Over the last 15 years the number of new homes built in Britain is equal to the number of new homes under private rental. In other words, buy-to-let is in effect taking all new homes (though obviously some existing homes are going into btl and some new ones into owner occupiership so it's not a 100% match).
But there have been vast rises in the number of private tenancies, sharp falls in the number of owners with mortgages, and the consequences are many, from tattier streets (landlords don't spruce up homes with sitting tenants, the tenants don't want to plant the gardens because they might be kicked out next year) to families having to move house mid-school year because the landlord is kicking them out.
Today it's announced that the number of people made homeless from private tenancies has trebled in five years, and that private landlords are now the leading cause of homelessness. www.bbc.co.uk/news/uk-27940701
AIBU to think that this has resulted because of all the people piling into buy-to-let because it is deemed as more attractive than the alternatives (bank accounts, shares, small business, etc.), and that therefore we need new taxes to make buy-to-let far less attractive, given the social problems it causes?
