What Is Positive Leverage in Real Estate?

Key Takeaways

• Positive leverage exists when the cap rate exceeds the loan constant, so borrowed money earns more than its annual cost and the equity yield rises.
• The loan constant includes principal as well as interest, so an amortizing loan can produce negative leverage even when its interest rate sits below the cap rate.
• With the average single-tenant net lease cap rate at 6.82% in Q2 2026 and the 10-year Treasury at 5.18% in September, typical amortizing loans are negative leverage.
• Negative leverage lowers current cash yield and magnifies losses, which is why many net lease buyers use low loan-to-value debt or pay all cash.
• A loan can pass a lender's coverage test and still be negative leverage, because coverage and leverage answer different questions.

What positive leverage means

Positive leverage means the property earns a higher yield on its full price than the loan costs as a share of its balance. The property yield is the cap rate and the cost of the debt is the loan constant. When the cap rate is higher, the spread between the two accrues to the equity, and the cash-on-cash return rises above the cap rate.

The cap rate is net operating income divided by price. The loan constant, sometimes called the mortgage constant, is the full annual payment of principal and interest divided by the original loan amount. Both are yields on dollars: one on dollars invested in the building, the other on dollars owed to the lender. Comparing them tells you whether each borrowed dollar pays for itself out of the property's income.

The relationship can be written as one equation. Cash-on-cash return equals the cap rate plus the spread (cap rate minus loan constant) multiplied by the ratio of debt to equity. If the spread is positive, more debt pushes the equity yield up. If the spread is negative, more debt pushes it down, and the more you borrow, the further it falls.

Why you compare the loan constant, not the interest rate

The interest rate understates the cash cost of an amortizing loan. Each monthly payment also repays principal, and that principal comes out of the same net operating income. On a 30-year schedule a 6.50% loan carries a loan constant of about 7.585%; on a 25-year schedule the constant rises to about 8.102%.

Only on an interest-only loan does the constant equal the interest rate. That is why a pro forma can show positive leverage during an interest-only period and negative leverage once amortization begins, with no change in the property at all. Principal repayment is not lost money: it builds equity that is recovered at sale or refinance. But it is cash that does not reach investors while the loan is outstanding, so it belongs in any comparison of current yield.

• Loan constant, interest-only: equal to the interest rate.
• Loan constant, amortizing: 12 x monthly payment / loan amount, always higher than the rate.
• Shorter amortization: higher constant, and less room for positive leverage.

Worked example: one property, seven ways to finance it

The same property can be positive, neutral or negative leverage depending only on the loan terms. The hypothetical example below uses a $2,000,000 single-tenant net lease property bought at a 6.80% cap rate, so net operating income is $136,000. Each loan is $1,200,000 (60% loan-to-value), leaving $800,000 of equity.

Closing costs, fees and reserves are ignored to isolate the effect of the debt.

Hypothetical example: $2,000,000 property, $136,000 NOI, 6.80% cap rate, $1,200,000 loan, $800,000 equity

Loan terms (hypothetical)	Loan constant	Annual debt service	Cash flow after debt	Cash-on-cash	DSCR	Leverage
All cash, no loan	n/a	$0	$136,000	6.80%	n/a	None
4.50%, 30-year amortization	6.080%	$72,963	$63,037	7.88%	1.86x	Positive
5.00%, 30-year amortization	6.442%	$77,302	$58,698	7.34%	1.76x	Positive
5.50%, 30-year amortization	6.813%	$81,762	$54,238	6.78%	1.66x	Neutral to slightly negative
6.50%, 30-year amortization	7.585%	$91,018	$44,982	5.62%	1.49x	Negative
7.25%, interest-only	7.250%	$87,000	$49,000	6.13%	1.56x	Negative
7.25%, 30-year amortization	8.186%	$98,233	$37,767	4.72%	1.38x	Negative
7.25%, 25-year amortization	8.674%	$104,084	$31,916	3.99%	1.31x	Negative

Three things stand out in this hypothetical. First, the 5.50% loan has an interest rate 130 basis points below the cap rate, yet it adds nothing to the cash yield, because its 6.813% constant is slightly above 6.80%. Second, on a 30-year schedule the interest rate has to fall to about 5.48% before the constant drops below a 6.80% cap rate; on a 25-year schedule it has to fall to about 4.69%. Third, both amortizing 7.25% loans clear a 1.30x coverage test while cutting the cash-on-cash return by 2.08 to 2.81 percentage points.

Why positive leverage is hard to find in 2026

Positive leverage is scarce in single-tenant net lease today because cap rates sit close to, or below, what lenders charge. The Boulder Group reported an average single-tenant net lease cap rate of 6.82% for Q2 2026 (published July 7, 2026). The 10-year Treasury yield was 5.18% on September 24, 2026, according to the Federal Reserve's H.15 release.

