Lenders have traditionally been reluctant to offer buy-to-let deals on dwellings for immediate family members, because they require Financial Services Authority regulation - but as the market gets ever more competitive, some lenders are introducing some flexible tailor-made products.

One such example comes from the Britannia Building Society, who have just launched a new range of mortgages available for those investors who intend to rent property to close family members. This is Britannia's first buy-to-let product range, which includes two and five year fixed rate deals and a lifetime tracker.

The Scarborough Building Society also offer a comprehensive range of mortgages for the student buy-to-let market, including two and three year fixed rate deals and a variety of flexible options. All these products have an 80 per cent loan to value.

The Clydesdale Bank is one of a rare breed of lenders supplying a student offspring buy-to-let product (that is only available through mortgage brokers), which currently has a reasonable starting rate of 5.29 per cent. The rate, which is the same for the life of the loan, tracks at 0.79 per cent above the Bank of England base rate.
