Property owners underestimate their costs.
Most owners (families, friends, couples, and landlords) know their rent but forget maintenance, rates, insurance, mortgage interest and many other expenses.
The property investment platform that shows your real ROI.
Whether you own alone or with partners, FairSquare tracks every expense and dollar of income against your property — so you always know your true return.

Most property owners don't actually know their return on investment.
Without expense and income tracking, ROI is a guess.
You can estimate based on purchase price and rent, but your real return depends on every dollar in and out — including costs you share unevenly.
Unclear numbers create tension between co-owners.
Disagreements over who owes what put relationships under pressure. When every transaction and split is visible to all owners, there's nothing to dispute.
Spreadsheets don't scale for shared investments.
Tracking who paid what across mortgages, repairs, insurance, and rent across multiple owners breaks down fast. One missed entry and nothing adds up.
How FairSquare calculates your return.
💡Mortgage payments are automatically logged via mortgage tracking — no manual entry needed.

Common questions
What is FairSquare?
FairSquare is a web app for tracking property investment expenses, income, and ROI — for individual landlords, co-investors, couples, and Airbnb cohosts. It automatically calculates each owner's true return based on their ownership stake and actual transaction history.
Who is FairSquare for?
FairSquare is for anyone who owns investment property — whether alone or with others. This includes friends and family investing together, couples with a rental, individual landlords, business partners in a syndicate, and Airbnb cohosts splitting income and expenses.
How does FairSquare calculate ROI?
FairSquare calculates ROI from actual transaction history — total capital invested, running expenses, rental income received, and current equity value — giving a more accurate return figure than price-based estimates.
How is rental income handled?
Rental income is automatically applied against mortgage and operating expenses before calculating net amounts owed. Co-owners are only reimbursed for the net shortfall, not the gross cost.
Can I use FairSquare if I own a property by myself?
Yes. FairSquare works for sole owners as well as co-owners. Individual landlords use it to track all their costs and income in one place and see their true yield after every expense.
How is FairSquare different from a spreadsheet?
You could build it in a spreadsheet (good luck!) — but you'd have to write every formula yourself: ownership splits, income offsets, ROI per person. How well it works depends entirely on your spreadsheet skills, and one wrong cell breaks everything. FairSquare does all of this out of the box, with no formulas to write or maintain. Every owner also gets their own personalised dashboard, which a shared spreadsheet simply can't do.
