I’ve been writing about my mini-real estate journey throughout this blog: the decision to sell what had been our family home after renting it out: the thought process of buying my new rental: and the associated costs and process of getting to rented. Come and join me on Insta for more of the same, plus money saving tips, recipes, and frugal inspiration!

This week I wanted to look at the 1% rule, and whether it’s really relevant to those of us in the UK (and presumably a lot of the rest of Europe). As the majority of FIRE media creators seem to be from the USA, there is a lot of talk about how fabulous real estate is as a wealth building tool, and lots of great advice about how to calculate options and, essentially, when things are a good idea.

But does the 1% rule work outside of the States?

The 1% rule is a way of thinking about whether the rental property will make is going to pay off the value of the home in a reasonable timeline. As a property investor, this is an indication of a plan which is likely to make you money in the long term rather than being something that just breaks even.

So – if you buy a house for $200,000, it should rent out for $2,000 – or a $300,000 house for $3,000 etc. The purchase price should include everything it takes for you to get the house tenanted. So any renovations, upgrades, essential additions such as smoke or carbon monoxide alarms; along with legal costs of purchase, and of setting up as a rental.

Once you have tenants in place, you will also need to pay a bunch of costs from the income, including maintenance and repairs, taxes, landlord insurance etc. You can think about this as the 50% rule whereby you assume you’ll spend 50% of your income as oprating costs over the long term. You might not – and you might spend very little for a few years then have to repair a roof – but preparing for that spend is part of being a landlord.

So I had a look at some average house and rental prices in the UK to see how it might work. I’ve gone with the median house price rather than the mean since every area of the UK has super expensive enclaves and properties which are not reflected further down the chain. This is true everywhere, but in Cheshire where my rental property is, average prices are around £260,078 also includes the Golden Triangle where homes are more like £2,600,000. So the median is a more useful figure for back-of-the-envelope thinking.

	Rent 23	Median house price		Rental return
North West	£                  958	£         185,000		0.52%
Greater London	£              1,804	£         533,687		0.34%
North East	£                  594	£         140,000		0.42%
South East	£              1,164	£         388,900		0.30%
UK minus London	£              1,113	£         272,000		0.41%
My previous rental	£              1,225	£         450,000		0.27%
Current rental	£                  895	£         235,000		0.38%

Looking at a few different areas (which are roughly the more expensive and less expensive parts of England and Wales) it looks like the average likely return in the UK is about 0.38% – significantly less than the 1% used in US calculations.

This makes sense to me in terms of the house prices here, and what renters could actually afford. The chances of the average person being able to pay rents otherwise are basically zero. In the South East for example, the average income is £40,300 and take home monthly pay £3,358. The 1% rule would expect that an average rent here would be £3,889 – or significantly more than the average take home pay.

So there are multiple factors at play, which make sense. But it’s also helpful to know what’s likely. It doesn’t make investing in property in the UK a bad idea (more of the pros and cons another time) but hopefully this information is useful in your own planning and calculations.
