Ask a portal what a seller lead costs. You'll get a number in seconds.
Ask what it's worth. Silence.
That's the enemy in this business: pricing by pain.
Most portals sell seller leads the way they learned to sell buyer leads. Fixed price per contact or subscription. It feels familiar. It's also blind.
A fixed lead price isn't calculated. It's negotiated down to what an agent can stomach. He buys five leads. None convert. It hurts, so he stops. The sixth would have closed and paid for all of them. Nobody will ever know.
The agent doesn't track his cost per lead.
The portal doesn't track what happens after the lead.
Two blind parties, one price, zero arguments.
Here's what the data says once you do track it.
People sell a home every 6–9 years. Rare event. But of everyone who runs an online valuation, about 11% start selling within the next 12 months. Not "someday". Twelve months.
In Germany a closed transaction is worth roughly €25,000 in agent commission.
So a portal is holding a contact with a known probability and a known payout, and selling it for €50 because that's where the pain threshold sits.
Success-fee pricing solves half of this. You pay only when it closes. The other half is harder: the lead has to land with an agent who actually converts. Otherwise both sides earn nothing.
The real fix is upstream. Track every property's story from first valuation to sold.
Then the lead price stops being a feeling. It becomes a number.
And in every deal where one side knows the value and the other doesn't, the one who knows wins.
Which side of that table are you sitting on?
