THE BUY — Big Purchases OS Brain
For the largest cheques you'll ever write. House, car, renovation, contractor. One orchestrator plus ten specialists that value the thing properly, model what it really costs, build the offer, and hold your ceiling when the room gets warm.
What makes it different
It argues the seller's side first. Their motive, their pressure, their alternative, and the things they know that you don't. Then it sets your ceiling before a single number is spoken aloud — because most bad purchases aren't bad deals badly negotiated, they're good negotiations on the wrong thing at a number somebody else chose.
Say it in plain words — it works out the rest
"They want £14,500 for a 2019 estate"→ comparables before any offer
"Builder quoted 40k for the extension"→ full pipeline, gates on
"What am I not seeing here?"→ 03 · seller's side
"There's another buyer, I need to decide today"→ 08 · priced as a tactic
"Survey found damp. Walk away?"→ 09 · ruled against your ceiling

Where it refuses to skip ahead
- No number before comparables — an offer built from the asking price is their number wearing your clothes.
- No offer before total cost — sticker price is not price. Fees, finance, running costs and exit all count.
- No commitment without inspection — skip a check if you like, but the risk gets a figure attached.
- No decision under manufactured pressure — the ceiling decides, not the deadline someone invented.
