Open your last appraisal and find the marketing allowance.
Not the agent’s selling fee. The marketing.
For most developers it’s one of two things. A round number that got typed in early and never questioned again, or a gap where the number should be, because marketing is something you’ll deal with properly once the roof is on and you can see what’s left.
Every other figure in that document has been fought over. The build cost has been priced three times, the contingency has been argued down and then argued back up again a fortnight later, and somebody has been to the broker twice about the finance. Then there’s marketing, sitting near the bottom, treated as the one number everyone would like to make smaller.
Which is odd, because it’s one of the few things in the whole appraisal that gives money back.
Nobody asks a QS to cut the contingency to zero
The mistake here isn’t really about marketing. It’s about which column things sit in.
Some costs in an appraisal consume money and some protect it. Contingency does nothing at all if the job runs cleanly, and saves the scheme if it doesn’t, which is why nobody stands over a QS demanding it be stripped out on the basis that everything will probably be fine. Site insurance works the same way. You don’t argue the premium down because the site probably won’t flood.
Marketing belongs in that second column for exactly the same reason. It exists to reduce the likelihood and the cost of the thing that actually goes wrong on developments, which is almost never the build. It’s the sale.
And yet it gets treated as discretionary, as though a development that nobody has heard of will sell at the same speed and the same price as one people have been waiting for. It won’t, and every developer who has stood in an empty show home in month four already knows it.
The money isn't coming out of your pocket anyway
This is the part that changes the conversation, and most developers have simply never had it put to them plainly.
Marketing and sales costs are a legitimate part of a development appraisal. They sit alongside professional fees, contingency and finance, they get drawn down like everything else, and lenders expect to see them. The money is funded within the facility. It is not money you scrape together from somewhere else when the scheme is already three months past practical completion and going nowhere.
An underwriter reading an appraisal with no marketing allowance in it draws the obvious conclusion, and it isn’t that you’re commercially disciplined. It’s that nobody has thought seriously about how these units are going to sell, which makes the exit look like something you’re hoping for rather than something you’ve planned.
So the developers who genuinely feel the pain of marketing spend are, almost without exception, the ones who left it out at the start. They went to market with a planning reference for a name and a brochure knocked up in an afternoon, watched the scheme stall, and then paid for a rescue job out of their own margin at the worst possible moment. That version does hurt. It hurts because it was late, unbudgeted and reactive, not because marketing is expensive.
The costly thing on your scheme was never the marketing. It was the calendar.
Development finance is not cheap and was never designed to be. It’s short, secured, priced for risk, and it rolls up in the background while you’re dealing with something else. There’s an exit fee waiting at the end, an extension fee if you need one, and a lender forming a view about whether you’re the sort of developer who needs to ask.
Every month a finished unit sits unsold, that meter runs, and it doesn’t run gently. It runs on the whole facility, not on the one unit. Add the site security, the council tax, the insurance and the growing tone in your monitoring surveyor’s reports, and the cost of a slow sales period stops being an inconvenience and becomes the difference between a good scheme and an average one.
Development finance sits well above the Bank of England’s Bank Rate, and it has done for some time. So put the two things next to each other and ask a slightly different question. If a properly branded scheme, launched early, with people already on a list before the scaffolding comes down, pulls your sales period forward by two months, what has that saved you in finance alone?
More than the marketing cost. Usually by a distance that makes the original debate look faintly ridiculous.
That isn’t a marketing argument. It’s an appraisal argument, and it’s the one worth having with whoever is telling you the number is too high.
Lenders don't fund schemes. They fund exits.
Everything a lender does is an assessment of how confidently you’ll repay them and when. Their uncertainty is expensive, and you pay for it in rate, in loan to value, in personal guarantees, and in how long the credit committee takes to come back to you.
A development with a real name, a real story and demonstrable demand answers that question before it’s asked. Reservations taken before practical completion aren’t just early income. They’re evidence, and evidence is the only currency that actually moves a lender. They tell an underwriter that the market has already voted and that the figure in the valuation report isn’t theoretical.
That does three things at once. It de-risks the facility you’re in, it strengthens your position on the next one, and it hands you the thing most developers on their second or third scheme are missing, which is a track record they can actually show somebody.
Marketing, done at the right point rather than the last point, is how that evidence gets manufactured.
What this actually costs you
Here’s what happens on a scheme that arrives with no positioning behind it.
The build finishes, the units go up on the portals, and they look like every other new build within ten miles, because nothing was ever done to make them feel like anything else. Interest is polite. Viewings are slow. And then, somewhere around week nine, the agent starts using the phrase “adjusting expectations”, which is the property industry’s way of telling you to prepare for the conversation you’ve been dreading.
Then the discounting starts, and a reduction across even a handful of units will cost you several times over what a proper brand, a proper microsite and a proper set of assets would have cost at the outset. It is the most expensive decision available to a developer, and it is nearly always the direct consequence of the cheapest decision they made a year earlier.
People don’t buy a home with a spreadsheet. They buy on a feeling and justify it afterwards with the spec, which is why a scheme with a name, a character and a story people want to repeat doesn’t get compared like for like against the anonymous one down the road. It gets judged on its own terms, and it holds its price.
What to actually do about it
Put the number in the appraisal at the start, before the scheme is bought, so it’s funded rather than found. Treat it as part of the exit strategy, because that’s what it is.
Get the positioning and the name sorted before anyone touches a logo. Who is this scheme genuinely for, what do they want that it delivers better than the alternatives, and what should they remember about it. Those answers make every downstream decision easier and cheaper.
Start being visible during the build rather than at the end of it. A development that people discover over six months arrives with an audience. One that gets announced arrives with strangers.
Make sure the assets match the price you’re asking, because a mismatch between the two creates doubt faster than anything else, and doubt is what discounts are made of.
Then judge the whole thing on the right measure. Not impressions, not engagement, but reservations taken and months of finance saved. That’s the only scorecard that matters here.
Final thoughts
The question “how much does it cost to market a property development” takes for granted that the money leaves and doesn’t come back. On a scheme that’s been planned properly, it never leaves at all. It’s drawn from a facility you’re already paying for, and it goes to work reducing the two most expensive things in development, which are time and uncertainty.
There is one honest caveat and it matters. This only holds if it’s done early and done well. Bolted on at practical completion, with a name lifted from the planning reference and a brochure that reads like a planning statement, it will cost you money and return nothing. That isn’t marketing. It’s admin with a design budget.
So here’s the question worth sitting with. If your scheme completes and the units sit for four months longer than your appraisal assumed, what does that cost you, and what would you have been willing to spend at the start to avoid it?
If you’re not sure, that’s the place to start.
