Key Takeaways
- Cap Rate (7.01%) is an unlevered pricing metric—it ignores financing and is useful for comparing properties.
- Cash-on-Cash (11.1%) is a levered metric measuring annual pre-tax cash flow as a percentage of equity invested.
- DSCR (1.46x) is the lender's safety metric—most commercial lenders require a minimum of 1.20-1.25x.
- The 20-unit example produces BTCF of $44,220, providing a 0.21x DSCR cushion above the typical 1.25x minimum.
Once you have calculated NOI, the next step is to derive the return and safety metrics that drive acquisition decisions. This lesson walks through the complete workflow for calculating Cap Rate, Cash-on-Cash Return, and the Debt Service Coverage Ratio using the 20-unit apartment example, and explains what each metric tells you about the investment.
Cap Rate: Pricing and Valuation
The Capitalization Rate expresses NOI as a percentage of property value or purchase price. It is both a pricing metric (what am I paying per dollar of income?) and a valuation tool (what is this income stream worth?). For our 20-unit building: Cap Rate = NOI / Price = $140,220 / $2,000,000 = 7.01%. A higher cap rate indicates a higher yield per dollar invested—but also typically signals higher risk or lower-growth markets. Cap rates compress in prime locations (4-5%) and expand in secondary/tertiary markets (7-10%). Critically, Cap Rate is an unlevered metric—it ignores financing entirely, making it useful for comparing properties regardless of how they are financed.
Why it matters: Cap Rate = NOI / Purchase Price Example: $140,220 / $2,000,000 = 7.01% As a valuation tool: Property Value = NOI / Cap Rate Example: $140,220 / 0.07 = $2,003,143
Cash-on-Cash Return: Measuring Equity Efficiency
Cash-on-Cash Return measures the annual pre-tax cash flow as a percentage of the total cash invested—it tells you how hard your equity is working. First, calculate Before-Tax Cash Flow (BTCF): NOI minus Annual Debt Service. For our 20-unit example, assume a $1,600,000 loan (80% LTV) at 6.5% interest, 30-year amortization. Annual debt service = $96,000 (approximately $8,000/month). BTCF = $140,220 - $96,000 = $44,220. Total cash invested includes the $400,000 down payment plus $25,000 in closing costs = $425,000. Cash-on-Cash Return = $44,220 / $425,000 = 10.4%. If we use only the down payment: $44,220 / $400,000 = 11.1%. Unlike Cap Rate, Cash-on-Cash is a levered metric—it reflects the impact of financing on equity returns.
Why it matters: BTCF = NOI − Annual Debt Service BTCF = $140,220 − $96,000 = $44,220 Cash-on-Cash = BTCF / Total Equity Invested Using down payment: $44,220 / $400,000 = 11.1% Including closing costs: $44,220 / $425,000 = 10.4%
DSCR: The Lender's Safety Metric
The Debt Service Coverage Ratio measures how many times NOI covers the required debt service payments. It is the primary metric lenders use to evaluate loan risk. DSCR = NOI / Annual Debt Service = $140,220 / $96,000 = 1.46x. A DSCR of 1.46x means the property generates 46% more income than needed to pay the mortgage. Most commercial lenders require a minimum DSCR of 1.20-1.25x, with agency lenders (Fannie Mae, Freddie Mac) typically requiring 1.25x for multifamily. A DSCR below 1.0x means the property cannot cover its debt from operations—a red flag that should halt any acquisition. The spread between actual DSCR and the lender minimum (here, 1.46x vs 1.25x = 0.21x cushion) represents the safety margin for income shortfalls.
| DSCR Range | Assessment | Lender Response | Investor Action |
|---|---|---|---|
| <0.90x | Negative cash flow — property cannot cover debt | Decline / Require recourse | Pass unless massive value-add upside |
| 0.90-1.00x | Breakeven — no safety margin | Decline or heavy conditions | High risk; only for forced appreciation plays |
| 1.00-1.15x | Thin coverage — vulnerable to ANY expense increase | Conditional approval with reserves | Negotiate rate buy-down or lower leverage |
| 1.15-1.25x | Adequate — meets most lender minimums | Standard approval (DSCR loans) | Acceptable for stabilized properties |
| 1.25-1.50x | Strong — comfortable safety margin | Favorable terms, lower rate tier | Target range for buy-and-hold acquisitions |
| 1.50-2.00x | Excellent — significant cash flow buffer | Best rates, max LTV offered | Ideal; consider increasing leverage to boost returns |
| >2.00x | Exceptional — may indicate under-leveraging | All programs available | Evaluate if equity is deployed optimally |

Why it matters: DSCR = NOI / Annual Debt Service DSCR = $140,220 / $96,000 = 1.46x Interpretation: < 1.0x = Property cannot cover debt (deal-killer) 1.0-1.20x = Thin margin, most lenders decline 1.20-1.25x = Minimum for most commercial loans 1.25-1.50x = Healthy coverage, standard range > 1.50x = Strong coverage, room for stress

Common Mistakes to Avoid
Assuming lower cap rates always indicate better investments
Consequence: Low cap rates may reflect overpriced markets or compressed yields with limited upside
Correction: Evaluate cap rates relative to local market averages, property risk profile, and growth potential
Ignoring DSCR when evaluating levered returns
Consequence: A property with high Cash-on-Cash but DSCR below 1.25x is one vacancy spike away from negative cash flow
Correction: Always verify DSCR exceeds 1.25x before relying on levered return projections
