A perfect storm of Government changes has been brewing for buy-to-let investors over the past year. The Government's 'crackdown' on private landlords has already begun to drive some away from the sector and has limited money-making potential for others.

Investors are still adjusting to the three percentage point stamp duty surcharge for “additional properties”, applying from April 2016.

The removal of tax relief on mortgage interest for higher-rate taxpayers, having only just started from this April, poses a great threat over a coming years.

On top of that are tighter rules governing lending to larger-scale investors, which come into play tomorrow. Any attempt to control rents would likely crush returns further and make it even harder to obtain finance, landlords claim.

Labour leader Jeremy Corbyn stoked the fires even further at the party's conference in Brighton last week, hinting the party would bring back rent controls if it came to power.

The bulk of the Government’s changes hit only those operating privately, with limited companies largely unaffected. But it has created a myriad questions for many landlords, from those with one solitary rental property, up to those with a sprawling empire of buy to lets. Several have outlined their problems to Telegraph Money.
