I mail anywhere between 12,000--20,000 yellow letters every month. I have PATLive as an answering service handling the initial call and gathering basic info. (Reason for selling, current condition of the home, how quickly they need to sell, asking price, is that price negotiable) I would tell them that you buy house in their area and that you send letters to people just to see if they're interested in selling. If they say "I'd sell for the right price", it's probably not the motivated seller you're looking for. I've actually had a police officer from a Township in Cincinnati, OH call me because my letter apparently scared one of their residents, lol. Someone mentioned before me to buy Michael Quarles course. He has some good info but I personally don't believe in his philosophy or strategies. You can find all of the training you're looking for by listening to podcasts. Joe McCall, Sean Terry, Tom Kroll, Michael Quarles, Biggerpockets, Investor Carrot and so on and so on. Search YouTube for "motivated seller calls" or "" asking to motivated sellers" and you'll probably find some live calls. Once you get their address, get off the phone with them to do some research. Once you figure out the range you'll be offering, call them back and tell them where you're at. Don't waste your time going to look at the houses that the owner is expecting double your figure. I did that when I was first mailing. I ran to every house that called and waste a ton of my time and the sellers. 95% of the deals I contract now are done over the phone, sight unseen. Hope this helps!
