Does WeCostSeg serve all 50 states?

Yes. WeCostSeg serves real estate investors in all 50 US states. Residential studies use a virtual walkthrough regardless of property location. Commercial studies use an in-person inspection where travel costs for remote commercial properties are quoted separately. State conformity for bonus depreciation is addressed in the state-by-state pages linked from the site.

What property types does WeCostSeg work with?

Five investor profiles: W-2 high earners qualifying for the short-term rental loophole on their first STR, real estate professionals running portfolios of 5 to 50 properties, small-to-mid commercial owners (office, retail, restaurant, industrial, self-storage, medical, hotel), post-January-19-2025 acquirers using OBBBA 100% bonus, and long-hold owners running Form 3115 look-back studies.

How is WeCostSeg different from large specialty tax firms?

Large specialty firms route clients through account managers, junior associates, and review chains before an engineer touches the work. At WeCostSeg the founder is the person you reach on WhatsApp. Engineering review is real, not nominal. Pricing is posted publicly at $795, $2,495, and $2,995+. Five years of audit defense is included on every study.

What is included in the 5-year audit defense?

Every WeCostSeg study includes five years of written audit defense from the delivery date at no extra charge. If the IRS opens an examination within that window, WeCostSeg produces archived photographic evidence, source documentation, methodology support, and Section 1245 vs 1250 classification rationale. The defense aligns to the 13 Principal Elements in Chapter 4 of IRS Publication 5653.

How does WeCostSeg coordinate with my CPA?

Every engagement follows a three-touch CPA Coordination Protocol: your CPA is CC'd on the preliminary analysis at intake, receives the draft report five business days before final delivery for allocation review, and coordinates on Form 3115 prep when a Section 481(a) adjustment applies. This runs on all three pricing tiers at no additional charge.

How fast can I get a proposal from WeCostSeg?

Within four business hours during US Eastern hours. The free preliminary analysis returns a written estimate of your first-year deduction and a quoted study fee. No payment or contract is required. Send property details via the free proposal form or WhatsApp. Requests submitted outside US Eastern business hours receive the response on the next business morning.
