The two serious rental management SaaS in Spain, compared without marketing fluff. 15 dimensions, real pricing, when to pick which and why.
Updated May 2026, based on publicly available info on rentger.com.
In short
If you manage flats with a generalist professional approach (maintenance, listings, basic bookkeeping), Rentger by Idealista is probably the better fit, especially if you want to plug into the Idealista ecosystem. If you're a private investor with 1 to 20 flats in Spain and you prioritise sharp Spanish fiscality (Modelo 100/210), AI for contracts and real yield analysis (cash-on-cash, ROI), imotrack is built for you.
No "best at everything", just what each tool does well or poorly.

What each actually costs in 2026.
Rentger by Idealista
€0 / €3.75 per month
Free up to 9 flats, then €3.75/month per asset (or €36/year, 20% savings).
imotrack
From €0
Free forever with 1 property. Investor plan at €14/month for up to 5 properties and Premium at €29/month for up to 25.
Yes. Rentger was acquired by Idealista in January 2021 and integrated into their professional product catalog. That's why their official communications go out as "Rentger by idealista".
Yes. Maintenance ticketing and digital signing are on the roadmap for Q3 2026. If they are critical to you today, Rentger is the better short-term fit, and you can try imotrack when those features land.
It depends. If you need the features imotrack lacks (maintenance, Idealista integration, defaulter DB), paying €3.75/month per flat is more than worth it. If your priority is fiscality + yield analysis, imotrack gives you more for less: free with 1 property and from €14/month after that.
imotrack supports CSV import (flats, contracts, income). Rentger offers its own export. Manual migration isn't instant but is feasible for a mid-size portfolio (5-20 flats) in 1-2 hours. For larger portfolios, the imotrack team can help case by case.
imotrack, hands down. Its tax export automatically splits residents (Modelo 100 with the 60% reduction) and non-residents (Modelo 210, EU 19% on net or extra-EU 24% on gross). Rentger doesn't explicitly differentiate between the two tax profiles.
Not 100% objective, obviously. But it's honest: we flag the dimensions where Rentger is clearly better (maintenance, Idealista ecosystem, digital signing) without hiding them, and we tell you when to pick them. To validate via third parties, check Rentger's reviews on Trustpilot and Capterra, and ask us for a demo to validate imotrack in your specific case.
No credit card, no commitment. If it doesn't fit after 30 days, switch to Rentger or stay on Excel. But try ours first, especially for the tax side.
