Birmingham-based Bond Wolfe Auctions said that an increase in bidders from London and the South East helped it to achieve an 80% success rate at its July auction last week.
The company, which was formed in January by former Bigwood auctioneers, raised £10.4m, selling 88 out of 111 lots offered.
Viscount House, a freehold former children’s home offered on behalf of Birmingham City Council, sold for £410,000 from a guide price of £150,000 plus.
A two-bedroom end-of-terrace house in Edgbaston, which had been offered with a guide price of £20,000, eventually sold for £185,000.
Gurpreet Bassi, chief executive of Bond Wolfe Auctions, said: “Not only did we have a packed auction room with 1,500 people in attendance on the day, we also had a record 290 remote bidders, many from London and the South East.
Bond Wolfe Auctions’ next sale will take place on Tuesday 10 September at the Holte Suite at Aston Villa Football Club.
