No new workflow. No exporting to a spreadsheet.

A BRRR Is Only As Good As Its Refinance Assumption

The listing looks like a tidy BRRR. Purchase, light refurb, refinance, pull your money back out. The spreadsheet says you'll leave £15k in. So you drive an hour to view it, offer, and only later - when the surveyor's valuation comes in £20k light and the comparable rents don't stack - do you realise you've left £35k trapped in a deal you can't exit.

That's how BRRR investors get stuck. Not because they're careless, but because they're guessing at the refinance valuation, the achievable rent, and the true refurb cost - across five tabs, under pressure, before someone else offers.

Your spreadsheet calculates the cash left in. It doesn't challenge the refinance valuation behind it.

The Part Other BRRR Calculators Skip

Most Calculators Show You The Refinance At 100%. UPA Shows You What Happens When The Valuation Comes In Low.

Any tool can tell you a BRRR leaves £12,000 cash in at the expected refinance valuation. The question that actually protects your money is: what happens when the surveyor values it £20k lower?

With one click, UPA runs your BRRR through automatic sanity checks and downside scenarios, so you see the cash left in at 100%, 90% and 85% of your refinanced value before you commit a penny.

At 100% of refinance value, cash left in£12,400
At 90%, you leave in£31,800

Same property. Which number are you underwriting to?

That's the difference between recycling your capital and trapping it.

Every Cost. Every Comparable Rent. Every Refinance Exit.

The BRRR is only as trustworthy as what feeds it. So UPA models the whole deal - purchase, refurb, refinance and the cash you'll actually get back out.

BRRR Investors Are Screening Deals In Seconds, Not Evenings

UPA is live with a founding cohort of UK BRRR investors who are modelling refinance exits and cash left in - in seconds, not evenings.

Real testimonials from founding members coming soon. If you're an early user with a BRRR UPA caught, we'd love to hear your story.

We Built This Because We Were Trapping Cash Too

We're UK developers and investors. We were analysing hundreds of BRRR deals a month, jumping between Rightmove, sold-price data, rent comparables, refurb estimates and spreadsheets - and we still nearly trapped £30k in a deal we thought refinanced cleanly.

So we built the tool we wished existed: open a listing, click once, and see the purchase, the refinance, the cash left in and the downside in one place.

Now we don't offer on a BRRR without stress-testing the refinance first. Neither should you.
