Real Estate Economics: Governing Investment Yield with Cash-on-Cash Return
While gross cap rates ignore mortgage obligations, Cash-on-Cash Return (CoC) represents the gold standard for income property underwriting. It measures exact net dollar cashflow generated per dollar of out-of-pocket equity invested.
1. Core Real Estate Underwriting Equations
- Cash-on-Cash Return (%):
(Annual Pre-Tax Cash Flow / Total Cash Invested) × 100 - Net Operating Income (NOI):
Effective Rental Income − Operating Expenses - Pre-Tax Cash Flow:
NOI − Annual Debt Service (Principal & Interest) - Total Cash Invested:
Down Payment + Closing Costs + Initial Renovations
2. Actionable Guidelines for Property Investors
Enhance investment performance by stress-testing debt service coverage ratios (DSCR) against 5% vacancy assumptions, deploying strategic cosmetic upgrades to lift baseline market rents, and optimizing acquisition loan terms.
