Cost of management depends on what services you are looking for. For instance, if you are an out of state landlord you may need someone to collect rent, take calls and make repairs. However, if you seek specific services that are limited, the cost may be a percentage (10%) of the monthly collection. In the event you are trying to lease your house with a Realtor, it is typical to be charged a service fee equal to one month's rent. So keep that in mind when you go to list. The advantage of listing with a Realtor is that all tenants are pre-screened before signing a lease with a credit check, application and in some cases background checks as well, to ensure you the best tenant for your property. When selecting your Realtor make sure they protect your investment with an electronic lock box and advertise it for rent!
