Sources
Kefiw uses source families that fit property decisions: official references where rules matter, visible assumptions where estimates vary, and reviewer lanes where scope and workflow judgment matter.
Source families used on property pages
- Cost calculators: visible formulas, editable assumptions, line-item ranges, and scope notes instead of fake exact quotes.
- Damage pages: FEMA/NFIP/FloodSmart flood basics, EPA mold and moisture-control guidance, insurance education, contractor scope review, and claim-boundary wording.
- Repair pages: contractor scope review, trade and manufacturer context where relevant, permit or local-rule prompts, and quote-comparison questions.
- Buy/Sell pages: realtor workflow review, closing-cost line items, seller proceeds assumptions, repair-credit framing, and document prompts.
- Outside-help links: certification-based, official, association, or locally verifiable directories where possible.
Damage and insurance-adjacent pages
Property pages use a mix of visible calculator formulas, contractor scope review, realtor workflow review, public insurance regulator guidance, FEMA/NFIP flood references, EPA mold and moisture guidance, local permitting or code references where relevant, manufacturer or trade references when needed, and clearly labeled assumptions for local cost variation.
Damage and insurance-adjacent pages do not interpret a user's specific policy, adjust claims, provide legal advice, or guarantee coverage. Policy language, local rules, contractor scope, and insurer decisions can change the outcome.
How sources are chosen
Kefiw prefers primary or official sources when the page depends on current rules, thresholds, or standards. When a page uses a simplified estimate model, the page should say so. Source quality matters, but matching the source to the property decision matters too.
Why source limits are disclosed
A planning estimate can be useful without being a contractor quote. A claim-or-cash calculator can organize the money question without deciding coverage. A restoration bid checker can identify missing proof without judging every local contract term. Kefiw tries to keep those boundaries visible instead of hiding them under generic accuracy claims.
What users are usually trying to do
Users checking the sources page are usually trying to decide whether Kefiw is credible enough for the property task in front of them. They want to know whether the tool shows real assumptions, whether the page is honest about uncertainty, and whether outside-help links are separated from the result.
