Frequently Asked Questions

What is cost segregation and how does it benefit real estate investors?

Cost segregation is an IRS-approved engineering-based tax strategy that analyzes your property and reclassifies building components into shorter depreciation periods (5, 7, or 15 years) instead of the standard 27.5 or 39 years. This accelerated depreciation significantly increases your upfront tax deductions, reducing taxable income and boosting cash flow in the early years of ownership. Most clients achieve first-year savings averaging $171,243, with ROI ratios typically ranging from 10:1 to 25:1. The strategy is particularly effective for properties with a building basis of $300,000 or more, allowing you to reinvest tax savings into your next acquisition or property improvements while remaining fully IRS-compliant.
