Cashflow or Capital Growth: Which Actually Matters More
Two properties at the same price in different areas. One pays you twice as much every month. The other ends up £128,807 ahead. Here is the arithmetic.
Capital growth usually wins over a 20 year hold. Cashflow wins if you need the income now. On a £115,000 property, the lower yielding one in a better area produced £128,807 more total return over 20 years than the higher yielding one, despite paying £150 a month less the whole way through.
That’s the honest answer, and it’s uncomfortable for both camps. The yield chasers don’t like it because it says their monthly number is the smaller half of the picture. The growth people don’t like the follow up question, which is what happens if you need money before year 20.
Bullseye Properties Ltd is a buyer-only sourcing business working across South Yorkshire and North Nottinghamshire. I run this comparison for almost every client before we agree a brief, because it decides what I go looking for.
Which one should you optimise for?
Optimise for the one that matches what the money is supposed to do. If you need the rent to replace or supplement income in the next five years, cashflow is the constraint and growth is a bonus. If you’re building an asset base you won’t touch for a decade or more, growth is doing most of the work and cashflow just has to not lose money.
Most people never actually answer this. They look at a deal pack, see 9.4% gross, and buy. Nobody asked them what the money was for.
The two things pull against each other in practice. The streets with the highest yields are usually the ones with the weakest price growth, because the reason the entry price is low is the reason the demand to buy there stays low. You’re not choosing between a good deal and a bad deal. You’re choosing which half of the return you want more of.
The two options, side by side
Same purchase price. Same strategy. Different postcode.
| Option 1: high yield area | Option 2: better area | |
|---|---|---|
| Purchase price | £115,000 | £115,000 |
| Net cashflow | £300 per month | £150 per month |
| Net cashflow per year | £3,600 | £1,800 |
| Assumed annual capital growth | 1% | 5% |
Cash in is roughly the same either way. On a £115,000 purchase with a 25% deposit that’s £28,750 down, £5,750 of stamp duty at the higher rates for an additional property, plus legals, survey, mortgage arrangement and a sourcing fee. Call it £45,000 all in.
So Option 1 is returning £3,600 on £45,000, which is 8% on cash. Option 2 is returning £1,800 on the same £45,000, which is 4%. On the monthly numbers alone it isn’t close. Option 1 pays you double.
I’ve deliberately made Option 2 look weak. In the areas I actually buy in, net ROI (Return on Investment) after management, maintenance, voids and mortgage interest usually lands at 7 to 8%, not 4%. I’ve used the pessimistic version so the point holds even when the growth property is a disappointing earner.
What 20 years does to the gap
Total return here means cumulative net cashflow plus the increase in the property’s value. Growth is compounded annually on the £115,000.
| Option 1 (8% + 1%) | Option 2 (4% + 5%) | Option 2 advantage | |
|---|---|---|---|
| Year 5 | £23,866 | £40,772 | +£16,906 |
| Year 10 | £48,032 | £90,323 | +£42,291 |
| Year 15 | £72,511 | £151,077 | +£78,565 |
| Year 20 | £97,322 | £226,129 | +£128,807 |
Break it into the two halves and it’s clearer where the gap comes from.
Over 20 years Option 1 paid out £72,000 in cashflow and the property grew by £25,322, ending at £140,322. Option 2 paid out £36,000 in cashflow and the property grew by £190,129, ending at £305,129.
So the cashflow difference is £36,000 in Option 1’s favour. The capital growth difference is £164,807 in Option 2’s favour. The monthly number that felt like the whole deal turns out to be worth about a fifth of what the compounding did quietly in the background.
Why the highest yielding streets grow the slowest
Because yield is a price signal. A house lets for £650 a month in two different streets, but one sells for £70,000 and one sells for £115,000. The £70,000 one shows an 11.1% gross yield and the £115,000 one shows 6.8%. The market isn’t being stupid. It’s pricing in everything that makes the first street a worse place to own an asset for 20 years.
