ERPNext for Apartment Complexes?

Is anyone on here using ERPNext for apartment complexes or offering a modified version of the same as a service which can be self-hosted by the complex?

I’m moving into an apartment soon, and the amount of data that private gate handling apps like MyGate get is absurd. I don’t want all my personal data to go into their hands. Of course, I do recognize that convincing the uncles of the society is going to be the biggest problem and not the software. But if anyone has gotten a start somewhere and how you’ll went about it, it would be great to hear.
