How to Avoid Buying a Problem HMO
March 23, 2026

A cheap readymade HMO can look like a smart buy at first. The photos may seem tidy. The income figure may look strong. The brochure may make everything sound simple.
That is exactly where many investors get caught out.
In our 34 years of developing and managing HMO properties, we have seen countless investors inherit issues they did not expect. Right now, more problem HMOs are coming onto the market. Many sellers price them cheaply to attract attention, and on the surface they can look appealing. In reality, many of them come with risks, hidden costs, and long lists of overdue work.
Tired or rogue landlords often sit behind these sales. They have failed to keep up with compliance, maintenance, and changing regulations. Over time, the workload has grown, the costs have risen, and the property has become too much for them. Rather than fix the issues properly, they put the HMO up for sale and move the problem onto the next buyer.
Rental reform and EPC deadlines are adding even more pressure. As a result, many distressed HMOs that no longer stack up are now appearing on the market. That creates a real danger for investors who focus too heavily on the low price and not enough on the condition of the asset.
Why cheap can become expensive
A low purchase price often creates a false sense of value.
Many investors assume buying cheap means getting more for their money. In the HMO world, the opposite is often true. What looks like a bargain can quickly turn into a costly project once poor workmanship, outdated electrics, plumbing issues, damp, weak fire safety measures, tired boilers, poor layouts, and years of neglect start to come to light.
Most of the real cost stays hidden on day one.
Later, it shows up through repair bills, compliance upgrades, voids, refinancing issues, management headaches, and constant snagging. Once you add all of that together, the so called bargain often looks like a very poor investment.
The danger with tired landlord stock
Many of the problem HMOs coming onto the market today follow the same pattern.
A landlord has owned the property for years. During that time, standards have slipped. Repairs have been delayed. Compliance has gone onto the back burner. Maintenance has become reactive instead of proactive. Eventually, the property stops performing as it should.
At that point, the landlord wants out.
To a new investor, the listing can still look tempting because the price is low and the building already operates as an HMO. However, the discounted price usually exists for a reason. In many cases, the buyer takes on years of underinvestment and a long list of expensive issues.
Compliance is not something to guess
One of the biggest mistakes an investor can make is assuming a property is compliant just because tenants already live in it.
That assumption can become very expensive.
A tenanted HMO does not automatically meet the right standard. The fire safety measures may fall short. The layout may no longer work. The electrics or plumbing may need major upgrading. Insulation, heating, ventilation, and licensing standards may also need attention.
In other words, an existing HMO can still be a problem HMO.
Investors need to look beyond the fact that the property is already up and running. The real question is whether the landlord developed and maintained it to a standard that protects both income and long term value.
Readymade does not always mean reliable
Readymade properties attract investors because they appear easier. Buying something that already looks finished and already has tenants sounds convenient.
However, that convenience comes with a major risk.
You do not know what lies under the floorboards or behind the walls. That is one of the biggest dangers with buying a second hand HMO. Fresh paint does not tell you the age of the electrics. A smart kitchen photo does not tell you whether the plumbing has been replaced properly. A tidy bedroom does not tell you whether someone dealt with damp correctly or simply covered it up.
Many buyers rely too heavily on what they can see, yet the most expensive problems usually hide where they cannot.
What investors should look for before buying
To avoid buying a problem HMO, investors need to dig deeper than the asking price and brochure.
Focus on the quality of the refurbishment, not just the appearance. Ask what the developer or landlord actually replaced. Ask how far the work went. Find out whether they stripped the property back properly or simply patched it up to make it look presentable.
Pay close attention to the following areas:
The electrics
Are they modern, safe, and suitable for the size and use of the property?
In our HMO refurbishments, we install brand new electrics throughout. That gives investors confidence that the system is modern, safe, and built for the demands of a high performing shared house.
The plumbing and pipework
Has the system been upgraded properly, or is old infrastructure hiding behind new fittings?
As part of our refurbishments, we replace plumbing and pipework throughout. That removes the guesswork and helps protect investors from hidden future costs.
The boiler and heating system
Can it cope with the demands of a busy multi let property?
We modernise the heating system and install suitable boiler setups so the property can handle the demands of a fully occupied HMO.
Fire safety measures
Do the corridors, doors, alarms, and escape routes meet a proper standard?
We take fire safety seriously in every refurbishment. That is why we include fire protected corridors and the safety measures needed for a compliant and robust HMO setup.
Damp proofing and plastering
Did somebody solve the issue properly, or simply cover it up?
Our team strips projects back properly and installs new damp proofing and new plaster. That approach deals with the root issue instead of hiding it for the next owner to discover.
Bathrooms and ensuites
Are they newly installed and built for repeated daily use?
Our refurbishments include 5 or 6 brand new ensuites where required. That gives investors modern bathrooms built for regular tenant use and long term durability.
Kitchens and communal areas
Do they match the standards tenants expect in a competitive market?
We install modern kitchens and create practical communal spaces that appeal to professional tenants and support strong long term occupancy.
General build quality
Did somebody carry out the work for longevity, or just to get the property sold?
This is where our approach stands apart. We strip properties back to brick and modernise them properly with long term performance in mind, which helps reduce maintenance risks over time.
Why quality upfront matters for long term performance
A properly developed HMO should work for the long haul.
That means much more than making it look good for sale. Investors need a property that performs well, stays compliant, and avoids constant maintenance problems. Strong development work creates a durable, efficient, and easier to manage asset.
When investors develop a HMO with us, we strip the property completely back to brick. From there, we rebuild it properly with new plaster, new damp proofing, new electrics, new plumbing, new pipework, boiler upgrades, fire protected corridors, kitchens, 5 or 6 new ensuites, lighting, walls, and full modernisation throughout.
That level of work matters because it helps hedge investors against maintenance costs over the long term. It creates a stronger asset from the outset and reduces the risk of nasty surprises later.
This is not about a hard sales message. It is about helping investors understand why build quality matters so much in HMO investment.
Auctions and bargain stock need extra caution
Auction properties and heavily discounted HMOs often grab attention because they seem to offer below market value.
Sometimes they do. Often they do not.
In many cases, these properties come with serious unknowns. Buyers cannot always verify the quality of the work. They may not get enough time to inspect every detail. They may also miss the full story around compliance, repairs, ageing systems, and years of neglect.
Too many people overlook those risks because the property looks cheap. That is a major mistake.
Price should never drive the whole decision. Quality, compliance, durability, and long term viability matter far more.
Focus on what the property will be like in five years
A good HMO investment should not only work on the day you buy it.
It should still work in five years, ten years, and beyond.
That means asking better questions. What hidden work still needs doing? How strong is the asset really? Will this property save me money over time, or drain it? Is the current price masking future expense?
That shift in thinking helps investors avoid costly mistakes.
A better way to assess value
Real value in a HMO comes from reliability, quality, compliance, and long term performance.
Investors need confidence that the property has been modernised properly. They need to know the systems behind the walls are as strong as the finish in the photos. Above all, they need an asset built to last, not one dressed up to sell.
That is why investors need to stay careful when a property looks cheap on paper. Many of them are cheap for very good reasons.
