The street in brief

Sales on William Street are mostly terraced houses. The median sale price is £86,000, about 40% below the typical SA9 sale. Per square metre of floor space it comes to about £1,087, below the district's £1,576. Recent sales are too thin to call a trend for the street itself; SA9 prices as a whole have been rising. With 26 sales across 18 homes since 2000, homes here come to market only rarely.
