The Block St Kilda apartment to use online auction tool Gavl on finale night

The Block St Kilda apartment of Western Australian couple Courtney and Hans will have the advantage of using Gavl, the live online bidding app, when it comes to auction night at the end of this month.

Gavl is a digital platform for live bidding and live streaming real estate auctions.

They're likely to receive a wider buyer pool, and would appeal to the more private, interstate and overseas parties.

The auction of the three bedroom, two bathroom apartment at 2/34 Fitzroy Street will be live streamed on Gavl to registered bidders.

Gavl representatives will be on site to announce any bids from the remote buyers as they come through the app.

Courtney and Hans' apartment is the largest at nearly 300 square metres. They decided to create the largest living space in Block history.

The apartment, which won the first room reveal on this years show for its main bathroom, has the lowest price guide among all five apartments at $2.2 million to $2.4 million.

It will be a first for the reality renovation program in Australia, but a winning bidder was found on The Block New Zealand.

Buyer Mike Wyth won the auction, spending $921,500, from his own home.

Gavl CEO Joel Smith said they had great success with The Block NZ purchase.

“We’re thrilled to be helping Courtney, Hans and Wilson Agents when the apartment sells under the hammer in a couple of weeks’ time," he said.

"We had great success when Gavl partnered with The Block NZ this year to enable remote bidding on all the property auctions in the season finale.

"One of the NZ apartments sold to a buyer who was bidding through Gavl – so we’re excited to be a part of the Australian version, and hopefully achieve a similar result.”

Wilson Agents agent Jesse Raeburn, who is marketing the apartment for Courtney and Hans, says it will be a target for investor.

“With strong rental returns prospects and a significant depreciation schedule, this property is a great opportunity for any investor," he said.

"At Wilson Agents, we’ve been using Gavl in our auctions for some time and have been highly impressed with its benefits and convenience for all parties – particularly among investors.

"As a result, we didn’t have to think twice about using Gavl for this auction on The Block, as our past experiences have shown that it will draw a greater bidding audience and thereby help increase the sales price."

On average, auctions streamed via Gavl attract 47% more viewers than traditional auctions – maximising the sales potential of properties
