There’s things you need to consider when letting a property. You can find out what your responsibilities are as a landlord on the government’s renting out a property pages

Portfolio landlords


If you have 4 or more mortgaged Buy to Let properties, you’re a portfolio landlord. You’ll be able to switch to a new product once your existing deal expires (subject to standard criteria), but we won’t be able to offer you a Buy to Let mortgage on a new property.

Paying tax on your let properties
