Sold property marketing is the practice of using each completed sale as proof to win the next instruction on the same street. The core moves are a just-sold card to 40 to 60 neighbouring properties quoting the achieved price band, a sold post naming the area and days-to-offer, updating the sold price on your own website so it can rank, and a structured referral ask to the vendor at the point they are happiest.
It is the cheapest lead source in estate agency because the hard part, credibility with people who live nearby, is already paid for.
An agency completes on a house. The board comes down, the file closes, the vendor gets a bottle of something, and the marketing value of that sale evaporates within a week. Meanwhile forty households on the same street just watched a property sell and are quietly wondering what theirs is worth.
That moment is the highest-intent audience an agency ever gets, and it is free. This guide covers how to work it properly, including the compliance limits on what you can say about a price and the follow-up sequence that turns a completion into two more instructions.
1. Why the street around a sale is your best audience
Consider what has just happened on that road. A board went up, viewings came and went, the board changed to Sold, and a removal van arrived.
Every household within sight watched a live demonstration of the local market, and a good number of them have now wondered what their own house is worth.
They are also, at that precise moment, more receptive to a specific agency than they will be at any other time. You have the one thing every marketing message tries to manufacture and rarely achieves: local, recent, verifiable proof.
Then most agencies do nothing. The board comes down, the file closes, and the whole asset is discarded within a fortnight.
Sold property marketing is the cheapest instruction source in estate agency, because the expensive part, credibility with people who live nearby, has already been paid for by the sale you just completed.
2. The just-sold card, done properly
Most just-sold mailers are a branded template with a photo and the word SOLD. They perform poorly because they contain no information the recipient can use.
Keep the radius tight
Forty to sixty addresses immediately around the property. The entire mechanism depends on the recipient recognising the house, and recognition drops away fast with distance. A tight drop after every completion beats an occasional postcode-wide one, and costs a fraction as much.
Lead with a number
Days to offer is the strongest single figure, because it is unambiguous and it is about performance rather than price. “Under offer in 9 days, three viewings” gives a neighbour something to compare against their own experience or their expectations.
Say what it means for them
The card should connect the sale to the reader’s situation in one line: similar houses on this road are selling quickly at the moment, and here is what yours would likely achieve. Then a single, low-friction action.
| Element | Include? | Note |
|---|---|---|
| Street name | Yes | Non-negotiable. Without it the card is generic advertising. |
| Days to offer | Yes | Strongest performing figure; safe to state. |
| Number of viewings | Yes | Reinforces demand without touching price. |
| Exact sold price | Only if registered or consented | See compliance section below. |
| Price band | Yes | Safer alternative that keeps most of the impact. |
| Photo of the property | Yes | Drives recognition; use the listing hero shot. |
| Named negotiator with direct number | Yes | Outperforms a branch switchboard number. |
| QR code to an area valuation page | Optional | Useful, and only if it lands on a page about that street. |
3. What you can and cannot say about the price
This trips people up, and the rules are more workable than most agencies assume.
Once a sale is registered with HM Land Registry, the price is a matter of public record and can be quoted freely. Registration lags completion, often by a couple of months, so the figure is not immediately available for a card you want to send next week.
Before registration, quoting an exact figure needs the vendor’s consent. Asking for it at completion is straightforward and most vendors agree, particularly if the sale went well.
Get it in writing, even briefly by email.
Separately, the CAP Code requires any claim to be accurate and capable of substantiation. “Sold above asking price” needs to be true and evidenced for that property. “We consistently achieve above asking” needs evidence across your book, which most agencies do not actually have. Stating a specific, checkable fact about one sale is both safer and more persuasive than a general superlative.
The safe default
A price band plus days to offer, “sold in the £340,000s, under offer in 11 days”, keeps nearly all the persuasive force, requires no consent, and cannot be challenged as inaccurate.
4. The digital half: posts, pages and retargeting
The card handles the street. Three digital moves extend the same asset.
