About Investor Sums

Investor Sums makes free, plain-language tools for people who own investment property in Victoria. Land tax is hard to follow, the deadlines are short, and most owners never check their numbers. We built the tools we wished existed.

What you get, free

• The land tax check and the deadline calculator.
• Guides that answer one question each, with official sources.
• A short reminder before each date that matters.
• A new plain-words article every three days.

What to expect from us

• Plain words. If a child or a grandparent cannot follow it, we rewrite it.
• Official sources, linked on every page.
• Your numbers stay on your own device. We do not sell your details.
• Honest answers. Most valuations are fair, and we say so.

When you need a professional

We give general information. We are not an estate agent, a valuer, a tax agent or a law firm, and we do not act for you. If you ask us to point you to a professional, you will see who they are and any fee involved before your details go anywhere, and the choice is always yours.

Who we are

Investor Sums is operated by Goldina Group Pty Ltd, ABN 47 684 636 315, in Victoria, Australia. You can reach us at hello@investorsums.com.au.
