Rentalize vs TenantSync: An Honest Comparison
Both are Irish-built property management platforms. They serve very different customers. This page shows you which one fits your portfolio, written by Rentalize, but with an honest take on where TenantSync is the right call.
Pick the tool built for the customer you actually are.
Both platforms serve the Irish market. The right choice depends almost entirely on whether you are a private landlord with a small portfolio, or a property management company, council, or housing body with a team, a larger portfolio, or housing schemes to run.
Pick TenantSync if
You manage under 10 units as a private landlord, you mostly need RTB deadline reminders and bank reconciliation, and you want a self-serve free trial without talking to anyone. TenantSync is purpose-built for that audience.
Pick Rentalize if
You are a PMC, developer, local authority, or AHB, you manage HAP tenancies or run Affordable Purchase or Part V applicant selection, you need full audit trails for procurement, or you manage 50+ units with a team.
When TenantSync Wins. When Rentalize Wins.
We are not going to tell you Rentalize is better for everyone. It is not. Here is when each platform is the right call.
You are a solo or small Irish landlord
- You manage 1 to 10 units yourself, no team, no dedicated admin.
- Your top concern is missing an RTB deadline and getting fined.
- You bank with AIB, BOI, or Revolut and want automatic reconciliation.
- You want to sign up online for a free trial without booking a demo.
- You do not deal with HAP, affordable purchase schemes, or social housing.
You run schemes, not just rentals
- You are a PMC, developer, local authority, or AHB.
- You manage HAP tenancies, or run Affordable Purchase or Part V applicant selection. Cost Rental scheme workflows are on the roadmap, not in the product today.
- You need a supplier whose security programme is built for public procurement (ISO 27001 certification in progress, controls aligned with ISO 27018 and 27701).
- You need a full audit trail on every applicant decision.
- You manage 50 to 5,000+ units, often across multiple schemes.
- You want bank-to-bank rent collection (Rentalize Pay, with Instant Bank Pay and Direct Debit on Growth and above), not just reconciliation after the fact.

Private Irish landlords with small portfolios
TenantSync's positioning headline is "Stop Missing RTB Deadlines." That tells you exactly who they sell to. Their pricing is gated, their trial is self-serve, and their feature set is centred on RTB compliance and bank reconciliation, the things a private landlord with a few properties actually worries about. Strong content marketing through their blog has earned them top organic rankings for landlord and RTB keywords.
PMCs, developers, local authorities, AHBs
Rentalize is built for the professional end of the Irish and UK market. Property management companies with 50 to 5,000 units, developers and funds, local authorities running Affordable Purchase, and AHBs managing their housing stock. Customers are referenced (Meath CC since 2022), founders are public, and the security programme (ISO 27001 certification in progress, controls aligned with ISO 27018 and 27701) is built around the audit requirements of public sector procurement.
