How do mortgage rates affect supply and demand for houses in the UK?
Mortgage rates affect supply and demand in the UK housing market by influencing buyer sentiment and appetite around borrowing.
Higher mortgage rates increase monthly payments for buyers. In response to those higher rates, buyers might increase the term of their mortgage or look at cheaper properties. Alternatively, they might delay their purchases or shift to renting, reducing demand and slowing transaction levels.
Interestingly, any period of uncertainty around rates is likely to cause buyers to pause. Even if rates go up, once they stabilise again, consumers tend to return to the market having adjusted their plans in line with the higher rates.
Similarly, if there is potential for a drop in mortgage rates, transaction levels will slow as consumers wait for a more certain outcome. Consistent lower mortgage rates may reduce monthly payments for some borrowers and could support buyer demand, although the impact will depend on individual circumstances and wider market conditions.
It is important to note, however, that a large number of UK property sales take place out of necessity. These do not get delayed as a result of changing rates. Similarly, around a third of all UK property transactions are made by cash buyers, so are not affected by mortgage rates.
Housing supply responds more slowly to changing rates. Higher mortgage rates can reduce the supply of new houses by making it more expensive to develop them, although existing stock may stay on the market longer.
