Absolutely, as well as a realtor. Like anything, there is a cost associated with this service, but the good thing is they usually screen them for you, and obviously they can market to a lot more people. My advice would be to go to a realtor first before a property managment company.
A property management company could help find tenants but charges steep fees. A better option is to list in the local classifieds, bulletin boards, at universities and colleges, and through word of mouth. You may have to reduce the rent to be competitive. You could even tell friends you would pay a referral fee for each renter, which is cheaper.
Property management companies take a cut of the rent in order to find tenants and maintain property. They are financially motivated to find tenants for your property. You would lose some of the profit from your property but you would also lose some of the headaches of being a landlord.
A property management company will help you find a renter, but they generally charge for helping you. In some cases, they require you to sign a property management agreement first.
