No, I'd rather see more enlightened planning policies introduced, where 1/3 of all new builds must be self builds (which would make plots of land more affordable and would mean buyers weren't paying developer's premiums, and also help the situation of developers sitting on land banks waiting for planning permission while perfectly good land is doing nothing.
I'd also rather see higher inheritance tax, because that is the main reason house prices are so high, and it doesn't reward the personal endeavour of the individual in the way that hard work does, but rather their random fortune in having wealthy parents.
I'd rather not drive out second home owners per se by making it cheaper for them to take their money and taxes abroad.
Oh, I'd also like to encourage first time buyers to buy small flats needing a bit of work first, rather than expect to move into a 3 or 4 bedroom house straight away. I still remember buying a semi detached house in a popular commuter village for £20,500 7 years ago because none of the locals wanted it as it needed work done.
