Vetting Potential Seller By Phone

[Brandon G.]

I read @Jerry Puckett 's script that was posted and it's really a big help! When asking them what they think their house is worth and how much repairs it requires and how little they would accept, and how much they owe, what are some good rules of thumb to determine if they qualify for a face to face meeting? 

So if based on the conversation, we believe the house can sell for $150,000 and I want about $20,000 on the deal, what is the most they should owe on the mortgage before we move to the next step?
