Banning and high taxing is always the "solution" given by many - it isn't. As you will see from my posts I am from a very popular tourist area. I could have the mindset many have shown on this thread or the numerous others there are of the "bash second home owners/holiday lets" that frequently appear but I am not, I am realistic as to how areas survive. If tourism did not exist here, there only other main income generation is hill farming - it is not enough to sustain the area.
Too many of friends and family will happily sell a property at high prices to non-local folk, then complain there are not enough houses for locals to purchase or the prices are too high.
For many rural tourist areas irrespective of tourism there are not enough jobs for locals, so for the younger generation it will mean, if they do not wish to farm or work in tourism they will have to move to other areas, where property is normally cheaper.
As for those complaining about the grants given during covid went to a % of people who didn't live in the UK but had a second home here, it was how the rules worked - we did not receive any grants as we own a company and therefore were deemed we somehow fiddled the tax system using dividends, so like others we struggled to pay the mortgage. Was it annoying to see plenty of others receive money, yes but in life you just get on with things and do your best to protect ones own family.
People are allowed to spend their money on whatever they want, others are allowed to sell their property to whomever they want (unless a s106 or restriction is in place) I certainly do not want to live in a society where an over reaching government thinks it can tell people where they should and should not live - if someone wants more than 1 home and can afford it then fine, someone else would have benefitted from selling it to them at a higher price if in a desirable area.
