The Complete Guide to Analyzing Rental Property Investments in Greater Boston: Cap Rates, Cash Flow, and ROI Calculations

Rental property investment requires systematic financial analysis using industry-standard metrics: Cap Rate (net income ÷ property value), Cash-on-Cash Return (annual cash flow ÷ cash invested), and Net Operating Income (gross rental income - operating expenses). Greater Boston rental yields typically range from 3-6% depending on location, property type, and market conditions. Positive cash flow is rare without 30%+ down payments in high-cost markets like Boston. Professional investors model multiple scenarios (vacancy, maintenance, market changes) and require 15%+ total return (appreciation + cash flow) to justify the risk and illiquidity of real estate investment.
