Build the file in layers. Use ZIP, state and tract data only as context; match the exact home or unit across the assessor record, flood map, insurance documents, inspection reports, permit authority, utility responsibility, association file, title commitment and survey. For every item, record the source, effective date, geography and limitation. A returned record is not automatically current or property-bound, and a missing result is not proof of low risk, legal work or a clean file.
Finding the next official source—not proving a fact about the parcel
Checking identity, scope, effective date and the issuing authority
Answering the exact tax, coverage, condition, title or service question the document controls
These layers are not scores. Stronger evidence can answer a narrower question, while a Missing, Stale, Context only or conflicting item stays open until the responsible source or professional resolves it.
Lock the subject before collecting conclusions
Start by making sure every record refers to the home you intend to buy. Compare the street and unit, assessor parcel identifier, legal description, building or association name and any phase or lot reference across the contract, assessor pathway, title material and survey or plat. Similar mailing addresses, unit labels and subdivision names can point to different legal subjects.
A Census Geocoder response is a calculated geographic match used to locate the search. It does not establish parcel boundaries, ownership, legal description, taxing authority, permit jurisdiction or title. Treat the matched point as a lead, then confirm the property identity in the records that control each question.
- Keep the full address and private identifiers in the transaction file—not in a share URL
- Record the exact record year or effective date
- Mark a mismatch as a conflict instead of choosing the more favorable result
Separate the seller's tax record from the buyer's tax plan
Request the current parcel assessment and tax bill from the local assessor or tax collector and identify every taxing district and separately stated tax assessment. Record the tax year, assessment date, exemptions and payment status. A statewide effective rate or ACS benchmark is useful context, but it is not the bill for this property.
Then ask what may change after the purchase: assessment cycle, transfer or sale-price treatment, exemption removal, buyer application deadlines and tax special assessments. Keep the Loan Estimate or Closing Disclosure escrow estimate separate. The seller's bill and the closing estimate do not guarantee the buyer's later bill or exemption eligibility.
Keep flood and hazard context in its geographic lane
Open the official FEMA Map Service Center result for the property, record the effective panel or product date and preserve any relevant Letter of Map Change or elevation evidence supplied for the transaction. A map intersection at a geocoded point is not a parcel survey, elevation certificate, title record, insurance determination or promise about future flooding.
Community or tract-level risk data can help surface questions about flood, wildfire, wind or other hazards, but it remains context. If a map service returns nothing or is unavailable, mark the item Missing or unavailable and continue with the responsible authority and insurer. Never translate a failed lookup into low or no risk.
Build the insurance file around issued terms, not the premium alone
Obtain an address-specific written quote and, when the transaction reaches that stage, the binder or issued policy evidence. Review Coverage A or the applicable property limit, loss-settlement basis, standard and peril-specific deductibles, exclusions, sublimits, ordinance-and-law treatment, water backup and whether wind or flood requires separate coverage. Record the quote or issue date and binding status.
A premium amount does not prove coverage, replacement-cost adequacy, availability, binding or a future claim outcome. State averages and historical NAIC data are planning context. Use the state insurance department directory to find the regulator, and ask the carrier or licensed professional to explain the documents for this exact property.
Turn the inspection into a map of what remains unseen
Read the signed general inspection report beside its scope, date and list of inaccessible, not-operated or excluded areas. Then attach the dated specialist reports the property actually calls for—such as roof, structure, foundation, moisture, electrical, plumbing, HVAC, sewer, septic, well, chimney, pool or environmental follow-up.
Receipt or user review is not authentication and does not make a home pass. A report does not by itself determine severity, repair cost, code compliance or remaining life. Keep unresolved observations open, and route technical conclusions to the qualified professional responsible for them.
Confirm the permit authority before reading the permit result
A mailing city, ZIP code or candidate portal does not necessarily identify the authority having jurisdiction. Confirm which city, county, district or other authority governs the address, then search the official record and match any permit to the property and described work. Where available, distinguish application, issued permit, inspection, final approval and certificate-of-occupancy records.
