We recently ventured into real estate and property management in Germany. Our current portfolio consists of two adjacent apartment buildings with a total of 30 units. Since we're still in the setup phase, we're scrutinizing every expense, and we started looking into free property management software to keep our fixed overhead low.
Searching online turns up free tiers and open-source solutions. However, we have serious doubts about whether these tools are sustainable for a 30-unit setup. Is it actually feasible to manage annual fee calculations, operating cost statements (Nebenkostenabrechnung), and tenant accounting through a free tool without direct bank integration?
Are any peers running free software at a similar scale? Once the portfolio grows to 50 or 100 units down the road, how much of a financial and operational headache does it become to migrate data or upgrade to a paid tier?
