My seller needs to see the house but is not under contract yet

[Marquell Jones]

I'm doing an assignment deal and I have 1 potential buyer. The end buyer has not seen the property, well not in person.  So he doesn't have a great estimate on the place or anything. I don't either because I don't have a GC but the end buyer does. I'm more afraid that if it's not under contract before he sees it that he could just steal it. I'm lost!! Because I'm ready to do absolute numbers and get this deal done.
