Overview
When a unit becomes void, the clock on lost rent starts before anyone has written a line of listing copy. The leasing marketer still needs particulars that match the building, a floor-plan description that a prospect can picture, and portal text that fits character limits and house style. This page is for that person: the one who turns specs and photos into a publishable marketing pack, not the surveyor who measures the void and not the agent who later conducts viewings.
The generator does not publish. It drafts. Leasing still decides what goes live, which photos are used, and whether any claim about condition, amenity, or availability is safe to state.
What the pack is for
A re-letting marketing pack is the set of words that sit next to the photos and the measured survey. It is not a valuation, a dilapidations schedule, or a legal notice. Those documents live elsewhere in the vacate process. The pack exists so a prospect, a portal, and an internal CRM all receive the same facts about the same unit, without a leasing coordinator dictating layout, finishes, and amenities from memory on a call.
Typical contents are a long-form particulars document (the PDF or word-processed sheet sent to applicants and agents), a short floor-plan description that explains what the drawing shows, and one or more portal listings truncated to each site's field limits. Some teams also want a viewing-brief paragraph for the agent. The generator can produce that paragraph from the same inputs, still as a draft.
Speed is the outcome. The bottleneck is rarely photography itself. It is the hours spent turning a mix of old particulars, a CAD export, and a photo dump into copy that does not contradict the building. A model that has the current specification and the current photos can assemble a first draft in minutes. Leasing still spends time on review, but that time is spent checking claims rather than writing from a blank page.
Inputs the generator must have
The model should not invent a unit. It needs a building specification that identifies the asset and the demise, and it needs photos that show the spaces the copy will describe. If either is missing, the correct output is empty, with a short reason that leasing can act on (for example, "no floor-plan file" or "photo set not attached"). A half-written listing from last year's brochure is worse than no listing: it will be pasted onto a portal and then corrected in public.
A usable specification typically includes address and unit identifier, measured areas and a room schedule, tenure and use class where those are already confirmed, parking and amenity lists that are contractual rather than aspirational, and any constraints leasing already knows (no pets, no external signage, service-charge notes that belong on particulars). Floor-plan files belong with the spec when they exist: CAD, PDF, or a labelled image. The generator describes what the plan shows. It does not redraw the plan.
Photos should be tagged to rooms or elevations where possible. Unlabelled dumps still work if there are enough frames to cover the principal spaces, but the draft should stay silent on any room that cannot be seen and is not listed on the spec. Do not let the model "complete" a kitchen from a corridor shot.
Optional inputs improve the draft without being required: previous particulars (for tone only, never as a substitute for current measurements), portal field templates, and a short brand voice note (sentence length, whether to name the landlord, whether to mention nearby transport). Previous copy is a style hint. If it disagrees with the current spec, the spec wins.
When photos show damage, remaining tenant chattels, or incomplete strip-out, the draft should describe the space as shown or omit condition language, not promise a refurbished finish. Condition claims belong with the dilapidations and make-good work, not with marketing adjectives.
What a complete draft looks like
The particulars draft should open with facts a prospect uses to filter: location, size, use, availability date if known from the vacate file, and the number of floors or rooms. Then it should walk the demise in the same order as the floor plan, so a reader can follow the drawing. Each room paragraph should stick to what the spec and photos support: dimensions where measured, fittings that are visible or scheduled, natural light only when a window is evidenced. Adjectives that cannot be checked (stunning, unique, recently refurbished) stay out unless leasing adds them after seeing the unit.
The floor-plan description is not a repeat of the particulars. It is a legend in prose: what north is, which door is the entrance, how the rooms connect, where the risers or cores sit if they appear on the drawing, and which measurements are from the survey versus indicative. If the plan is a marketing drawing rather than a measured survey, the draft must say so. Prospects and agents treat those two documents differently.
Portal copy is the same facts under a character budget. Produce one version per portal template you were given, not a single blob that leasing has to crop. Headlines should name the asset type and location, not a slogan. The first sentence of the description should repeat size and use so a search snippet still makes sense. Do not stuff synonyms. Portal quality filters and reader patience both punish that.
A viewing-brief paragraph, if requested, is for the agent: access instructions that were in the spec, keys or fob notes, and any hazards visible in photos (open risers, remaining kit). It is operational, not promotional.
Every draft should carry a source note: which spec version and which photo set were used, and which fields were left blank because evidence was missing. That note is for leasing, not for the portal.
Review, edit, and publish
Leasing remains the publisher. The workflow is draft, check, then export to the portal and the particulars template. The check is not a spelling pass. It is a fact pass.
Confirm that areas, room counts, and parking match the specification, not the old listing. Confirm that photos attached to the live listing are the same set the model saw, or that any swapped image is still consistent with the copy. Confirm availability and rent only if those figures came from the leasing file. If they did not, leave them out of the draft and fill them in the CMS by hand.
Legal and compliance review still sits with whoever already signs off particulars in your organisation. Energy certificates, EPC language, material information rules for listings, and equalities wording are not things a generator should improvise. If the spec does not include them, the fields stay empty until a human supplies the approved text.
After publish, keep the draft and the source note with the void file. When the unit is re-let, you will need to show what was marketed. That archive also feeds the next void: the next marketer should start from the last approved particulars plus new photos, not from a portal scrape.
When to return nothing, and what this page does not cover
Return no marketing copy when the building specification is missing, incomplete as to demise identity or area, or clearly for a different unit. Return no marketing copy when there are no photos of the void in its current state. File-name-only folders, last-tenancy brochures, and CGI of a proposed refurbishment are not current photos. Staging images from a previous campaign belong in a separate, labelled optional input; if they are mixed into the live set without a label, treat the photo input as unusable.
Also return empty, with a reason, when the spec and photos contradict each other in a way the model cannot resolve (for example, the schedule lists three meeting rooms and the photos show an open floor with no partitions). Contradiction is a briefing problem. Inventing a layout to "help" leasing will create a misdescribed listing.
This generator does not assess dilapidations, score make-good, or decide whether a break notice was valid. It does not assemble the move-out document pack. It does not set rent. It does not replace measured survey. Those jobs remain with survey, legal, and asset management. Marketing copy that pretends the unit is already in the state the landlord hopes to achieve after works is a misdescription risk. Keep the pack aligned with what a viewer will see on the first appointment, or state clearly that photos are of works in progress, if leasing has approved that framing.
Used this way, the model shortens the path from void to live listing without taking the publish button. The marketer still owns the particulars. The generator only fills the first page so that ownership is review, not authorship from scratch.
Is this worth automating for you?
Whether this pays back depends on how much time it takes your team today. Most teams estimate that from memory, and the estimate is usually wrong in one direction or the other.
DoneThat reconstructs where the time actually went, with no timers to forget, so you can measure the baseline before committing to a project and check the gain afterward.
