I hate to state the obvious but...
You must always consider the lead source if the leads appear suspect....
I've heard of probate leads, absentee owner leads,
I'm curious what constitutes a motivated seller lead? First Ive ever heard of that.
Let's role play a little:
Antonio - Hello, I'm calling because I'm interested in purchasing the property @ 123 Main Street. Is now a good time to talk?
Seller - Yes
Antonio - Do you currently owe more than the house is currently worth? ( this will tell you if you need to start a short sale process or if you even want to move forward)
Antonio - Can you tell me a little about the property? How many beds and baths? garage? lot size? oil? gas?
Seller - Gives you all the info
Antonio - Does it need any repairs? Roof, furnance, paint? windows?
Seller - Gives you all the info.
Antonio - What is the lowest price you will sell this house for today.
Seller - Gives you a number.
Antonio - If I were to come to your house tomorrow morning with a suitcase full of cash is that the best price you could do?
Seller - Often gives a lower number.
There are a few ways to have this conversation but you get the gist of it. Often times sellers are upside down so thats why I used the " Do you currently owe more than the house is currently worth?" scenario.
