Which of the following might serve as proof of income for a property?

Rent receipts are a reliable form of proof of income for a property because they provide documented evidence of rental payments made by tenants. Each rent receipt typically includes details such as the amount paid, the date of payment, and the tenant's information, all of which can validate the income generated from the property. By keeping accurate records of rent receipts, property managers can easily demonstrate consistent cash flow and verify income for financial assessments, lending purposes, or property valuation.

Other options, while related to property management, do not serve as direct proof of income. Inspection reports pertain to the condition of the property rather than its financial performance. Tenant leases signify a rental agreement but may not reflect actual received income, especially if there are vacancies or delayed payments. Advertising materials serve to market the property but do not provide any financial information regarding income from tenants. Hence, rent receipts stand out as the most effective documentation for proving income from property rentals.
