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.

Frequently asked questions

What does capital remaining mean?

Capital remaining is the acquisition basis plus modelled pre-let costs less refinance proceeds. It shows how much cash remains tied up after the refinance.

Can I stress the refinance value?

Yes. You can apply a valuation haircut and see the effect on refinance proceeds and retained capital.

Does DealStack forecast property values?

It can model user-defined appreciation scenarios, but these are scenarios rather than forecasts or valuations.
