Frequently Asked Questions

What is the purpose of a cost allocation plan?

A cost allocation plan in real estate serves to systematically categorize and assign property purchase costs to different asset classes based on their useful lives. This strategic allocation allows property owners to accelerate depreciation by identifying components that qualify for shorter recovery periods (5, 7, or 15 years) rather than depreciating the entire property over 27.5 or 39 years. The plan transforms a single lump-sum acquisition into a detailed breakdown of building systems, personal property, land improvements, and structural elements. This creates immediate tax deductions, increases cash flow, and provides IRS-compliant documentation that withstands audit scrutiny while maximizing the financial benefits of real estate ownership.
