House-price headlines can make moving home feel like a decision that needs perfect timing. But the latest figures are more useful as a prompt to review your plans than as a signal to rush or put everything on hold.
In its report released on 1 October, Nationwide said annual UK house-price growth slowed to 0.8% in September 2026, from 1.6% in August. Here is what that could mean when you are buying a home or reviewing your mortgage.
Slower growth does not mean prices have halved
The rate of annual growth has halved, not the value of homes. Nationwide also reported a 0.2% monthly fall after seasonal adjustment. These are national measures: they do not tell you what a particular property is worth or guarantee what prices will do next.
Buying? Start with your budget, not the headline
A sensible starting point is to compare the asking price with evidence of similar local sales, consider the property’s condition and work out a monthly payment you would be comfortable maintaining. A quieter national market is not proof that every seller will accept a large discount.
Keep money aside for legal costs, a suitable survey, moving expenses, any applicable property tax and an emergency buffer. For those buying their first home, our first-time buyer mortgage guide explains how to prepare a workable budget before committing.
Remortgaging? Check the valuation behind your deal
Your loan-to-value, or LTV, compares your mortgage balance with the property’s value. A different valuation can therefore change the mortgage options available, even when the amount you owe has not changed.
For example, a £300,000 mortgage against a £400,000 property is 75% LTV. If that same property were valued at £375,000, the LTV would be 80%. This is an illustration of the calculation, not a prediction about house prices or a mortgage offer. The lender’s assessment matters more than applying a national percentage to your own home.
Give yourself time to compare
MoneyHelper recommends starting to shop around at least six months before a fixed or discounted deal ends. Reviewing early does not mean completing a switch early: check any early repayment charge and the timing of the replacement deal.
Compare the total costs, fees and features of staying with your current lender against moving to another. The lowest headline rate is not the only consideration. Our remortgage guide explains the questions to work through.
What should you do next?
Use the news to revisit your figures, not to second-guess the entire market. Speak to TLA Finance about your plans, available deposit or equity, and mortgage end date so the options can be considered in the context of your circumstances.
Your home may be repossessed if you do not keep up repayments on your mortgage.
