Record House Prices in 2025: Was It Too Late to Invest?
March 10, 2025
When house prices reach a record high, people naturally wonder whether they have missed the opportunity. If the market has already risen, is buying now simply paying too much?
In my video published on 10 March 2025, I took a different view. I was interested in what higher prices, changing mortgage costs and leverage meant for a long-term investor, rather than treating a record as an automatic reason to stop buying.
This is a historical article based on that video. The market figures and forecasts describe the discussion at the time, not today’s rates or a current recommendation. In that recording, I described approximately £3 million of property, £2 million of borrowing and £1 million of equity.
You can watch the original record-house-prices video on YouTube. The most useful part of the argument is understanding the relationship between asset value, debt and cash flow.
What the January figures meant in the video
I used the Halifax House Price Index and discussed January’s monthly rise of around 0.7%, with annual growth around 3%. I preferred following one series consistently rather than switching between indices whenever another one produced a more exciting headline.
That consistency matters because different indices measure different parts of the market. An average based on mortgage transactions need not match an average drawn from all completed sales. The time period and data revisions matter too.
A record average also doesn’t mean every property has reached a record. Areas, property types and individual buildings can move differently. The national number gives context, but it isn’t a valuation of the house you are thinking about buying.
The question I wanted to explore was what a modest percentage rise could mean for someone using borrowing to own a larger asset base.
Leverage changes the return on your own money
Using the rounded portfolio figures in the video, 3% growth on £3 million of property is £90,000. Against £1 million of equity, that is 9% before costs and tax, assuming the debt balance is unchanged.
The property itself has not grown by 9%. The percentage on the equity is larger because the investor owns an asset partly financed by borrowing. That is the effect of leverage.
It is also why property can be powerful over a long period when bought and financed sensibly. The change in value applies to the entire property, rather than only the deposit originally supplied.
But the arithmetic works in both directions. A 3% fall on the same £3 million asset base would reduce value by £90,000 and, with unchanged debt, reduce the £1 million equity by 9% before other effects.
That is why I wouldn’t describe leverage as a guaranteed advantage. It amplifies exposure. The benefit depends on what the asset does and whether you can afford the borrowing while you own it.
A valuation increase isn’t money in the bank
A higher estimated value can improve the balance sheet, but it doesn’t automatically create cash you can spend. Realising value through a sale involves costs and potentially tax. Releasing equity through refinancing means taking additional borrowing, subject to lender approval.
The £90,000 example also isn’t a complete portfolio return. It excludes rental profit or loss, finance costs, maintenance, transaction costs and tax. Those need to be included if you want to measure the full outcome.
Inflation adds another layer. If the broader cost of living rises by a similar percentage to the property, the asset may have gained little in purchasing-power terms. Leverage can still change the return on the owner’s equity, but that doesn’t make inflation irrelevant to expenses or borrowing.
The point is to keep the different measures separate: property growth, equity growth, cash flow and the final after-cost return. They are related, but they aren’t interchangeable.
Mortgage costs made the difference very real for me
I described roughly £2 million of mortgages in the video. On that balance, a one percentage-point change in the interest rate represents £20,000 a year on an interest-only comparison.
That is why an apparently small rate movement gets my attention. It can materially change the money available after debt servicing, even when the property’s value is rising.
I discussed borrowing costs having moved substantially above the low-rate environment of 2021. Rents had also increased, but that didn’t necessarily restore the same profit margin. Higher rental income can be absorbed by more expensive finance and other costs.
A property investor should therefore care about both the asset value and the income statement. A portfolio can become more valuable on paper while producing less usable cash each month.
For a fuller explanation of that relationship, read my article on buy-to-let mortgage rates and cash flow.
Why I thought lower rates could support demand
My view in March 2025 was that easing rates could improve affordability for buyers and release cash for investors. That could support demand, although the timing and scale were uncertain.
For an investor, lower interest costs may leave more money for reserves or another purchase. For a homeowner, a lower mortgage payment can make moving more manageable or bring a previously unaffordable property within reach.
The effect isn’t immediate for everyone. Existing fixed-rate loans keep their agreed terms until a relevant change or renewal, and product fees can affect whether refinancing makes sense. Lenders also assess income and the property, not just the headline rate.
