I would like to raise them, They have been living there for approx 22 years. Its a private 3 family, Its not rent controlled/stabolized. Their lease has been up for over 1 year. I am giving them 60 days notice for the rent increase. I am in brooklyn, N.Y. I will provide them with a letter for the rent increase and its explanation in expenses- is there anything else I need to do? Thank you.
