One of the most common ways a deal that looks good on paper falls apart in practice is negative leverage. It's a concept most passive investors have never heard of, but understanding it is one of the clearest ways to identify risk in a private real estate investment before you commit capital.
What Negative Leverage Means
Negative leverage occurs when the levered cash on cash return is less than the unlevered cash on cash return. In plain terms: the debt is costing more than the asset is producing, which means leverage is hurting the investment rather than helping it.
One of the genuine advantages of commercial real estate is access to institutional debt. There is no other asset class where banks will lend 70% of the value at structured interest rates for years at a time. Used correctly, leverage amplifies returns. Using leverage and generating a return greater than the interest rate on the debt is positive leverage. But not all debt is created equal, and not all deals are structured to support the debt they carry.
How It Happens
Properties are valued by the capitalization rate, which is the property's net operating income divided by the purchase price. When a property's cap rate is lower than the interest rate on the senior debt, that's a red flag. The asset isn't generating enough income relative to its cost to support the leverage being placed on it.
When interest rates rise, this problem compounds. The cost of floating rate debt increases, cash flows tighten, and operators face a choice: push rents to cover the financing gap or come out of pocket to cover the shortfall. Pushing rents works until the market stops supporting it. Coming out of pocket works until the reserves run out.
Where It Gets Dangerous
The real problem surfaces at refinance. When a loan matures, the operator needs to replace it with new debt. If the property's value has softened, if cap rates have expanded, or if the lending environment has tightened, the new loan may not cover the existing one. The operator is then forced to bring cash to closing to bridge the gap. If they can't, the property defaults.
This is the chain of events behind most CRE distress that gets attributed to "market conditions." The market didn't cause the problem. Negative leverage and an overleveraged capital structure created a situation with no margin for error.
What to Ask Your Operator
As a passive investor, you won't underwrite the deal yourself. But there are two questions worth asking before committing capital:
What is the spread between the cap rate and the interest rate on the debt? A healthy spread provides a cushion. A thin or inverted spread is a warning sign.
What happens to the debt at refinance? What assumptions is the operator making about where rates and values will be at the time of the exit or refinance, and what does the deal look like if those assumptions are wrong?
The answers reveal how much risk is actually sitting inside a deal that might look attractive on a returns summary.
The Bottom Line
Leverage is a tool. Used with discipline and a conservative basis, it amplifies returns and creates wealth. Used carelessly, it turns a performing asset into a liability. Understanding the relationship between cap rates, interest rates, and debt structure is one of the most practical ways a passive investor can evaluate the real risk in any private CRE deal.
