Read the lease agreement first and ask questions, before signing.
Check that everything is the way you want it to be.
Repairs/improvements noted during your property visit - should be written in and fixed.
Landlords do replace bad carpeting, bathroom doors and do other expensive improvements to the property that you wouldn't think they do - because a good landlord wants the tenant happy and staying for a long time...
Take pictures of scratches, dents broken tiles, furniture issues (if furnished), with the date on them,
before moving in.
Check if the property is offered or about to be offered for sale, the owner is current on his condo maintenance fees (or you may loose access to the gym etc.), the owner is current on his mortgage...
It's hard to predict anything in life, but these preventive measures will make your life easier in the future.
