[Reincarnate]

if you really are 'wealthy' then you should be able to find a place that doesn't have a shitty landlord, making it a relative non-issue (e.g. a reputable doorman building)

if you're living with roommates, get together at the very beginning and discuss *all* the possible ground rules you can think of. it's easier to talk about everything now under the umbrella of "rule discussion" than it is to bring up an awkward conversation later when shit hits the fan and people get passive-aggressive (some big ones to discuss: bringing guests over/girlfriends/fridge and kitchen usage/bathroom and shower timing slash cleaning slash dishes/how furniture will be split if applicable/taking out trash/volume level for stuff like music and whatnot/blahblahblah/etc). Most of it is pretty common-sense, but it's still good to just get all that shit out of the way ASAP.

don't ship anything valuable -- take it with you instead.

don't be one of those dumbass roommates that leaves the AC/heater on all day and jacks up the utility bill for everyone else

find a good balance between doing the dishes often enough to keep loads light/easy to manage, but not so often that you're wasting water/power/heating, as dishwashers are quite heavy on the utility cost

do laundry often and don't let it just sit there in a hamper for eons at a time

l2cook if you can
