Why You Can't Find HMOs to Buy (And Where They're Actually Hiding)

HMO Applications Hit a Record High. Available Stock Didn't.

According to FOI data published by Property Investor Today in April 2026, annual HMO licence applications in the UK climbed from 41,162 in 2018 to a record 57,725 in 2025 — a 40% rise in seven years. Some local authority areas have seen applications surge by nearly 1,000% over the same period. Edinburgh alone averages 5,158 applications per year, making it the de facto HMO capital of the UK.

And yet, if you open Rightmove or Zoopla today and search for HMOs to buy, you'll find a thin, inconsistent spread of listings — many mislabelled, most without the licensing detail you actually need to make a decision.

That gap is the problem. Demand for HMO investment is at an all-time high. Supply of properly listed, easily discoverable HMO stock is not keeping pace. The market has grown; the infrastructure for finding deals in it hasn't.

This isn't a niche frustration. It's the defining friction point for anyone trying to build or expand an HMO portfolio right now.

Why Generic Property Portals Are the Wrong Tool for HMO Sourcing

Rightmove and Zoopla are built for the residential market. They're brilliant at what they do — matching buyers to three-bed semis in commuter towns. But HMO sourcing is a fundamentally different problem, and using a general portal for it is like using Google Maps to find planning applications. The data is adjacent, not fit for purpose.

Here's what a serious HMO investor actually needs to know before making an offer: Is the property currently licensed? How many rooms does the licence cover? Has the council flagged enforcement action? What's the licence renewal date? Is the layout compliant with the local authority's HMO standards?

None of that lives on Rightmove. None of it.

Council inspection activity has risen 83% since 2018, and enforcement actions are up 180% over the same period, according to the same Property Investor Today FOI analysis. Buying an HMO without understanding its compliance history isn't just risky — it's how investors end up inheriting someone else's enforcement notice.

The fragmentation problem runs deeper than portals, too. A significant proportion of HMO transactions happen off-market — through specialist agents who maintain buyer lists, through landlord networks, through probate and portfolio disposals that never get publicly listed. If you're only watching Rightmove, you're watching the slowest, most picked-over slice of the market.

PropertyTok commentary — particularly the 'buy low up North' content that dominates the format — consistently points to off-market sourcing as where the real deals happen. That's not contrarian posturing. It's accurate. The best-priced HMOs in cities like Leeds, Sheffield, and Nottingham rarely surface publicly. They move before they need to.

The Off-Market Reality: Where HMOs Actually Trade

Off-market doesn't mean secret. It means the deal moved through a channel that wasn't a public listing portal.

Probate sales are one of the most consistent sources of HMO stock. When a landlord with a portfolio dies, the estate often wants a clean, fast disposal — not a three-month marketing campaign. Executors frequently sell to known buyers or through specialist agents at below-market prices to avoid the friction of a full open-market process.

Portfolio disposals are another. An experienced landlord retiring from active management will often sell multiple properties together, sometimes to a single buyer, sometimes through a broker who already has a shortlist of interested investors. These deals don't need Rightmove.

Then there's direct-to-vendor sourcing — investors who identify properties that could be converted or that are already operating as HMOs and approach the owner before the property reaches the market. This requires data: knowing which properties hold HMO licences, which licences are approaching expiry, which landlords have received enforcement notices and might be motivated to sell.

That's the data problem in a sentence. To source HMOs properly, you need licence data, compliance data, and ownership data — all cross-referenced and current. Assembling that manually, council by council, portal by portal, is the reason most investors give up and settle for whatever appears on Zoopla.

It shouldn't require that much friction.

What a Purpose-Built HMO Database Actually Changes

I've spent time looking at how investors actually find HMO deals, and the honest answer is: most of them rely on relationships and luck, dressed up as strategy. The investor who 'always finds good deals' usually has one reliable specialist agent, a solicitor who tips them off on probate sales, and years of accumulated local knowledge. That's not a system. It's a network that took a decade to build.

A purpose-built HMO database compresses that timeline by aggregating the data that currently sits in 400+ UK local authority portals, specialist agent feeds, and licensing records — and making it searchable in one place.

ZARSK is built specifically for this. It's what I'd describe as the largest constantly-updated HMO database in the UK, and the key word is 'constantly updated' — because an HMO database that's six months stale is worse than useless. Licence statuses change. Enforcement actions are issued. Properties change hands. The data has to be live to be actionable.

The practical difference for an investor: instead of spending hours cross-referencing council websites, you can search by location, licence status, room count, and compliance history — and surface opportunities that investors relying on Rightmove will never see. That's not a marginal advantage. In a market where the best deals move off-market and fast, being first to identify a motivated seller is everything.

For new investors, this matters even more. Without an established network, the database is the network. It's the entry point into a market that otherwise feels opaque and relationship-gated.

Financing the Deal: The Other Wall Most Investors Hit

Finding the property is only half the problem. Getting the mortgage — or freeing up equity in an existing portfolio to fund the next acquisition — is where a lot of investors stall.

HMO mortgages are a specialist product. Most high-street lenders won't touch them, and those that do often apply stress tests and rental income calculations that don't reflect how HMOs actually perform. A property generating £3,200 per month in rental income from six rooms can fail a lender's affordability model because the lender is applying single-let assumptions.

For experienced investors with existing portfolios, the problem is often different: the equity is sitting in assets that are difficult to refinance efficiently. Freeing up capital from a buy-to-let or HMO portfolio to fund new acquisitions requires a broker who understands both the product and the lender landscape — and that landscape changes faster than most investors track.

ZARSK's regulated finance partners specialise in exactly this. HMO mortgages for new investors, portfolio refinancing for experienced landlords looking to recycle equity — it's a team that's been operating in this space for over a decade, which matters when the mainstream market keeps moving the goalposts.

If you're at the stage where finance is the bottleneck, it's worth exploring what's possible at [zarsk.co.uk/finance-property](https://www.zarsk.co.uk/finance-property). Consider consulting a qualified financial adviser before committing to any mortgage product — but at least start the conversation with people who actually know the HMO market.

The HMO market isn't actually hard to enter. It's hard to see into. The 40% rise in licence applications since 2018 tells you the demand for this asset class is structural, not cyclical — people will keep needing affordable shared housing, and investors who hold well-run HMOs will keep benefiting from yields that single-let portfolios can't match. The barrier isn't opportunity. It's data access and finance access. Both are solvable problems. The investors who figure that out first — who stop waiting for Rightmove to hand them a deal and start working with tools and partners built for this market — are the ones who'll be looking back in five years wondering why everyone else waited so long.
