Will This Property Actually Work As An HMO?

UPA reads any property listing and models it as an HMO - room-by-room rental income, total cashflow, ROI and comparable rents. Know if the numbers work before you buy, not after you've spent on planning and fire doors.

No new workflow. No exporting to a spreadsheet.

An HMO Is Only As Good As Its Room Income

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.

The Part Other HMO Calculators Skip

Most Calculators Show You Cashflow At Full Rooms. UPA Shows You What Happens When Rents Drop.

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.

At 100% of room rents, monthly cashflow£1,200
At 90%, cashflow drops to£640

Same property. Which number are you underwriting to?

That's the difference between an HMO that cashflows and one that drains you.

Every Room. Every Rent. Every Conversion Cost.

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.

HMO Investors Are Screening Deals In Seconds, Not Evenings

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 Built This Because We Were Guessing On Room Rents Too

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.
