Direct Marketing question

[Vicki S.]

I found a list a properties which the owner is not occupying the property from the city and have been doing some research on direct mailing to absentee owners.

However I don't have a lot of confidence to begin mailing the letters, post cards, I see a lot of owners living within the city or the adjacent city of my targeted properties which they can easily ask a realtor to sell their properties and why would they sell the properties to me with a discount?

Anyone know the effectiveness for getting responses and deals? any guidence would be appreciate.
