Also, knocking on doors (aka "driving for dollars") is an outdated way of doing this and honestly isn't worth your time.

 I love door knocking and meeting home owners and getting connected with residents in target areas for projects.I am specifically looking for land, and often find all types of real state for sale such as single family homes with air b&b rental units, duplexes, triplexes, multi-family, apartments, vacant homes, all kinds of things by asking owners if they would sell their own home or if they know of anyone selling land, a home, business, apartments, or commercial space.In the Miami area.. what is the best way you are using to find buyers for these type of deals to sell as a lead or wholesale (not going to list these as a realtor), what groups do you network in to find buyers?

At very least, you should provide a link to your LinkedIn profile here on your BiggerPockets page, along with a phone number, email address, favorite carrier pigeon name, and any other reliable method to reach you.You never know just when money will come knocking, but it rarely knocks twice...

Next Step is door knocking

Also, knocking on doors (aka "driving for dollars") is an outdated way of doing this and honestly isn't worth your time.

So you need to be knocking on more doors than before.

Things like driving for dollars, cold calling and door knocking are all low cost methods of finding and contacting potential leads.

Do not make special trips for something like that when you know the next issue will be coming up soon, knock them both out at once. 

I was door-knocking yesterday to get a feel of the neighborhood I am planning to invest in.

I went up to knock but no one answered, I think no one lives there due to the condition of the house.
