Cap Rate FAQs
What's a good cap rate?
A "good" cap rate depends on your investment goals, risk tolerance, and market conditions. In Boston, investors typically target 6-8% cap rates for balanced risk-adjusted returns.
How does cap rate differ from cash-on-cash return?
Cap rate measures the property's income potential regardless of financing, while cash-on-cash return factors in your actual investment (down payment) and financing costs.
Can cap rates change over time?
Yes, cap rates fluctuate with market conditions. When interest rates rise or property values increase, cap rates typically rise. When interest rates fall or property values decrease, cap rates typically fall.
