Two rental management tools in Spain, compared without marketing fluff: 18 dimensions, real pricing and when to pick each.
Updated October 2026, based on publicly available information on rentger.com.
In short
For a private investor with 1 to 25 flats in Spain, imotrack is the more complete choice: your portfolio inside Claude and ChatGPT, Imo on WhatsApp, Spanish tax ready for Modelo 100 or 210 and the real return of every flat. If you are an agency, imotrack Pro adds owner statements, leases with e-signature and teamwork. Rentger by Idealista fits better if your priority is maintenance ticketing or the Idealista ecosystem.

What each actually costs in 2026.
Rentger by Idealista
€0 to €10.80/month
Its pricing page shows a free plan up to 9 properties and per-property rates from €3 to €10.80/month depending on volume and yearly or monthly billing (checked October 2026).
imotrack
From €4.90/month
Starter at €4.90/month for 1 property, Investor at €14/month for up to 5 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".
E-signature is available in imotrack Pro, the plan for agencies. For investors there is no built-in signing and no maintenance ticketing with contractors. If you need them today, Rentger is the better fit on that point.
It depends on what you need. If you want maintenance ticketing, the Idealista integration or the defaulter database, Rentger covers that. If your priority is tax and the real return of each flat, imotrack saves you more time: a 30-day free trial, then from €4.90/month.
imotrack imports your spreadsheet or CSV as it is: AI recognises the columns and you review before saving. Rentger offers its own export. For a 5 to 20 flat portfolio, migration takes one or two hours. For larger portfolios, the imotrack team can help case by case.
imotrack. Its tax export automatically splits residents (Modelo 100, with each lease's reduction) and non-residents (Modelo 210: 19% on net income for EU/EEA residents, 24% on gross otherwise). With generic accounting software, you or your adviser make that split by hand.
Not 100% objective, obviously. But it's honest: we flag the dimensions where Rentger is clearly better (maintenance, Idealista ecosystem, digital signing for investors) without hiding them, and we tell you when to pick it. To validate via third parties, check Rentger's reviews on Trustpilot and Capterra, and try imotrack with your own flats.
Yes, with imotrack Pro, the plan for agencies: a portfolio shared by your team with per-person permissions, a monthly statement for each owner with fees and VAT, lease templates with e-signature and import of your spreadsheets. It costs €99/month for up to 100 properties. Rentger remains the better fit if you need maintenance ticketing with contractors or the Idealista integration.
No credit card, no commitment. If it doesn't fit after 30 days, switch to Rentger or go back to your spreadsheet. But try ours first, especially for the tax side.
