Property document checklist before marketing

Check sale documents before a listing goes live. For estate agents and conveyancing support staff preparing a property for sale.

4 min read

Use this pack to turn a mixed property file into a decision your branch can act on: list, list with tightly controlled wording, or pause. It is for the agent or support worker who has documents but needs a reliable account of what is missing before the property is marketed.

The prompts do not replace the conveyancer, building professional or other qualified reviewer. Their purpose is narrower: create an evidence trail, stop unsupported claims entering the listing, and give the case owner a named next action.

Key point

Start with evidence, not the draft listing

A statement in the seller's email is a lead to check. It is not proof for the listing.

Run the prompts in this order

  1. Start with Document intake and evidence index. Paste filenames and document text where possible. If you only have scans, include what you can read and mark poor scans as unreadable. This first output is your case inventory.
  2. Run Title and tenure marketing flags when title material, a lease or management information is available. Use it to check that phrases such as freehold, allocated parking, private garden or long lease are supported, rather than assumed.
  3. Run Planning and compliance evidence review where works have been mentioned or are visible in the floorplan, photographs or inspection notes. Keep certificates, invoices and seller statements separate. They are different types of evidence.
  4. Run EPC and floorplan consistency check before finalising bedrooms, room labels, measurements, heating wording and energy statements. Paste the proposed copy, not just the documents.
  5. Finish with Final marketing readiness decision. Paste the outputs from the earlier prompts in full. Assign every required action to a person or team before the listing is released.

If the file is small, you can begin with the final prompt. You will get a better result, and a clearer audit trail, by using the earlier prompts first.

Note

Keep the source beside each finding

A useful checklist says where the statement came from, such as the EPC, title register, seller form or inspection note. It does not simply say documents checked.

Prepare the material before pasting

Give each file a plain label before you paste it. For example: EPC, issued [date], floorplan, agent version [date], or seller property form, incomplete. Include the property address as it appears on each document. Flat numbers, plot numbers and postcodes often expose a mismatch that would otherwise be missed.

Remove information that the reviewer does not need, such as bank details, signatures and unrelated personal correspondence. Do not remove dates, issuer names, reference numbers, property descriptions or the wording around an approval, restriction or certificate. Those fields are often what allows a document to be matched to the property.

Document upload and handling options can vary with the model you are using. Check the current guidance in the xAI documentation overview. If a scan cannot be read accurately, type the relevant wording or ask for a clearer copy. Do not rely on a guessed reading of a plan, stamp or certificate.

Watch out

Do not convert absence into a conclusion

No certificate supplied does not mean the work was unauthorised. It means a certificate or specialist confirmation is still needed before you make a claim based on it.

Check the final decision

Read the final output beside the actual documents. Checking matters most where the model has joined two similar facts that belong to different documents or properties.

Use this quick review table before marking the case ready:

If you see this Check Then do this
A confident statement with no source Whether a document and page are named Mark it unresolved until evidence is supplied
The same address written differently Flat, unit, plot and postcode details Ask the seller or conveyancer to confirm the correct property reference
A certificate for a stated alteration Work description, date, issuer and property address Hold the related marketing claim if any field does not match
A floorplan room called a bedroom The seller form, inspection notes and proposed copy Use neutral room wording until the agent confirms the description
A title or lease entry summarised as a marketing benefit The exact original wording Refer interpretation to the conveyancer and remove the claim if needed

Check

A checklist is complete when every blocker has an owner

Each unresolved item should name the missing document or verification, the person who must provide it, and the listing claim affected.

The output is wrong, or at least unsafe to rely on, when it overlooks an address mismatch, treats an invoice as an approval, silently resolves conflicting dates, or repeats a seller claim as a fact. It is also wrong when it gives a marketing-ready result while key documents were not supplied. Correct the source material, then rerun the relevant prompt rather than editing the conclusion by hand.

When the pack does not work

If the answer is generic, paste fewer documents at once and start with the intake prompt. If it misses a document, add its full title, date, issuer and the relevant text. If scans are unclear, obtain a clearer copy or record the item as unreadable. If the issue turns on title wording, lease terms, planning status, building standards or safety, stop treating it as a copywriting task and send the exact question and source document to the conveyancer or qualified specialist.

