Rental housing is not usually offered by Realtors or real estate agents here. I know it’s unlike most parts of the U.S., but here most houses, townhouses, or condos which are available to rent or lease are offered “for rent by owner”.

Please beware that there are many scams around rentals. Be extremely careful! Some scams ask for money upfront, before you can even see the property. Many of these homes are actually for sale, so Google the address to check.
