Do you guys think using data on a tape will find motivated sellers to mail to. 

The only times I have been asked to name a price or make an offer, the sellers were not motivated to sell and they are usually not cool about it.  :-) But when the owner talks about the house, is open about repairs needed, what they owe, etc., I have found most to be realistic when it comes to what they want.  

Fortunately you own real estate in California, so your property taxes did not go up 20%.(1) But don't put "I want to acquire more real estate for my family, in order to expand the Han Dynasty" in your cash out refinance motivation letter to the mortgage underwriter, even if your name is Han, she will not get the joke, will think it is "previously undisclosed self-employment" and will call for two years of business tax returns for the Han Dynasty!

Max Matsuk I'd suggest analyzing deals in the area first so you know what to offer when you get your first motivated seller.

Money is a big motivator.  

Since I gain critical and sensitive information from clients about their financial situation, it's easy to come across people who could possibly be motivated.