Stop

Do not publish around an unresolved material conflict

Removing the difficult wording from the draft does not fix a mismatch in the property file. Record it, assign it, and obtain the evidence or professional confirmation.

Copy-ready prompts

5 prompts. Open one to read it, or take the whole pack.

1Document intake and evidence indexUse this first when documents have arrived from the seller, another agent, a conveyancer or a shared case folder.
You are preparing an internal pre-marketing document index for a residential property sale. Do not provide legal advice or decide legal validity. Record only what the supplied material says, what is absent, and what needs verification by the responsible agent, seller or conveyancer.

Property address: [property address]
Jurisdiction, if known: [England / Wales / Scotland / Northern Ireland / other / unknown]
Seller or case reference: [reference]
Documents supplied: [paste document names, dates and contents, or attach/paste the documents]
Documents expected but not supplied: [list, or write unknown]

Create a Markdown table with these columns: Document category | Document title or description | Date and issuer | Present, partial, unreadable or absent | Property/address match | Key fields found | Concern or gap | Owner of next action.

Use these document categories: title or title register; title plan; EPC; floorplan; property information forms; fittings and contents information; planning permission; building regulations approval or completion record; listed-building or conservation-area material; warranties; guarantees; electrical records; gas records; heating or boiler records; fire or other safety records; leasehold or management information; insurance or claims information; other.

Then provide:
1. A section called `Immediate missing documents` with only documents that appear absent or incomplete.
2. A section called `Identity and address mismatches` listing every differing address, flat number, plot number, postcode, title number, seller name or document date.
3. A section called `Questions to send` with concise questions for the seller or document holder.

If a document is illegible, conflicting, undated, incomplete or not clearly tied to this property, mark it `needs verification`. Do not infer that approval, consent, ownership, compliance or a right exists because related papers are present.
2Title and tenure marketing flagsUse this after the title material is available. It gives the marketing team a factual flag list without asking the model to interpret title documents as a…
Review the supplied title and tenure material for an internal property-marketing review. Do not provide legal advice, confirm marketable title, or interpret legal effect. Extract stated facts and identify items for conveyancer or seller verification.

Property address: [property address]
Jurisdiction, if known: [jurisdiction or unknown]
Title register, title plan, lease, management pack or related material: [paste or attach documents]
Known listing facts proposed by the agent: [tenure, property type, parking, garden, access, service charge, ground rent, restrictions, or unknown]

Return these sections in Markdown:

`1. Extracted property and tenure facts`
Use a table with: Field | Exact wording or value found | Source document and page/section | Confidence. Include title number, registered proprietor name if shown, tenure, lease term if shown, property description, plan reference, rights or easements mentioned, covenants or restrictions mentioned, rentcharge, service charge, ground rent, managing agent and parking/access references.

`2. Listing claims to verify`
For each proposed claim, use a table: Proposed claim | Evidence found | Status (`supported`, `not found`, `conflicts`, `needs conveyancer check`) | Required action. Check, where relevant: freehold or leasehold wording; length of lease; allocated parking; driveway; garage; garden; shared access; rights of way; views; development potential; pets; letting; alterations; and charges.

`3. Marketing flags`
List only factual flags which should be resolved, qualified or referred before publication.

`4. Questions for the conveyancer or seller`
Write short, neutral questions. Quote the relevant document wording where useful.

When wording is unclear, preserve the wording and say `meaning not determined`. Do not turn a plan line, covenant, restriction, notice or register entry into a marketing conclusion.
3Planning and compliance evidence reviewUse this where the seller mentions an extension, loft conversion, replacement windows, a new heating system, electrical work or another alteration.
Prepare an internal evidence review for planning, building work and property compliance records. This is not legal, building-control or safety advice. Do not state that works are authorised, compliant, safe or exempt unless the supplied document expressly says so. Where a decision depends on local rules or professional interpretation, state `requires specialist verification`.

Property address: [property address]
Jurisdiction and local authority, if known: [details or unknown]
Seller's stated works and dates: [paste]
Planning papers, building-control records, certificates, warranties, guarantees, electrical records, gas or boiler records, invoices and correspondence: [paste or attach]
Proposed marketing references to works: [paste]

Return a Markdown table with: Work or feature | Seller claim | Evidence supplied | Issuer and date | Address match | Reference number | Evidence status (`present`, `partial`, `absent`, `conflicting`, `unreadable`) | Verification needed before marketing.

