Some rentals will not pay a real estate agent a commission and many real estate agents will only show properties where they will get a commission. If properties are being shown by the owner or it is an apartment corporation a commission they may not agree to be pay. Wouldn’t completely depend on a realtor unless you are looking for a higher cost property (home or condo usually). Do your own looking as well. If you sign a contract with an agent make sure there is a clause describing what happens if you find your own rental. You need to make sure you won’t need to pay the agent if that happens.