Crime is the usual driver, and it’s street level, not postcode level. In Doncaster in particular, two streets 400 metres apart can behave completely differently on void rates, arrears and price growth. Area level statistics will hide that from you entirely.
The honest version, and I’d rather say it plainly: I wouldn’t let my dog live on some of the streets that produce the best headline yields. Those streets probably won’t go up in value either. Those two facts are the same fact.
The catch nobody mentions: paper gains are not spendable
Option 2’s £190,129 of growth is real, but it isn’t money until you do something to release it. That means selling, which costs you agent fees, legals, and Capital Gains Tax on the gain if the property is held personally, or refinancing, which means qualifying for a new mortgage at whatever rates exist on that day.
Option 1’s £72,000 of cashflow arrived in monthly instalments you could actually spend. £300 a month covers a mortgage payment on something else. £190,129 locked in a house in year 18 does not pay a bill in year 7.
This is the genuine argument for cashflow and I don’t think growth people take it seriously enough. If the plan requires you to hold for 20 years, and something in year 6 forces a sale, you crystallise a much smaller gain and eat the selling costs. The strategy only works if you can actually complete it.
Can you get both?
To a degree, yes, and that’s what I’m actually looking for. The target is the middle of the curve rather than either end: properties between £80,000 and £140,000 in areas with real employment anchors, where the net return is 7 to 8% and the growth fundamentals are still intact.
Buying below market value is the other lever, and it’s the one most people ignore. Every property Bullseye Properties has sourced came in 10 to 20% below market value, the best of them 28% below the original asking price at 23 Beech Grove. A £115,000 property bought for £100,000 has given you £15,000 of the growth on day one, without waiting for the market to provide it. That’s four years of 5% growth taken up front, and it improves the yield at the same time because your cost base is lower against the same rent.
Value add does the same job. Turning a 2 bed into a 3 bed lifts the rent and the resale value together.
Does leverage change the answer?
It amplifies the growth side, which pushes the answer further towards Option 2 for anyone borrowing.
With £45,000 of cash controlling a £115,000 asset, you’re capturing the growth on the full £115,000, not on your £45,000. Option 2’s £190,129 of growth against £45,000 of cash invested is more than four times the money back, before a penny of rent. Option 1’s £25,322 of growth on the same £45,000 is about 56%.
The flip side is that leverage also amplifies the downside, and mortgage interest is the biggest single line in the cost model. Stress test at the current rate plus 1.5 to 2%. If Option 2 stops paying its own way at that rate, the £150 a month wasn’t a margin, it was a rounding error.
Which profile fits which investor
| If this is you | Lean towards |
|---|---|
| You need income inside 5 years | Cashflow |
| You’re 15 or more years from drawing on it | Growth |
| You’re buying one property, not five | Growth, because the compounding is your only lever |
| You’re building to a portfolio and need each one to service the next deposit | Cashflow |
| You couldn’t absorb a 3 month void and a £4,000 repair in the same year | Cashflow, and a bigger buffer |
| You’re paying higher rate income tax on the rent | Growth, since the gain isn’t taxed until disposal |
That last row matters more than people expect. Rental profit is taxed as income every year. Capital growth isn’t taxed until you sell it. Two identical total returns can leave you with very different amounts. I’m not a tax adviser and you should take proper advice on your own position, but it belongs in the decision.
What I would do next
Write down, in one sentence, what this money is supposed to do and by when. Then look at whatever deal is in front of you and ask whether it does that, rather than whether the yield looks good.
Then go and check the growth assumption yourself. Land Registry price paid data is free and it’s street level. Look at what houses on that specific street sold for in 2015 and what they sell for now. If the answer is 4% a year you have a growth asset. If the answer is 1% you have an income asset, and it should be priced and judged as one.
If you want the workings on a specific property, send it over. I’ll build the full cost model and the growth history on the street, and tell you which of these two things you’re actually buying. How it works covers the process, what it costs covers the fee, and the case studies show the numbers on four properties I’ve bought. If you’re weighing the mindset side of this rather than the arithmetic, cashflow priority vs wealth preservation goes at it from the other direction.