CBRE reported an average mortgage interest rate of 5.7% on the non-agency commercial loans it closed in Q2 2026, with spreads averaging 204 basis points (released August 3, 2026). At 5.7% on a 30-year amortization the loan constant is about 6.97%, and on a 25-year amortization about 7.51%. Both are above a 6.82% cap rate, so the average loan on an average-priced net lease property was mildly negative leverage even before any change in rates after June.

The sectors that come closest to neutral are the ones already priced for more risk. Boulder's Q2 2026 averages were 7.85% for drug stores and 7.49% for dollar stores, against 5.85% for corporate quick-service restaurants. A higher cap rate makes the leverage math look better precisely because the market sees more risk in the rent. Chasing positive leverage by buying higher cap rates can mean trading a financing problem for a credit problem.

What negative leverage means for investors

Negative leverage means debt lowers the current cash yield on equity while still adding the risks of debt: a payment that must be made whether or not the tenant pays, a maturity date that may need refinancing, and losses magnified in a downturn.

It does not automatically make an investment unattractive, but the case for the loan then rests on something other than current income.

Investors who accept negative leverage are usually relying on one or more of these:

• Rent growth. Scheduled escalations raise net operating income over time while fixed-rate debt service stays flat, so a deal that starts negative can turn positive in later years.
• Diversification. Borrowing lets the same equity own more properties or more tenants, trading some yield for less concentration.
• Amortization. Principal repayment builds equity even though it is not distributed.
• Tax treatment. Interest is generally deductible, which changes after-tax results. Confirm how this applies to you with your own tax advisor.
• Refinancing at lower rates. This is a forecast, not a feature of the deal, and it should be treated that way.

Many net lease buyers respond by paying all cash or borrowing at low loan-to-value. The Boulder Group's Q2 2026 report noted private capital and 1031 exchange buyers competing for premium net lease assets. An all-cash buyer earns the cap rate as its cash yield and carries no refinancing or maturity risk. A low loan-to-value loan (for example, a hypothetical 35% to 45% of value) limits how much a negative spread can drag the yield down while keeping some liquidity in reserve.

How positive leverage relates to DSCR, debt yield and cash-on-cash

Positive leverage asks whether debt helps the equity. Debt service coverage and debt yield ask whether the income protects the lender. They are linked but not interchangeable, and a loan can satisfy the lender's tests while hurting the investor's cash yield.

• DSCR equals the cap rate divided by (loan-to-value x loan constant). In the hypothetical above, 6.80% / (0.60 x 8.186%) is about 1.38x, a comfortable coverage ratio on a negative leverage loan.
• Debt yield equals the cap rate divided by loan-to-value. At 60% of value, a 6.80% cap rate gives a debt yield of about 11.33%, whatever the interest rate.
• Cash-on-cash return is where leverage shows up. It rises above the cap rate only when the spread is positive.
• IRR can still rise with negative leverage if the property appreciates, because the gain accrues to a smaller equity base. That is the same magnification working in both directions.

Common mistakes

Most leverage errors come from comparing the wrong numbers or stopping the analysis too early. The mistakes below turn a deal that looks like positive leverage on a summary page into negative leverage once the actual loan terms, the real net operating income and the full loan term are modeled.

• Comparing the cap rate to the interest rate. The payment includes principal. Use the constant at the amortization the lender will actually offer.
• Using the offering memorandum cap rate. A broker's cap rate is often based on scheduled rent. Landlord costs under a double-net lease, such as roof and structure, reduce the real yield.
• Stopping at the interest-only period. Underwrite the first amortizing year, not only the teaser years.
• Ignoring fees. Origination fees, lender legal costs and required reserves raise the effective cost of debt and lower equity yield.
• Mismatching loan and lease term. A loan maturing after the lease expires has to be refinanced against a building that may be vacant.

Frequently Asked Questions

Q: What is the difference between positive and negative leverage?

A: Positive leverage occurs when the cap rate is higher than the loan constant, so borrowing raises the cash-on-cash return on equity. Negative leverage occurs when the loan constant is higher than the cap rate, so borrowing lowers the cash yield compared with paying all cash.

Q: How do you calculate the loan constant?

A: Divide the total annual debt payment, principal plus interest, by the loan amount. For an interest-only loan the constant equals the interest rate. For an amortizing loan it is higher, and it rises as the amortization period gets shorter.

Q: Can a loan be negative leverage if the interest rate is below the cap rate?

A: Yes. In a hypothetical 6.80% cap rate purchase, a 5.50% loan on a 30-year schedule has a loan constant of about 6.81%, so it adds nothing to cash yield. The principal portion of the payment is what closes the gap.

Q: Is negative leverage always a bad investment?

A: Not always. It lowers current cash yield and adds risk, but investors may accept it for diversification, scheduled rent growth that raises income over time, or tax reasons. The case should rest on something specific rather than an assumed future refinance at lower rates.

Q: Why do some net lease investors pay all cash?

A: When loan constants exceed cap rates, debt reduces cash yield instead of increasing it. Paying all cash, or borrowing at a low loan-to-value, keeps the cash yield at or near the cap rate and removes refinancing and maturity risk.
