Areas containing more than a third of UK homes are now recording annual price falls, according to Zoopla figures published on 27 October. The proportion has risen from 12% a year earlier to 35%, with the weakness concentrated in London and southern England.
Across London and the South East, 85% of homes are in areas experiencing price declines. Yet the average UK property price remains 0.8% higher annually, illustrating how a positive national figure can coexist with much weaker local conditions.
The report also records 7% fewer sales agreed over the latest four-week period than a year earlier, alongside 7% more homes available for sale.
The price index covers the period to the end of September. These are local market measures, not a finding that every home within those areas has lost value.
For someone moving home, the financial consequences can run in both directions. A lower price on the property they want may be welcome. A lower offer on the property funding their deposit may be less helpful.
Buyers Have More Choice, but Many Are Sellers Too
A buyer with no property to sell can assess an offer against their cash and borrowing capacity. A home mover must also consider what happens to the proceeds from their existing home.
That creates a tension in negotiations. A household may welcome a reduction in its next purchase while resisting a similar adjustment in its own sale.
The important number is often the gap between the two transactions, rather than either price considered alone. If both properties become cheaper, the move can still become more affordable—or require more borrowing—depending on the relative changes.
The national figures cannot settle that calculation. A family moving between different regions, property types or price brackets may experience very different conditions on each side of the transaction. The relevant evidence is what comparable properties are actually achieving in each local market.
A National Average Cannot Set Your Moving Budget
Zoopla’s figures describe a market becoming more geographically divided. An individual sale price still depends on location, condition, competing supply and the buyers available for that particular home.
For mortgage planning, an updated estimate of achievable sale proceeds is more useful than applying a national percentage to the property.
A £75,000 Price Reduction Can Change the Next Mortgage
Consider a hypothetical homeowner expecting to sell for £1.5m, repay a £500,000 mortgage and buy a £2m replacement. Before transaction costs, the original plan provides £1m of equity and requires a new £1m mortgage.
If the existing home sells for 5% less, the sale price falls to £1.425m. With the same mortgage to repay, the available equity falls to £925,000.
If the replacement still costs £2m, the required borrowing rises to £1.075m. The seller’s £75,000 reduction becomes a £75,000 increase in the next loan unless they provide additional cash or change the purchase budget.
| Measure | Original plan | Sale price falls 5% | Both prices fall 5% |
|---|---|---|---|
| Existing home sale price | £1,500,000 | £1,425,000 | £1,425,000 |
| Equity after £500,000 mortgage repayment, before costs | £1,000,000 | £925,000 | £925,000 |
| Replacement purchase price | £2,000,000 | £2,000,000 | £1,900,000 |
| Mortgage required before costs | £1,000,000 | £1,075,000 | £975,000 |
| Mortgage relative to purchase price | 50% | 53.75% | Approximately 51.3% |
The third scenario illustrates why falling prices are not automatically bad news for someone moving up the market. A 5% reduction on the more expensive property saves £100,000, exceeding the £75,000 reduction on the sale.
The mortgage requirement falls £25,000 below the original plan. However, the loan-to-value ratio is slightly higher because the replacement property is also worth less in the illustration.
Borrowing amount and loan-to-value therefore need separate attention. A smaller mortgage does not necessarily place the applicant in a lower LTV band.
Equity Can Fall Faster Than the Property Price
In the same example, a 5% reduction in the sale price cuts equity from £1m to £925,000 before costs—a 7.5% reduction.
The reason is that the mortgage balance does not fall automatically with the property value. The price movement is absorbed by the owner’s equity.
For households with higher borrowing relative to their home’s value, a similar percentage change in price can have a larger proportional effect on their equity.
That does not mean a price fall automatically creates negative equity or forces a sale. It does mean an estimate prepared months earlier may no longer provide a reliable deposit figure for the next purchase.
The calculation should use a realistic sale range, an up-to-date mortgage redemption estimate and the actual costs of moving.
Has Your Expected Sale Price Changed?
Willow can reassess the move using revised sale proceeds, the proposed purchase price, available cash and current mortgage options. That helps establish whether the existing plan still works or needs a different borrowing amount or budget.
Review Your Home-Move Financing →A Cheaper Property Can Still Mean a More Expensive Mortgage
Negotiating a purchase reduction helps, but the monthly cost also depends on the mortgage rate, term and repayment structure.
For a simple illustration, £1m of interest-only borrowing at an assumed annual rate of 4.5% costs £45,000 a year in interest. A smaller £975,000 loan at 5.5% costs £53,625.
The second loan is £25,000 smaller but costs £8,625 more a year in interest. These are hypothetical rates, not available offers, and the comparison excludes fees. Capital remains outstanding on both loans.
A repayment mortgage would have a different payment profile because each payment also reduces the balance. Extending a term can reduce monthly payments while increasing the total interest paid, so the monthly figure alone does not settle suitability.
This is why the purchase negotiation and mortgage assessment should progress together. A revised price may improve the transaction without restoring the monthly budget the buyer originally had in mind.
