If you want to generate you own list of properties here is my advice.
My advice to new investors is to start wholesaling properties. First pick a neighborhood that you are either in or close to. Driver around all the streets and look for vacant houses. There should be some. Then look in the county assessors website to find the owners. it should give their name and mailing address. Send them a letter telling them you found their house to be apparently vacant. But if it is obviously abandoned, say so in the letter. Tell them you will pay them cash for a quick close.
As you mentioned above you contact a local RE Agent to give you a list of all the houses in that neighborhood that have sold in the last 5 years with all cash. This typically is investors. Then again go to the assessors website and find their name and mailing address.
Once you get a response from the seller of the vacant house, negotiate a deal to buy it for all cash. Then immediately contact all the cash buyers you just found that buy properties in that neighborhood and tell them about the house and would they be interested in buying it.
Once you have done all that with that neighborhood, go to the next one and 'rinse and repeat.'
I hope this helps.
