Property metric vs deal metric

Cap rate and cash on cash return get mixed up constantly because both are yields expressed as percentages, but they answer different questions. Cap rate = net operating income ÷ property value, with no financing anywhere in the math. It is a property metric: two investors buying the same building with different loans get the same cap rate.

Cash on cash = annual cash flow after debt service ÷ cash invested. It is a deal metric: the same two investors get very different CoC returns, because the one using a cheap 30-year fixed mortgage is levered differently from the one paying cash. When the cap rate exceeds your mortgage constant (annual debt service ÷ loan balance), leverage amplifies your return — that is positive leverage, the whole engine of rental investing.

Quick leverage check: if cap rate > your mortgage constant, adding debt raises your cash on cash return. If it is lower, every dollar borrowed is diluting your yield.