I was making an argument about a possible source of demand. I wasn’t saying a Bank Rate cut automatically produces an identical fall in every mortgage rate or a predictable increase in every property’s price.
Interest-only and repayment payments behave differently
The video used a £300,000 loan at 5% to illustrate the interest cost. On an interest-only basis, that is £15,000 a year, or £1,250 a month.
At 2.5%, the interest-only amount would be £625 a month. Halving the rate halves the interest component when the balance is unchanged.
A repayment mortgage is different because the payment includes capital reduction. Halving the interest rate doesn’t halve the whole monthly payment. The remaining term and balance determine the result.
That distinction is particularly important when comparing investors with people buying homes to live in. They may have different mortgage structures and different aims. A simple interest-only illustration shouldn’t be presented as a quotation for a household’s repayment mortgage.
I’ve explored the choice in more detail in my interest-only versus repayment article.
The forecast was conditional, not a promise
At the time, I thought rates somewhere around 2–3% over the following period were plausible, and I was optimistic about five-year property growth. I discussed a broad 25–35% growth scenario rather than claiming to know the exact outcome.
I also acknowledged that nobody knew what would happen to inflation, geopolitics, energy prices or the wider economy. Those unknowns could change the rate path and the property market.
A useful correction to any over-simple reading is that lower Bank Rate does not necessarily halve my actual mortgage bill. The products available, lender margins, fixed periods and fees all affect what I pay.
Similarly, a 33% rise on £3 million would be approximately £990,000 of additional asset value, but only if that growth occurred. It would not be £990,000 of guaranteed after-tax cash profit.
Historical forecasts are useful to review because they show the reasoning and assumptions. They should not be copied into a new buying decision without checking what has changed.
How lodgers helped me make my first purchase
I didn’t begin with a large portfolio. In the video, I described buying my first house for £176,000 in 2010 and renting two spare bedrooms for roughly £1,000 a month in total.
The mortgage payment was around £850 a month. Having lodgers helped meet that cost while I lived in the property, changing the economics compared with remaining in my previous rented accommodation.
Over the next five years, I described the house’s value increasing towards £300,000. I was fortunate with the timing and the outcome, and I said so in the video. Plenty of people had told me at the time that buying was a bad idea.
That experience taught me the value of getting started with a workable arrangement rather than waiting for universal agreement that the market was safe. It did not prove that every first purchase would rise that much or that every home is suitable for lodgers.
Check the practical rules before copying the lodger idea
Taking in lodgers can reduce the cost of owning a home, but the arrangement needs to fit the property and your circumstances. Mortgage, insurance, lease and local requirements should be checked before relying on the income.
The government’s Rent a Room Scheme guidance explains the usual £7,500 annual threshold for qualifying furnished accommodation in your home, halved where income is shared. Receipts above the threshold require the appropriate reporting and tax treatment.
Two rooms producing £1,000 a month in total means £12,000 of annual gross receipts if occupied throughout the year. That is above the usual threshold, so it should not be treated as entirely tax-free income.
Bills, maintenance and empty periods also matter. The financial benefit comes from the full arrangement after costs, not simply subtracting one mortgage figure from gross room rent.
My personal example is a useful starting idea, but somebody considering it now needs a current, property-specific budget and permissions.
A record price doesn’t settle whether a deal is good
A property can be a poor purchase below a previous market peak or a sensible purchase when an index reaches a new high. The price relative to local evidence, achievable rent and financing matters more than the headline alone.
I would ask whether the home is suitable for the intended use, whether the borrowing remains affordable under stress and whether enough cash is left for problems. If the investment only works with a strong forecast, I would want more margin.
I would also consider the time horizon. Property involves costs and can take time to sell. A person who may need the money back quickly faces a different decision from someone planning to hold for many years.
The lesson I took from my own early purchase was not to rush blindly. It was to do the work, understand the numbers and recognise that uncertainty will still exist when it is time to decide.
Build the case around the property you can buy
My March 2025 view was optimistic about the long-term combination of ownership, leverage and potentially easier borrowing. But the useful principle is to connect that broad view to a purchase that can stand on its own.

A record headline is a reason to examine the market. It is not a substitute for deciding whether the particular property, price and mortgage are right for you.
