In this first episode, we're not talking calculators yet. We're talking about why this platform exists in the first place.

It started with a development deal that looked solid on paper. Twelve flats, good location, experienced developer. But hidden inside a spreadsheet they'd used for fifteen years were errors that turned a projected £320,000 profit into a £90,000 loss. They'd never spotted them. Nobody had.

That moment crystallised something we'd seen repeatedly in development finance: smart, experienced property professionals making expensive mistakes not because they couldn't do the maths, but because they forgot to include something, used the wrong formula, or made optimistic assumptions without realising it.

This episode explains the thinking behind PropertyCalculators.ai. Why we believe better analysis leads to better decisions. Why we built tools that force you to confront the questions you might otherwise skip. Why we've created over 70 specialist calculators covering development finance, buy-to-let, HMOs, leasehold, bridging, and more – all built specifically for how UK property investment actually works.

Whether you're a seasoned developer or analysing your first buy-to-let, this episode sets the foundation for everything that follows.

The best deal you ever do might be the one you walked away from because the numbers didn't work.
