Source, freshness and confidence

Rate data: none is bundled. All monetary, percentage, price and duration assumptions come from you.

Freshness: confirm current requirements with the responsible land registry, revenue or planning authority, lender, licensed valuer, surveyor, quantity surveyor or legal professional.

Confidence: high for the displayed arithmetic or checklist count; low for any legal, official, valuation, market, eligibility or approval conclusion because the tool does not make one.
