For some years now, many buy-to-let landlords have stayed with their existing mortgage lenders, many of them paying standard variable interest rates.
This inertia has mainly been fuelled by a lack of supply of alterntaive buy-to-let products, combined with low rates making remortgageing impossible or undesirable.
However, more buy-to-let lenders have returned to the sector, and a number of new players have entered the market, substantially increasing product choice.
What's more, with interest rates set to rise next year, more and more buy-to-let landlords are now looking at moving to anew deals - possibly fixed rates.

You will probably end up arranging your next buy-to-let mortgage or remortgage through a broker.
But there is no harm in being as well-informed as possible before you even approach an adviser.
