Frequently asked questions

How do I choose between cost segregation firms?

Compare four items: pricing (WeCostSeg is $795 to $2,995+, national firms run $3,500 to $8,000+, Big 4 starts at $8,000), audit defense inclusion (WeCostSeg includes 5 years, most competitors charge extra), methodology (detailed engineering per IRS Pub 5653 vs residual estimation), and turnaround (WeCostSeg 5 to 20 business days). The comparisons hub runs each vendor pair with real numbers.

What is the difference between a Rapid Report and a Fully Engineered study?

A Rapid Report is software-assisted with engineer review, priced at $795, and works for residential under $800K basis. A Fully Engineered study performs component-by-component analysis with photographs and site inspection per Pub 5653 methodology, priced at $2,495 residential or $2,995+ commercial. Both include all 13 Principal Elements. The engineered version defends larger reclassifications on higher-basis properties.

Is DIY cost segregation software worth it?

For residential properties under $500K basis, DIY software at $395 to $995 captures the largest reclassifications with limited engineer oversight. For basis above $500K or any commercial property, a real engineering study returns 3x to 8x more first-year deduction than DIY. The DIY vs engineered comparison walks the break-even math on a $1M property.

How does WeCostSeg compare to KBKG, CSSI, or Bedford?

WeCostSeg prices at $795 to $2,995+ with 5 years of audit defense included. KBKG typically prices $4,500 to $8,000 with audit defense sold separately. CSSI prices $3,900 to $7,500 with 3 years of defense. Bedford prices $3,500 to $9,000. All four use detailed engineering methodology. WeCostSeg is founder-accessible via WhatsApp; national firms assign account managers.

Should I compare cost segregation to Section 179 or bonus depreciation?

They are complementary, not alternatives. Cost segregation identifies which components qualify for shorter recovery periods. Bonus depreciation under Section 168(k) at 100% under OBBBA (post January 19, 2025) accelerates those components into year one. Section 179 caps at $1.16M in 2025 with a $2.89M investment phase-out and cannot create a NOL. The comparison hub covers all three interactions.

How do virtual and in-person cost seg inspections compare?

Virtual inspections use client-supplied photographs, drone footage, appraisals, and blueprints. For residential and small multifamily under $2M basis, virtual meets IRS Pub 5653 quality standards. Cost is identical. In-person inspection adds 5 to 10 business days to turnaround. Fully Engineered Commercial studies over $5M basis often warrant in-person to defend larger allocations under Section 1245 vs 1250.
