This is part of a series of pieces of analysis and comment on the subject of UK property.

The first deals with the question of why most people believe property ownership to be such a sure-fire winner, and to examine both how it has actually performed as an asset and to understand why certain unique factors have aided the perception of outsized gains and stable prices.

My castle

Beyond the fulfilment of a wish to own a piece of this sceptred Isle; buying a house is also thought of by most as being the best financial investment they can make.

But is this actually true?


Using the Nationwide Building Society’s figures, house prices in the UK from 1975 until 2015 have increased in real terms by around 130%.

The first thing to note is that this excludes inflation; it’s the measure of the above inflation (or real) increase and therefore represents the actual profit being made (the inflation element is not profit, it simply keeps the value of money the same year after year).

Safe as houses

Most people view stocks and shares as volatile and unpredictable, whilst they perceive property as physical, useful and understandable.

Bricks and mortar is far more comprehensible to most than the P/E ratios and discounted cash flow calculations of share analysis.

People generally therefore believe a property investment is literally “as safe as houses” with surveys regularly confirming that the vast majority think it a superior and less volatile investment than equities.

But again is that actually true?

Just the facts please ma’am

Few people will initially believe the following figures but they are how it really is!

On average in the UK if you bought a house in 1975 the real (removing inflation) value was broadly the same in 1990.

No gain in 15 years.

Further, if you bought a house in 1988 you would have lost money until 2002, at the bottom in 1995 you would have been down around 40%.

More recently if you bought in 2008 and sold in 2013 you would have lost 28%.

To bring it up to date, the average house price in 2015 is only now equal to the prices paid in 2003; you would in real terms have made no money over the last 12 years.

So why the massive misconception?


Well the first thing that confuses people is the enormous effect inflation has played in the perception of increasing values.

House Prices UK

The UK until the late 1990’s had high inflation rates (really only Italy in Europe was comparable and guess what, they love owning property too).

Few people would remember now that the average mortgage rate in the 1990’s was around 12%, by today’s standards that’s unthinkable, but that’s what it was and it was so elevated because we had an average inflation rate of 7% plus for much of the decade.

The real return of 130% on house prices since 1975 will simply not ring true for most, especially those old enough to remember buying a first property for £15,000 and it now being worth in excess of £200,000. Well it will help to put that into context if you factor in that compound inflation is over 800% in that same period (since 1970 a takeaway Fish and Chips now costs over 7000% more and even since the year 2000 a loaf of bread has risen 150%).

As a comparison in low inflation countries such as Germany, there is no significant home ownership culture partly because there has been no high post-war inflation rate.


Far and away the most productive investment method for maximising gains on rising values is to use gearing.

So if something rises by 7% per annum over ten years and you invest £10,000 of your own money, you make a profit of £10,000.

100% return

But if you invest £100,000 by borrowing £90,000 and still putting in your £10,000.

Well now you’re talking.

You make £100,000 profit.

That’s TEN TIMES your initial investment.

1000% return.


The affordability (cost of servicing as a % of income) of a mortgage (gearing) is historically onerous in the early years of home ownership but over time it eases.

Mortgage Payments percentage of income

This again is primarily a factor of inflation but more recently also of falling interest rates.

In periods of high inflation, wages will rise each year by the inflation rate as a minimum to keep pace with rising costs (inflation is a key metric for public sector wage negotiations as an example).

So if a mortgage is taken out on a multiple of 3 times earnings, after ten years of 5% inflation those earnings will have risen by over 60%, if they rise say 3% above inflation then they will have roughly doubled.

In simple terms in the above scenario the family income rises over time and assuming interest rates stay the same, the mortgage cost doesn’t. So affordability as a percentage of earnings is down to a borrowing of 1.5 times earnings, which is much easier.

This either allows for a more expensive house to be purchased or for a higher level of disposable income to be enjoyed.

The best bit is the symmetric relationship and benefit to the borrower between inflation and interest rates which are the two main elements of a mortgage. If inflation rises then that helps as wages increase quicker, and if it falls then so usually would interest rates which equally helps affordability.


As this is only the first of the pieces there are a number of other factors not yet covered that will need to be part of any balanced conclusion.

It is however possible to conclude that:

  1. Few would believe that the real rate of return (ex-inflation) for UK property since 1975 is in fact 2.9% pa
  2. Few realise that they have in fact utilised gearing to levels which in any other type of investment would be deemed utterly reckless. We will be looking at share performance as a comparator and it will be interesting to see what gains or losses would be made from gearing a FTSE All Share investment in 1975 by the same amount as a 90% mortgage
  3. Inflation has risen far more in 40 years than people think
  4. House prices have in fact been far less predictable and far more volatile than most assume
