Boston Property Market: House Prices, Sold Data & Development Finance, Q3 2026 Review

Boston: Fenland market town with waterfront regeneration potential and agricultural sector employment.

The Boston property market recorded 1,079 residential sales in the 12 months to 30 June 2026, with a median sale price of £190,000. This places Boston £31k below the Lincolnshire county median of £220,500, and £95k below the approximate UK median of £285,000.

Prices in Boston have recorded a moderate decline, a year-on-year change of -4%. Within Lincolnshire, Boston ranks 7th by price out of 8 principal towns, and 7th by transaction volume.

On a quarterly view, Boston median prices moved from £188,000 in Q4 2024 to £195,000 in Q1 2026, a change of +3.7% over 5 quarters. The most recent quarter is excluded because HM Land Registry registrations for it are still incomplete.

The local planning authority for Boston approved 7 residential planning applications and refused 5 in Q3 2026 (1 July to 30 September 2026), with 32 still awaiting a decision. Too few decisions were captured in the period to state a reliable approval rate. Planning figures come from local planning authority records compiled by Landstack, retrieved on 3 October 2026. Councils and Landstack can take several days to publish decisions, so decisions made in the final days of Q3 2026 may not all be included yet.

Schemes approved in Q3 2026, together with those still awaiting a decision, propose around 250 homes, an estimated £46.2m of development value at local sale prices. Treat the unit total as an upper bound, since an outline permission and its reserved-matters application both count.

Property prices in Boston vary significantly by type. The table below compares Boston prices with Lincolnshire county averages and UK national figures.

Detached homes in Boston command £255,000, while flat properties are most accessible at £90,000. The £165k spread between the most and least expensive types indicates a relatively compressed market where margins between types are tighter.

HM Land Registry has so far registered 97 new-build sales in Boston for the past 12 months, 9.0% of registered transactions. New-build sales are typically registered 6 to 18 months after completion, so this understates current delivery and is not a completions figure.

On those registered sales, new builds in Boston sold at a premium of 34.9% to existing stock.

Across the wider Lincolnshire market, 656 new-build sales have registered so far. See our Lincolnshire property market report for the full county picture.

For developers considering Boston, the local market data translates directly into finance structuring. With a median value of £190,000 and detached homes at £255,000, lenders can assess scheme viability with confidence.

A typical development finance facility for a scheme in Boston with a GDV of £255,000 would attract senior debt of approximately £165,750 at 65% LTGDV. Mezzanine finance can stretch total borrowing to 85-90% of costs, while bridging loans enable rapid site acquisitions completing in as little as 5 working days.

While prices have softened 4% year-on-year, experienced developers can still generate strong returns in Boston by targeting well-located sites with clear demand drivers.
