The valuation, and every comparable behind it
3 of 100 pulled comparables drove the valuation, with a matched median of £172,000. The price per square foot cross-check implies £96,101 for this floor area.
This valuation is based on 15 recently sold properties near this 1-bedroom Flat (378 sqft). 12 sales were excluded from the pool as they belonged to a different postcode sector with a materially higher price-per-sqft than the subject's local pocket (DY1 2J). This avoids pulling the valuation up against a different micro-market. There were no nearby flat sales in sufficient quantity to value directly, so we identified 1 flat sale in the wider area to establish a price-per-sqft benchmark. With limited same-type sales available, we calculated the price per square foot across the best-matched nearby sold properties and applied that rate to this property's floor area of 378 sqft. Notably, 4 sales were on the same road as this property (50, Osprey Drive, 786 sqft, £180,000 and 91, Osprey Drive, 764 sqft, £105,889), providing a highly relevant price anchor. Post-refurb ceiling: the valuation was capped at £350/sqft, which is 1.6x the median price per sqft for the subject's postcode sector (DY1 2J). This prevents comps from adjacent higher-priced micro-markets from distorting the final number. Confidence reduced. Based on these comparables, a refurbished 1-bedroom flat (378 sqft) in this area is valued at £95,691. This is the median of the comparable evidence, the point at which half the comparable sales sit above and half below. Confidence: high. The purchase price is £45,000, which is £50,691 (53.0%) below this post-refurb valuation. This gap represents the potential uplift from purchasing below market value and refurbishing. The comparable sales confirm the market supports a higher price once the property is brought to a good standard. Sanity flag: GDV is more than 2x the asking price (2.13x). Either the asking is materially below market or the comp pool is skewing high. Worth a manual cross-check.
