Next Steps After Parent Passes Away?

Location: Texas

i don't know if this is the right sub for this, if not please direct me to a better one.
but long story short, my dad passed away in Texas almost a month ago, i wasn't made aware until Oct 19th. him and i weren't very close but i'm his closest living family member and oldest child therefore next of kin.
i have made the arrangements for his cremation and death certificate, i now will have to travel down there (i live in a different state) and do all the necessary next steps.

my question, he was living in an apartment and to my knowledge was in the process of being evicted from it, do i contact the property management in order to have access to his apartment to get his belongings? is there a time frame? i was told that the Investigators would have access to it but don't know if i have to also go through the property management due to the eviction.

and second, his bank accounts and whatever vehicle he had. like i said we weren't close so i have no idea much about any of his personal stuff. how do i go about figuring out what accounts he had with who, and what vehicle he had at the time?

i also have no idea if he had anything set up such as a will or anything like that. how would i go about finding that out?

sorry if this is confusing at all, i've never had to deal with this before and it was a completely blindsiding death so i have no idea what to do next. thank you for any information. and if there's anything i'm forgetting that needs to also be done please let me know.
