Why use DealStack?

Many property calculators stop at gross yield. DealStack is designed for deeper underwriting: purchase costs, finance, operating expenses, stress scenarios, professional constraints, saved deals and exportable reports. You can start with manual inputs and move into paid reporting or live property-data lookup only when you need it.

Enter or retrieve the purchase, income, cost and finance assumptions.
Review the calculated outcomes and open any result card to see the underlying calculation.
Stress-test the deal and compare it with your investment criteria.
Save the analysis or export a professional report when required.
