To be honest id really like to see a law passed putting a cap on the number of investment properties people can own. Someone buying a couple to retire off the income is one thing, some **** buying a hundred or so to bilk the public id obscene.
Other than that, remove greenbelt restrictions, disband any council that doesn't reform their planning laws to allow people to build what they want and so on.
Threatening to nationalize any bank that partakes in price gouging would be nice as well. Charging 9% on a mortgage is absolutely obscene. Here, ASB is charging 8.5%. Imagine paying that on a $1mn mortgage (not a very big one either). i dont know what the mortgage regs are back in the UK these days but one here is that you need a 20% deposit and a thorough examination of your finances to show you can afford double the mortgage repayments, on a small mortgage of half a million that makes a deposit of 100k and rough repayments of about 6k a month.. more than most people earn. Yes 2008 was unfortunate but various governments responses to that has simply priced any normal person out of it for some rubbish excuse about 'fiscal responsibility'.
Then again, much of this can directly be attrivuted to governments *****y policies. Be it jacking interest rates after they caused inflation, selling off housing and not building any more, introducing (and removing) too many regulations etc. etc. etc.
