The first component of cash flow is rental income, which is the money you collect from tenants. This can include base rent, parking fees, and any additional charges like late fees or pet fees. When estimating rental income, it’s important to factor in potential vacancies. If your property is not rented 100% of the time, you may want to account for vacancy loss by reducing the expected rental income slightly.
