When analyzing current income potential, which document is most relevant?

The most relevant document when analyzing current income potential is existing lease agreements. These agreements provide specific details about the rental income that a property currently generates, outlining terms such as lease duration, rental rates, and tenant obligations. This information is critical for understanding not only the current cash flow generated by the property but also the stability of that income over time, as it reflects the market's acceptance of rental pricing.

Building plans, while important for understanding the structure and use of the property, do not provide information about the financial performance or income potential. Historical weather data, though it can impact property dynamics and usage, does not directly relate to income generation. Similarly, land survey reports are essential for understanding property boundaries and land use but do not give insight into income potential. Therefore, existing lease agreements offer the most direct and relevant information for evaluating a property's current income potential.
