Runs right on top of the listings you already use:
No new workflow. No exporting to a spreadsheet.
Auction Day Rewards The Prepared And Punishes Everyone Else
The lot looks interesting. The guide price is tempting. So you register, turn up, and bid on instinct - trusting that the numbers feel about right. And only later, when you're deep in a refurb that's 40% over budget, do you discover you bid above your maximum and the deal was never going to work.
That's how auction buyers overpay. Not because they're reckless, but because auction day moves fast - and there's no time to build a spreadsheet when the bidding is already at £165k and rising.
Your spreadsheet can analyse the lot. It just can't do it in the 30 seconds before the bidding passes your limit.

Most Buyers Bid On The Guide Price. UPA Shows You What Happens When The End Value Drops.
Any tool can tell you a lot makes £34,993 at the expected sale price. The question that actually protects your money on auction day is: what happens when it doesn't sell for that?
With one click, UPA runs your lot through automatic sanity checks and downside scenarios, so you see the profit at 100%, 90% and 85% of your end value before you register to bid.
Same lot. Which number are you bidding to?
That's the difference between a winning bid and a winning deal.

Every Cost. Every Comparable. Every Exit. Before You Bid.
Your maximum bid is only as trustworthy as what feeds it. So UPA models the whole deal - purchase costs, refurb, finance, comparables and exit - then tells you your ceiling.
Every cost, not just the happy ones
Deposit, refurb, stamp duty, legals, bridging interest, auction fees, selling fees - totalled into the real cash you need in.
Comparable evidence, gathered for you
Nearby sold prices and £/sqm, scored for relevance, so your end value - and therefore your maximum bid - rests on evidence.
Exit strategy, modelled both ways
Compare a flip exit against a refinance-and-hold. Your maximum bid changes depending on your strategy. See which one works.
What UPA Does On Every Auction Lot
Your maximum bid. The most you can bid and still hit your target return. Calculated, not guessed.
Auction fees included. Buyer's premium, legal pack, auction house fees - all in the cost base.
Full cost modelling. SDLT, legals, finance, bridging, refurb, selling fees.
Comparable sales & rents. Evidence for your end value and yield, not a guess.
Downside stress tests. Profit at 100%, 90% and 85% of end value.
Saved deals & exports. Keep a record of every lot you model.
It's not a replacement for professional due diligence or a legal pack review. It's the fastest way to decide whether to bid and how high.
Auction Buyers Are Screening Lots In Seconds, Not Evenings
UPA is live with a founding cohort of UK property investors who are screening auction lots in seconds, not evenings.
Real testimonials from founding members coming soon. If you're an early user who caught a bad lot with UPA, we'd love to hear your story.
We Built This Because We Bid On Instinct Too
We're UK developers and investors. We were bidding at auction on guide prices and gut feel - and we still nearly overpaid on lots where the refurb was £20k light and the end value was a fantasy.
So we built the tool we wished existed: open a listing, click once, and see the maximum bid, the costs and the downside in one place.
Now we don't bid on anything without stress-testing it first. Neither should you.
