The verdict in three sentences
A real estate SaaS is hard to beat to launch fast at 60-250 EUR/month per agent, but every new hire inflates a bill you never capitalize. A custom platform at 45,000-110,000 EUR bundles transactions, rental management, a marketing site and portal syndication into an asset you own. The tipping point sits around 8-12 agents, or when your workflow outgrows the market's standard mold.
Market SaaS vs custom platform: the numbers
SaaS bills per seat: past a certain size, the monthly total exceeds amortizing a proprietary build. 2026 order of magnitude:
| Item | Real estate SaaS | Custom platform |
|---|---|---|
| Entry cost | 0-1,500 EUR setup | 45,000-110,000 EUR |
| Recurring | 60-250 EUR/mo per agent | Maintenance 12-16 %/yr |
| Portal syndication | Included (limited) | Connector 4,000-10,000 EUR |
| E-signature | Add-on 15-40 EUR/mo | Integration 2,500-6,000 EUR |
| Workflow customization | Low | Full |
| Code ownership | No | Yes |
| Time to launch | 1-4 weeks | 4-6 months |
For a 10-agent brokerage, SaaS at 150 EUR/month per seat is 18,000 EUR/year, i.e. ~90,000 EUR over 5 years with no balance-sheet asset.
The modules that make the difference
A custom platform's value lies in end-to-end integration: enter a listing once, syndicate everywhere. 2026 lot estimates:
| Module | Range (EUR) | Operational gain |
|---|---|---|
| Transaction core + CRM | 20,000-45,000 | Single client/property base |
| Rental management + receipts | 12,000-30,000 | Automated rent notices |
| Portal connector | 4,000-10,000 | -25 to -40 % re-entry |
| Lease e-signature | 2,500-6,000 | Remote-signed leases |
| Marketing site + search | 8,000-18,000 | Direct lead generation |
| Mobile agent app | 12,000-25,000 | Field entry, photos |
Mini case study
Thomas runs an 11-agent brokerage in Miami. On SaaS at 160 EUR/month per seat he pays 21,120 EUR/year. He commissions a custom platform at 82,000 EUR (transactions, rental management, portal connector, e-signature). Maintenance at 14 % is 11,480 EUR/year. Removing double data entry (-35 % admin time, ~0.4 FTE saved at ~28,000 EUR loaded/year, about 11,200 EUR gained), the custom build turns cash-neutral around year 4, then yields an owned asset and net margins after.

What does custom real estate software really cost in 2026?
Expect 45,000-110,000 EUR depending on modules, plus 12-16 %/yr maintenance. A transaction + rental + syndication project typically lands around 70,000-90,000 EUR.
Is custom worth it for a small brokerage?
Below 6-8 agents, SaaS is usually cheaper. Custom is justified by size, an atypical workflow, or a strong brand strategy.
Can I syndicate to portals from an in-house platform?
Yes, via a feed connector (usually XML/partner APIs) costing 4,000-10,000 EUR. Verify diffuser-account eligibility with each portal first.
How long until we're operational?
Expect 4-6 months for a first version covering transactions and rental management, with a gradual migration of existing data.
Does an e-signed lease hold legal value?
Yes, with a qualified eIDAS provider. Integration costs 2,500-6,000 EUR and eliminates paper back-and-forth.
