. If a builder is purchasing a lot for $100,000 and spending $300,000 on construction, the total project cost is $400,000. A loan of $360,000 would represent 90% LTC.
When LTC matters most: Ground-up construction loans, fix-and-flip loans, and any project where the borrower is creating value through new construction or substantial renovation. LTC is the primary sizing metric because it reflects the actual capital at risk relative to what has been spent.
What is LTV (Loan-to-Value)?
LTV measures the loan amount relative to the property's current market value. For a stabilized rental property appraised at $350,000, a loan of $262,500 would represent 75% LTV.
When LTV matters most: Purchases or refinances of stabilized, income-producing properties. DSCR rental loans, conventional mortgages, and portfolio term loans are primarily sized on LTV because the property is already in its finished, income-generating state.
What is LTARV (Loan-to-After-Repair-Value)?
LTARV (sometimes written as LTV-ARV or LTAV) measures the loan relative to what the property will be worth after construction or renovation is complete. This is a forward-looking metric based on a "subject-to-completion" appraisal.
When LTARV matters most: Construction and renovation loans where the finished value significantly exceeds the current value or cost basis. LTARV acts as a ceiling on leverage, ensuring the total loan does not exceed a safe percentage of the completed property's market value.
Side-by-Side Comparison
| Metric | Numerator | Denominator | Best Used For |
|---|---|---|---|
| LTC | Total Loan | Total Project Cost | Construction, fix-and-flip |
| LTV | Loan Amount | Current (As-Is) Value | Stabilized rentals, refinances |
| LTARV | Total Loan | After-Repair Value | Value-add, construction |
Worked Example: Same Deal, Three Metrics
Consider a builder purchasing a vacant lot and constructing a single-family home:
New Construction Project in Raleigh, NC
| Lot Purchase Price | $120,000 |
| Construction Budget | $280,000 |
| Total Project Cost | $400,000 |
| As-Is Lot Value (appraised) | $130,000 |
| After-Repair Value (ARV) | $550,000 |
| Loan Amount | $360,000 |
How Each Metric Sizes the Deal
| LTC | $360K / $400K = 90% |
| LTV (As-Is) | $360K / $130K = 277% |
| LTARV | $360K / $550K = 65.5% |
Notice how the same $360,000 loan looks very different depending on which metric you use. The LTV on the as-is lot value is 277%, which is why construction lenders do not use as-is LTV as a primary sizing tool for ground-up projects. Instead, they use LTC (90%) and LTARV (65.5%) together. The loan must satisfy both constraints.
If this lender's maximum parameters are 90% LTC and 75% LTARV, the deal works: 90% LTC (at the limit) and 65.5% LTARV (well within the 75% cap).
How Lenders Use All Three Together
In practice, construction and value-add lenders size loans using a "lesser of" approach. The maximum loan is the lowest amount produced by any applicable constraint. For example:
- 90% of Total Project Cost (LTC constraint) = $360,000
- 75% of ARV (LTARV constraint) = $412,500
- Maximum loan = $360,000 (the lesser of the two)
For stabilized rental property loans (DSCR, conventional), LTV is the primary metric because there is no construction or renovation component. The property's current appraised value is the relevant benchmark.
