"Besides which in the majority of cases why would an investor want to provide a new home to tenants?"

Exactly I totally agree. Thats why they would be an existing home. Given the home already EXISTS it does not add to supply of homes to rent. It merely just increases their value as they have been bid up by the property investor. This makes hosuing less affordable yet the government was to make them more affordable. Well the had there chance with this new housing scheme that brings more SUPPLY to market thus theoretically lower prices. But why not tax deductable??
