The Property Investment Platform Built for Australia
Presm is the property investment intelligence platform that Australian investors and property professionals use to model portfolios, track cash flow, forecast wealth over 30 years, manage deals from presentation through to settlement, and run every calculation that matters along the way. Our full suite of tools and calculators cover stamp duty, lenders mortgage insurance, borrowing power, land tax, rental yields, entity structuring, and more across every state and territory. First home buyers mapping out purchase costs, experienced investors optimising their cash flow and tax position across multiple properties, and professionals managing a pipeline of clients and deals all use Presm for the same reason: the tools, data, and visibility to move with total confidence.
The Client Portal
From strategy session to settlement. Every step, one portal.
Each client portal gives you a live view of your property investment as it unfolds. Portfolio value, equity, and loan positions update automatically. Holding costs break down to the week so you see exactly what each property costs to own. Cash flow and wealth projections run out to 30 years. When a deal is presented, you review it, approve it, and follow it from contract exchange to unconditional settlement inside the same portal. Strategy, financials, property data, and deal progress sit in one place with nothing to chase up separately.

Why these calculators matter
Property investment in Australia isn't just about picking a suburb and hoping for the best. The difference between a good deal and a great one usually comes down to the numbers you run before you buy. Stamp duty, holding costs, rental yield, tax structuring, and long-term growth projections all play a role.
Most investors either skip the analysis entirely or cobble together spreadsheets that miss half the picture. These calculators are purpose built for Australian property, so they handle state specific rates, investor surcharges, and the quirks of our tax system out of the box.
Buying your first investment property or adding to an existing portfolio, these are the numbers you need before you move. Having accurate figures gives you the confidence to act quickly when the right opportunity comes up. No more second guessing, no more back of the envelope maths.
