Sending letters only to pre-foreclosures in farm area

[Chris Brown]

Good morning,

I am fine tuning my strategy for my first mailing campaign. I plan to use list providers to create my lists and one I am working on is homes that are in pre-foreclosure or foreclosure prior to auction. This list is only about 70 owners for my area and I am curious if I am being too specific? The strategy of the letters would be to get the owner in conversation prior to them going to the courthouse steps and hopefully making a mutually beneficial deal that can keep them from being foreclosed. 

I plan to widen my net and provide more saturation, but I thought a pre-foreclosure list like this would give me a good trial run before sending to the big list.

Any thoughts on my ideas would be appreciated.

Thanks

Chris
