The verdict in three sentences
A vendor CRM (USD 40-90 per user/month) equips a network fast, but the bill climbs with agent count and premium modules. A custom CRM (USD 35,000-80,000) pays off as soon as you need consolidated multi-office reporting, criteria-tuned matching and independence from a vendor. In Miami, for a 4-office network, the tipping point usually lands around the third year of operation.
The 2026 benchmark
The network pays not just for licenses but for rigidity. A vendor imposes its workflows; custom fits yours.
| Criterion | Vendor SaaS | Custom build |
|---|---|---|
| Entry cost | USD 0 to 3,000 | USD 35,000 to 80,000 |
| Monthly cost | USD 40-90/user/month | USD 350-700 (maintenance + hosting) |
| Follow-up automation | limited scenarios | unlimited, custom |
| Buyer matching | standard rules | tuned algorithm |
| Multi-office reporting | often a paid add-on | native, consolidated |
| Customization | limited fields | total |
| Vendor lock-in | strong (paid reversibility) | none, owned code |
5-year TCO: the real trade-off
Five-year total cost reveals the difference. Take a 14-user network in Miami.
| Year | Vendor (14 users x USD 70) | Custom (USD 60,000 + USD 5,000/yr) |
|---|---|---|
| Year 1 | USD 11,760 | USD 65,000 |
| Year 2 | USD 11,760 | USD 5,000 |
| Year 3 | USD 11,760 | USD 5,000 |
| Year 4 | USD 11,760 | USD 5,000 |
| Year 5 | USD 11,760 | USD 5,000 |
| 5-year total | USD 58,800 | USD 85,000 |
At constant volume, the vendor stays cheaper in pure cash over five years. But custom wins as the network grows (each new user is free) and on the value of automations that generate revenue.

Mini case study
Sofia, director of a 4-office network in Miami, employs 16 agents. On a vendor she pays 16 x USD 75 x 12 = USD 14,400/year, plus USD 3,000 in reporting add-ons, totaling USD 17,400/year. She moves to custom at USD 68,000 with USD 5,500/year maintenance. The bet: automating follow-ups lifts lead conversion from 8% to 11%. On 900 leads/year at USD 4,800 average fees, those 3 points mean about 27 extra conversions, i.e. USD 129,600 in added revenue: the investment is absorbed in under a year.
FAQ
At what size does custom make sense? Generally beyond 12-15 users, or as soon as consolidated multi-office reporting and specific automations become strategic.
How long to build a custom real estate CRM? Expect 12 to 20 weeks depending on modules (follow-ups, matching, reporting, buyer portal) and integrations.
What about vendor lock-in? It disappears. You own the code and the data, with no imposed price hikes or reversibility fees.
Can data be migrated from my current vendor? Yes, a data migration (contacts, mandates, history) is planned in the project and tested before go-live.
Is custom riskier? Risk is managed with serious scoping, an MVP delivered in weeks and sprints. A vendor carries a different risk: never fitting your processes.
