Multifamily Cap Rate Arbitrage Calculator
Cap rate arbitrage is the value-add multifamily playbook: buy at higher in-place cap, lift NOI through operational improvements, refinance at lower stabilised cap. The spread between purchase and stabilised cap rate is the equity created.
How Cap Rate Arbitrage Works
Buy at 8% cap. Improve operations to lift NOI by 30%. Refinance at 5.5% market cap rate. The new valuation reflects the higher NOI at the lower cap, creating equity. This is the core multifamily syndication playbook.
Typical Operational Improvements
Three highest-NOI levers: bring rents to market (often 5-15% gap on in-place leases), add RUBS (resident-paid utilities), and reduce operating expenses via management efficiency or scale. Combined, these typically lift NOI 20-40% over 18-24 months.
Exit Cap Risk
The biggest threat to cap rate arbitrage is interest rate movement compressing exit caps. A 75 bps cap rate move (5.5% → 6.25%) reduces value by 12% at the same NOI. Stress-test 100 bps upward movement before committing.
