Tips:
1.) Read the lease. You probably have to notify them early that you are not renewing, or they can automatically renew you, or charge fees for not telling them. 2.) Never expect your deposit back. Consider putting your last month's rent into escrow until they refund your deposit. The NY Bank of Mellon offered this service at the time. 3.) Expect neighbors to complain if you have a dog, even if they are not loud or rambunctious, so see if you qualify to get an emotional support animal prescription to negate most legal issues. 4.) Things will break, document them in writing, use their "buildinglink" or whatever property management software they use today, but take screenshots and document it for your own records, including in email, so they can't delete it on you and say you didn't tell them. 5.) Every large landlord is a financial services business trying to extract fees out of you for everything they can think of to make a profit. They are the fast food of housing. Low labor costs, low expectations, not good for you in the long term. You should try to find a home to buy at some point to avoid enriching their shareholders.
