Qualify property buyers before cutting CPM
A premium development can buy cheap impressions and cheap leads all day and still sell nothing. The buyers who matter are few, and in the US the rules for housing ads take away the demographic and ZIP code shortcuts that might otherwise narrow the audience. That puts the work in qualification: what the enquiry form asks, how fast sales calls back, which leads are passed back to the ad platforms as qualified, and what each qualified viewing is worth. Optimise the campaign towards that signal. Lower CPM is only useful once the qualified-viewing rate is known.
Executive findings
- 1
Google’s personalised advertising policy restricts housing ads in the United States and Canada: age, gender, marital status and parental status may not be targeted, and ZIP code targeting is not allowed. Radius targeting of at least 1 km and city targeting remain available.
Documented: official source. Scope: Google Advertising Policies Help, restricted targeting, as of . [1]
- 2
Meta requires housing, employment and financial products campaigns to declare a Special Ad Category; some demographic, behaviour and interest options are then unavailable, detailed-targeting exclusions cannot be used, and Advantage+ lookalike is unavailable.
Documented: official source. Scope: Meta Business Help Center page on Special Ad Category audiences, as of . [2]
- 3
HUD states that the Fair Housing Act prohibits discrimination in housing, including advertising, because of race, colour, national origin, religion, sex, familial status and disability.

In our illustrative model, halving cost per lead doubles leads but raises the cost per qualified viewing when the qualified share falls from 8% to 3%.

Method and limitations
- Question
- In high-ticket residential sales, should a campaign optimise first for lower media cost or for a defined qualified buyer?
- Written for
- Sales and marketing directors at property developers and premium brokerages, and their finance leads.
- Decision at stake
- What to optimise the next campaign towards, and what data the sales team must return to make that possible.
- Sources
- Google and Meta advertising policies on housing ads, HUD material on the Fair Housing Act, and the 2022 Justice Department settlement with Meta on housing ad delivery.
- Period
- Policies and official pages as published on 17 October 2026.
- Markets
- United States, with notes for Canada where Google’s rule also applies. Other markets have their own rules; Saudi Arabia and the UAE are covered by local regulators, not these policies.
- Definitions
- Qualified viewing: a booked viewing with a buyer who meets the developer’s written criteria (budget, timing, financing or proof of funds).
- Qualified share: qualified viewings divided by all leads.
- Cost per qualified viewing: media cost divided by qualified viewings.
- Limitations
- We read Meta’s Help Center text through a search index because the page refused automated access on the date of review; check the live page before relying on it.
- This is not legal advice. Housing advertising rules also exist at state and local level.
- We publish no CPM, CPL or conversion benchmarks for property; they vary by city, price band and season.
The rules narrow targeting on purpose
Documented: official source
US housing ads cannot be aimed at people by age, gender, family status or ZIP code on Google, and Meta removes comparable options under its Special Ad Category. These rules follow the Fair Housing Act and, in Meta’s case, a 2022 settlement with the Justice Department over how housing ads were delivered.
The practical effect is that audience settings do less of the work. A campaign for a 2 million apartment reaches a broad audience inside the allowed geography, and the job of separating buyers from browsers moves to the creative, the offer and the follow-up.
Where qualification can happen lawfully
FOCUSADS view
Creative and copy can state the price band and the purchase process plainly, which lets unsuitable visitors leave early. The enquiry form can ask about timing, financing and preferred unit type, questions about the purchase, not about protected characteristics. Sales can call back quickly and record the outcome in the CRM. Passing qualified viewings back to the ad platforms as conversions lets their bidding learn from the outcome the business cares about.
Check every form question and every audience list with counsel familiar with fair housing rules. Asking about budget and timing is ordinary sales practice; filtering by protected characteristics is not allowed.
Worked model: cheaper media, fewer qualified buyers
Illustrative model, not a benchmark
Two versions of the same monthly campaign spend 20,000. Version B uses broader placements that halve the cost per lead.
| Line | Version A | Version B | How it is calculated |
|---|---|---|---|
| Media spend | 20,000 | 20,000 | Assumption |
| Cost per lead | 100 | 50 | Assumption |
| Leads | 200 | 400 | Spend ÷ cost per lead |
| Qualified share | 8% | 3% | Assumption, from CRM outcomes |
| Qualified viewings | 16 | 12 | Leads × qualified share |
| Cost per qualified viewing | 1,250 | 1,667 | Spend ÷ qualified viewings, rounded |
Assumptions
- All figures are placeholders; use your CRM outcomes.
- Version B also costs more sales time: 400 leads to call instead of 200.
- The model assumes the same close rate from a qualified viewing in both versions.
What we would test, in order
| Step | Measured by | Counts as success when |
|---|---|---|
| Write the qualified-viewing definition with sales and add the matching questions to the enquiry form. | Share of leads with every qualification field completed. | At least 90% of leads carry the fields within two weeks. |
| Import qualified viewings back into Google Ads and Meta as the primary conversion. | Qualified viewings recorded in each platform against the CRM. | Platform and CRM counts match within 10%. |
| Only then test lower-cost placements, judging them on cost per qualified viewing. | Cost per qualified viewing by placement. | Keep a placement only if cost per qualified viewing falls. |
Before you optimise for cheaper media
If any answer is no, fix it before touching CPM or CPL targets.
| Question | Why it matters |
|---|---|
| Is the housing Special Ad Category or restricted targeting set correctly? | Campaigns can be rejected or breach fair housing rules |
| Is there a written qualified-viewing definition? | Without it, optimisation has no target |
| Does the form capture budget, timing and financing? | Qualification moves from targeting to the form |
| Are qualified viewings imported back into the platforms? | Bidding learns from leads, not from buyers, otherwise |
| Does sales call back within an agreed time? | Slow follow-up lowers the qualified share regardless of media |
How this connects to our method: Build the conversion infrastructure first
