Your website already has the traffic, the search function and the audience. With a payment function on top, other agents, landlords and developers can list their properties on it, and pay you for the privilege. Here is how that works, what to charge for, and why the timing has rarely been better.
Most estate agency websites do one job. They show that agency’s own listings, and when a visitor has seen them all, the visit is over.
A platform does something different. It shows listings from many parties, which means there is always something new, which means visitors come back, which means the listings are worth more, which means more parties want to be on it. That loop is the entire business model of every property portal in Europe, and there is nothing about it that only works at national scale.
A well-run regional or specialist platform can work beautifully. And you may be closer to having one than you think.
Why now, specifically
Portal costs are climbing, and agents are noticing.
In the Netherlands, Funda announced a new pricing structure starting in September, with three advertising packages where the gold tier is set at 536 euro. Nineteen of the twenty-seven regional NVM departments signed a letter demanding the increases be scrapped, calling them disproportionate.
Whatever the outcome of that particular dispute, it tells you something useful: agents are actively looking at what they pay for visibility and asking whether there are alternatives. That is a rare moment, and it is exactly when a well-priced local platform becomes interesting to the colleague down the road.
You do not need to compete with a national portal. You need to be a sensible second channel at a fair price, in a region or a niche you already understand.
Who would actually pay to be on your site
More parties than you might assume.
Other estate agents, particularly smaller offices without the budget or the traffic to build their own audience. For them, your platform is cheaper visibility with a colleague they already know.
Agencies in neighbouring regions who want exposure in your area without opening an office there. This is often the easiest first group to approach, because you are not direct competitors.
Landlords and property managers with a steady supply of rentals, who want a simpler route to tenants.
Property developers with new-build projects, who typically have a marketing budget and a fixed period in which they need attention.
Private sellers, if you want to open the platform beyond professionals.
And adjacent businesses, which people forget entirely. Mortgage advisors, notaries, surveyors, photographers, stylists, removal companies and contractors all want to be in front of someone who is moving house. A banner or a directory listing on a site with genuine property traffic is a real product.
What you can charge for
There are three models, and the strongest platforms run all three at once.
Recurring membership packages. A professional pays a monthly or yearly fee to list on your platform, usually with a limit on how many properties. This is the foundation, because it is predictable income that arrives without an invoice, a reminder or a conversation.
Pay per listing. A one-off fee for each property submitted. This suits occasional advertisers, private sellers and anyone unwilling to commit to a subscription. It is also the easiest way to let someone try the platform.
Featured and upgraded placement. The same product the big portals sell. A listing at the top of the results, highlighted in the search, or shown on the homepage. This is where the margin is, because it costs you nothing to deliver and the advertiser is buying attention rather than access.
You can combine them freely. A common structure is a modest monthly package for access, with featured placement sold separately when someone has a property they need to move quickly.
The benefits that are not the subscription fee
The direct revenue is the obvious part. The indirect effects are often worth more.
More supply makes your site more useful. A visitor who finds twenty relevant properties instead of four stays longer, returns more often and is more likely to remember where they found them.
More traffic makes your own listings perform better. Every property you advertise for someone else brings visitors who also see yours.
Collaboration becomes natural. Once other agents are on your platform, you are in regular professional contact with them. That leads to referrals in both directions, shared viewings, and the kind of relationships that produce instructions you would never otherwise have heard about.
Referral and introduction arrangements become possible. If a buyer arrives through your platform and transacts with another agent, that is a conversation about a fee worth having. Get the arrangement in writing before you need it.
And you build an audience that belongs to you. Whatever any portal does with its pricing next year, your platform and the relationships on it stay yours.
The bit that used to be hard
The reason most agencies never did this is that the machinery was daunting. You needed a way for other parties to submit and manage their own listings without access to your admin, a way to limit what each package allowed, a way to charge them, and a way to make renewals happen without you chasing anyone.
That is a lot of software. It is also, as it happens, exactly what the Houzez theme already does.
Houzez includes frontend submission, so an advertiser logs in at the front of your site, submits their own property, uploads their own photos and manages their own listings. You never touch it. It includes membership packages with limits and durations, so a package can allow five active listings for a month and then expire. And it includes featured listings as a paid upgrade.
What Houzez does not include is European payment breadth. It supports Stripe and PayPal for these payments out of the box, and its own documentation notes that recurring billing works only with those two gateways. For a Dutch or Belgian advertiser, that is the wrong list. They want iDEAL or Bancontact.
Making the money side work
Mollie for Houzez adds that layer as a single plugin. It connects your site to Mollie and puts payments into the checkout Houzez already has, with 30 payment methods including iDEAL, Bancontact, cards, Apple Pay, Google Pay and SEPA Direct Debit. You choose which appear.
For a platform, three things matter most.
Recurring memberships are handled by the plugin itself, so a monthly or yearly advertising package renews automatically without a separate subscriptions extension and without WooCommerce underneath your site. Your advertiser pays once and stays on. You stop invoicing.
Advertisers can cancel themselves from their dashboard, keeping access until the end of the period they paid for. That sounds like a concession, but it is what makes professionals willing to start in the first place.
And the administration is automatic. Invoices go out in your name, refunds are issued from your own WordPress admin, and the analytics show revenue over time, one-time against recurring income, active subscribers and churn. For anyone running a platform, churn is the number that tells you whether your packages are priced right.
If you also want to invoice an advertiser for something arranged off the website, payment links with a QR code and an invoice are included on the Business and Agency tiers.
How we would start
Do not build a portal. Start a pilot.
Approach three to five agents you already have a decent relationship with, ideally from a neighbouring area so you are not competing directly. Offer them a genuinely fair introductory package for six months. Make the deal easy to say yes to and easy to leave.
Set your package limits deliberately. A package that allows unlimited listings sounds generous and usually attracts the wrong advertiser. A package that allows five active listings keeps quality up and gives you a natural upsell.
Turn on listing approval so nothing appears on your site that you have not seen. Your reputation is the product here.
And price the featured upgrade separately from the start. It is the easiest revenue you will ever add, and advertisers expect it to exist.
Then give it a season. Platforms compound: the second advertiser is easier to sign than the first, and the tenth is easier than the second, because by then the traffic argument makes itself.
The point is not to become a portal. It is to stop being only a brochure, and to own a channel that other people pay to be part of.

Frequently asked questions
Can I let other agents advertise on my own website?
Yes. The Houzez theme includes frontend submission, membership packages and featured listings, so other parties can submit and manage their own properties. Adding a payment plugin lets you charge for it and have those packages renew automatically.
How should I price advertising packages?
Most platforms combine a recurring membership for access, a pay-per-listing option for occasional advertisers, and a separately priced featured or highlighted placement. Set a limit on active listings per package rather than offering unlimited.
Do advertisers get access to my WordPress admin?
No. Frontend submission means they log in at the front of your site and manage only their own listings. You can also require approval before anything is published.
Which payment methods should I offer advertisers?
For Dutch and Belgian professionals, iDEAL and Bancontact first, with SEPA Direct Debit behind recurring packages. Cards, Apple Pay and Google Pay cover international advertisers.
Do I need WooCommerce to charge for listings?
No. Mollie for Houzez adds payments to the Houzez checkout directly, as a single plugin, with recurring memberships handled natively.
What do I need to run it?
The Houzez theme 4.x, WordPress 6.0 or higher, PHP 8.1 or higher, a free Mollie account, and a site on HTTPS.
