Barry Shearman was speaking after Labour announced plans to scrap stamp duty for first-time buyers purchasing a property under £300,000, and giving them first access to new-builds.
He praised the policy, but admitted that Labour's proposals to prioritise new-builds for first-time buyers living in area for three years was "difficult", as it could potentially penalise someone looking to move up the social ladder by purchasing a property in a new area.
Meanwhile, 5000 small business leaders urged voters to choose the Conservative Party on May 7th in an open letter to the Daily Telegraph newspaper.
They said the Conservatives had turned the economy around since 2010, and deserve a chance to finish the job in 2015.
All the major parties have pledged to build hundreds of thousands more homes by the end of next Parliament.
Barry Shearman told Premier's News Hour:
"I think that we're getting down into this brit-brat campaign again, and I do deplore it. I wish we would actually start talking about values.
"What I liked this morning is that we recognised that homes is one of the most important things that any person faces, getting a... nice house is a central part of the good life.
"Reducing stamp duty to zero for first-time buyers of homes under £300,000, that's a good, practical step. It'll save a lot of people £5000.
Speaking in light of the first-time buyer priorty, Mr Shearman said: "I think that's the most challenging part of the announcement today. I can see why we've come up with this and I think our heart's in the right place here... I think it's going to be the most difficult one to deliver..."
