Pugh & Co's June auctions in the north sold more than 120 properties, generating £11.3m.
North West lots included three nightclubs, a police station and several plots of land.
The largest auction of the month was held at Manchester's Old Trafford ground, where 80 out of the 115 properties offered were sold, generating sales in excess of £7.2m.
The former Kiss nightclub in Oldham went under the hammer at the Manchester auction, exceeding its guide price of between £75,000 and £85,000 to sell for £100,000.
The former Chipping Police Station, Preston, sold for £15,000 more than its guide price at £215,000.
A lot comprising two parcels of land at the Indigo Works industrial estate in Ellesmere Port sold for more than four times its guided price at Pugh's Liverpool auction. Guided at between £10,000 and 20,000, it sold for £65,000.
Pugh's residential arm, The Auction People, sold a vacant six bedroom semi-detached house on Danes Road, Rusholme, for £215,000. It had a guide price of between £140,000 and £160,000.
Paul Thompson, director and auctioneer for Pugh and The Auction People, said: "We had a number of sales leading up to each event and interest remained high at all venues when we started to sell in the room.
"It was a great overall turnout and it was clear that many of the people were there with the intention of buying.
"Vacant land, renovation projects and buy-to-let opportunities seem to be the biggest draw for buyers across the North West as people look to build their property portfolios and start investing in the future.
"We are already taking instructions from across the region for our July auction which looks set to be another successful event."
The closing date for Pugh and The Auction People's July auction is Wednesday 19 June.
