The verdict in three sentences
For a Miami real estate agency wanting to run CRM, listings and multi-portal syndication, custom software costs between 45,000 and 100,000 EUR in 2026, delivered in 4 to 7 months. Real estate SaaS (50-200 EUR/agent/month) is ideal to start, but its per-agent cost becomes punishing as the team grows. The tipping point usually sits around 10-12 agents over a 5-year horizon.
Key features and 2026 costs
The core of an agency is the CRM linked to listings, automatic syndication to portals (MLS, Zillow-style feeds) and smart buyer/property matching.
| Module | Scope | Indicative 2026 cost (EUR) | Timeline |
|---|---|---|---|
| CRM & prospecting | Contacts, history, tasks | 8,000 - 16,000 | 3-5 wk |
| Listings/mandates | Sale, rental, legal tracking | 7,000 - 15,000 | 3-5 wk |
| Multi-portal syndication | MLS, portals, XML feeds | 9,000 - 20,000 | 4-6 wk |
| Buyer matching | Property/criteria matching | 8,000 - 17,000 | 4-6 wk |
| Public site + client area | Search, alerts, bookings | 7,000 - 15,000 | 3-5 wk |
| Core + integrations | Auth, roles, accounting, e-sign | 10,000 - 24,000 | 5-7 wk |
Add maintenance of 1,200 to 3,000 EUR/month depending on agent count and connected portals.
Build vs buy over 5 years by agency size
SaaS bills per agent: the bigger you grow, the wider the gap. Here is a 2026 5-year projection, base 120 EUR/agent/month on the SaaS side.
| Agents | SaaS 5 years | Custom 5 years* | Best choice |
|---|---|---|---|
| 5 agents | 36,000 EUR | 110,000 EUR | SaaS |
| 10 agents | 72,000 EUR | 120,000 EUR | SaaS/tie |
| 15 agents | 108,000 EUR | 130,000 EUR | Compare |
| 25 agents | 180,000 EUR | 145,000 EUR | Custom |
| 40 agents | 288,000 EUR | 160,000 EUR | Custom |
*Custom = initial build (45,000-100,000 EUR) + cumulative maintenance. Custom cost is near-fixed regardless of agent count.

Mini case study
Laurent, principal of a 22-agent agency in Miami, pays 22 x 130 EUR = 2,860 EUR/month on SaaS, i.e. 34,320 EUR/year and 171,600 EUR over 5 years. Custom software at 88,000 EUR + 2,000 EUR/month maintenance comes to 208,000 EUR over 5 years... but with no surcharge per new agent. From the 26th hire, custom pulls ahead, and automated buyer/property matching adds roughly 6 to 8 extra sales/year, a commission gain far above the cost gap.
