Valuation
The most recent sale price indexed forward to today's value is £104,703. This is one data point to inform the valuation. Another method is the valuation implied by what comparable homes are selling for. Homes in Boston are now selling for between £1,240 and £2,020 per square metre (£115 and £187 per square foot). Based on an internal area of 70 m², this implies a valuation between £87,000 and £141,000. Treat this as context only.
