FB Groups, download Meetup ap ( thats the name of the app) also a nice little explicit book on wholesaling , "Flip , by (Nick Ruiz) , and ************* (Guru and pioneer on Real Estate) he has like a mastermind, and even here  in BP Local Meetups

Cell phone is plugged in one outlet.

At least it's a real house.One thing no one else suggested you might explore, is Next Door app.
