How to pay property taxes?

[Bellman Tumasang]

Investors who own commercial property such as apartment buildings how do you pay property taxes? I was reading an article on this link https://www.nolo.com/legal-enc... and it said you complete an income and expense form. Where do I get this form from?

Anyone who invests in property how do you do this? Do you have an accountant who handles this? Do you do it yourself if so how and when?
