Plan a fair offer price on a house from the facts you have

You like a place and don't want to overpay. Get an offer framework from comps you've gathered, not a guess.

Updated 17 Oct 2026

The prompt · ChatGPT

Help me plan a fair offer price on a house.

Asking price: [amount]
Sold comps I've found: [addresses or links, prices, dates]
How long listed / price cuts: [if known]
Survey or concerns: [any]
My max based on mortgage/savings: [amount]
Chain situation: [if known]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. An offer band with reasoning from my comps.
2. What would move me to the top or bottom of the band.
3. Negotiation lines for the agent.
4. What to check with my mortgage broker or solicitor next.
5. A reminder this is not a formal valuation.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, figures or products. This is help organising my own numbers and wording, not financial advice; point me to MoneyHelper, GOV.UK or Citizens Advice for guidance, and to a free regulated debt adviser if I'm struggling to pay. UK English.

Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.

A short example

Fill the blanks, then paste. amount: a short note you already have. addresses or links, prices, dates: a short note you already have. Leave the rest of the prompt as written.

This does not give tax advice. The books stay in the accounting system.
