They cannot raise your rent until your lease expires. They can then write a new lease and raise your rent and you would have to sign that then, which from what you said sounds like July. Since you have time, you can compare what your new rent would be to what other places are renting for at the moment around you. If raising it by 550 a month is about the same as what other people are charging total than you are, probably just going to have to pay the higher rent. Most landlords raise the rent yearly, especially those that are corporate owned like apartment complexes. Private landlords can vary , some will never raise the rent, and some will always raise it yearly. It’s nice that you have this many months to figure it out, most people only got a notice that the rent is going to be raised 30 or maybe 60 days before hand. You have lots of time to do some research and figure out if the new price in July is worth it or not.