The Lender’s Valuation Can Change the Cash Required
A buyer and seller agreeing a price does not guarantee that the mortgage lender will accept the same valuation for lending purposes.
Suppose a buyer agrees to pay £1m and expects a £750,000 mortgage, equivalent to 75% of the purchase price. If the lender values the property at £950,000 and limits the loan to 75% of that valuation, the maximum on that basis becomes £712,500.
The buyer’s contribution towards the unchanged £1m price would rise from £250,000 to £287,500: an additional £37,500 before costs.
The actual outcome depends on the lender, product and application. Possible responses might include renegotiating the purchase, contributing more cash or reviewing another suitable financing arrangement. None should be assumed available before the case is assessed.
A valuation difference is also useful information about the transaction itself. The objective should be to understand the property and the financial commitment, rather than simply finding a way to borrow the original amount.
Buying Before Selling Requires a More Cautious Exit Assumption
Homeowners who have found their next property before selling face a separate timing problem. Substantial equity can exist on paper while the cash needed for completion remains unavailable.
Willow’s recent reporting on longer selling periods for £2m-plus homes examined this gap between property wealth and accessible funds.
Where bridging finance is being considered, the repayment plan must accommodate the possibility of a slower sale, a lower price or both. Interest, fees and existing secured borrowing all reduce the amount ultimately left from the sale.
For illustration, an additional three months at an assumed £5,000 monthly financing cost would consume another £15,000. That is a planning example, not a bridging quotation, and other costs could apply.
An extension or replacement loan should not be treated as a guaranteed fallback. Depending on the circumstances, a coordinated sale and purchase, a delayed completion or a temporary rental arrangement may provide a more sustainable route.
Test the Move Against a Lower Sale Price and a Longer Wait
A useful financing assessment asks whether the transaction still works if the existing property sells below the initial expectation and takes longer to complete.
If that scenario creates an unaffordable commitment or leaves too little cash, the purchase budget or timing needs attention before contracts are exchanged.
Downsizers Face a Different Calculation
A falling market does not affect every move in the same way. Someone moving to a less expensive property may release less capital even if both properties fall by the same percentage.
Take a hypothetical sale at £1.5m and replacement purchase at £750,000. The difference is £750,000 before debt and transaction costs. If both prices fall by 5%, the difference narrows to £712,500.
The replacement is cheaper, but the more expensive home has lost more pounds in value. The amount released falls by £37,500.
That matters where the expected proceeds are intended to repay borrowing, support retirement, help children or fund another investment. Those plans should use the cash likely to remain after completion, rather than the headline sale price.
Prime Property Still Needs a Local Assessment
Broad weakness can coexist with demand for particular locations and properties. Willow’s recent coverage of London’s £10m-plus market explored how activity at the very top can differ from the wider prime market.
Neither a strong individual sale nor a weak national headline establishes what another home will achieve. Sellers need relevant comparables and realistic advice on competing stock. Buyers need to assess the property they are acquiring and the borrowing available against it.
For larger mortgages, that assessment may also involve business income, bonuses, overseas earnings or other financial commitments. A substantial deposit remains only one part of the application.
The Moving Budget Needs to Reflect Both Transactions
Zoopla’s latest figures strengthen the case for reviewing home-move budgets as negotiations develop. Greater choice may help buyers secure a better purchase price, while weaker sale proceeds can change how that purchase is funded.
Before committing, establish a realistic range for the existing home’s sale price, the mortgage balance to be repaid, the costs of both transactions and the cash reserve required afterwards. Then assess the proposed borrowing against current income, commitments and lender requirements.
Willow can bring those elements together in a residential mortgage review, coordinating with the estate agent and solicitor where appropriate. The outcome may be a suitable mortgage, a revised purchase budget or a decision to wait.
The latest data do not provide one answer for every home mover. They make it more important to calculate the move using the prices and financing actually available to that household.
Frequently Asked Questions
Falling house prices, available equity and financing your next home.
Does the research mean 35% of individual homes have fallen in value?
No. The figure refers to the share of UK homes located in postcode areas recording annual price falls. It does not establish the price movement or achievable sale price of every individual property.
Can falling prices make moving to a larger home cheaper?
Potentially. If a more expensive replacement property falls by the same percentage as your existing home, the cash difference between the two can shrink. Mortgage rates, available equity, transaction costs and lender affordability still affect whether the move is viable.
What happens if my existing home sells for less than expected?
Recalculate the cash left after repaying the existing mortgage and paying sale costs. A lower sale price may require additional savings, more borrowing, a lower purchase price or a revised budget. Additional borrowing remains subject to lender approval.
Will the lender automatically accept my negotiated purchase price as the property value?
No. The lender obtains its own valuation assessment. If the accepted valuation is below the purchase price, the available mortgage may be lower than expected and you may need a larger cash contribution or a revised agreement.
Could bridging finance help me buy before selling?
It may be appropriate in some circumstances, but requires a credible repayment strategy and an assessment of interest, fees, existing debt and the effect of a delayed or lower-priced sale. It is not automatically suitable simply because there is equity in the existing home.
