How would I introduce myself to landlords in my area? Also, will property management companies give me names of landlords? If so, how do I approach them?

get a list of them thru a list broker (like salesgenie or melissadata) and send them a postcard offerring your services.

Get access to mls and download a list of all properties where the mailing address differs from the property address (tax records should list owners name and address).

Network at real estate investors associations

list broker is going to be alot easier then calling a bunch of property managers they probably wouldnt give you there info anyways not knowing who you areā€¦
