Straight line capitalization assumes what type of income stream during the remaining economic life of the improvements?

Straight line capitalization is a method used in real estate appraisal to estimate the capitalization of income generated by a property. This method operates on the assumption that the income stream generated by the property will remain stable over time, implying that there will be no significant fluctuations in income. However, in this specific context, the correct answer relates to the assumption of declining income streams during the remaining economic life of the improvements.

When appraisers use straight line capitalization, they often account for depreciation, which reflects the natural decline in a property's income-producing capability as it ages and as its improvements wear out. The rationale behind this choice is that as properties age, they may become less appealing or may require more maintenance and repairs, leading to anticipated reductions in income.

This approach helps provide a conservative estimate of value based on the expectation that income is unlikely to increase and may indeed decrease over time as the property experiences the effects of age and market conditions. Hence, the assumption of a declining income stream aligns with the principles of straight line capitalization.
