AI can hallucinate, rely on bad data, or miss property-specific context. Basis uses software for speed, then grounds the work in structured inputs, cost segregation methods, and professional review.
Traditional firms often mean proposals, calls, and unclear timelines. Basis starts with a free estimate, clear residential pricing, online intake, and a reviewed report package.
Basis uses saved-property accounts, protected report access, and secure checkout. Your property details are handled through the app, not a casual AI chat prompt.
It identifies property components that may qualify for shorter depreciation timelines, which may improve upfront cash flow.
The estimate takes about five minutes. Full reports are prepared after payment, completed intake, and professional review.
