The Short Version
The claim's own numbers contradict its conclusions. Standard formulas applied to the stated inputs ($24,000 rent minus $5,000 expenses = $19,000 NOI) yield a 7.6% cap rate — close to but not 7.2% — and a cash-on-cash return of roughly 7.7%, far below the claimed 10–13%. Reaching 10–13% would require materially different inputs such as a much smaller down payment or significantly higher rent. The cash-on-cash figure is substantially overstated and could mislead prospective investors.
