A property deal is more than sale price minus purchase price

BRIX Calc answers these four questions in seconds: every assumption calculated, every risk visible before you exchange.

Do you have every cost line in view? From Stamp Duty and planning fees to building regs, utility connections and surveys. Together they eat into your margin.

What does a 0.5% rate rise do to your DSCR, ICR and payback period?

Do you know what one month of delay costs you?

Gross, every deal looks good. What do you actually keep, net?

From property to decision in three steps

Buying beyond the UK?

Done fiddling about in Excel?

As a property investor I spent far too much time building, adjusting and checking Excel sheets.

So I built BRIX Calc, with one mission: to make messy, clumsy and error-prone property models a thing of the past.
