An investor purchased a rental property for $500,000. Closing costs amounted to $15,000, and they spent an additional $35,000 on renovations before renting it out. If the property generates an annual net operating income (NOI) of $45,000, what is the cash-on-cash return?

Correct answer: A. 8.57%

Cash-on-cash return is calculated as annual before-tax cash flow divided by the total cash invested. Total cash invested = Purchase Price + Closing Costs + Renovation Costs. Annual before-tax cash flow is typically the NOI, assuming no debt service is mentioned or to be calculated. Total cash invested = $500,000 + $15,000 + $35,000 = $550,000. Cash-on-cash return = $45,000 (NOI) / $550,000 = 0.081818... or 8.18%. The provided answer 'A' is 8.57%. This implies a different total cash invested. If Cash-on-cash = $45,000 / X = 0.0857, then X = $45,000 / 0.0857 = $525,087. What if the question implies only cash down payment? If the investor financed a portion, say 80%, then their cash down payment would be 20% of $500,000 = $100,000. Total cash invested = $100,000 + $15,000 + $35,000 = $150,000. Then $45,000 / $150,000 = 0.30 or 30%. This doesn't match. Let's re-read the definition of Cash-on-Cash Return. It's Annual Before-Tax Cash Flow / Total Cash Invested. If 'annual net operating income (NOI) of $45,000' is given, and no debt service is mentioned, then NOI is usually taken as the cash flow for this calculation. Total cash invested is the actual out-of-pocket money. If the property was purchased for $500,000, and no financing is mentioned, it's assumed to be an all-cash purchase for the *equity* part. If the investor paid cash for the entire $500,000, then total cash invested = $500,000 (purchase) + $15,000 (closing) + $35,000 (renos) = $550,000. Cash-on-Cash = $45,000 / $550,000 = 8.18%. This is option C. Let's check if there's an interpretation that leads to 8.57% (Option A). If the total cash invested was $525,000, then $45,000 / $525,000 = 0.0857. How could we get $525,000? If closing costs were $10,000 and renovations $15,000 (total $25,000) added to $500,000. But the question states $15,000 and $35,000. What if NOI is not the cash flow? Cash-on-cash return explicitly uses *before-tax cash flow*, which is NOI *minus annual debt service*. Since no debt service is provided, we typically assume NOI *is* the cash flow for the purpose of this calculation, OR that the property was purchased all cash (no debt service). If it was an all-cash purchase, then NOI = cash flow. Let's assume the question intends for 'total cash invested' to be the purchase price plus the costs, which is $550,000. Then the answer is 8.18%. If the answer key states A (8.57%), this suggests a total cash invested of ~$525,087. The only way to get this from $500,000 purchase price is if closing costs + renovations were $25,087. Given the exact numbers, it's hard to get to 8.57%. Let's assume there's a slight rounding in the question or options. However, based on the calculation with the given figures: $500,000 (purchase) + $15,000 (closing) + $35,000 (renovations) = $550,000 (total cash invested). Annual before-tax cash flow (NOI) = $45,000. Cash-on-cash return = $45,000 / $550,000 = 0.081818... = 8.18%. Therefore, option C is the correct answer based on the provided numbers. I will adjust the answer to C. If option A was intended, the numbers in the question are inconsistent.
