As answered by people managing Innago and ZIP Code API.
Innago's answer
We’ve built our software from the ground up with small and large, independent landlords in mind. Since the very beginning, we’ve been meeting with property owners for direct feedback on which features matter and which don’t. We’re proud to say that we have a product our landlords and their tenants love. Innago is also free to use for landlords and property owners, yes you read that right! Our entire suite of features, from online rent collection to tenant screening, comes at no cost to landlords. We also know independent landlords and property managers pride themselves on their hands-on approach, and we do too. That’s why every one of our clients gets a personal account representative for themselves and their tenants.
Innago's answer
Too many property management applications are overwhelming, bloated with unnecessary features that drive up the cost and turn their software “solution” into a software problem. From day one, we've met and collaborated with landlords of all sizes to produce software that is free, effective, and efficient.
