After cold-calling hundreds of houses in one of my farm areas here in Miami, I received a call back from the son who told me I called asking about his mothers home and that she was interested in selling. 

Just be careful to know the related laws cold, as a mistake in this area may be a very costly lawsuit.

Another tip would be to check the properties going to auction in the paper and on websites (such as hubzu or auction.com) and cold call the owner directly to see if they would be interested in selling. 

Does anyone have any good feedback about how to build rapport when you're reaching out to someone on a cold call or through some type of marketing where they are not coming to you?

What type of cold calling follow up sequence does everyone use for warm and hot leads ?

Cold call, cold call, cold call4.

This is the splash of cold water I need at this moment.  

Maybe go to a REIA and ask local investors who they are using.Marketing really depends on your allocated budget but there are a lot of good options such as; direct mail, cold calling, so on etc.Good luck!

Especially with the price range and size properties you are looking for cold calling and direct mail marketing could be very effective for you.Best!

Always find it hard to connect with the physical owner when cold calling parks.
