It's normally not hard to win an eviction. 

I'm about to start a team of callers on these lists, but I don't want to waste their time or my time with these dead leads.I'm thinking of charging back the expense with my credit card company because I'm pretty disappointed.Does anyone have any solutions they'd recommend for getting accurate property owner phone numbers?

Winning their trust and saying that you're licensed and follow a code of ethics, unlike investors and others that may want to buy your home directly (they don't know the terms wholesalers).

It’s all about solving problems and creating win-win situations.

I know many folks that started a business with just a business card, telephone, a vehicle and ambition. 

Going to court could be long and expensive, and even if you win, enforcing it might be tough.

I don't accept credit card payments for this very reason.

The best advice on this topic, in my opinion, comes from 2 books:How to win friends and influence peopleNever eat aloneI am also looking for brokerages to work with or even experienced shadow / intern for to gain experience and additional knowledge.

That’s often a winning recipe. 

So I used 0% interest for a year credit cards to pay for cap ex things that popped up or a rehab etc.