Keep the sold listing live
Many agency websites delete a property once it completes. This throws away a page that names a street, carries photographs, and accumulates relevance for exactly the searches you want.
Mark it clearly as sold, keep the URL, and it continues working for years.
Write the post like a person, not a banner
“Sold in 9 days on Ashfield Road, three viewings, asking price achieved” is worth more than a template graphic reading ANOTHER ONE SOLD, because it lets a neighbour judge what their own house might do. The branded graphic gives them nothing to think about.
Retarget the area around recent sales
A small paid social budget targeting the postcode sector around your recent completions, using the sold property as the creative, reaches the same audience as the card with a second impression. Keep the budget modest; this is a supporting move, not a channel.
5. The referral ask at completion
Completion day is the highest-goodwill moment in the entire relationship, and it is the one most agencies mark with a bottle of wine and no request.
Make the ask specific. General requests to spread the word produce nothing because they give the vendor no action to take. Two versions work:
- The review. A direct link, sent the same day, with a sentence explaining that it genuinely helps a small local business. Volume of recent reviews is one of the few local search signals you can actually influence.
- The named introduction. If the vendor mentioned during the process that a neighbour or relative was considering a move, ask about that person by name. This converts far better than a generic referral request because it is a concrete favour with a defined boundary.
Then stay in touch. A short note twice a year telling former vendors what has sold on their old street costs almost nothing and keeps you present for the decade until they move again, and for every conversation in between about which agent to use.
6. Making it a routine rather than a project
This only works if it happens after every completion without anyone deciding to do it. Build it into the file-closing process.
| Step | Owner | Timing |
|---|---|---|
| Ask vendor for price-quote consent and a review | Sales progressor | Completion day |
| Ask about a named neighbour or contact considering a move | Sales progressor | Completion day |
| Order just-sold cards for 40 to 60 addresses | Branch admin | Within 3 working days |
| Publish sold post naming street and days to offer | Whoever runs social | Within 3 working days |
| Mark listing sold on the website, keep URL live | Branch admin | Within 3 working days |
| Add vendor to the twice-yearly former-client list | Branch admin | Completion week |
An agency completing twenty sales a month is generating twenty of these cycles, which at forty to sixty addresses each puts you in front of roughly a thousand local households a month with something specific and true. Very little else in agency marketing achieves that at that cost.
Response rates in our campaigns vary widely with area density and price point, and we would rather give you the mechanism than a headline percentage that will not match your patch. Measure your own: count valuations that mention a card, over cards sent, for three months.
7. Frequently Asked Questions
Can you advertise the sold price of a property in the UK?
Once a sale is registered, the price is public via HM Land Registry and can be quoted. Before registration you need the vendor’s consent to state an exact figure, and the CAP Code requires any claim such as ‘above asking price’ to be accurate and substantiable. Quoting a band, or saying ‘sold in 11 days’, avoids most of the risk while keeping the impact.
How many neighbouring properties should a just-sold card go to?
Between 40 and 60 addresses around the sold property works better than a wider drop. The message depends on the recipient recognising the house, so relevance falls away quickly with distance. A tight, repeated drop after every completion beats an occasional postcode-wide one.
When should you ask a vendor for a referral?
At completion, not at instruction and not months later. The vendor is at peak goodwill on the day the sale finishes. Ask for something specific, a Google review, or an introduction to a named neighbour who mentioned moving, rather than a general request to spread the word.
Do sold listings help your website rank?
Yes, if you keep them. Many agency sites delete sold properties, which throws away pages that accumulate street-level relevance and links. Keep the page live, mark it clearly as sold, and it continues to attract people searching that road or development for years.
What should a just-sold social post actually say?
Name the street or immediate area, state how quickly it went, and say something specific about the outcome. ‘Sold in 9 days on Ashfield Road, three viewings, asking price achieved’ is worth more than a branded graphic reading ‘ANOTHER ONE SOLD’ because it lets a neighbour judge what yours might do.
