How to use AI for Property Auctions
The world has changed. AI has put cheap, accessible research into the hands of the private investor.
What is AI in this context?
Strip away the hype and you are looking at large language models, LLMs for short. Software trained on vast quantities of text that can read, summarise, compare and reason across documents at a speed no human can match. The two names you need to know are OpenAI, the company behind ChatGPT, and Anthropic, the company behind Claude.
Anthropic in particular has become the engine inside the legal sector. The leading legal AI platforms, Harvey and Legora among them, run on Claude. If a magic circle firm is triaging a thousand-page contract, the odds are Anthropic's model is doing the heavy lifting underneath.
Now bring that capability into a property auction.
Be clear about what AI is doing for you. It is filtering and sifting. Nothing more. It reads the legal pack at machine speed, surfaces the points that matter, flags the clauses you would otherwise miss, and saves you days of reading. That is its job. It is the first pass, not the final word.
It is not making the decision. You are. And the decision to bid is never made on the AI's word alone.
I made this point from the Property Auction Panel at the recent Property Investor Show, hosted by Property Investor Media. I will make it again here. Before you raise a paddle or click a bid online, you must instruct a solicitor to report on any document the AI has analysed.
That is non-negotiable.
No AI is one hundred per cent correct. None of them. Your solicitor carries professional indemnity insurance. If they get it wrong, you have recourse. If the AI gets it wrong, you have a lesson and a loss. That is the difference, and it is the whole reason the human professional sits at the end of the process.
So, the workflow is this. Use the AI to do in minutes what would otherwise take hours or even days. Sift many lots with the machine, sign off any you will bid on with a solicitor. Legal packs can now be sifted in bulk for less than the price of a small packet of crisps.
And the filtering does not stop there.
Train the model, which anyone who can use a keyboard can do, and the results are incredible:
· Legal pack analysis and reporting
· Pre-bid enquiries to send to the auction house
· Comparable sales data and commentary
· Risk profile
· Refurbishment costings
· Flip versus hold prospects
· Yield, ROI, ROCE, sensitivity analysis. modelling.
All of it, sorted and laid out, in minutes, for peanuts.
It works whatever your strategy. It works whatever your method of purchase, auction, private treaty, off-market, or anything else.
This changes the economics entirely. A few pence to do work that, just a few years ago, would have run to thousands of pounds in solicitor's time, or simply would not have been done at all.
Last weekend I cancelled my subscriptions to the real estate data providers I had paid for years. They were costing me thousands of pounds annually.
For twenty pounds a month, and with the right prompts, AI replaces all of it. For transparency, I use the ninety pounds per month model due to the volume of activity I have with AI, not just for property, but other things I do, but my mentees requirements are met with just two hundred and forty pounds per annum.
It is truly revolutionary.
It is also a leveller. The private individual now sits at the same table as the institutional buyer.
A word of caution on the tool itself. You get out what you put in. Ask a vague question, you get a vague answer. Feed it the wrong document, you get the wrong analysis. The skill is in the prompt, and in the judgement applied to what comes back.
The AI is universal. Anyone can use it. The cost is negligible.
But never forget what it is. A filter. A sieve. A first read at extraordinary speed. The solicitor's report is what you bid on.
Frequently Asked Questions
Can AI replace a solicitor for property auction legal packs?
No. AI is a filter and a first read. It surfaces clauses and flags issues at machine speed, but the bidding decision must always be supported by a solicitor’s report. Solicitors carry professional indemnity insurance. AI does not. If the AI gets it wrong, you have a lesson and a loss. If the solicitor gets it wrong, you have recourse. That is the difference, and it is the whole reason the human professional sits at the end of the process.
What can AI do for a property auction investor?
Trained correctly, AI can produce legal pack analysis and reporting, draft pre-bid enquiries to send to the auction house, pull comparable sales data and commentary, build a risk profile, estimate refurbishment costings, model flip versus hold prospects, and run yield, ROI, ROCE and sensitivity modelling. All sorted and laid out in minutes, for the cost of a low monthly subscription.
How much does AI cost to use for property auction analysis?
A standard ChatGPT or Claude subscription is around £20 per month, or roughly £240 per year. For most private investors that is sufficient. Heavy users move up to higher tiers, around £90 per month, where activity volume justifies it. Either way, it replaces real estate data subscriptions that previously ran to thousands of pounds annually.
Which AI models are best for property auction due diligence?
The two leading large language models are ChatGPT, made by OpenAI, and Claude, made by Anthropic. Claude is the engine inside the leading legal AI platforms used by major law firms, including Harvey and Legora. Both are suitable for legal pack analysis when used with disciplined prompts and a solicitor’s sign-off at the end.
Does AI work for buying property outside of auction?
Yes. The same workflow applies whether you buy at auction, by private treaty, off-market, or by any other route. AI sifts the documents and the data. The solicitor signs off the deal. The method of purchase does not change the principle, and neither does the strategy, whether you are flipping, holding, or running a BRRR.
