In the United Kingdom, buy to let mortgages investment have traditionally been very lucrative. However, major tax increases in stamp duty and income tax have reduced the net income from buy-to-let assets in recent years. An extra 3% stamp duty tax is applied to the entire selling price of a second or subsequent property. As a result, buying a buy-to-let property is typically more costly. A ban on the deductibility of mortgage interest against rental income has also boosted the levy on rentals. This will result in a tax bill that reduces the net profit on rental income. For those with low levels of gearing who have already acquired their assets or who keep their buy-to-let mortgages portfolios in a Limited Company, returns might be higher.Â
