Step-by-step worked examples

Tom buys a duplex for $300K with 20% down ($60K). Monthly rent is $2,500 (each unit $1,250). Expenses average $800/month. What's his annual cash flow?

Annual rent: $2,500 × 12 = $30,000
Annual expenses (mortgage, tax, insurance, maintenance): $800 × 12 = $9,600
Annual cash flow: $30,000 − $9,600 = $20,400
Cash-on-cash return: $20,400 / $60,000 = 34% first year

Lisa invests $100K in a rental property 10 years ago. Today it's worth $250K, and she's collected $120K in net rental income. What's her total return?

Appreciation: $250K − $100K = $150K
Cash flow collected: $120K
Total gain: $150K + $120K = $270K
Total return: $270K / $100K = 270%

A commercial property earns $50K/year net operating income (NOI) and sells for $500K (NOI method). What's the capitalization rate?

Cap rate = NOI / Property Value
Cap rate = $50K / $500K = 10%
Higher cap rate = higher risk or better undervalued deal; compare to market averages (6–8% typical)
