Hi, I need advice as a landlord on a house I rent out in a rent pressure zone area. The house is rented out for less than half of what I should be receiving every month. This is going on years and now with my mortgage gone up a few hundred a month I just can’t leave it the way it is. I rented the house to 1 person and it is a 3 bed house. Can I rent out another room in house? Otherwise I will have to give notice to tenant that I intend on selling. I don’t want to sell but feel this maybe only way out. Thanks for any advice
