Runs right on top of the listings you already use:
No new workflow. No exporting to a spreadsheet.
The listing looks like a solid HMO conversion. Five double rooms, £450 each, the numbers stack on the back of a fag packet. So you buy, you convert, you licence - and only then do you find two rooms won't pass HMO standards, the achievable rent is £380 not £450, and the cashflow is negative.
That's how HMO investors lose money. Not because the strategy is wrong, but because they're guessing at achievable room rents, true conversion costs, and licensing requirements - across five tabs, under pressure, before someone else offers.
Your spreadsheet calculates the HMO income. It doesn't challenge the room rents behind it.

UPA reads the listing and models the HMO income, costs and cashflow.
Room income, total cashflow, ROI and the downside - all on the page.
The Part Other HMO Calculators Skip
Any tool can tell you an HMO cashflows £1,200 a month at the expected room rents. The question that actually protects your money is: what happens when two rooms sit void and the others rent for less?
With one click, UPA runs your HMO through automatic sanity checks and downside scenarios, so you see the cashflow and ROI at 100%, 90% and 85% of your room income before you commit a penny.
Same property. Which number are you underwriting to?
That's the difference between an HMO that cashflows and one that drains you.

↑ At 90% of room rents, monthly cashflow drops to £640. Half gone.
The HMO is only as trustworthy as what feeds it. So UPA models the whole deal - room income, conversion costs, comparable rents and cashflow - not just the headline number.

See the total rental income broken down by room - so your cashflow rests on individual room rents, not a round-number guess.

Nearby rental evidence and £/sqm, scored for relevance, so your room rents rest on evidence, not one optimistic estimate.

Purchase, conversion build costs, fire doors, licensing, stamp duty, finance - totalled into the real cash you need in.
Room-by-room income. Total rental income broken down by individual room.

Full conversion cost modelling. Purchase, build costs, fire doors, licensing, SDLT, finance.
Downside stress tests. Cashflow at 100%, 90% and 85% of room income.

UPA is live with a founding cohort of UK HMO investors who are screening deals in seconds, not evenings.
Real testimonials from founding members coming soon. If you're an early user with an HMO UPA caught, we'd love to hear your story.
We're UK developers and investors. We were modelling HMOs on round-number room rents - and we still nearly committed to a conversion where two rooms wouldn't licence and the cashflow was fiction.
So we built the tool we wished existed: open a listing, click once, and see the room income, the cashflow and the downside in one place.
Now we don't offer on an HMO without stress-testing the room rents first. Neither should you.

Your first 48 hours are free. When you're ready for unlimited, lock in the founding price.
