I also sent a professional letter that a friend of mine sent me and a postcard I created. 

Looking for recommendations on who people use for sending out postcards and letters for off market properties. 

I sent out a small post card mailing yesterday and will do so again in 2 weeks. 

Mailers, like a postcard or newsletters, or bulk electronic marketing materials, like email or text messages, allow you to reach even more potential clients than you can through networking alone.Postcards, flyers, and business cards pinned to bulletin boards at coffee shops are all examples of a prospecting tip called cold canvassing.

People constantly tell me that they've been getting a ton of letters/postcards etc...

Download the Deal Machine app to log these properties and to learn who the owners are, skip-trace their contact information, and mail post cards to their home. 

If you’re not sure how, call the “We buy houses numbers” you see on signs or get on postcards and tell them you want to be added to their buyer list.

Postcards vs.

a trailer owner called me from a post card I sent out so I spent quite a bit of time looking into it and unfortunately most trailer parks require the trailer to be owner occupied. 

I posted a postcard on people's doors in my neighborhood saying I am a cash investor.
