Easiest way to find UNLISTED Home Phone # ?

[sniper]

The search engines I used suggested that the owner has an unlisted home phone number. 

Is there an affordable (cheap) way to get it?
Please advise, it's an out-of-state owner of the abandoned property. I sent them a letter, received no response, want to be proactive and call them up.

Search and try and find a relative of the owner and try and talk to them. Im currently in the same situation but the relative never picks up the phone.

You already know this, but you might have to send several letter/postcard to get a response.  Just typical sales strategy.

Not sure if I saw in on this site or elsewhere...throw some hard candy in the envelope.  Makes it non-flat and increases the odds of it getting opened.

Another thing.  Add a piece of cardboard to the envelope (8x10) and write large on the outside "Picture of your XX state house enclosed"
Inside put:
A picture of the house, a picture of a check.  Ask him to call you to fill in the check amount.  Tell him BOTH are accurate pictures of his house....'cause they are.

that's a good idea
