Following changes to mortgage interest tax relief, many buy-to-let landlords have either switched their portfolio to a limited company structure or at least are purchasing any further properties this way, rather than in their own name. There can be tax advantages of doing so, although you should always take specialist tax advice before taking the plunge.
More lenders are offering mortgages for limited companies than in the past, so rates have fallen and there is more choice available. AWS Financial Services has strong relationships with all the main buy-to-let lenders, as well as some specialist providers, so can help find the right mortgage for you, whether you are buying or refinancing via a limited company structure.
