The verdict in three sentences
For a landlord managing 25 office buildings in Boston, a custom tenant portal costs 40,000 to 100,000 USD on the US market in 2026 (market estimate), with a timeline of 3 to 4 months. The return shows up in avoided email (30 to 40 % of inbound messages), tracked response times and tenant satisfaction at lease renewal. The first item to scope is integration with your property management software (Yardi, MRI, AppFolio), which holds leases, rent statements and charges.
What the portal must cover
The head of asset management expects four main uses, plus a lightweight mobile app for occupants.
| Function | Use | US market estimate 2026 (USD) |
|---|---|---|
| Work orders | Report with photo, category, priority, tracking to closure by the vendor | 10,000 - 24,000 |
| Tenant documents | Rent statements, invoices, CAM reconciliation, certificates of insurance | 6,000 - 14,000 |
| Room booking | Shared conference rooms, rooftop, visitor parking, calendar per building | 6,000 - 16,000 |
| News and communication | Works, outages, events, satisfaction surveys | 4,000 - 10,000 |
| Property management integration | Sync of leases, units, statements from Yardi, MRI or AppFolio | 8,000 - 20,000 |
| PWA mobile app | Install on phone, notifications, optional access badge | 6,000 - 16,000 |
A portal limited to work orders and documents starts around 40,000 USD. With bookings, PWA and full property management integration, you reach 90,000 to 100,000 USD.
How many emails and hours the portal saves
The 30 to 40 % reduction in inbound email is an order of magnitude seen in projects of this kind, provided the portal becomes the single channel for requests. The table estimates the impact for 25 buildings and about 180 tenants.
| Indicator | Before portal | After portal (estimate) |
|---|---|---|
| Inbound emails per month | 1,400 | 850 to 980 |
| Statement or certificate requests | 220 / month | 40 / month |
| Average time to acknowledge a work order | 2 to 3 days | Under 24 h |
| Work orders never closed out | 15 to 20 % | Under 5 % |
| Property manager time on email | 120 h / month | 75 h / month |
| Room bookings handled manually | 300 / month | 0 |
Recurring cost and custom versus off the shelf
Budget 800 to 2,000 USD a month for maintenance and hosting depending on document volume and user count. Yardi, MRI and tenant experience apps such as HqO or Building Engines offer ready-made portals: they are a good fit if your needs match their workflows and you accept per-building or per-square-foot pricing. Custom makes sense when work orders, bookings and per-building communication must follow your own processes and branding.
For comparison, Kolonell builds a medium-complexity custom application on its 2026 grid for 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), with maintenance at 75,000 to 120,000 FCFA per month (110 to 180 EUR).

Michael, head of asset management at a Boston office landlord (Seaport District), oversees 25 buildings and 180 tenants. His 4 property managers spend 120 hours a month on email, 45 of them resending statements, chasing vendors and handling rooms. The portal cuts that to 75 hours, saving 45 hours a month or 540 hours a year. At a loaded cost of 65 USD an hour, the gain is 35,100 USD a year. For a 75,000 USD portal and 1,400 USD a month to run it (16,800 USD a year), the net annual gain is 18,300 USD and payback comes in about 49 months. If the portal helps retain a single 5,000 square foot tenant at 70 USD per square foot per year at renewal, one year of rent, 350,000 USD, far exceeds the investment.
FAQ
How much does a tenant portal for an office landlord cost in 2026?
On the US market, 40,000 to 100,000 USD depending on modules, plus 800 to 2,000 USD a month for maintenance and hosting.
How long does launch take?
3 to 4 months. Work orders and documents can open in 3 to 5 pilot buildings after 10 weeks.
Do we need a native mobile app?
No, a PWA is enough in most cases: it installs from the browser, sends notifications and costs 6,000 to 16,000 USD instead of 40,000 USD or more for two native apps.
Can the portal connect to Yardi or MRI?
Yes, through their APIs or a daily file exchange. Budget 8,000 to 20,000 USD depending on the integration path and vendor licensing.
Do maintenance vendors use the portal too?
Yes, with dedicated access: they receive work orders for their buildings, add photos and notes, and close the job. Open-ended work orders usually drop below 5 %.
