Harrow vs Watford HMOs in 2026: Which Area Is Giving Landlords Better Returns?

Ask ten landlords whether they'd rather buy an HMO in Harrow or Watford and you'll probably get ten slightly different answers.

It's one of those discussions that never really goes away. Every time a landlord starts looking for their next purchase, the same question tends to come up again. Is it worth paying more to buy in Harrow, or does Watford offer better value?

There's no obvious answer.

The reason people keep comparing the two is because they share a lot of the same strengths. Both attract working professionals, both have good transport links and both have remained busy rental markets over the past few years. Yet when you actually start looking at properties and running the numbers, the differences become clearer.

What makes things even more interesting is that investors aren't always looking for the same thing.

Someone building long-term wealth may view a property completely differently from somebody whose main focus is monthly income. That's usually where opinions start to split.

HMOs Haven't Gone Out of Fashion

You'd think that with all the additional regulations, licensing requirements and rising costs, some landlords would be moving away from HMOs altogether.

That hasn't really happened.

If anything, plenty of investors still see them as one of the few ways of producing strong rental income without buying multiple properties.

The logic is fairly straightforward. One family renting a house means one rental payment every month. Split that same property into multiple rooms and suddenly the income looks very different.

Of course, anybody who owns an HMO will tell you that the extra income isn't free money.

More tenants generally means more management. More wear and tear. More phone calls. More things that need attention.

That's partly why professional HMO Management Harrow services have become more common. Some landlords genuinely enjoy managing properties themselves. Others would rather spend their time finding the next deal than chasing contractors or organising inspections.

Harrow Still Feels Like Harrow

One thing that's interesting about Harrow is how consistent it's been.

Markets go through cycles. Demand rises and falls. Interest rates change. Yet Harrow has remained surprisingly resilient throughout most of it.

Good rooms near stations still tend to generate interest.

Properties close to Harrow-on-the-Hill, North Harrow and West Harrow rarely struggle to attract professional tenants, particularly those commuting into London several days a week.

That doesn't mean every property performs well.

Some landlords assume that simply buying in Harrow guarantees success. It doesn't.

Location still matters. Presentation still matters. Pricing still matters.

But generally speaking, demand isn't usually the issue.

The bigger obstacle for many investors is the initial purchase price.

Harrow isn't cheap. Most people know that before they even start viewing properties.

The higher entry cost can make some deals look less attractive on paper, especially when compared with locations a little further outside London. That's often where the debate starts.

Some landlords look at the yield and immediately move on.

Others take the view that paying more today could work out well over the next ten or fifteen years.

Neither approach is necessarily wrong.

Why Watford Keeps Getting Mentioned

Watford seems to appear on almost every investor's shortlist these days.

Part of that is because it sits in an interesting position. Close enough to London to attract commuters but often affordable enough to make the numbers work.

For landlords trying to balance purchase price and rental income, that's a combination that's difficult to ignore.

Many Watford Estate Agents say the same thing: demand hasn't disappeared.

People still want to live there.

Some work in London. Some work locally. Others simply prefer the area and the transport links it offers.

What's perhaps overlooked is that Watford isn't purely a commuter town anymore. There are plenty of people renting there who have little reason to travel into London at all.

That broader tenant base can be valuable because it reduces reliance on a single type of renter.

And when you're running an HMO, keeping rooms occupied is often just as important as achieving the highest rent possible.

The Numbers Don't Tell the Whole Story

One mistake newer investors sometimes make is becoming obsessed with yield.

It's understandable.

Yield is easy to compare. It gives you a quick way of measuring potential performance.

The problem is that properties don't exist inside spreadsheets.

Two HMOs can have identical yields and produce completely different experiences for the landlord.

One might suffer constant tenant turnover. Another could remain fully occupied for years.

One might require ongoing maintenance. Another might run relatively smoothly.

That's why experienced investors usually spend as much time looking at the property itself as they do studying the calculations.

Because at the end of the day, a good property in the right location tends to solve a lot of problems before they even appear.