No search result is not proof that no permit was required, no permit exists or work was illegal. An issued or finalized permit also does not establish present condition or blanket code compliance. Compare the public record with seller disclosures, invoices, warranties and the inspection file, then ask the authority about gaps.
Reconcile utilities, service responsibility and association coverage
Confirm the exact electric, gas, water, sewer, waste and broadband service pathways for the address. Use a recent property bill or seller-provided usage as historical context, then check the current official rate or tariff and what the buyer must establish. EIA state averages are not a utility tariff, and provider-reported broadband availability does not promise price, speed or installation.
Mark which services are included in association dues so the same cost is not counted twice. For public water, identify the serving system and its current Consumer Confidence Report; for a private well or septic system, collect the property records and specialist evidence that apply. If the property is a condo, townhome or known association home, keep the governing, budget, reserve, insurance, assessment and building-condition file open rather than marking HOA not applicable.
Keep title, survey, disclosures and property history distinct
Review the title commitment or local equivalent, survey or plat, recorded easements and restrictions, seller disclosures, claims or loss information made available, major-system invoices and transferable warranties. For most pre-1978 housing, the federal lead disclosure rule concerns known information and available records; it is not a test or proof that lead is absent.
An assessor record does not prove clear title, a permit does not resolve an easement, and a seller disclosure does not replace inspection. Ask the closing, legal, survey, insurance and technical professionals responsible for each conclusion. HomeCostGrid organizes questions; it does not issue a title, legal, engineering or coverage opinion.
Transfer status—not the street address—into the Purchase Evidence Pack
For each area, record whether the evidence is Missing, Planning, Stale, User entered or an official document that you reviewed; then record the source class, observed or effective date, geography and limitation. Candidate authority, state benchmark and tract context stay Planning or context even when they come from an official domain. Conflicting records stay open.
Property Intelligence keeps the address in the live session, while the Purchase Evidence Pack remains a separate, device-local redacted file and does not silently import that session. Move only the status you can support into My Home. Keep raw documents, full address, parcel and policy numbers, provider names, private links, notes and dollar amounts out of redacted exports. Even a file with no currently marked gap is not verification, approval or a buy recommendation.
Match, date and limit every piece of evidence.
Request each item if applicable and available. Availability and disclosure duties depend on the jurisdiction, contract, property and loan program.

A few things worth knowing before you start.
Does a Census address match verify the parcel?
No. The Census Geocoder provides a calculated geographic match for the search. It does not establish parcel boundaries, ownership, legal description, title, taxing district or permit authority. Confirm those questions in the controlling local and transaction records.
Does a FEMA map result prove the home's flood risk or insurance requirement?
No. Record the effective map product and geography, then review property-specific survey, elevation, LOMC, lender and insurance evidence when applicable. A point lookup is not a parcel survey or coverage determination, and an unavailable result is not low risk.
Does an empty permit search prove the work was unpermitted?
No. First confirm the correct authority, record system, address identity and search range. No result can reflect jurisdiction, indexing or retention limits. Ask the authority what the result means; do not convert it into a legality or code-compliance verdict.
Does a complete checklist mean the home is safe, insurable or approved?
No. The checklist organizes evidence and open questions. It is not an appraisal, inspection, title opinion, insurance decision, lender project review, permit clearance, engineering conclusion or buy recommendation.
What should I do when an official source is unavailable?
Keep the item Missing or unavailable, record the failed pathway and contact the responsible authority or professional. Do not substitute a statewide benchmark, candidate portal or search-engine result as property-level evidence.
Does HomeCostGrid save the address in the Purchase Evidence Pack?
No. Property Intelligence uses the address only in the live session. My Home and its redacted Purchase Evidence Pack remain separate and do not silently import the address or session results. You decide which supported, non-sensitive status to record.
