Sergei "Well, if the property wasn't allowed to be purchased by investors - that would sink the economy, which would result in the vast majority of people being unable/unwilling to purchase the property due to their economic situation regardless of the housing price, either due to capital or fear of the uncertainty in the economy. They almost certainly couldn't afford to renovate the property in that circumstance. Thus, the houses would fall into disrepair either way. I also think there is something rather dreadful about wishing on an economic crisis, but other posters have pointed that out to you."
Sorry, Sergei, but that makes no sense! If an investor wasn't buying it, a homeowner occupier would!
Why do you think there is 'a vast majority of people being unable or unwilling to purchase that property'? There are many, many people in private renters who are more than able to pay what should be their mortgage repayments on the house they live in, but instead are being made to pay out more in rent, thus preventing them from saving the deposit.
Why? Because you used your equity in a property you bought, possibly via the same good fortune I outlined earlier in my case, to snap up that property.
Where have I said I 'wish an economic crisis'? I have said that the government should stop artificially propping up house prices. If you think that will bring about a financial crisis, you've laid your own argument bare; namely conceding that it's just this government's intervention that is keeping the whole swaying, teetering edifice of madly over-priced housing (and the BTL phenomenon) upright. Not a great way to run an economy.