Cover extensions, loft conversions, garage conversions, structural changes, windows and doors, heating and boiler installation, electrical work, drainage, solar panels, insulation, chimneys, fire safety items and any other stated work.

Then provide:
1. `Claims to remove or hold` listing each proposed listing claim that lacks clear supporting evidence.
2. `Documents or confirmations to obtain` grouped by seller, installer, local authority, managing agent and conveyancer.
3. `Conflicts` identifying differing dates, addresses, descriptions of work, installer names or completion details.

If paperwork is present but does not match the property address, the stated work, or the date range, do not treat it as evidence for this property.
4EPC and floorplan consistency checkUse this before drafting room descriptions, measurements, feature bullets or energy wording. It catches the common problem of a floorplan or EPC describing a…
Compare the supplied EPC, floorplan, property information forms and proposed listing facts for a residential property. Produce an internal accuracy check, not an energy assessment or legal opinion.

Property address: [property address]
EPC: [paste or attach]
Floorplan: [paste or attach]
Property information forms: [paste or attach]
Proposed listing facts and draft copy: [paste]
Current photographs or agent inspection notes, if available: [paste]

Return these sections in Markdown:

`1. Property facts comparison`
Create a table: Fact | EPC | Floorplan | Property form | Draft listing or notes | Result (`consistent`, `conflict`, `not stated`, `needs inspection`) | Action. Compare address, property type, bedroom count, room labels, total area if shown, heating type, fuel, glazing, parking, garden, outbuildings, extensions and energy rating.

`2. Copy that is safe to retain`
List only draft statements directly supported by the supplied documents.

`3. Copy to amend, remove or verify`
For every unsupported or conflicting statement, give the exact statement, why it is a problem, and the next evidence needed.

`4. Inspection questions`
Write a short checklist for the agent's next visit. Include only items that cannot be resolved from the documents.

Do not calculate room sizes, infer bedroom status from a room label, or state that an improvement has been installed because it is recommended in an EPC. If documents disagree, show both sources and mark the item `needs inspection` or `needs verification`.
5Final marketing readiness decisionUse this last, once the available documents have been indexed and checked. It gives the case owner a short decision and an actionable list of what must happen…
Make an internal marketing-readiness decision from the supplied property document review. This is an operational checklist, not legal, financial, safety or conveyancing advice. Do not decide legal title, compliance, safety or value. Base every finding only on the evidence provided.

Property address: [property address]
Jurisdiction, if known: [jurisdiction or unknown]
Document index and review findings: [paste]
Title and tenure findings: [paste]
Planning and compliance findings: [paste]
EPC and floorplan findings: [paste]
Current draft listing claims: [paste]
Known deadlines or launch date: [paste or unknown]

Start with exactly one line in this format:
`Marketing readiness: READY / READY WITH HOLD POINTS / NOT READY TO LIST`

Apply these meanings:
- `READY`: no unresolved issue in the supplied review prevents the stated listing claims from being published, subject to normal agent approval.
- `READY WITH HOLD POINTS`: the property may be prepared or marketed only if specified claims are omitted, qualified or held pending verification.
- `NOT READY TO LIST`: a key identity, tenure, property-description, document, planning, compliance, EPC or floorplan issue remains unresolved and could make the listing materially inaccurate.

Then return:
1. A `Decision basis` table: Issue | Evidence reviewed | Risk to listing accuracy | Required action | Owner | Status.
2. `Must obtain or verify before listing`, numbered in priority order. Each item must name the document, confirmation or inspection needed; who should provide it; and what listing claim it affects.
3. `May list only if these claims are removed or qualified`, with exact replacement wording where possible.
4. `Can be completed after listing preparation starts`, limited to non-blocking tasks.
5. `Escalate to the conveyancer or qualified specialist`, listing only matters that require professional interpretation.

Treat missing, unreadable, conflicting or address-mismatched evidence as unresolved. If the supplied material is too thin to support a decision, choose `NOT READY TO LIST` and say precisely what is missing. Do not use vague actions such as `check documents`.
