Whether you are looking to buy or sell a property in Grantham or are exploring investment opportunities in the area, understanding the latest property market trends can help you to make informed decisions. In this blog, we look at the performance of the Grantham property market across the key areas including price trends, rental market and supply vs demand.
Overview of Grantham’s property market trends
According to Rightmove, average sold prices for properties in Grantham were down 3% in the last year. Many areas of the UK have experienced similar average decreases in sold prices, largely due to the stamp duty changes introduced in April 2025 causing volatility in the housing market.
Across the South Kesteven authority, private rents stayed around the same over the year, with an average monthly rent of £830. According to Rightmove, the average property price in Grantham over the last 12 months was £227.393 considerably lower than the average price in nearby Stamford, which was £354.025
How demand and supply are shaping prices
There is higher demand than supply across Grantham and wider South Kesteven, with the South Kesteven District Council addressing the housing concerns through the Housing Strategy 2026/2031. The strategy includes plans for 18,000 new homes to be delivered by 2036.
The imbalance between supply and demand drives house prices up, as competition amongst buyers intensifies in areas where there is a low number of properties on the market.
