Worked property analyses
How we lay out the numbers behind a property decision. Each example uses a fictional property and rounded 2026 figures, so you can follow the method.
GetPost Labs is a technology company. We work with property data: the data you supply (loans, rent, costs, documents) and the data we research (sales, rents, rates and rules), and we apply our experience in building data and software systems to lay it out clearly. The outcome is structured information to help you answer your own questions with data. It is not financial, tax, legal, credit or valuation advice, and it is not a recommendation to buy, hold or sell.
The property, address and owners in this example are fictional, and the figures are rounded 2026 assumptions. Real outcomes depend on your circumstances and the market, so check decisions with a licensed financial adviser, accountant or registered valuer.
Selling one home to buy another
A family of four sells their three-bedroom home to buy a bigger one nearby: every cost on both sides, the new loan and three ways to do it.
Key findingChanging homes costs about $80,265, most of it stamp duty and the agent. Keeping the old home as a rental more than doubles the debt.
Hold or sell an investment property?
A couple tops up an investment house every month. Sell now and pay down their home loan, or hold for ten years and sell then?
Key findingIt turns on growth. Below about 3.3% a year selling wins; at 5% holding is about $178,057 ahead after ten years.
Buying a unit block: does it pay its way?
An investor weighs up a six-unit student block near a university. How much to borrow, and does the rent cover the loan?
Key findingThe block earns less than the loan costs. At the usual 70% loan it clears only $10,500 in year one.
House and land: the full cost of a new build
An investor buys a 420 m² lot and builds a four-bedroom home: land, build, stamp duty, stage payments and interest.
Key findingFrom contract to keys takes about 14 months; every payment, loan draw and interest charge is laid out in date order.
