US: selling a $15M ultra-luxury property
US
Situation: A brokerage represents a $15M residential property. The goal is a closed sale, but the sale price is not the brokerage's revenue. In the reference model, a 3% total commission of $450,000 leaves $225,000 for the brokerage at a 50% retention share, and about $200,000 in contribution after $25,000 of closing and service costs.
Why generic ads are not enough: A trophy asset has very few qualified buyers. Generic Google or Meta lead campaigns cannot be claimed to sell such a property on their own, and US housing rules restrict age, gender and ZIP targeting. The realistic journey runs through qualified buyer meetings, authorised brokers and private viewings.
Blueprint outline
- Model economics on retained contribution: with 20% of contribution permitted for marketing, the example maximum all-in CAC is $40,000 per closed sale
- At an assumed 4% qualified-buyer-to-sale rate, the example permissible cost per qualified buyer lead is $1,600 and about 25 qualified leads are needed per expected sale
- Luxury microsite or private sales room with consented enquiry handling
- Search intent campaigns, direct premium publisher placements and curated CTV as candidates
- Authorised broker network and concierge follow-up as non-media channels
- CRM stages: qualified buyer meeting, verified offer, closed sale
Media versus partner channels: Media candidates: search, premium publishers bought direct, curated CTV and contextual programmatic. Partner and outreach channels: authorised brokers, private networks and concierge, which are not advertising platforms and are planned and costed separately.
Measurement: Qualified buyer meetings, verified offers and closed sale in the CRM. Platform conversions are shown only as platform-reported events.
Limitations: All percentages are example assumptions from the reference workbook. A probabilistic expected sale is not a forecast or a guarantee. Broker licensing, fair housing rules and the absence of personal wealth profiling must be confirmed.
