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 mostly on whether you are a landlord or smaller agency that wants a low published price and a self-serve trial, or a property management company, council, or housing body with a team, a larger portfolio, or housing schemes to run.
Pick TenantSync if
You are a landlord or an agency with up to about 300 units, you mostly need RTB compliance and Open Banking rent matching, and you want a self-serve free trial without talking to anyone. TenantSync's published plans suit that buyer.
Pick Rentalize if
You are a PMC, developer, local authority, or AHB, you manage HAP tenancies or run Affordable Purchase 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 landlord or smaller agency
- You want a low published monthly price: TenantSync lists plans from €20 (up to 10 units) to €199 (agencies up to 300 units).
- 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 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.
