Homes account for the biggest share of whole belongings held by the UK family sector. Households’ spending and saving choices rely partially on the worth of those belongings. What causes home costs to maneuver can due to this fact have essential penalties for macroeconomic coverage and monetary stability. Our home worth mannequin decomposes actions in home costs into contributions from key financial drivers. Amongst these, measures of actual family revenue clarify a lot of their variation over time. The rise in mortgage charges through the current tightening cycle is estimated to have saved home costs almost 10% decrease than had rates of interest not moved, with a few of this impact offset by actual revenue progress.
The home worth mannequin
Understanding developments in home costs is essential for assessing how adjustments within the housing market might affect broader financial exercise. For instance, actions in rates of interest can weigh on home costs, which might dampen financial exercise by lowering the collateral households have obtainable in opposition to which they borrow. This will then have implications for consumption and funding throughout the economic system. Our purpose is to supply an up-to-date software that may each clarify home worth dynamics over the medium time period and ship strong forecasting efficiency over a three-year horizon, utilizing a easy framework that captures the primary drivers recognized within the literature. We construct on a big inventory of educational and utilized literature that analyses the drivers of home worth progress over time and throughout completely different international locations and areas. Duca et al (2021) present a complete evaluate of this literature.
In principle, home costs needs to be decided by charges of return, much like costs of monetary belongings: over time, one would count on the return to proudly owning a property to align with the price of financing the acquisition of a home (Auterson (2014)). In contrast to the worth of different belongings, or business actual property, the connection between housing prices and anticipated returns could also be imperfect due to the intrinsic worth housing offers within the type of shelter. And in contrast to in monetary markets, transactions within the housing market are much less frequent and face extra frictions such that changes might be slower.
Our empirical illustration builds on Auterson (2014) and follows an error correction set-up to seize the dynamic changes within the housing market over time. It hyperlinks short-term home worth progress in actual phrases to adjustments in common rates of interest on new mortgages and progress in measures of actual family disposable revenue. We assume that over time, home costs converge to a long-run equilibrium pinned down by measures of family assets (revenue, wage share of revenue), the extent of mortgage charges and housing provide (whole housing inventory divided by inhabitants).
To estimate our mannequin, we use an economically related pattern (1991 to 2023). We thereby keep away from the structurally very completely different housing market previous to the Nineties with decrease possession charges and a special regulatory and tax regime. We do seize the change in financial coverage regime from 1997 and embrace the Covid interval to cowl current developments. The mannequin performs properly at forecasting home costs, notably through the aftermath of the worldwide monetary disaster (GFC) and lately. The mannequin focuses on statistically and economically related determinants of home progress, which permits us to interrupt down adjustments in home costs into the contributions from completely different financial drivers.
The drivers of home worth progress
Via a decomposition of home worth progress, we achieve helpful insights. We discover that actual revenue progress explains a lot of its variation over time. That is per earlier evaluation of the UK housing market which additionally finds that family revenue is a vital driver of home worth progress (eg, Meen (2013) and Auterson (2014)). Chart 1 reveals a historic decomposition utilizing the mannequin’s estimated parameters and historic realisations of home worth determinants. Measures of actual revenue progress (orange bars in Chart 1) clarify many of the home worth growth pre-GFC in addition to a number of the weak point in home costs within the years that adopted.
Figuring out the position of housing provide impact is harder in a UK-wide specification, given the position of native constraints, planning frictions, and structural and cyclical variations throughout areas. Consequently, our indicator of provide, based mostly on housing inventory and inhabitants dynamics on the combination stage, provides solely little or no info to the mannequin (yellow bars).
Increased mortgage charges (purple bars) have a damaging affect on home worth progress. We will see that inside mortgage charges, the rise in spreads over risk-free charges drove a number of the decline in home costs through the GFC whereas the loosening of financial coverage thereafter supported home worth progress. Whereas the long-term decline in risk-free charges till the late 2010s on common supported home worth progress, as mentioned intimately by Miles and Monro (2021), the rise in Financial institution Charge since 2021 explains many of the weak point lately.
The residual (pink bars) captures adjustments in home costs that can’t be defined by the home worth mannequin. It’s notably massive through the GFC, suggesting that the affect of falling incomes and widening mortgage spreads might have been amplified by banking sector difficulties. The ‘race for area’ throughout Covid most likely explains a number of the constructive residuals in 2020–21.

Mannequin implications
One function of the home worth mannequin is that we are able to use it to watch financial transmission through the home worth channel, which has implications for impacts of financial coverage on the broader economic system.
When assessing the direct affect from Financial institution Charge on home costs by mortgage charges, and holding all else equal, the mannequin signifies that home costs reply to a 100 foundation factors rise in Financial institution Charge with a 2.5% fall, which is totally realised after three years. This assumes that adjustments in Financial institution Charge are immediately mirrored by an equal change in mortgage charges.
A change in Financial institution Charge may have an effect on home costs not directly, by its impact on family revenue and home constructing but in addition different channels together with enterprise funding (Bahaj et al (2020)). A few of our fashions recommend that these oblique results might be no less than as massive as direct results through mortgage charges.
Over the current tightening cycle, the mannequin signifies that the rise in Financial institution Charge by its direct affect through mortgage charges might have saved actual home costs almost 10% decrease relative to a counterfactual with unchanged rates of interest, abstracting from any extra oblique results. This may be seen by the purple bars in Chart 2. This impact is estimated to have partly been offset by a restoration in actual incomes. As well as, mannequin residuals begin flattening on home costs as early as 2022 Q2 earlier than truly fizzling out for most up-to-date information. It’s doable that the direct affect of financial coverage on the housing market might have been transmitted extra shortly than sometimes noticed within the mannequin’s estimation pattern, though the general peak affect stays comparable.
Falling home costs can dampen family consumption by lowering owners’ internet wealth. This discount in wealth additionally limits the collateral households have obtainable to borrow in opposition to, tightening credit score situations. The mixed impact of weaker consumption and constrained borrowing can weigh on general financial exercise.

Conclusion
This home worth mannequin offers a helpful lens by which to analyse the dynamics in home costs over a number of years and the broader financial situations that drive them. To tell coverage, this mannequin would have to be complemented with different instruments which can be higher suited to watch housing market developments within the close to time period.
To make sure the mannequin stays clear and easy to make use of, it abstracts from many real-world complexities. This contains different doable drivers of home costs like adjustments in mortgage traits, credit score provide situations, family monetary wealth and adjustments in tax and regulation over time. Structural modelling can in additional element converse to causal linkages between financial coverage, housing markets and financial exercise (eg Albuquerque et al (2025)). And regional evaluation of home worth dynamics might higher be capable to choose up the affect of housing provide.
