Cashflow matrix
When they pay in, when it pays back
Payments laid out year by year: how much the client puts in and when, and from what point the property starts returning it.
Particularly useful for under-construction properties on extended payment plans, where the picture doesn't come together in conversation.
Year by year
The whole distance, not just the first instalment.
Payment plan
The developer's schedule is taken into account.
The turning point
When the flow changes sign.
