The verdict in three sentences
A housing provider with 3,000 homes handling 40,000 calls a year can remove about 30% of them with a portal where tenants view rent statements, download receipts and track repair requests. A realistic budget is 40,000 to 90,000 EUR, plus 10,000 to 25,000 EUR to integrate the property management system. Integration is what makes or breaks the project: without it, the portal shows stale data and the calls come back.
Why tenants call, and what the portal absorbs
The head of housing management knows the call mix. On average, 60% concern three simple topics a portal handles better than an advisor on the phone.
| Call reason (2026 order of magnitude) | Share of calls | Calls per year | Share avoidable via portal | Calls avoided |
|---|---|---|---|---|
| Follow-up on an existing repair request | 28% | 11,200 | 50% | 5,600 |
| New repair request (leak, heating, lift) | 22% | 8,800 | 25% | 2,200 |
| Balance, rent statement, receipt | 18% | 7,200 | 45% | 3,240 |
| Certificates (benefits, insurance) | 8% | 3,200 | 40% | 1,280 |
| Contact or bank detail changes | 6% | 2,400 | 30% | 720 |
| Neighbour disputes, sensitive matters | 18% | 7,200 | 0% | 0 |
| Total | 100% | 40,000 | 13,040, about 30% |
Sensitive matters stay on the phone, which is desirable: freed-up advisors can give them more time.
The budget line by line
| Module | Function | Budget (excl. VAT) |
|---|---|---|
| Secure tenant area | Sign-up, authentication, profile, joint tenants | 6,000 to 12,000 EUR |
| Rent statements and receipts | View, PDF download, 36 month history | 5,000 to 10,000 EUR |
| Repair requests | Guided form by equipment, photos, status tracking | 10,000 to 22,000 EUR |
| Notifications | SMS and email at each request stage | 3,000 to 7,000 EUR |
| Housing officer back office | Triage, contractor assignment, deadlines | 8,000 to 20,000 EUR |
| Accessibility (WCAG) and mobile | Screen readers, large text, mobile first | 4,000 to 9,000 EUR |
| Reporting | Handling times, reasons, satisfaction | 4,000 to 10,000 EUR |
| Property management system integration | Sync leases, accounts, repairs | 10,000 to 25,000 EUR |
Then budget 800 to 2,000 EUR per month for hosting, maintenance and SMS. Delivery takes 4 to 7 months depending on your management system's API.
Three conditions for success
First: sync data at least daily, otherwise tenants see a wrong balance and call. Second: show the real status of each repair (received, sent to contractor, appointment set, closed) with a date. Third: drive adoption with a letter carrying an activation code, office drop-in sessions and support from caretakers. An adoption rate of 45 to 60% after one year is realistic.
Mini case study
Catherine heads housing management for a 3,000-home provider. Her contact centre handles 40,000 calls a year at an estimated full cost of 5 EUR per call (5 advisor minutes, software, supervision), or 200,000 EUR per year. She invests 68,000 EUR in the portal, including 18,000 EUR of integration, plus 1,200 EUR per month. After 18 months, calls drop by 30%: 12,000 fewer calls, worth 60,000 EUR per year. Net of 14,400 EUR annual running costs, the gain reaches 45,600 EUR per year: the portal pays back in about 18 months.

FAQ
How much does a tenant portal for 3,000 homes cost?
Between 40,000 and 90,000 EUR to build, plus 10,000 to 25,000 EUR to integrate the property management system and 800 to 2,000 EUR per month to run.
Can calls really drop by 30%?
It is an achievable order of magnitude if repair tracking is real time. Without reliable status, the drop often caps at 10 to 15%.
Will older tenants use it?
Some will not, and the phone line must stay open. An accessible interface, large text and caretaker support bring adoption to 45 to 60% within a year.
Mobile app or website?
A responsive website, installable as a PWA, is enough in most cases. A native app would cost 20,000 to 40,000 EUR more with no proven adoption gain.
Does the property management system have an API?
Most major systems offer one, sometimes billed 2,000 to 8,000 EUR per year by the vendor. Check this before pricing the project.
