Buying a rental property looks simple on paper: a tenant pays you rent every month, and the property (theoretically) takes care of itself. But the real math behind rental real estate is far more layered — and far riskier — than most people realize.
This video breaks down exactly how landlords make money (base rent, annual increases, fees) and exactly how they lose it (mortgage, taxes, insurance, vacancy, and the infamous 50% rule). Then we look at a real case: a New York City landlord controlling around 5,000 rent-stabilized apartments that filed for bankruptcy in 2025 — not because units sat empty, but because the entire business was built on an assumption that stopped being true.
