@Romeo Agnew hard money or private lenders (friends, family, and associates) will generally be your best bet.

Bet of luck!

@Jonathan SedaIt's definitely possible to package into a blanket loan, I agree that a local / regional bank is your best bet. 

Sure placing an ad on social media will get you a lead here and there but I bet these leads will eventually turn to Google to check out their options.

However I wouldn't bet TOO much on appreciation.

This may sound a bit strange because I am a real estate broker as well, and I do enjoy getting paid my commissions, but your best bet is to deploy some type of marketing to attract the motivated sellers for the types of properties you'd like to purchase

Low occupancy is my focus (i.e. if i buy a SFR for airbnb in Atlanta, where is my best bet?)

If it was medical and most actually are medical, then when the bankruptcy is discharged, they can't file again for 7 or 8 years so they are now a pretty safe bet.

Once i get a list of targeted property owners names, physical and site addresses etc... what would be a good service to use  where I can upload my list and have all my postcard sent out with a schedule for recurring mail?

I bet they both will cover most of what you really need.
